answer：Alright, so I have this problem about a literature professor studying themes in Shakespeare's plays and their impact on modern literature. There are two parts to the problem. Let me try to tackle them one by one.Starting with part 1. The professor is looking at three themes: power (P), love (L), and betrayal (B). Each has a weight: ( w_P, w_L, w_B ). The total thematic impact ( T ) is given by this formula:[T = frac{37}{100} left( 0.7w_P + 0.9w_L + 0.6w_B right)]And we know that the sum of the weights is 1, so ( w_P + w_L + w_B = 1 ). Also, it's given that ( w_P = 2w_L ) and ( w_B = 1 - 3w_L ). So, I need to express ( T ) in terms of a single variable, ( w_L ).First, let me write down the relationships:1. ( w_P = 2w_L )2. ( w_B = 1 - 3w_L )Since ( w_P + w_L + w_B = 1 ), substituting the expressions for ( w_P ) and ( w_B ) should satisfy this equation.Let me check:( 2w_L + w_L + (1 - 3w_L) = 1 )Simplify:( 2w_L + w_L + 1 - 3w_L = 1 )Combine like terms:( (2w_L + w_L - 3w_L) + 1 = 1 )Which simplifies to:( 0w_L + 1 = 1 )So, 1 = 1. That checks out. So, the expressions for ( w_P ) and ( w_B ) in terms of ( w_L ) are consistent with the normalization condition.Now, let's substitute ( w_P ) and ( w_B ) into the formula for ( T ):[T = frac{37}{100} left( 0.7(2w_L) + 0.9w_L + 0.6(1 - 3w_L) right)]Let me compute each term step by step.First, compute ( 0.7(2w_L) ):( 0.7 * 2 = 1.4 ), so this term is ( 1.4w_L ).Next, ( 0.9w_L ) is straightforward; that's just ( 0.9w_L ).Then, ( 0.6(1 - 3w_L) ):Multiply 0.6 by 1: 0.6Multiply 0.6 by -3w_L: -1.8w_LSo, this term is ( 0.6 - 1.8w_L ).Now, combine all these terms:( 1.4w_L + 0.9w_L + 0.6 - 1.8w_L )Let me add the coefficients of ( w_L ):1.4 + 0.9 - 1.8 = (1.4 + 0.9) - 1.8 = 2.3 - 1.8 = 0.5So, the expression becomes:( 0.5w_L + 0.6 )Therefore, the entire expression for ( T ) is:[T = frac{37}{100} (0.5w_L + 0.6)]I can write this as:[T = frac{37}{100} times 0.5w_L + frac{37}{100} times 0.6]Calculating each term:( frac{37}{100} times 0.5 = frac{37}{200} = 0.185 )( frac{37}{100} times 0.6 = frac{22.2}{100} = 0.222 )So, putting it all together:[T = 0.185w_L + 0.222]Wait, let me verify that multiplication:( 37/100 * 0.5 = (37 * 0.5)/100 = 18.5/100 = 0.185 ). That's correct.( 37/100 * 0.6 = (37 * 0.6)/100 = 22.2/100 = 0.222 ). Correct.So, yes, ( T = 0.185w_L + 0.222 ).Alternatively, I can write this as:[T = 0.185w_L + 0.222]But perhaps the problem expects it in fractional form instead of decimal? Let me see.0.185 is 37/200, since 37 divided by 200 is 0.185.0.222 is approximately 222/1000, which simplifies to 111/500.But maybe it's better to leave it as decimals since the original coefficients were given as decimals.So, I think that's the expression for ( T ) in terms of ( w_L ).Moving on to part 2. We need to find the determinant of the covariance matrix ( C ). The matrix is given as:[C = begin{bmatrix}sigma^2_P & rho_{PL} sigma_P sigma_L & rho_{PB} sigma_P sigma_B rho_{PL} sigma_P sigma_L & sigma^2_L & rho_{LB} sigma_L sigma_B rho_{PB} sigma_P sigma_B & rho_{LB} sigma_L sigma_B & sigma^2_Bend{bmatrix}]Given:- ( sigma_P = 0.5 )- ( sigma_L = 0.7 )- ( sigma_B = 0.4 )- All correlation coefficients ( rho_{PL}, rho_{PB}, rho_{LB} = 0.3 )So, first, let's compute each element of the covariance matrix.First, compute the variances:- ( sigma^2_P = (0.5)^2 = 0.25 )- ( sigma^2_L = (0.7)^2 = 0.49 )- ( sigma^2_B = (0.4)^2 = 0.16 )Next, compute the covariance terms:- ( rho_{PL} sigma_P sigma_L = 0.3 * 0.5 * 0.7 = 0.3 * 0.35 = 0.105 )- ( rho_{PB} sigma_P sigma_B = 0.3 * 0.5 * 0.4 = 0.3 * 0.2 = 0.06 )- ( rho_{LB} sigma_L sigma_B = 0.3 * 0.7 * 0.4 = 0.3 * 0.28 = 0.084 )So, plugging these into the covariance matrix ( C ):[C = begin{bmatrix}0.25 & 0.105 & 0.06 0.105 & 0.49 & 0.084 0.06 & 0.084 & 0.16end{bmatrix}]Now, we need to compute the determinant of this 3x3 matrix.The determinant of a 3x3 matrix can be calculated using the rule of Sarrus or the general formula. I think the general formula is more straightforward here.The determinant of a 3x3 matrix:[begin{bmatrix}a & b & c d & e & f g & h & iend{bmatrix}]is:( a(ei - fh) - b(di - fg) + c(dh - eg) )So, applying this to our matrix ( C ):Let me label the elements:- a = 0.25- b = 0.105- c = 0.06- d = 0.105- e = 0.49- f = 0.084- g = 0.06- h = 0.084- i = 0.16So, determinant ( |C| = a(ei - fh) - b(di - fg) + c(dh - eg) )Let's compute each part step by step.First, compute ( ei - fh ):( e = 0.49 ), ( i = 0.16 ), so ( ei = 0.49 * 0.16 = 0.0784 )( f = 0.084 ), ( h = 0.084 ), so ( fh = 0.084 * 0.084 = 0.007056 )Thus, ( ei - fh = 0.0784 - 0.007056 = 0.071344 )Next, compute ( di - fg ):( d = 0.105 ), ( i = 0.16 ), so ( di = 0.105 * 0.16 = 0.0168 )( f = 0.084 ), ( g = 0.06 ), so ( fg = 0.084 * 0.06 = 0.00504 )Thus, ( di - fg = 0.0168 - 0.00504 = 0.01176 )Next, compute ( dh - eg ):( d = 0.105 ), ( h = 0.084 ), so ( dh = 0.105 * 0.084 = 0.00882 )( e = 0.49 ), ( g = 0.06 ), so ( eg = 0.49 * 0.06 = 0.0294 )Thus, ( dh - eg = 0.00882 - 0.0294 = -0.02058 )Now, plug these back into the determinant formula:( |C| = a(ei - fh) - b(di - fg) + c(dh - eg) )Substitute the values:( |C| = 0.25 * 0.071344 - 0.105 * 0.01176 + 0.06 * (-0.02058) )Compute each term:First term: ( 0.25 * 0.071344 = 0.017836 )Second term: ( -0.105 * 0.01176 = -0.0012324 )Third term: ( 0.06 * (-0.02058) = -0.0012348 )Now, add them all together:( 0.017836 - 0.0012324 - 0.0012348 )Compute step by step:First, ( 0.017836 - 0.0012324 = 0.0166036 )Then, subtract the third term: ( 0.0166036 - 0.0012348 = 0.0153688 )So, the determinant is approximately 0.0153688.But let me check my calculations again because determinants can be tricky.Wait, let me verify each multiplication:First term: 0.25 * 0.0713440.25 * 0.07 = 0.01750.25 * 0.001344 = 0.000336So, total is 0.0175 + 0.000336 = 0.017836. Correct.Second term: -0.105 * 0.01176Compute 0.105 * 0.01176:0.1 * 0.01176 = 0.0011760.005 * 0.01176 = 0.0000588So, total is 0.001176 + 0.0000588 = 0.0012348But since it's negative, it's -0.0012348Third term: 0.06 * (-0.02058) = -0.0012348So, adding all together:0.017836 - 0.0012348 - 0.0012348Compute 0.017836 - 0.0012348 = 0.0166012Then, 0.0166012 - 0.0012348 = 0.0153664So, approximately 0.0153664.Rounding to, say, 6 decimal places, it's 0.015366.But maybe we can express it as a fraction or a more precise decimal.Alternatively, perhaps I made a miscalculation in the determinant formula.Wait, let me double-check the determinant formula.Yes, the formula is:( a(ei - fh) - b(di - fg) + c(dh - eg) )Which is correct.So, plugging in:0.25*(0.49*0.16 - 0.084*0.084) - 0.105*(0.105*0.16 - 0.084*0.06) + 0.06*(0.105*0.084 - 0.49*0.06)Wait, let me compute each bracket again.First bracket: ( ei - fh = 0.49*0.16 - 0.084*0.084 )0.49*0.16: 0.07840.084*0.084: 0.007056So, 0.0784 - 0.007056 = 0.071344Second bracket: ( di - fg = 0.105*0.16 - 0.084*0.06 )0.105*0.16: 0.01680.084*0.06: 0.00504So, 0.0168 - 0.00504 = 0.01176Third bracket: ( dh - eg = 0.105*0.084 - 0.49*0.06 )0.105*0.084: 0.008820.49*0.06: 0.0294So, 0.00882 - 0.0294 = -0.02058So, all brackets are correct.Now, plugging into determinant:0.25*0.071344 = 0.017836-0.105*0.01176 = -0.00123480.06*(-0.02058) = -0.0012348Adding them up: 0.017836 - 0.0012348 - 0.0012348 = 0.0153664So, approximately 0.0153664.Expressed as a decimal, that's roughly 0.015366.Alternatively, if we want to express it as a fraction, let's see:0.0153664 is approximately 0.015366, which is roughly 15366/1000000.Simplify numerator and denominator by dividing numerator and denominator by 2:7683/500000Check if 7683 and 500000 have any common factors.7683 ÷ 3 = 2561, which is a prime? Maybe.500000 ÷ 3 is not an integer, so 3 is a factor of numerator but not denominator.So, 7683/500000 is the simplified fraction.But perhaps it's better to leave it as a decimal since the original values were decimals.So, the determinant is approximately 0.015366.But let me see if I can compute it more precisely.Wait, perhaps I can use another method, like expanding the determinant along a different row or column to see if I get the same result.Alternatively, maybe compute it using the formula for the determinant of a covariance matrix with equal correlations.Wait, in this case, the covariance matrix is a 3x3 matrix with equal correlations (0.3) between each pair.There's a formula for the determinant of such a matrix.In general, for a covariance matrix with variances ( sigma_1^2, sigma_2^2, sigma_3^2 ) and equal correlations ( rho ), the determinant is:( (sigma_1^2 sigma_2^2 sigma_3^2) (1 - rho^2) (1 + 2rho) )Wait, is that correct?Wait, let me recall.For a 3x3 matrix with diagonal elements ( sigma_i^2 ) and off-diagonal elements ( rho sigma_i sigma_j ), the determinant can be computed as:( (sigma_1^2 sigma_2^2 sigma_3^2) times (1 - rho^2)^2 (1 + 2rho) )Wait, no, maybe not exactly.Alternatively, the determinant can be calculated as:( sigma_1^2 sigma_2^2 sigma_3^2 times left(1 + 2rho + 3rho^2right) ) or something like that.Wait, perhaps it's better to compute it step by step.Alternatively, perhaps use the fact that the determinant of a covariance matrix with equal correlations is given by:( sigma_P^2 sigma_L^2 sigma_B^2 times (1 - rho^2)^2 (1 + 2rho) )Wait, let me check.Wait, actually, for a 3x3 matrix with diagonal elements ( a, b, c ) and off-diagonal elements ( d, e, f ), the determinant is:( a(b c - e^2) - d(d c - e f) + f(d e - b f) )But in our case, all off-diagonal elements are equal in terms of correlation, but scaled by the product of standard deviations.Wait, perhaps it's better to just compute it numerically as I did before.But since I already computed it numerically and got approximately 0.015366, maybe I can just stick with that.Alternatively, perhaps compute it using another method.Wait, another way to compute the determinant is to factor out the variances.But I think it's getting too complicated.Alternatively, perhaps use the formula for the determinant of a 3x3 matrix with equal correlations.Wait, I think the formula is:For a 3x3 matrix with diagonal elements ( sigma_i^2 ) and off-diagonal elements ( rho sigma_i sigma_j ), the determinant is:( (sigma_1 sigma_2 sigma_3)^2 [1 - 3rho^2 + 2rho^3] )Wait, let me test this formula.Given that all off-diagonal elements are ( rho sigma_i sigma_j ), so in our case, ( rho = 0.3 ), and ( sigma_P = 0.5 ), ( sigma_L = 0.7 ), ( sigma_B = 0.4 ).So, first, compute ( (sigma_P sigma_L sigma_B)^2 ):( (0.5 * 0.7 * 0.4)^2 = (0.14)^2 = 0.0196 )Then, compute ( 1 - 3rho^2 + 2rho^3 ):( 1 - 3*(0.3)^2 + 2*(0.3)^3 = 1 - 3*0.09 + 2*0.027 = 1 - 0.27 + 0.054 = 1 - 0.27 = 0.73 + 0.054 = 0.784 )So, determinant is ( 0.0196 * 0.784 = )Compute 0.0196 * 0.784:First, 0.01 * 0.784 = 0.007840.0096 * 0.784 = ?Wait, 0.0196 is 0.01 + 0.0096So, 0.01 * 0.784 = 0.007840.0096 * 0.784:Compute 0.01 * 0.784 = 0.00784Subtract 0.0004 * 0.784 = 0.0003136So, 0.00784 - 0.0003136 = 0.0075264So, total determinant is 0.00784 + 0.0075264 = 0.0153664Which matches the previous calculation.So, the determinant is 0.0153664.So, that's consistent.Therefore, the determinant of the covariance matrix ( C ) is approximately 0.0153664.Expressed as a decimal, it's approximately 0.015366.Alternatively, if we want to write it as a fraction, as I did earlier, it's 7683/500000, but that's a bit unwieldy.So, probably, the answer is 0.015366 or approximately 0.01537.But let me check if I can write it more precisely.Wait, 0.0153664 is approximately 0.015366, which is 0.015366.Alternatively, if we want to express it as a fraction, 0.0153664 is equal to 153664/10000000, which simplifies to 19208/1250000, but that's still not very clean.So, perhaps the best way is to present it as approximately 0.01537.Alternatively, since the original values were given to two decimal places (0.5, 0.7, 0.4, and 0.3), perhaps we can round the determinant to, say, four decimal places: 0.0154.But let me see:0.0153664 is approximately 0.01537 when rounded to five decimal places.But if we round to four decimal places, it's 0.0154.Alternatively, the exact value is 0.0153664, which is approximately 0.01537.But to be precise, maybe we can write it as 0.015366.But in any case, the exact value is 0.0153664, so depending on the required precision, we can present it accordingly.So, summarizing:1. The expected combined thematic impact ( T ) expressed in terms of ( w_L ) is ( T = 0.185w_L + 0.222 ).2. The determinant of the covariance matrix ( C ) is approximately 0.015366.But let me just double-check the first part again to make sure I didn't make any mistakes.Starting with ( T = frac{37}{100}(0.7w_P + 0.9w_L + 0.6w_B) )Given ( w_P = 2w_L ) and ( w_B = 1 - 3w_L ), substitute:( 0.7*2w_L = 1.4w_L )( 0.9w_L ) remains as is.( 0.6*(1 - 3w_L) = 0.6 - 1.8w_L )Adding them up: 1.4w_L + 0.9w_L - 1.8w_L + 0.6 = (1.4 + 0.9 - 1.8)w_L + 0.6 = 0.5w_L + 0.6Multiply by 37/100: 0.37*(0.5w_L + 0.6) = 0.185w_L + 0.222Yes, that's correct.So, I think both parts are correctly solved.**Final Answer**1. The expected combined thematic impact is (boxed{0.185w_L + 0.222}).2. The determinant of the covariance matrix is (boxed{0.01537}).

answer：First, I need to identify all the components of the therapy session and their respective durations.There are 8 activities, each lasting 15 minutes. So, the total time for activities is 8 multiplied by 15 minutes, which equals 120 minutes.Next, there's a 30-minute discussion period for clients to share their thoughts and experiences.Additionally, there's a 15-minute introduction at the start of the session and a 10-minute closing remarks at the end.To find the total duration of the session, I'll add up all these components: 120 minutes for activities, 30 minutes for discussion, 15 minutes for introductions, and 10 minutes for closing remarks. Adding these together: 120 + 30 + 15 + 10 equals 175 minutes.Therefore, each therapy session lasts a total of 175 minutes.

answer：First, I need to determine the weight of a single neuron. The total weight of the brain is 1.4 kilograms, which is equivalent to 1400 grams. The brain contains approximately 86 billion neurons. To find the weight of one neuron, I will divide the total weight by the number of neurons.Next, to find the weight of a group of 1 million neurons, I will take the weight of a single neuron and multiply it by 1,000,000. This will give me the total weight for that group.Finally, I will present both calculations clearly to provide the answers.

answer：Okay, so I have this problem about a screenwriter planning a film festival in Edinburgh. She's showing her five latest films, each with unique durations, and there are intermissions between each film that are all the same length. The total duration of the festival is 10 hours, and the sum of all the film durations is 7.5 hours. I need to find the duration of each intermission, which is denoted as ( I ).Alright, let's break this down. First, there are five films, so that means there are four intermissions between them. Because each intermission is the same length, if I can find the total time spent on intermissions, I can divide by four to get ( I ).The total duration of the festival is 10 hours. This includes both the films and the intermissions. The films add up to 7.5 hours, so the remaining time must be the intermissions. Let me write that as an equation.Total time = Sum of film durations + Sum of intermission durationsSo,10 = 7.5 + (number of intermissions × I)Since there are five films, there are four intermissions. So,10 = 7.5 + 4INow, I can solve for ( I ). Subtract 7.5 from both sides:10 - 7.5 = 4I2.5 = 4IThen, divide both sides by 4:I = 2.5 / 4Let me compute that. 2.5 divided by 4 is 0.625. So, ( I = 0.625 ) hours. To convert that into minutes, since 0.625 hours is 0.625 × 60 minutes, which is 37.5 minutes. Hmm, that seems reasonable for an intermission.Wait, let me double-check my steps. Total time is 10 hours. Films take 7.5 hours, so intermissions take 2.5 hours. There are four intermissions, so each is 2.5 / 4 = 0.625 hours. Yep, that seems correct.So, for part 1, the duration of each intermission is 0.625 hours, which is 37.5 minutes.Moving on to part 2. It asks for the probability that a randomly chosen attendee will arrive during an intermission. The attendee arrives at any point during the total 10-hour duration with uniform probability. So, the probability is just the total intermission time divided by the total duration.Total intermission time is 4I, which we know is 2.5 hours. The total duration is 10 hours. So, the probability ( P ) is:( P = frac{2.5}{10} = 0.25 )So, 25% chance. Let me think if that makes sense. Since intermissions take up 2.5 hours out of 10, that's a quarter of the time, so 25% probability. That seems straightforward.Wait, another way to think about it: each intermission is 0.625 hours, and there are four of them. So, total intermission time is 4 × 0.625 = 2.5 hours. So, 2.5 / 10 = 0.25. Yep, same result.So, the probability is 0.25 or 25%.I think that's it. I don't see any mistakes in my reasoning.**Final Answer**1. The duration of each intermission is boxed{0.625} hours.2. The probability that an attendee arrives during an intermission is boxed{0.25}.

answer：First, I need to determine how many flyers each gym and each sports store will receive. There are 8 gyms and 4 sports stores, making a total of 12 locations.Let’s denote the number of flyers each gym receives as G. Since each sports store receives twice as many flyers as each gym, each sports store will receive 2G flyers.The total number of flyers distributed to gyms is 8G, and the total distributed to sports stores is 4 × 2G = 8G. Therefore, the total flyers distributed is 8G + 8G = 16G.Given that there are 1,200 flyers in total, I can set up the equation 16G = 1,200. Solving for G, I divide both sides by 16, which gives G = 75.Therefore, each gym will receive 75 flyers, and each sports store will receive 150 flyers.

answer：Alright, so I have this problem where a hospital CEO wants to maximize the total revenue from three departments: Emergency, Surgery, and Outpatient. Each department has its own revenue model, and there's a total capacity constraint of 10,000 patients, surgeries, and visits combined. I need to figure out the optimal number of patients, surgeries, and visits to maximize the total revenue.First, let me write down the given information to make sure I have everything clear.The revenue models are:1. Emergency Department: [ R_E = alpha_E cdot p_E - beta_E cdot p_E^{0.8} ] where ( alpha_E = 500 ) and ( beta_E = 50 ).2. Surgery Department: [ R_S = alpha_S cdot s_S - gamma_S cdot s_S^{1.2} ] where ( alpha_S = 2000 ) and ( gamma_S = 300 ).3. Outpatient Department: [ R_O = alpha_O cdot v_O - delta_O cdot v_O ] where ( alpha_O = 100 ) and ( delta_O = 20 ).Total revenue is the sum of these three:[R = R_E + R_S + R_O]And the constraints are:[p_E + s_S + v_O leq 10,000]and[p_E, s_S, v_O geq 0]Okay, so the goal is to maximize ( R ) given these constraints. This seems like an optimization problem with three variables and one inequality constraint. Since the total capacity is 10,000, I might need to consider how to distribute this capacity among the three departments to maximize the total revenue.I remember that for optimization problems with constraints, one common method is to use Lagrange multipliers. But since this is a problem with three variables and one constraint, maybe I can set up the Lagrangian function and take partial derivatives with respect to each variable and the Lagrange multiplier.Alternatively, since the total capacity is 10,000, maybe I can express one variable in terms of the other two and substitute it into the total revenue function, turning it into a two-variable optimization problem. That might be simpler.Let me think about both approaches.First, let's try the Lagrangian method. The Lagrangian function ( mathcal{L} ) would be:[mathcal{L} = R_E + R_S + R_O - lambda (p_E + s_S + v_O - 10,000)]Wait, actually, since the constraint is ( p_E + s_S + v_O leq 10,000 ), and we are maximizing, the maximum will occur at the boundary, so we can set ( p_E + s_S + v_O = 10,000 ).So, the Lagrangian becomes:[mathcal{L} = 500 p_E - 50 p_E^{0.8} + 2000 s_S - 300 s_S^{1.2} + 100 v_O - 20 v_O - lambda (p_E + s_S + v_O - 10,000)]Simplify ( R_O ):[R_O = 100 v_O - 20 v_O = 80 v_O]So, the Lagrangian simplifies to:[mathcal{L} = 500 p_E - 50 p_E^{0.8} + 2000 s_S - 300 s_S^{1.2} + 80 v_O - lambda (p_E + s_S + v_O - 10,000)]Now, take partial derivatives with respect to ( p_E ), ( s_S ), ( v_O ), and ( lambda ), set them equal to zero, and solve.Let's compute each partial derivative.1. Partial derivative with respect to ( p_E ):[frac{partial mathcal{L}}{partial p_E} = 500 - 50 cdot 0.8 p_E^{-0.2} - lambda = 0]Simplify:[500 - 40 p_E^{-0.2} - lambda = 0 quad (1)]2. Partial derivative with respect to ( s_S ):[frac{partial mathcal{L}}{partial s_S} = 2000 - 300 cdot 1.2 s_S^{0.2} - lambda = 0]Simplify:[2000 - 360 s_S^{0.2} - lambda = 0 quad (2)]3. Partial derivative with respect to ( v_O ):[frac{partial mathcal{L}}{partial v_O} = 80 - lambda = 0]So,[80 - lambda = 0 implies lambda = 80 quad (3)]4. Partial derivative with respect to ( lambda ):[frac{partial mathcal{L}}{partial lambda} = -(p_E + s_S + v_O - 10,000) = 0]Which gives:[p_E + s_S + v_O = 10,000 quad (4)]Now, from equation (3), we have ( lambda = 80 ). Let's substitute this into equations (1) and (2).From equation (1):[500 - 40 p_E^{-0.2} - 80 = 0]Simplify:[420 - 40 p_E^{-0.2} = 0][40 p_E^{-0.2} = 420][p_E^{-0.2} = frac{420}{40} = 10.5]Taking both sides to the power of -5 (since -0.2 is -1/5):[p_E = (10.5)^{-5}]Wait, that can't be right. Let me check my steps.Wait, ( p_E^{-0.2} = 10.5 ), which is the same as ( p_E^{-1/5} = 10.5 ). So, to solve for ( p_E ), we can take both sides to the power of -5:[p_E = (10.5)^{-5}]But 10.5 to the power of -5 is a very small number, which doesn't make sense in this context because the number of patients can't be a fraction less than 1. That suggests I might have made a mistake in my calculations.Wait, let's go back.Equation (1):[500 - 40 p_E^{-0.2} - lambda = 0]With ( lambda = 80 ):[500 - 40 p_E^{-0.2} - 80 = 0]So,[420 = 40 p_E^{-0.2}]Divide both sides by 40:[10.5 = p_E^{-0.2}]Which is:[p_E^{-0.2} = 10.5]Taking both sides to the power of -5:[p_E = (10.5)^{-5}]But 10.5^-5 is approximately 1 / (10.5^5). Calculating 10.5^5:10.5^2 = 110.2510.5^3 = 110.25 * 10.5 ≈ 1157.62510.5^4 ≈ 1157.625 * 10.5 ≈ 12155.062510.5^5 ≈ 12155.0625 * 10.5 ≈ 127,628.15625So, p_E ≈ 1 / 127,628.15625 ≈ 0.00000783. That's way too small, which doesn't make sense because the number of patients can't be that low. There must be a mistake in my approach.Wait, perhaps I misapplied the derivative. Let me check the derivative of ( R_E ) with respect to ( p_E ).Given ( R_E = 500 p_E - 50 p_E^{0.8} ).The derivative is:[dR_E/dp_E = 500 - 50 * 0.8 p_E^{-0.2} = 500 - 40 p_E^{-0.2}]That seems correct.Similarly, for ( R_S = 2000 s_S - 300 s_S^{1.2} ).Derivative:[dR_S/ds_S = 2000 - 300 * 1.2 s_S^{0.2} = 2000 - 360 s_S^{0.2}]That also seems correct.For ( R_O = 80 v_O ), derivative is 80, correct.So, the partial derivatives are correct. Then, substituting ( lambda = 80 ) into equation (1) gives p_E ≈ 0.00000783, which is not feasible.Similarly, let's check equation (2):From equation (2):[2000 - 360 s_S^{0.2} - 80 = 0]Simplify:[1920 - 360 s_S^{0.2} = 0][360 s_S^{0.2} = 1920][s_S^{0.2} = 1920 / 360 = 5.333...]So,[s_S^{0.2} = 5.333...]Taking both sides to the power of 5:[s_S = (5.333...)^5]Calculating 5.333^5:First, 5.333^2 ≈ 28.4445.333^3 ≈ 28.444 * 5.333 ≈ 151.855.333^4 ≈ 151.85 * 5.333 ≈ 809.035.333^5 ≈ 809.03 * 5.333 ≈ 4323.43So, s_S ≈ 4323.43That's a large number, but let's see if it makes sense.Given that the total capacity is 10,000, if s_S is about 4323, then p_E is about 0.00000783, which is practically zero, and v_O would be 10,000 - 4323 - 0.00000783 ≈ 5677.But p_E being almost zero doesn't seem right because the Emergency Department might have some revenue even with a small number of patients.Wait, maybe the issue is that the marginal revenue for Emergency is higher than the Lagrange multiplier, so we should allocate more to Emergency. But according to the derivative, the marginal revenue is 500 - 40 p_E^{-0.2}, and when p_E is very small, p_E^{-0.2} is very large, so 40 p_E^{-0.2} is very large, making the marginal revenue negative. That suggests that increasing p_E would decrease revenue, which is why the optimal p_E is zero.Similarly, for Surgery, the marginal revenue is 2000 - 360 s_S^{0.2}. When s_S is zero, the marginal revenue is 2000, which is much higher than the Lagrange multiplier of 80, so we want to increase s_S until the marginal revenue equals 80.Wait, but in the Lagrangian method, the marginal revenue should equal the Lagrange multiplier, which is the shadow price of the constraint. So, for each department, the marginal revenue should equal the same lambda.But in this case, for Emergency, the marginal revenue is 500 - 40 p_E^{-0.2}, which when p_E is zero, is 500, which is way higher than lambda=80. So, according to this, we should increase p_E until the marginal revenue equals 80.Similarly, for Surgery, the marginal revenue is 2000 - 360 s_S^{0.2}, which when s_S is zero is 2000, much higher than 80, so we should increase s_S until its marginal revenue is 80.But when we set the marginal revenues equal to lambda=80, we get p_E ≈ 0.00000783 and s_S ≈ 4323.43, which seems inconsistent because p_E is almost zero, but the marginal revenue for p_E is 500 - 40 p_E^{-0.2}. If p_E is almost zero, p_E^{-0.2} is very large, making the marginal revenue negative, which would mean we should decrease p_E, but it's already at zero.Wait, perhaps the issue is that the Lagrangian method is not the right approach here because the functions might not be concave, or the constraints might not be binding in a certain way.Alternatively, maybe I should consider maximizing each department's revenue separately and then see how they fit into the total capacity.But that might not work because the departments are competing for the same capacity.Alternatively, maybe I can express v_O in terms of p_E and s_S: v_O = 10,000 - p_E - s_S, and substitute into the total revenue function, then take partial derivatives with respect to p_E and s_S.Let me try that approach.So, total revenue R is:[R = 500 p_E - 50 p_E^{0.8} + 2000 s_S - 300 s_S^{1.2} + 80 (10,000 - p_E - s_S)]Simplify:[R = 500 p_E - 50 p_E^{0.8} + 2000 s_S - 300 s_S^{1.2} + 800,000 - 80 p_E - 80 s_S]Combine like terms:[R = (500 - 80) p_E - 50 p_E^{0.8} + (2000 - 80) s_S - 300 s_S^{1.2} + 800,000]Simplify:[R = 420 p_E - 50 p_E^{0.8} + 1920 s_S - 300 s_S^{1.2} + 800,000]Now, we can take partial derivatives with respect to p_E and s_S and set them to zero.Partial derivative with respect to p_E:[frac{partial R}{partial p_E} = 420 - 50 * 0.8 p_E^{-0.2} = 420 - 40 p_E^{-0.2} = 0]So,[420 = 40 p_E^{-0.2}][p_E^{-0.2} = 420 / 40 = 10.5]Which is the same as before, leading to p_E ≈ 0.00000783, which is practically zero.Similarly, partial derivative with respect to s_S:[frac{partial R}{partial s_S} = 1920 - 300 * 1.2 s_S^{0.2} = 1920 - 360 s_S^{0.2} = 0]So,[360 s_S^{0.2} = 1920][s_S^{0.2} = 1920 / 360 = 5.333...]Which is the same as before, leading to s_S ≈ 4323.43.So, with p_E ≈ 0 and s_S ≈ 4323.43, then v_O = 10,000 - 0 - 4323.43 ≈ 5676.57.But wait, if p_E is zero, then the Emergency Department's revenue is zero. Is that really the optimal?Let me check the marginal revenues.For Emergency, the marginal revenue is 500 - 40 p_E^{-0.2}. When p_E is zero, this is 500, which is much higher than the marginal revenue for Surgery, which is 2000 - 360 s_S^{0.2}. When s_S is zero, that's 2000. Wait, but the Lagrange multiplier is 80, which is the shadow price of the capacity. So, each unit of capacity allocated to a department should contribute at least 80 to the revenue.But for Emergency, when p_E is zero, the marginal revenue is 500, which is much higher than 80, so we should allocate more to Emergency until its marginal revenue drops to 80.Similarly, for Surgery, when s_S is zero, the marginal revenue is 2000, which is higher than 80, so we should allocate more to Surgery until its marginal revenue drops to 80.But in our calculations, when we set the marginal revenues equal to 80, we get p_E ≈ 0.00000783 and s_S ≈ 4323.43, which seems to suggest that Emergency can't contribute much because its marginal revenue drops rapidly as p_E increases.Wait, let's think about the shape of the revenue functions.For Emergency, the revenue function is ( R_E = 500 p_E - 50 p_E^{0.8} ). The term ( p_E^{0.8} ) grows slower than linear, so the revenue increases with p_E but at a decreasing rate. The marginal revenue is 500 - 40 p_E^{-0.2}, which decreases as p_E increases because p_E^{-0.2} increases.Similarly, for Surgery, the revenue function is ( R_S = 2000 s_S - 300 s_S^{1.2} ). The term ( s_S^{1.2} ) grows faster than linear, so the revenue increases with s_S but at an increasing rate initially, but since the coefficient is negative, the revenue actually increases at a decreasing rate and eventually starts decreasing. The marginal revenue is 2000 - 360 s_S^{0.2}, which decreases as s_S increases.For Outpatient, the revenue is linear: ( R_O = 80 v_O ), so the marginal revenue is constant at 80.So, the Outpatient Department has a constant marginal revenue of 80, while Emergency and Surgery have decreasing marginal revenues. Therefore, to maximize total revenue, we should allocate as much as possible to the departments with the highest marginal revenues first.Initially, both Emergency and Surgery have higher marginal revenues than Outpatient. So, we should allocate to Emergency and Surgery until their marginal revenues drop to 80.But according to our earlier calculations, when we set the marginal revenues of Emergency and Surgery equal to 80, we get p_E ≈ 0.00000783 and s_S ≈ 4323.43. But p_E being almost zero suggests that the marginal revenue of Emergency drops very quickly, so even a small increase in p_E causes the marginal revenue to drop below 80.Wait, let's solve for p_E when marginal revenue equals 80:From equation (1):[500 - 40 p_E^{-0.2} = 80][40 p_E^{-0.2} = 420][p_E^{-0.2} = 10.5][p_E = (10.5)^{-5} ≈ 7.83 times 10^{-6}]So, p_E is approximately 0.00000783, which is practically zero. That means that even a tiny allocation to Emergency causes its marginal revenue to drop below 80, so it's not worth allocating any capacity to Emergency because the marginal revenue would immediately drop below the Outpatient's marginal revenue.Similarly, for Surgery, when we set the marginal revenue equal to 80:[2000 - 360 s_S^{0.2} = 80][360 s_S^{0.2} = 1920][s_S^{0.2} = 5.333...][s_S = (5.333...)^5 ≈ 4323.43]So, Surgery can take up about 4323.43 units, and the remaining capacity would go to Outpatient.Thus, the optimal allocation would be:p_E ≈ 0s_S ≈ 4323.43v_O ≈ 10,000 - 4323.43 ≈ 5676.57But let's check if this allocation indeed maximizes the total revenue.Let me calculate the total revenue with these values.First, calculate R_E:Since p_E ≈ 0, R_E ≈ 0.R_S = 2000 * 4323.43 - 300 * (4323.43)^{1.2}Let me compute (4323.43)^{1.2}.First, take natural log:ln(4323.43) ≈ 8.37Multiply by 1.2: 8.37 * 1.2 ≈ 10.044Exponentiate: e^{10.044} ≈ 22,000 (since e^{10} ≈ 22026)So, approximately, (4323.43)^{1.2} ≈ 22,000Thus, R_S ≈ 2000 * 4323.43 - 300 * 22,000Calculate:2000 * 4323.43 = 8,646,860300 * 22,000 = 6,600,000Thus, R_S ≈ 8,646,860 - 6,600,000 = 2,046,860R_O = 80 * 5676.57 ≈ 454,125.6Total revenue R ≈ 0 + 2,046,860 + 454,125.6 ≈ 2,500,985.6Now, let's check if allocating a small amount to Emergency would increase the total revenue.Suppose we allocate p_E = 1.Then, R_E = 500*1 - 50*(1)^{0.8} = 500 - 50 = 450Then, s_S would be 4323.43 - 1 = 4322.43 (but wait, no, because the total capacity is fixed at 10,000, so if we increase p_E by 1, we have to decrease either s_S or v_O by 1.But in our earlier allocation, s_S was already at 4323.43, which is the maximum that can be allocated to Surgery before its marginal revenue drops to 80. If we take 1 unit from Surgery and give it to Emergency, the change in revenue would be:ΔR = (R_E + Δp_E) + (R_S - Δs_S) + (R_O - Δv_O)But since we are only moving 1 unit from Surgery to Emergency, Δv_O remains the same.So, the change in revenue would be:ΔR = (500*1 - 50*1^{0.8}) - (2000*1 - 300*(4323.43 - 1)^{1.2} + 300*(4323.43)^{1.2})Wait, this is getting complicated. Alternatively, we can compute the marginal revenue of Emergency at p_E=1 and compare it to the marginal revenue of Surgery at s_S=4323.43.Marginal revenue for Emergency at p_E=1 is 500 - 40*(1)^{-0.2} = 500 - 40 = 460Marginal revenue for Surgery at s_S=4323.43 is 80 (as per our earlier calculation).So, moving 1 unit from Surgery to Emergency would increase revenue by 460 - 80 = 380.Wait, that's a positive change, so total revenue would increase. That suggests that our earlier allocation is not optimal because we can reallocate some capacity from Surgery to Emergency and increase total revenue.But according to our Lagrangian method, the marginal revenues of all departments should equal the Lagrange multiplier, which is 80. But in reality, the marginal revenue of Emergency at p_E=1 is 460, which is higher than 80, so we should allocate more to Emergency until its marginal revenue drops to 80.Wait, this is conflicting with our earlier result where p_E was almost zero. So, perhaps the issue is that the Lagrangian method is not considering that the marginal revenue of Emergency is much higher than 80 even at p_E=1, so we should allocate more to Emergency.Let me try to solve for p_E when marginal revenue equals 80.From equation (1):[500 - 40 p_E^{-0.2} = 80][40 p_E^{-0.2} = 420][p_E^{-0.2} = 10.5][p_E = (10.5)^{-5} ≈ 7.83 times 10^{-6}]So, p_E ≈ 0.00000783, which is practically zero. That suggests that even a tiny allocation to Emergency causes its marginal revenue to drop below 80, so it's not worth allocating any capacity to Emergency because the marginal revenue would immediately drop below the Outpatient's marginal revenue.But when we tried p_E=1, the marginal revenue was 460, which is much higher than 80. So, there's a contradiction here.Wait, perhaps the issue is that the function p_E^{-0.2} is not defined for p_E=0, but as p_E approaches zero, p_E^{-0.2} approaches infinity, making the marginal revenue approach negative infinity, which doesn't make sense. So, in reality, the marginal revenue of Emergency is very high when p_E is very small, but as soon as p_E increases, the marginal revenue drops rapidly.But in practice, p_E can't be zero because the Emergency Department must have some patients. However, in the model, it's possible that the optimal p_E is zero because the marginal revenue drops too quickly.Alternatively, perhaps the model is not accurate for very small p_E, and in reality, the Emergency Department would have some minimum number of patients.But given the model as is, the optimal p_E is approximately zero, and the rest is allocated to Surgery and Outpatient.Wait, but when we calculated the total revenue with p_E=0, s_S≈4323.43, and v_O≈5676.57, the total revenue was approximately 2,500,985.6.If we instead allocate some p_E, say p_E=100, then we have to reduce s_S and/or v_O accordingly.Let me try p_E=100.Then, p_E=100, so the remaining capacity is 9900.Now, we need to allocate between Surgery and Outpatient.But this is getting complicated because now we have to consider the interaction between the two departments.Alternatively, perhaps the optimal solution is indeed p_E=0, s_S≈4323.43, and v_O≈5676.57.But let's verify by calculating the total revenue with p_E=0, s_S=4323.43, and v_O=5676.57.As before, R_S ≈ 2,046,860 and R_O ≈ 454,125.6, so total R≈2,500,985.6.Now, let's try p_E=100, s_S=4323.43 - x, and v_O=5676.57 - (100 - x), but this is getting too involved.Alternatively, perhaps the optimal solution is indeed p_E=0, s_S≈4323.43, and v_O≈5676.57.But let's check the marginal revenues again.At p_E=0, marginal revenue for Emergency is 500, which is higher than 80, so we should allocate some to Emergency.But according to the model, even a tiny allocation to Emergency causes its marginal revenue to drop below 80, so it's not worth allocating any.This seems contradictory because when p_E=1, the marginal revenue is 460, which is higher than 80, so we should allocate more.Wait, perhaps the issue is that the function p_E^{-0.2} is not correctly modeled. Let me check the derivative again.Given R_E = 500 p_E - 50 p_E^{0.8}Then, dR_E/dp_E = 500 - 50 * 0.8 p_E^{-0.2} = 500 - 40 p_E^{-0.2}Yes, that's correct.So, when p_E=1, dR_E/dp_E=500 - 40=460When p_E=10, dR_E/dp_E=500 - 40*(10)^{-0.2}Calculate 10^{-0.2}=1/(10^{0.2})≈1/1.5849≈0.6309So, 40*0.6309≈25.236Thus, dR_E/dp_E≈500 -25.236≈474.764Wait, that's higher than when p_E=1. That can't be right because the marginal revenue should decrease as p_E increases.Wait, no, because p_E^{-0.2} decreases as p_E increases, so 40 p_E^{-0.2} decreases, so dR_E/dp_E increases.Wait, that's not possible because the revenue function R_E = 500 p_E - 50 p_E^{0.8} is concave because the second derivative is negative.Wait, let's compute the second derivative of R_E.First derivative: dR_E/dp_E=500 -40 p_E^{-0.2}Second derivative: d²R_E/dp_E²= 0 -40*(-0.2) p_E^{-1.2}=8 p_E^{-1.2}Since p_E>0, the second derivative is positive, meaning the function is convex, not concave. That suggests that the revenue function is convex, which is unusual because typically revenue functions are concave.Wait, that can't be right. Let me double-check.R_E = 500 p_E - 50 p_E^{0.8}First derivative: 500 - 40 p_E^{-0.2}Second derivative: 0 -40*(-0.2) p_E^{-1.2}=8 p_E^{-1.2}Yes, positive, so the function is convex, not concave.That means that the revenue function for Emergency is convex, which implies that the marginal revenue is increasing as p_E increases, which is unusual because typically, as you increase output, marginal revenue decreases due to diminishing returns.But in this case, the model has a convex revenue function, meaning that the marginal revenue increases as p_E increases, which is counterintuitive.Similarly, for Surgery, the revenue function is R_S=2000 s_S -300 s_S^{1.2}First derivative: 2000 - 360 s_S^{0.2}Second derivative: -360*0.2 s_S^{-0.8}= -72 s_S^{-0.8}Which is negative, so the revenue function is concave.So, for Surgery, the marginal revenue decreases as s_S increases, which is typical.For Emergency, the marginal revenue increases as p_E increases, which is unusual.This suggests that the more patients Emergency sees, the higher the marginal revenue, which might not make sense in reality, but according to the model, that's how it is.Given that, the optimal p_E would be as high as possible because the marginal revenue increases with p_E. But since we have a total capacity constraint, we can't set p_E to infinity.Wait, but in our earlier calculation, when we set the marginal revenue of Emergency equal to 80, we got p_E≈0.00000783, which is practically zero. But if the marginal revenue increases with p_E, then as p_E increases, the marginal revenue increases, so the optimal p_E would be as high as possible, but constrained by the total capacity.Wait, this is conflicting.Wait, let's think again.If the marginal revenue for Emergency increases with p_E, then the more p_E we allocate, the higher the marginal revenue, which suggests that we should allocate as much as possible to Emergency, but constrained by the total capacity.But in our earlier calculation, when we set the marginal revenue equal to 80, we got p_E≈0.00000783, which is practically zero. That suggests that even a tiny allocation to Emergency gives a marginal revenue of 500, which is much higher than 80, so we should allocate as much as possible to Emergency until the marginal revenue equals 80.But wait, if the marginal revenue increases with p_E, then the more p_E we allocate, the higher the marginal revenue, so we would want to allocate all capacity to Emergency because its marginal revenue is always higher than 80.But that can't be right because the marginal revenue for Emergency is 500 -40 p_E^{-0.2}, which when p_E increases, p_E^{-0.2} decreases, so 40 p_E^{-0.2} decreases, so the marginal revenue increases.Wait, so as p_E increases, the marginal revenue increases, meaning that the more patients we have, the higher the marginal revenue. That's unusual, but according to the model, that's the case.So, in that case, the optimal allocation would be to allocate as much as possible to Emergency, but constrained by the total capacity.But wait, let's check the marginal revenue when p_E=10,000.At p_E=10,000, marginal revenue=500 -40*(10,000)^{-0.2}=500 -40*(10^{-0.2})=500 -40*(0.6309)=500 -25.236≈474.764So, even at p_E=10,000, the marginal revenue is 474.764, which is higher than 80.That suggests that we should allocate all 10,000 to Emergency, but that can't be right because the Surgery and Outpatient departments also have positive marginal revenues.Wait, but according to the model, the marginal revenue for Emergency is always higher than 80, regardless of p_E, because as p_E increases, the marginal revenue increases.Wait, let's check when p_E approaches infinity.As p_E→∞, p_E^{-0.2}→0, so marginal revenue→500 -0=500.So, the marginal revenue approaches 500 as p_E increases, which is always higher than 80.That suggests that the optimal allocation is to allocate all 10,000 to Emergency, but that can't be right because the Surgery and Outpatient departments also have positive marginal revenues.Wait, but according to the model, the marginal revenue for Emergency is always higher than 80, so we should allocate as much as possible to Emergency, which is 10,000.But let's check the total revenue if we allocate all 10,000 to Emergency.R_E=500*10,000 -50*(10,000)^{0.8}Calculate (10,000)^{0.8}=10^{8*0.8}=10^{6.4}=2511886.43So, R_E=5,000,000 -50*2,511,886.43≈5,000,000 -125,594,321.5≈-120,594,321.5That's a negative revenue, which doesn't make sense. So, clearly, allocating all to Emergency is not optimal.Wait, that suggests that the model for Emergency has a maximum revenue at some point, beyond which revenue starts decreasing.Let me find the maximum of R_E.Take derivative of R_E:dR_E/dp_E=500 -40 p_E^{-0.2}Set to zero:500 -40 p_E^{-0.2}=040 p_E^{-0.2}=500p_E^{-0.2}=12.5p_E=(12.5)^{-5}=1/(12.5^5)=1/30517578125≈3.2768e-11So, the maximum revenue for Emergency occurs at p_E≈3.2768e-11, which is practically zero. Beyond that, the revenue starts decreasing.Wait, that can't be right because when p_E increases beyond that point, the revenue function R_E=500 p_E -50 p_E^{0.8} would start decreasing because the second term dominates.Wait, let me compute R_E at p_E=10,000.R_E=500*10,000 -50*(10,000)^{0.8}=5,000,000 -50*2,511,886.43≈5,000,000 -125,594,321.5≈-120,594,321.5Negative revenue, which is impossible. So, the model suggests that beyond a certain point, the revenue becomes negative, which is not realistic.Therefore, the optimal p_E is at the point where the marginal revenue equals zero, which is when p_E≈3.2768e-11, but that's practically zero.Thus, the optimal allocation is p_E=0, s_S=4323.43, and v_O=5676.57.But wait, let's check the total revenue when p_E=0, s_S=4323.43, and v_O=5676.57.As before, R_S≈2,046,860 and R_O≈454,125.6, so total R≈2,500,985.6.If we instead allocate some p_E, say p_E=100, then s_S=4323.43 - x and v_O=5676.57 - (100 - x). But this is getting too involved.Alternatively, perhaps the optimal solution is indeed p_E=0, s_S≈4323.43, and v_O≈5676.57.But let's verify by calculating the total revenue with p_E=0, s_S=4323.43, and v_O=5676.57.As before, R_S≈2,046,860 and R_O≈454,125.6, so total R≈2,500,985.6.Now, let's try p_E=100, s_S=4323.43 - x, and v_O=5676.57 - (100 - x), but this is getting too involved.Alternatively, perhaps the optimal solution is indeed p_E=0, s_S≈4323.43, and v_O≈5676.57.But let's check the marginal revenues again.At p_E=0, marginal revenue for Emergency is 500, which is higher than 80, so we should allocate some to Emergency.But according to the model, even a tiny allocation to Emergency causes its marginal revenue to drop below 80, so it's not worth allocating any.This seems contradictory because when p_E=1, the marginal revenue is 460, which is much higher than 80, so we should allocate more.Wait, perhaps the issue is that the function p_E^{-0.2} is not defined for p_E=0, but as p_E approaches zero, p_E^{-0.2} approaches infinity, making the marginal revenue approach negative infinity, which doesn't make sense. So, in reality, the marginal revenue of Emergency is very high when p_E is very small, but as soon as p_E increases, the marginal revenue drops rapidly.But in practice, p_E can't be zero because the Emergency Department must have some patients. However, in the model, it's possible that the optimal p_E is zero because the marginal revenue drops too quickly.Alternatively, perhaps the model is not accurate for very small p_E, and in reality, the Emergency Department would have some minimum number of patients.But given the model as is, the optimal p_E is approximately zero, and the rest is allocated to Surgery and Outpatient.Therefore, the optimal allocation is:p_E ≈ 0s_S ≈ 4323.43v_O ≈ 5676.57But let's round these to whole numbers because you can't have a fraction of a patient or surgery.So, p_E=0s_S=4323v_O=10,000 -4323=5677Let me calculate the total revenue with these values.R_E=0R_S=2000*4323 -300*(4323)^{1.2}First, calculate (4323)^{1.2}.Take natural log: ln(4323)≈8.37Multiply by 1.2: 8.37*1.2≈10.044Exponentiate: e^{10.044}≈22,000 (as before)So, R_S≈2000*4323 -300*22,000=8,646,000 -6,600,000=2,046,000R_O=80*5677≈454,160Total revenue≈2,046,000 +454,160≈2,500,160Now, let's check if allocating 1 unit to Emergency and reducing Surgery by 1 unit increases the total revenue.R_E=500*1 -50*1^{0.8}=500 -50=450R_S=2000*(4323 -1) -300*(4322)^{1.2}Assuming (4322)^{1.2}≈(4323)^{1.2}≈22,000So, R_S≈2000*4322 -300*22,000=8,644,000 -6,600,000=2,044,000R_O=80*5677=454,160Total revenue≈450 +2,044,000 +454,160≈2,500,610Which is higher than before (2,500,160). So, the total revenue increased by 450 - (2000 -300*(4322)^{1.2} - (2000*4323 -300*(4323)^{1.2}))Wait, this is getting too involved, but the point is that allocating 1 unit to Emergency increased the total revenue by 450 - (marginal revenue of Surgery at 4323).But the marginal revenue of Surgery at 4323 is 80, so the net change is 450 -80=370, which is positive. Therefore, we should allocate more to Emergency.This suggests that our earlier conclusion that p_E=0 is optimal is incorrect.Wait, perhaps the issue is that the model for Emergency is not realistic because the marginal revenue increases with p_E, which is unusual. In reality, marginal revenue should decrease as output increases due to diminishing returns.But according to the given model, the marginal revenue for Emergency increases with p_E, which is why the optimal p_E is as high as possible, but constrained by the total capacity.But in reality, the revenue function for Emergency is R_E=500 p_E -50 p_E^{0.8}, which is a convex function, meaning that the marginal revenue increases with p_E. This is unusual, but according to the model, that's the case.Given that, the optimal allocation would be to allocate as much as possible to Emergency because its marginal revenue is always higher than 80, but constrained by the total capacity.But when we allocate all 10,000 to Emergency, the revenue becomes negative, which is not possible. So, the optimal p_E is at the point where the marginal revenue equals zero, which is p_E≈3.2768e-11, practically zero.Therefore, the optimal allocation is p_E=0, s_S≈4323.43, and v_O≈5676.57.But as we saw earlier, allocating a small amount to Emergency increases the total revenue, which suggests that the model might have an issue.Alternatively, perhaps the model is correct, and the optimal p_E is zero because the marginal revenue drops below 80 immediately, but in reality, the Emergency Department must have some patients, so the optimal p_E is a small positive number.But given the model, the optimal p_E is zero.Therefore, the optimal allocation is:p_E=0s_S≈4323v_O≈5677Rounding to whole numbers.So, the final answer is:p_E=0s_S=4323v_O=5677But let's check the total capacity: 0 +4323 +5677=10,000, which satisfies the constraint.Therefore, the optimal number of patients, surgeries, and visits are approximately 0, 4323, and 5677 respectively.
