The limit of f(x) as x approaches positive infinity is +∞, and the limit as x approaches negative infinity is -∞. This indicates that the function f(x) becomes arbitrarily large (positive or negative) as x moves towards infinity or negative infinity.

To find the limits of the function f(x) = (9x + 2) as x approaches positive infinity and negative infinity, we evaluate the function for very large and very small values of x.

As x approaches positive infinity (x → +∞), the value of 9x dominates the function, and the constant term 2 becomes negligible in comparison. Therefore, we can approximate the limit as:

lim(x → +∞) f(x) = lim(x → +∞) (9x + 2) = +∞

This means that as x approaches positive infinity, the function f(x) grows without bound.

On the other hand, as x approaches negative infinity (x → -∞), the value of 9x becomes very large in the negative direction, making the constant term 2 insignificant. Therefore, we can approximate the limit as:

lim(x → -∞) f(x) = lim(x → -∞) (9x + 2) = -∞

This means that as x approaches negative infinity, the function f(x) also grows without bound, but in the negative direction.

(a). The curl of F is given by curl F = (4e^7z) i - 4 j - 4x^3 k.

(b). The work done by the vector field F along the closed curve of the circle is zero.

To find the curl of the vector field

[tex]F = (42 + 4x^4) i + (4y + 62 + 6sin(y)) j + (4x + 6y + 4e^{7z})[/tex]k, we'll compute the curl as follows:

(a) Curl F:

The curl of a vector field F = P i + Q j + R k is given by the following determinant:

curl F = (∂R/∂y - ∂Q/∂z) i + (∂P/∂z - ∂R/∂x) j + (∂Q/∂x - ∂P/∂y) k

Let's compute the partial derivatives:

∂P/∂x = [tex]16x^3[/tex]

∂Q/∂y = 4

∂R/∂z = [tex]4e^{7z[/tex]

∂Q/∂z = 0 (as there is no z term in Q)

∂R/∂x = 4

∂P/∂y = 0 (as there is no y term in P)

Now, we can calculate the components of the curl:

curl F =[tex](4e^{7z} - 0) i + (0 - 4) j + (0 - 4x^3) k[/tex]

   = [tex](4e^{7z}) i - 4 j - 4x^3 k[/tex]

(b) Regarding the line integral ∮ F · dr, where r is the circle

[tex](x - 3)^2 + (y - 5)^2 = 25[/tex] :

Since the curl of F is zero (curl F = 0), it implies that F is a conservative vector field. This means that the line integral ∮ F · dr around any closed curve will be zero.

For the circle given by [tex](x - 3)^2 + (y - 5)^2 = 25[/tex], it is a closed curve. Therefore, we can conclude that the line integral ∮ F · dr around this circle is zero.

To find the absolute maximum and minimum of the function f(x) = x^2 + 4x - 5 on the interval (-1, 2], we need to evaluate the function at critical points and endpoints within the given interval.

Step 1: Find the critical points by taking the derivative of f(x) and setting it equal to zero.

f'(x) = 2x + 4

Setting f'(x) = 0, we get:

2x + 4 = 0

x = -2

Step 2: Evaluate the function at the critical points and endpoints.

f(-1) = (-1)^2 + 4(-1) - 5 = -2

f(2) = (2)^2 + 4(2) - 5 = 9

f(-2) = (-2)^2 + 4(-2) - 5 = -9

Step 3: Compare the values obtained to determine the absolute maximum and minimum.

The absolute maximum value is 9, which occurs at x = 2.

The absolute minimum value is -9, which occurs at x = -2.

To convert p = 9 cos θ from spherical to cylindrical coordinates, The cylindrical coordinates of the point are (9 cos θ, 0, 0) for all values of θ, and the point lies on the sphere with equation 22 + p2 - 92 = 0. The correct option of this question is C.

We have to first identify the spherical coordinates and then apply the formulas for converting them to cylindrical coordinates.

The spherical coordinates are (p, θ, φ),

where p is the distance from the origin, θ is the angle from the positive x-axis to the projection of the point onto the xy-plane, and φ is the angle from the positive z-axis to the point.

In this case, we have p = 9 cos θ and φ = π/2 (since the point is in the xy-plane).

Therefore, the spherical coordinates are (9 cos θ, θ, π/2).
To convert these coordinates to cylindrical coordinates (ρ, φ, z),

we use the formulas ρ = p sin φ, z = p cos φ, and tan φ = z/ρ.

Since φ = π/2, we have sin φ = 1 and cos φ = 0.

Therefore, ρ = p sin φ = 9 cos θ sin π/2 = 9 cos θ, and z = p cos φ = 9 cos θ cos π/2 = 0.

Thus, the cylindrical coordinates are (9 cos θ, φ, 0).
The answer (d) is 22 + p2 - 92 = 0.

This is the equation of a sphere centered at (0, 9, 0) with radius √22.

To see this, note that the equation can be written as p2 - 92 = 22 - z2, which is the equation of a sphere centered at (0, 9, 0) with a radius √22.

Therefore, the cylindrical coordinates of the point are (9 cos θ, 0, 0) for all values of θ, and the point lies on the sphere with equation 22 + p2 - 92 = 0.

The solution to the initial value problem is given by:$$-2\ln|y+1|+3\ln|3y+5| = x + \ln\frac{8}{15}$$

The given differential equation is:

$\frac{dy}{dx}=\frac{3y+5}{5-x²}$.

The initial condition is given as:

$y=-1$ when $x=0$.

First, separate the variables as shown below:

$\frac{5-x²}{3y+5}dy=dx$

Now integrate both sides of the equation:

$\int\frac{5-x²}{3y+5}dy=\int dx$

We can now integrate the left-hand side using partial fractions.

We write the expression as:

$$\frac{5-x²}{3y+5}

= \frac{A}{y+1} + \frac{B}{3y+5}$$

We can then equate the numerators:$$5 - x²

= A(3y + 5) + B(y + 1)$$

Substitute $y = -1$ and $x = 0$ into the equation above to get $A = -2$.

Now substitute $y = 0$ and $x = 1$ to get $B = 3$.

Therefore, we have:$$\frac{5-x²}{3y+5} = \frac{-2}{y+1} + \frac{3}{3y+5}$$

Now, substituting this into the original equation,

we get:$$\int\frac{-2}{y+1}+\frac{3}{3y+5}dy=\int dx$$

Integrating both sides of the equation:

$$-2\ln|y+1|+3\ln|3y+5| = x+C$$

Substitute the initial value $y = -1$ and $x = 0$ into the equation above to get $C = \ln(8/15)$.

The divergence of a vector field F = <P, Q, R> in three-dimensional space (R³) is defined as the scalar function that represents the rate at which the field "spreads out" or "diverges" from a given point.

The divergence of a vector field F = <P, Q, R> is denoted by ∇ · F, where ∇ (del) represents the gradient operator. The divergence is a scalar function that calculates the change in the flux of the vector field across an infinitesimally small volume around a point. It measures how the vector field expands or contracts at each point in space.

Mathematically, the divergence of F is given by the sum of the partial derivatives of its components with respect to their corresponding variables: ∇ · F = (∂P/∂x) + (∂Q/∂y) + (∂R/∂z). Geometrically, the divergence represents the density of the field's source or sink at a particular point. Positive divergence indicates an outward flow, while negative divergence implies an inward flow.

The divergence theorem, also known as Gauss's theorem, establishes a relationship between the divergence and the flux of a vector field through a closed surface. It states that the flux of a vector field across a closed surface is equal to the volume integral of the field's divergence over the region enclosed by the surface.

In summary, the divergence of a vector field in three-dimensional space provides information about the rate at which the field diverges or converges at each point. It is a scalar function obtained by summing the partial derivatives of the field's components. The divergence theorem relates the divergence to the flux of the vector field through a closed surface.

There does not exist any elliptic curve over Z7 with exactly 13 points (including [infinity]). In other words, the answer is negative.

An elliptic curve with exactly 13 points (including [infinity]) cannot exist over Z7.

It is known that for an elliptic curve over a field F, the number of points on the curve is congruent to 1 modulo 6 if the field characteristic is not 2 or 3.

If the field characteristic is 2 or 3, then the number of points is not congruent to 1 modulo 6. This is known as the Hasse bound.

Using this fact, we can easily prove that no elliptic curve over Z7 can have exactly 13 points.

The number 13 is not congruent to 1 modulo 6, so there cannot exist an elliptic curve over Z7 with exactly 13 points (including [infinity]).

Therefore, there does not exist any elliptic curve over Z7 with exactly 13 points (including [infinity]). In other words, the answer is negative.

Given that rectangles H and K are similar, and we have the dimensions of rectangle H , The area of rectangle K is approximately 225 square centimeters.

Let's denote the dimensions of rectangle K as Lk and Wk, representing its length and width, respectively.

Using the concept of similarity, we know that corresponding sides of similar rectangles are proportional. In this case, the ratio of the width of rectangle K (Wk) to the width of rectangle H (Wh) is equal to the ratio of the length of rectangle K (Lk) to the length of rectangle H (Lh).

We can set up the following proportion:

Wk / Wh = Lk / Lh

Substituting the given values:

Wk / 5cm = Lk / 8cm

Now, we can use the information provided to find the dimensions of rectangle K. It is given that the width of rectangle H is 5cm and the width of rectangle H is 15cm.

Solving for Wk in the proportion:

Wk / 5cm = 15cm / 8cm

Cross-multiplying and simplifying:

8Wk = 75cm

Wk = 75cm / 8

Wk ≈ 9.375cm

Now that we have the width of rectangle K, we can find the length using the same proportion:

Lk / 8cm = 15cm / 5cm

Cross-multiplying and simplifying:

5Lk = 8 * 15

Lk = 8 * 15 / 5

Lk = 24cm

Finally, we can calculate the area of rectangle K using the formula: Area = Length * Width.

Area of K = Lk * Wk

Area of K = 24cm * 9.375cm

Area of K ≈ 225 cm²

In the timid strategy, Smith bets 1 dollar each time. The probability of winning a bet is 0.4, and the probability of losing is 0.6. We can calculate the probability that Smith wins 8 dollars before losing all his money using a binomial distribution. The formula for the probability is P(X = k) =[tex]\binom{n}{k} \cdot p^k \cdot q^{n-k}[/tex], where n is the number of trials, k is the number of successes, p is the probability of success, and q is the probability of failure. In this case, n = 8, k = 8, p = 0.4, and q = 0.6. By substituting these values into the formula, we can calculate the probability to be approximately 0.214.

(b) The probability that Smith wins 8 dollars before losing all his money using the bold strategy is approximately 0.649.

In the bold strategy, Smith bets as much as possible but not more than necessary to reach 8 dollars. This means he bets 1 dollar until he has 7 dollars, and then he bets the remaining amount to reach 8 dollars. We can calculate the probability using the same binomial distribution formula, but with different values for n and k. In this case, n = 7, k = 7, p = 0.4, and q = 0.6. By substituting these values into the formula, we can calculate the probability.

P(X = 7) =[tex]\binom{7}{7} \cdot 0.4^7 \cdot 0.6^{7-7} \approx 0.014[/tex] ≈ 0.014

P(X = 8) =[tex]\binom{8}{8} \cdot 0.4^8 \cdot 0.6^{8-8} \approx 0.635[/tex] ≈ 0.635

Total probability = P(X = 7) + P(X = 8) ≈ 0.649

Ava and Kelly will be 3/4 mile apart after 22.5 minutes.

To determine when Ava and Kelly will be 3/4 mile apart, we can consider their relative speed. The relative speed is the difference between their individual speeds.

Ava's speed = 6 miles per hour

Kelly's speed = 8 miles per hour

The relative speed of Ava and Kelly is:

Relative speed = Kelly's speed - Ava's speed

= 8 miles per hour - 6 miles per hour

= 2 miles per hour

This means that Ava and Kelly are moving away from each other at a rate of 2 miles per hour.

To calculate the time it takes for them to be 3/4 mile apart, we can use the formula:

Distance = Speed × Time

In this case, the distance they need to cover is 3/4 mile, and the relative speed is 2 miles per hour.

3/4 mile = 2 miles per hour × Time

Simplifying the equation:

3/4 = 2 × Time

Dividing both sides by 2:

3/4 × 1/2 = Time

3/8 = Time

Therefore, it will take Ava and Kelly 3/8 hours (or 22.5 minutes) to be 3/4 mile apart.

The absolute maximum value of f(x) = x^3e^x on (-1, 1] is e, and the absolute minimum value is -e^(-1).

To find the absolute maximum and minimum values of the function f(x) = x^3e^x on the interval (-1, 1], we need to evaluate the function at its critical points and endpoints within the interval. Critical Points: To find the critical points, we take the derivative of the function and set it equal to zero:

f'(x) = 3x^2e^x + x^3e^x = 0. Factoring out e^x, we have: e^x(3x^2 + x^3) = 0

This equation is satisfied when either e^x = 0 (which has no solution) or 3x^2 + x^3 = 0. Solving 3x^2 + x^3 = 0, we find the critical points: x = 0 (double root) x = -3. Endpoints: The endpoints of the interval (-1, 1] are -1 and 1. Now, we evaluate the function at these critical points and endpoints to find the corresponding function values: f(-1) = (-1)^3e^(-1) = -e^(-1). f(0) = (0)^3e^(0) = 0, f(1) = (1)^3e^(1) = e

Comparing these function values, we can determine the absolute maximum and minimum: Absolute Maximum: The function reaches a maximum of e at x = 1. Absolute Minimum: The function reaches a minimum of -e^(-1) at x = -1. Therefore, the absolute maximum value of f(x) = x^3e^x on (-1, 1] is e, and the absolute minimum value is -e^(-1).

At the point (4, 5π/6), we have r = 8 sin (5π/6) = 8(1/2) = 4, and θ = 5π/6.

Therefore, the slope of the tangent line at the point (4, 5π/6) is given by the derivative dr/dθ For the polar curve r = 8 sin θ, we need to find the slope of the tangent line at the point (4, 5π/6).

Using the same process, we find that the derivative of r with respect to θ is dr/dθ = r' = d/dθ (8 sin θ) = 8 cos θ.

At the point (4, 5π/6), we have r = 8 sin (5π/6) = 8(1/2) = 4, and θ = 5π/6.

14 = 0 - 3 + 2πC₁ + 3

2πC₁ = 14 - 0

2πC₁ = 14

C₁ = 7/π

Now we have the specific values for the constants C₁ and C₂, and we can write the position function s(t) as:

s(t) = -13 sin(t) - 3 cos(t) + (7/π)t + 3

Thus, the position of the particle at any given time t is given by the equation:

s(t) = -13 sin(t) - 3 cos(t) + (7/π)t + 3

The solution to the differential equation [tex]y^2y'' = y'[/tex] is [tex]y = (3ux + 3C)^{(1/3)[/tex], where u = y' and C is the constant of integration.

An equation involving one or more functions and their derivatives is referred to as a differential equation. The rate of change of a function at a place is determined by the derivatives of the function.

To solve the given differential equation [tex]y^2y'' = y'[/tex], we can use the substitution u = y'. Taking the derivative of u with respect to x, we have du/dx = y''.

Using this substitution, the differential equation can be rewritten as [tex]y^2(du/dx) = u[/tex].

Now, we have a separable differential equation. We can rearrange the terms as follows:

[tex]y^2 dy = u dx[/tex]

We can integrate both sides of the equation:

∫ [tex]y^2 dy = ∫ u dx[/tex].

Integrating, we get:

[tex](1/3) y^3 = ux + C[/tex],

where C is the constant of integration.

Now, we can solve for y by isolating y on one side:

[tex]y^3 = 3ux + 3C[/tex].

Taking the cube root of both sides:

[tex]y = (3ux + 3C)^{(1/3)[/tex].

Therefore, the solution to the differential equation [tex]y^2y'' = y'[/tex] is [tex]y = (3ux + 3C)^{(1/3)[/tex], where u = y' and C is the constant of integration.

Given that sin θ = 4/5 and θ is in quadrant 2, we can determine the values of the remaining trigonometric functions of θ.

Using the Pythagorean identity, sin^2 θ + cos^2 θ = 1, we can find the value of cos θ:

cos^2 θ = 1 - sin^2 θ

cos^2 θ = 1 - (4/5)^2

cos^2 θ = 1 - 16/25

cos^2 θ = 9/25

cos θ = ±√(9/25)

cos θ = ±3/5

Since θ is in quadrant 2, the cosine value is negative. Therefore, cos θ = -3/5.

Using the equation tan θ = sin θ / cos θ, we can find the value of tan θ:

tan θ = (4/5) / (-3/5)

tan θ = -4/3

The remaining trigonometric functions are:

cosec θ = 1/sin θ = 1/(4/5) = 5/4

sec θ = 1/cos θ = 1/(-3/5) = -5/3

cot θ = 1/tan θ = 1/(-4/3) = -3/4

Therefore, the exact values of the remaining trigonometric functions are:

cos θ = -3/5, tan θ = -4/3, cosec θ = 5/4, sec θ = -5/3, cot θ = -3/4.

T2(2) = 2 and T3(2) = 2.

To calculate the Taylor polynomials, we first need to find the derivatives of the function f(x) = tan(x) at the center x = 0.

The derivatives of tan(x) are:

f'(x) = [tex]sec^2(x)[/tex]

f''(x) = [tex]2sec^2(x)tan(x)[/tex]

f'''(x) = [tex]2sec^2(x)tan^2(x) + 2sec^4(x)[/tex]

Now let's calculate the Taylor polynomials centered at x = 0:

T2(x):

Using the derivatives, we can find the coefficients of the Taylor polynomial as follows:

T2(x) =[tex]f(0) + f'(0)(x - 0) + \frac{f''(0)(x - 0)^2}{2!}[/tex]

Since f(0) = tan(0) = 0, and f'(0) = [tex]sec^2(0)[/tex] = 1, and f''(0) = [tex]2sec^2(0)tan(0)[/tex] = 0, the Taylor polynomial T2(x) simplifies to:

T2(x) = [tex]0 + 1(x - 0) + \frac{ 0(x - 0)^2}{2!}[/tex]= x

Therefore, T2(x) = x.

T3(x):

Using the derivatives, we can find the coefficients of the Taylor polynomial as follows:

T3(x) =[tex]f(0) + f'(0)(x - 0) + \frac{f''(0)(x - 0)^2}{2!} + \frac{f'''(0)(x - 0)^3}{3!}[/tex]

Since f(0) = 0, f'(0) = 1, f''(0) = 0, and f'''(0) = 0, the Taylor polynomial T3(x) simplifies to:

T3(x) = [tex]0 + 1(x - 0) + \frac{0(x - 0)^2}{2!} + \frac{0(x - 0)^3}{3!}[/tex]

         = x

Therefore, T3(x) = x.

Thus, T2(2) = 2 and T3(2) = 2.

a)The degree of the numerator is greater than the degree of the denominator, the curve does not have a horizontal asymptote.

b)  Both the left-hand and right-hand limits are equal to -3/2, we conclude that x = -3 is a vertical asymptote when n = 1 for the given curve.

To determine if the curve y = (3x^2 + 2)/(8x + 24) has a horizontal asymptote, we need to examine the behavior of the function as x approaches positive or negative infinity.

(a) For the function to have a horizontal asymptote, the degree of the numerator (3x^2 + 2) should be less than or equal to the degree of the denominator (8x + 24). Let's compare the degrees of the numerator and the denominator:

Degree of the numerator: 2

Degree of the denominator: 1

Since the degree of the numerator is greater than the degree of the denominator, the curve does not have a horizontal asymptote.

(b) To show that x = -3 is a vertical asymptote when n = 1, we need to evaluate the limit of the function as x approaches -3 from both the left and the right sides.

Let's find the limit as x approaches -3 from the left side:

lim(x->-3-) [(3x^2 + 2)/(8x + 24)]

Substituting -3 for x:

lim(x->-3-) [(3(-3)^2 + 2)/(8(-3) + 24)]

= lim(x->-3-) [(3(9) + 2)/(-24 + 24)]

= lim(x->-3-) [(27 + 2)/0]

Since the denominator approaches 0, we have an indeterminate form. To resolve this, we can simplify the function by factoring out common factors:

lim(x->-3-) [(3(x^2 - 1))/(8(x + 3))]

Now, cancel out the common factor of (x + 3):

lim(x->-3-) [(3(x - 1))/(8)]

Substituting -3 for x:

lim(x->-3-) [(3(-3 - 1))/(8)]

= lim(x->-3-) [(3(-4))/(8)]

= lim(x->-3-) [-12/8]

= -3/2

Now, let's find the limit as x approaches -3 from the right side:

lim(x->-3+) [(3x^2 + 2)/(8x + 24)]

Following similar steps as before, we simplify the function by factoring and canceling out the common factor:

lim(x->-3+) [(3(x^2 - 1))/(8(x + 3))]

Substituting -3 for x:

lim(x->-3+) [(3(-3 - 1))/(8)]

= lim(x->-3+) [(3(-4))/(8)]

= lim(x->-3+) [-12/8]

= -3/2

Since both the left-hand and right-hand limits are equal to -3/2, we conclude that x = -3 is a vertical asymptote when n = 1 for the given curve.

To estimate the area under the graph of the function f(x) = 2x - 3x + 4 from x = -1 to x = 1, we can use the method of approximating rectangles.

(A) Using 4 Approximating Rectangles with Right Endpoints:

To begin, we divide the interval from -1 to 1 into 4 equal subintervals. The width of each subinterval is (1 - (-1))/4 = 2/4 = 1/2.

The right endpoints for the 4 subintervals are: -1/2, 0, 1/2, 1.

Now, we calculate the function values at these right endpoints:

Next, we multiply each function value by the width of the subinterval (1/2) to get the area of each rectangle:

Area of first rectangle = (1/2) * (13/2) = 13/4

Area of second rectangle = (1/2) * (4) = 2

Area of third rectangle = (1/2) * (11/2) = 11/4

Area of fourth rectangle = (1/2) * (3) = 3/2

Finally, we sum up the areas of the rectangles to estimate the total area:

Estimated Area = (13/4) + 2 + (11/4) + (3/2) = 19/4 = 4.75

(B) Using 8 Approximating Rectangles with Right Endpoints:

To begin, we divide the interval from -1 to 1 into 8 equal subintervals. The width of each subinterval is (1 - (-1))/8 = 2/8 = 1/4.

For each subinterval, we evaluate the function at the right endpoint and multiply it by the width of the subinterval to get the area of the rectangle.

The right endpoints for the 8 subintervals are: -3/4, -1/2, -1/4, 0, 1/4, 1/2, 3/4, 1.

Now, we calculate the function values at these right endpoints.

Next, we multiply each function value by the width of the subinterval (1/4) to get the area of each rectangle:

Area of first rectangle = (1/4) * (23/4) = 23/16

Area of second rectangle = (1/4) * (11/2) = 11/8

Area of third rectangle = (1/4) * (17/4) = 17/16

Area of fourth rectangle = (1/4) * (4) = 1

Area of fifth rectangle = (1/4) * (15/4) = 15/16

Area of sixth rectangle = (1/4) * (9/2) = 9/8

Area of seventh rectangle = (1/4) * (17/4) = 17/16

Area of eighth rectangle = (1/4) * (3) = 3/4

Finally, we sum up the areas of the rectangles to estimate the total area:

Estimated Area = (23/16) + (11/8) + (17/16) + 1 + (15/16) + (9/8) + (17/16) + (3/4) = 91/8 = 11.375

The given system of equations does not have a solution as there are no values of a, b, and c that allow the given system of equations to have a solution.

To determine the values of the constants a, b, and c that allow the given system of equations to have a solution, we need to examine the system and check for consistency and dependence.

The system of equations is as follows:

x + 2y + z = a

-y + z = -2a

2 + 3y + 2z = b

3r - y + z = c

To find the values of a, b, and c that satisfy the system, we can perform operations on the equations to simplify and compare them.

Starting with equation 2, we can rewrite it as y - z = 2a.

Comparing equation 1 and equation 3, we notice that the coefficients of y and z are different.

In order for the system to have a solution, the coefficients of y and z in both equations should be proportional.

Therefore, we need to find values of a, b, and c such that the ratios between the coefficients in equation 1 and equation 3 are equal.

From equation 1, the ratio of the coefficient of y to the coefficient of z is 2.

From equation 3, the ratio of the coefficient of y to the coefficient of z is 3/2. Setting these ratios equal, we have:

2 = 3/2

4 = 3

Since the ratio is not equal, there are no values of a, b, and c that satisfy the system of equations.

Therefore, the system does not have a solution.

In summary, there are no values of a, b, and c that allow the given system of equations to have a solution.

We have to find the maximum population density and specify where it occurs.To find the maximum population density, we have to find the coordinates of the maximum point.The general form of the quadratic equation is:

f(x,y) =[tex]ax^2 + by^2 + cx + dy + e[/tex].Here a = -20, b = -25, c = 480, d = 800 and e = 170

Differentiating P(x,y) w.r.t x, we get[tex]∂P(x,y)/∂x[/tex] = -40x + 480

Differentiating P(x,y) w.r.t y, we get [tex]∂P(x,y)/∂y[/tex] = -50y + 800

For the maximum value of P(x,y), we need [tex]∂P(x,y)/∂x[/tex] = 0 and [tex]∂P(x,y)/∂y[/tex] = 0-40x + 480 = 0 => x = 12-50y + 800 = 0 => y = 16
