The set S = {(-3, 4), (0, 0)} is not a basis for the vector space R.

To determine if S is a basis for R, we need to check if the vectors in S are linearly independent and if they span R.

First, we check for linear independence. If the only solution to the equation c1(-3, 4) + c2(0, 0) = (0, 0) is c1 = c2 = 0, then the vectors are linearly independent. However, in this case, we can see that c1 = c2 = 0 is not the only solution. We can choose c1 = 1 and c2 = 0, and the equation still holds true. Therefore, the vectors in S are linearly dependent.

Since the vectors in S are linearly dependent, they cannot span R. A basis for R must consist of linearly independent vectors that span the entire space. Therefore, S is not a basis for R.

The area of the given curve, y^2 = 8 - x is = ∫[0, 8] √(8 - x) dx.

To find the area bounded by this curve and both coordinate axes in the first quadrant, we need to integrate the curve from x = 0 to x = a, where a is the x-coordinate of the point where the curve intersects the x-axis.

Step 1: Finding the x-intercept

To find the x-coordinate of the point where the curve intersects the x-axis, we set y^2 = 8 - x to zero and solve for x:

0 = 8 - x

x = 8

So, the curve intersects the x-axis at the point (8, 0).

Step 2: Finding the area

The area bounded by the curve and both coordinate axes can be calculated by integrating the curve from x = 0 to x = 8.

Using the equation y^2 = 8 - x, we can rewrite it as y = √(8 - x). Since we are interested in the first quadrant, we consider the positive square root.

The area can be found by integrating the function y = √(8 - x) with respect to x from x = 0 to x = 8:

Area = ∫[0, 8] √(8 - x) dx

To evaluate this integral, we can use various integration techniques, such as substitution or integration by parts.

Once we evaluate the integral, we will have the value of the area bounded by the curve and both coordinate axes in the first quadrant.

In this solution, we first determine the x-coordinate of the point where the curve intersects the x-axis by setting y^2 = 8 - x to zero and solving for x. We then establish the limits of integration as x = 0 to x = 8.

By integrating the function y = √(8 - x) with respect to x within these limits, we calculate the area bounded by the curve and both coordinate axes in the first quadrant. The choice of integration technique may vary depending on the complexity of the function, but the result will provide the desired area.

The initial value problem is a first-order separable ordinary differential equation. To solve it, we can rewrite the equation and integrate both sides. The solution will involve finding the antiderivative of the function and applying the initial condition. The slope field is a graphical representation of the differential equation that shows the slopes of the solution curves at different points. By plotting small line segments with slopes at various points, we can sketch an approximate solution curve.

The initial value problem is given by Sy' = 3t^2y^2, with the initial condition y(0) = 1. To solve it, we first rewrite the equation as dy/y^2 = 3t^2 dt. Integrating both sides gives ∫(1/y^2)dy = ∫3t^2dt. The integral of 1/y^2 is -1/y, and the integral of 3t^2 is t^3. Applying the limits of integration and simplifying, we get -1/y = t^3 + C, where C is the constant of integration. Solving for y gives y = -1/(t^3 + C). Applying the initial condition y(0) = 1, we find C = -1, so the solution is y = -1/(t^3 - 1).

To sketch the slope field, we plot small line segments with slopes given by the differential equation at various points in the t-y plane. At each point (t, y), the slope is given by y' = 3t^2y^2. By drawing these line segments at different points, we can get an approximate visual representation of the solution curves. To illustrate the approximate solution curve satisfying y(0) = 1, we start at the point (0, 1) and follow the direction indicated by the slope field, drawing a smooth curve that matches the general shape of the slope field lines. This curve represents an approximate solution to the initial value problem.

a) H0: μ = 62 (The mean retirement age has not changed), HA: μ > 62 (The mean retirement age has increased) b) p-value is 0.031 c) Mean retirement age has increased

a. To construct the hypotheses, we need to define the null hypothesis (H0) and the alternative hypothesis (HA).

H0: μ = 62 (The mean retirement age has not changed)
HA: μ > 62 (The mean retirement age has increased)

b. To find the p-value, we need to look up the t-distribution table for t37 = 1.92 and α = 0.05. Since the economist is looking for an increase in the mean retirement age, this is a one-tailed test. The degrees of freedom (df) are equal to the sample size minus one (38 - 1 = 37).

Using a t-distribution table or calculator, we find the p-value for t37 = 1.92 is approximately 0.031.

c. Since the p-value (0.031) is less than the significance level α (0.05), the economist should reject the null hypothesis (H0) and conclude that the mean retirement age has increased.

The correct explanation for preferring the mean over the median as a measure of center is option 3: The mean is the same as the median for symmetric data.

The mean over the median as a measure of center is that the mean takes into account all values in a data set, making it more representative of the data as a whole. On the other hand, the median only considers the middle value(s), and is less sensitive to outliers. This means that extreme values in a data set have less impact on the median than they do on the mean. However, if the data set is skewed or has outliers that significantly affect the mean, the median may be a better measure of central tendency. In summary, the choice between the mean and the median depends on the characteristics of the data set being analyzed and the research question being asked.
In symmetric data, the mean and median provide the same central value, giving an accurate representation of the data's center. However, it's important to note that the mean is more sensitive to outliers than the median, which might affect its accuracy in skewed data sets.

To find the center of mass of a thin plate with constant density covering the region D bounded by the parabola x = y^2 and the line x = y, we can use the concept of double integrals and the formula for the center of mass.

The center of mass is the point (x_c, y_c) where the mass is evenly distributed. The x-coordinate of the center of mass can be found by evaluating the double integral of the product of the density and the x-coordinate over the region D, and the y-coordinate of the center of mass can be found similarly.

The region D bounded by the parabola x = y^2 and the line x = y can be expressed in terms of the variables x and y as follows: D = {(x, y) | 0 ≤ y ≤ x ≤ y^2}.

The formula for the center of mass of a thin plate with constant density is given by (x_c, y_c) = (M_x / M, M_y / M), where M_x and M_y are the moments about the x and y axes, respectively, and M is the total mass.

To calculate M_x and M_y, we integrate the product of the density (which is constant) and the x-coordinate or y-coordinate, respectively, over region D.

By performing the double integrals, we can obtain the values of M_x and M_y. Then, by dividing them by the total mass M, we can find the coordinates (x_c, y_c) of the center of mass.

In conclusion, to find the center of mass of the thin plate covering region D, we need to evaluate the double integrals of the x-coordinate and y-coordinate over D and divide the resulting moments by the total mass.

The position vector for the particle is r(t) = [tex](5/6 t^3, -4 sin(t), (1/25) (-cos(5t))) + (3, 5, -1)[/tex]

To find the position vector for a particle with the given acceleration, initial velocity, and initial position, we can integrate the acceleration twice.

a(t) = (5t, 4 sin(t), cos(5t))

v(0) = (-1, 5, 2)

r(0) = (3, 5, -1)

First, we integrate the acceleration to find the velocity function v(t):

∫(a(t)) dt = ∫((5t, 4 sin(t), cos(5t))) dt

v(t) = (5/2 t^2, -4 cos(t), (1/5) sin(5t)) + C1

Using the initial velocity v(0) = (-1, 5, 2), we can find C1:

C1 = (-1, 5, 2) - (0, 0, 0) = (-1, 5, 2)

Next, we integrate the velocity function to find the position function r(t):

∫(v(t)) dt = ∫((5/2 t^2, -4 cos(t), (1/5) sin(5t))) dt

r(t) = (5/6 t^3, -4 sin(t), (1/25) (-cos(5t))) + C2

Using the initial position r(0) = (3, 5, -1), we can find C2:

C2 = (3, 5, -1) - (0, 0, 0) = (3, 5, -1)

Therefore, the position vector for the particle is:

The profit equation for the electric bike production is P(x) = 0.04x^2 + 56x - 200. To find the maximum profit, we first calculate P'(x), the derivative of P(x) with respect to x. Then, by finding the critical points and evaluating the second derivative, we can determine the value of x at which the profit is at a maximum. Finally, substituting this value back into the profit equation, we can calculate the maximum profit.

a) The revenue equation, R(x), is obtained by multiplying the number of bikes produced, x, by the selling price per bike, p(x). Therefore, R(x) = x * p(x). Substituting the given selling price equation p(x) = 90 - 0.02x, we have R(x) = x * (90 - 0.02x).

b) The profit equation, P(x), is calculated by subtracting the cost equation C(x) from the revenue equation R(x). Substituting the given cost equation C(x) = 200 + 34x + 0.02x^2, we have P(x) = R(x) - C(x). Expanding and simplifying, we get P(x) = 0.04x^2 + 56x - 200.

c) To find the value of x at which the profit is at a maximum, we need to find the critical points of P(x). We calculate P'(x), the derivative of P(x), which is P'(x) = 0.08x + 56. Setting P'(x) equal to zero and solving for x, we find x = -700.

Next, we evaluate the second derivative of P(x), denoted as P''(x), which is equal to 0.08. Since P''(x) is a constant, we can determine that P''(x) > 0, indicating a concave-up parabola.

Since P''(x) > 0 and the critical point x = -700 corresponds to a minimum, there is no maximum profit.

d) Therefore, there is no maximum profit. The profit equation P(x) = 0.04x^2 + 56x - 200 represents a concave-up parabola with a minimum value at x = -700.

To evaluate the definite integral ∫[0 to 1] (x^8 / (1 + x)) dx, we can use the technique of partial fraction decomposition combined with the second part of the Fundamental Theorem of Calculus. The exact value of the integral is (127/7) - (1/7) - (59/6) + (43/5) - (7/3) + (1/4) + 7 - ln(2), and the approximate value rounded to 4 decimal places is approximately 18.1429 - ln(2).

First, let's rewrite the integrand as a sum of fractions:

x^8 / (1 + x) = x^8 / (x + 1)

To perform partial fraction decomposition, we express the integrand as a sum of simpler fractions:

x^8 / (x + 1) = A/(x + 1) + Bx^7/(x + 1)

To find the values of A and B, we can multiply both sides of the equation by (x + 1) and then equate the coefficients of corresponding powers of x. This gives us:

x^8 = A(x + 1) + Bx^7

Expanding the right side and comparing coefficients, we get:

1x^8 = Ax + A + Bx^7

Equating coefficients:

A = 0 (from the term without x)

1 = A + B (from the term with x^8)

Therefore, A = 0 and B = 1.

Now, we can rewrite the integral as:

∫[0 to 1] (x^8 / (1 + x)) dx = ∫[0 to 1] (1/(1 + x)) dx + ∫[0 to 1] (x^7 / (1 + x)) dx

The first integral is a standard integral that can be evaluated using the natural logarithm function:

∫[0 to 1] (1/(1 + x)) dx = ln|1 + x| |[0 to 1] = ln|1 + 1| - ln|1 + 0| = ln(2) - ln(1) = ln(2)

For the second integral, we can use the substitution u = 1 + x:

∫[0 to 1] (x^7 / (1 + x)) dx = ∫[1 to 2] ((u - 1)^7 / u) du

Simplifying the integrand:

((u - 1)^7 / u) = (u^7 - 7u^6 + 21u^5 - 35u^4 + 35u^3 - 21u^2 + 7u - 1) / u

Now we can integrate term by term:

∫[1 to 2] (u^7 / u) du - ∫[1 to 2] (7u^6 / u) du + ∫[1 to 2] (21u^5 / u) du - ∫[1 to 2] (35u^4 / u) du + ∫[1 to 2] (35u^3 / u) du - ∫[1 to 2] (21u^2 / u) du + ∫[1 to 2] (7u / u) du - ∫[1 to 2] (1 / u) du

Simplifying further:

∫[1 to 2] u^6 du - ∫[1 to 2] 7u^5 du + ∫[1 to 2] 21u^4 du - ∫[1 to 2] 35u^3 du + ∫[1 to 2] 35u^2 du - ∫[1 to 2] 21u du + ∫[1 to 2] 7 du - ∫[1 to 2] (1/u) du

Integrating each term:

[(1/7)u^7] [1 to 2] - [(7/6)u^6] [1 to 2] + [(21/5)u^5] [1 to 2] - [(35/4)u^4] [1 to 2] + [(35/3)u^3] [1 to 2] - [(21/2)u^2] [1 to 2] + [7u] [1 to 2] - [ln|u|] [1 to 2]

Evaluating the limits and simplifying:

[(1/7)2^7 - (1/7)1^7] - [(7/6)2^6 - (7/6)1^6] + [(21/5)2^5 - (21/5)1^5] - [(35/4)2^4 - (35/4)1^4] + [(35/3)2^3 - (35/3)1^3] - [(21/2)2^2 - (21/2)1^2] + [7(2 - 1)] - [ln|2| - ln|1|]

Simplifying further:

[(128/7) - (1/7)] - [(64/3) - (7/6)] + [(64/5) - (21/5)] - [(16/1) - (35/4)] + [(8/1) - (35/3)] - [(84/2) - (21/2)] + [7] - [ln(2) - ln(1)]

Simplifying the fractions:

(127/7) - (1/7) - (59/6) + (43/5) - (7/3) + (1/4) + 7 - ln(2)

Approximating the numerical value: ≈ 18.1429 - ln(2)

To calculate the angle of elevation required to hit an object 160 meters away with a muzzle speed of 80 meters per second and neglecting air resistance, we can use the kinematic equations of motion.

Let's consider the motion in the vertical and horizontal directions separately. In the horizontal direction, the object travels a distance of 160 meters.

We can use the equation for horizontal motion, which states that distance equals velocity multiplied by time (d = v * t).

Since the horizontal velocity remains constant, the time of flight (t) is given by the distance divided by the horizontal velocity, which is 160/80 = 2 seconds.

In the vertical direction, we can use the equation for projectile motion, which relates the vertical displacement, initial vertical velocity, time, and acceleration due to gravity.

The vertical displacement is given by the equation:

d = v₀ * t + (1/2) * g * t², where v₀ is the initial vertical velocity and g is the acceleration due to gravity.

The initial vertical velocity can be calculated using the vertical component of the muzzle velocity, which is v₀ = v * sin(θ), where θ is the angle of elevation.

Plugging in the known values, we have

2 = (80 * sin(θ)) * t + (1/2) * 9.8 * t².

Substituting t = 2, we can solve this equation for θ.

Simplifying the equation, we get 0 = 156.8 * sin(θ) + 19.6. Rearranging, we have sin(θ) = -19.6/156.8 = -0.125.

Taking the inverse sine ([tex]sin^{-1}[/tex]) of both sides,

we find that θ ≈ -7.18 degrees.

Therefore, an angle of elevation of approximately 7.18 degrees should be used to hit the object 160 meters away with a muzzle speed of 80 meters per second, neglecting air resistance and using g = 9.8 m/s² as the acceleration due to gravity.

The circulation of field F around the closed curve C is 0.

To calculate the circulation of a vector field around a closed curve, we can use the line integral of the vector field along the curve. The formula gives the circulation:

Circulation = ∮C F ⋅ dr

In this case, the vector field F is given by F = -3x^2y i + xy^2 j, and the curve C is defined parametrically as r(t) = 3cos(t)i + 3sin(t)j, where t ranges from 0 to 2π.

We can calculate the line integral by substituting the parametric equations of the curve into the vector field:

∮C F ⋅ dr = ∫(F ⋅ r'(t)) dt

Calculating F ⋅ r'(t), we get:

F ⋅ r'(t) = (-3(3cos(t))^2(3sin(t)) + (3cos(t))(3sin(t))^2) ⋅ (-3sin(t)i + 3cos(t)j)

Simplifying further, we have:

F ⋅ r'(t) = -27cos^2(t)sin(t) + 27cos(t)sin^2(t)

Integrating this expression with respect to t over the range 0 to 2π, we find that the circulation equals 0.

The correct order for the rushing yards from least to greatest for the top 5 quarterbacks in the state is:
A) -20, -5, 10, 15, 40

The quarterback with the least rushing yards for that week had -20, followed by -5, then 10, 15, and the quarterback with the most rushing yards had 40. It's important to note that negative rushing yards can occur if a quarterback is sacked behind the line of scrimmage or loses yardage on a play. Therefore, it's not uncommon to see negative rushing yards for quarterbacks. The answer option A is the correct order because it starts with the lowest negative number and then goes in ascending order towards the highest positive number.

Option A is correct for the given question.

a. The volume of the solid lying under the hyperbolic paraboloid z = [tex]3y^2[/tex] − [tex]x^2[/tex] + 5 and above the rectangle R = [-1, 1] × [1, 2] is 24 cubic units.

b. The average value of f(x, y) = [tex]2x^2y[/tex] over the rectangle R with vertices (-4, 0), (-4, 5), (4, 5), and (4, 0) is 192/3.

To find the volume of the solid, we need to evaluate the double integral of the hyperbolic paraboloid over the given rectangle R. The volume can be calculated using the formula:

V = ∬R f(x, y) dA

In this case, the function f(x, y) is given as [tex]3y^2 − x^2[/tex] + 5. Integrating f(x, y) over the rectangle R, we have:

V = ∫[1, 2] ∫[-1, 1] ([tex]3y^2 - x^2[/tex] + 5) dx dy

Evaluating this double integral, we find that the volume of the solid is 24 cubic units.

To find the average value of f(x, y) = [tex]2x^2y[/tex] over the rectangle R, we need to calculate the average value as:

Avg(f) = (1/|R|) ∬R f(x, y) dA

Where |R| represents the area of the rectangle R. In this case, |R| is calculated as (4 - (-4))(5 - 0) = 40.

Therefore, the average value of f(x, y) over the rectangle R is:

Avg(f) = (1/40) ∫[0, 5] ∫[-4, 4] ([tex]2x^2y[/tex]) dx dy

Computing this double integral, we find that the average value of f over the rectangle R is 192/3.

The limiting value of the population P(t) as time approaches infinity is P = 10¹⁰ or 10,000,000,000.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

To find the limiting value of the population P(t), we need to consider the behavior of the population as time approaches infinity.

The given initial value problem is:

dP/dt = P(10⁻⁴ - 10⁻¹⁴P), P(0) = 500000000.

To find the limiting value, we set the derivative dP/dt equal to zero:

0 = P(10⁻⁴ - 10⁻¹⁴P).

From this equation, we have two possibilities:

P = 0: If the population reaches zero, it will remain at zero as time goes on.

10⁻⁴ - 10⁻¹⁴P = 0: Solving this equation for P, we get:

10⁻¹⁴P = 10⁻⁴

P = (10⁻⁴)/(10⁻¹⁴)

P = 10¹⁰

Therefore, the limiting value of the population P(t) as time approaches infinity is P = 10¹⁰ or 10,000,000,000.

Therefore, the coordinates of point B are approximately (3.8, 6.8) that is option A.

To find the coordinates of point B, we can use the concept of a ratio and the formula for finding a point along a line segment.

Let's assume the coordinates of point B are (x, y).

The ratio of AB to BC is given as 2:3. This means that the distance from point A to point B is two-fifths of the total distance from point A to point C.

We can calculate the distance between points A and C using the distance formula:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

Substituting the given values:

d = √((5 - 3)² + (11 - 4)²)

d = √(2² + 7²)

d = √(4 + 49)

d = √53

Now, we can set up the ratio equation based on the distances:

AB / BC = 2/3

(√53 - AB) / (BC - √53) = 2/3

Next, we substitute the coordinates of points A and C into the ratio equation:

(√53 - 4) / (5 - √53) = 2/3

To solve this equation, we can cross-multiply and solve for (√53 - 4):

3(√53 - 4) = 2(5 - √53)

3√53 - 12 = 10 - 2√53

5√53 = 22

√53 = 22/5

Now, we substitute this value back into the equation to find B:

x = 3 + 2√53/5 ≈ 3.8

y = 4 + 7√53/5 ≈ 6.8

To solve this problem using the inclusion-exclusion principle, we need to consider the number of ways to roll eight distinct dice such that all six faces appear on at least one die.

Let's denote the six faces as F1, F2, F3, F4, F5, and F6.

First, we'll calculate the total number of ways to roll eight dice without any restrictions. Since each die has six possible outcomes, there are 6^8 total outcomes.

Next, we'll calculate the number of ways where at least one face is missing. Let's consider the number of ways where F1 is missing on at least one die. We can choose 7 dice out of 8 to be any face except F1. The remaining die can have any of the six faces. Therefore, the number of ways where F1 is missing on at least one die is (6^7) * 6.

Similarly, the number of ways where F2 is missing on at least one die is (6^7) * 6, and so on for F3, F4, F5, and F6.

However, if we simply add up these individual counts, we will be overcounting the cases where more than one face is missing. To correct for this, we need to subtract the counts for each pair of missing faces.

Let's consider the number of ways where F1 and F2 are both missing on at least one die. We can choose 6 dice out of 8 to have any face except F1 or F2. The remaining 2 dice can have any of the remaining four faces. Therefore, the number of ways where F1 and F2 are both missing on at least one die is (6^6) * (4^2).

Similarly, the number of ways for each pair of missing faces is (6^6) * (4^2), and there are 15 such pairs (6 choose 2).

However, we have subtracted these pairs twice, so we need to add them back once.

Continuing this process, we consider triplets of missing faces, subtract the counts, and then add back the counts for quadruplets, and so on.

Finally, we obtain the total number of ways to roll eight distinct dice with all six faces appearing using the inclusion-exclusion formula:

Total ways = 6^8 - 6 * (6^7) + 15 * (6^6) * (4^2) - 20 * (6^5) * (3^3) + 15 * (6^4) * (2^4) - 6 * (6^3) * (1^5) + (6^2) * (0^6)

The partial fraction decomposition of B/(A(x-4)(x+3)² + C/(x+3)² is of the form B/(x-4) + A/(x+3) + C/(x+3)².

To perform partial fraction decomposition, we decompose the given rational expression into a sum of simpler fractions. The form of the decomposition is determined by the factors in the denominator.

In the given expression B/(A(x-4)(x+3)² + C/(x+3)², we have two distinct factors in the denominator: (x-4) and (x+3)². Thus, the partial fraction decomposition will consist of three terms: one for each factor and one for the repeated factor.

The first term will have the form B/(x-4) since (x-4) is a linear factor. The second term will have the form A/(x+3) since (x+3) is also a linear factor. Finally, the third term will have the form C/(x+3)² since (x+3)² is a repeated factor.

Therefore, the correct form of the partial fraction decomposition is B/(x-4) + A/(x+3) + C/(x+3)².

Answer: Limit Comparison Test is inconclusive for this series.

Step-by-step explanation: To compare the given series using the Limit Comparison Test, we need to determine which series (A, B, or C) to compare them with and whether they converge or diverge. Let's analyze each series individually:

1. ∑(n=1 to ∞) (17n^2 + 4n + n^3) / (5617n^3 + 7n + 3)

To apply the Limit Comparison Test, we need to choose a series to compare it with. Let's compare it with series A.

Series A: ∑(n=1 to ∞) 1/n^2

Taking the limit of the ratio of the given series to series A as n approaches infinity:

lim (n→∞) [(17n^2 + 4n + n^3) / (5617n^3 + 7n + 3)] / (1/n^2)

lim (n→∞) [(17n^2 + 4n + n^3) / (5617n^3 + 7n + 3)] * (n^2/1)

lim (n→∞) [(17 + 4/n + 1/n^2) / (5617 + 7/n^2 + 3/n^3)]

lim (n→∞) [17/n^2 + 4/n^3 + 1/n^4] / [5617/n^3 + 7/n^4 + 3/n^5]

0 / 0 (indeterminate form)

Since we have an indeterminate form, we can simplify the expression further by dividing every term by n^5:

lim (n→∞) [17/n^7 + 4/n^8 + 1/n^9] / [5617/n^8 + 7/n^9 + 3/n^10]

0 / 0 (still an indeterminate form)

To determine the limit, we can apply L'Hôpital's Rule by taking the derivatives of the numerator and denominator successively until we obtain a determinate form:

lim (n→∞) [0 + 0 + 0] / [0 + 0 + 0]

lim (n→∞) 0 / 0 (still an indeterminate form)

Applying L'Hôpital's Rule once more:

lim (n→∞) [0 + 0 + 0] / [0 + 0 + 0]

lim (n→∞) 0 / 0 (still an indeterminate form)

After several applications of L'Hôpital's Rule, we still have an indeterminate form. This means the Limit Comparison Test is inconclusive for this series.

Therefore, we cannot determine whether the series converges or diverges by using the Limit Comparison Test with series A.

To find the minimum value of the function y = a sin(x) + c, we need to determine the minimum value of the sine function.

The sine function has a maximum value of 1 and a minimum value of -1. Therefore, the minimum value of the function y = a sin(x) + c occurs when the sine function takes its minimum value of -1.

Substituting a = 40.50 and c = 2 into the function, we have: y = 40.50 sin(x) + 2. When sin(x) = -1, the function reaches its minimum value. So we can write: y = 40.50(-1) + 2.  Simplifying, we get: y = -40.50 + 2. y = -38.50. Therefore, the minimum value of the function y = 40.50 sin(x) + 2 is -38.50.

we compute the derivative with respect to x (fx) and the derivative with respect to y (fy). Additionally, we can evaluate these derivatives at specific points, such as fx(5, -5) and fy(-7, 2).

To find the partial derivative fx, we differentiate f(x, y) with respect to x while treating y as a constant. Applying the chain rule, we have fx = (1/2)(x² + y²)^(-1/2) * 2x = x/(√(x² + y²)).

To find the partial derivative fy, we differentiate f(x, y) with respect to y while treating x as a constant. Similar to fx, applying the chain rule, we have fy = (1/2)(x² + y²)^(-1/2) * 2y = y/(√(x² + y²)).

To evaluate fx at the point (5, -5), we substitute x = 5 and y = -5 into the expression for fx: fx(5, -5) = 5/(√(5² + (-5)²)) = 5/√50 = √2.

Similarly, to evaluate fy at the point (-7, 2), we substitute x = -7 and y = 2 into the expression for fy: fy(-7, 2) = 2/(√((-7)² + 2²)) = 2/√53.

Therefore, the partial derivatives of f(x, y) are fx = x/(√(x² + y²)) and fy = y/(√(x² + y²)). At the points (5, -5) and (-7, 2), fx evaluates to √2 and fy evaluates to 2/√53, respectively.
