To ensures the function is continuous at x = 4, g(4) is equal to 136,
To define g(4) such that the function is continuous at x = 4, we need to find the value of g(4) that makes the function continuous at that point.
The given function is defined as: f(x) = 2x - 32, for x < 4 , f(x) = 9x^2 - 8, for x ≥ 4. To make the function continuous at x = 4, we set g(4) equal to the value of the function at that point. g(4) = f(4)
Since 4 is equal to or greater than 4, we use the second part of the function:
g(4) = 9(4)^2 - 8
g(4) = 9(16) - 8
g(4) = 144 - 8
g(4) = 136
Therefore, g(4) is equal to 136, which ensures the function is continuous at x = 4.

mr. way must sell stocks from 3 of the 6 companies whose stocks he owns so that he can send his children to college. if he chooses the companies at random, what is the probability that the 3 companies will be the 3 with the best future earnings? (enter your probability as a fraction.)
The probability that the 3 companies will be the 3 with the best future earnings is 5/100 .
There are a total of 20 possible combinations of 3 companies that Mr. Way can sell stocks from. However, we are only interested in the probability of him selecting the 3 companies with the best future earnings. Since we do not know the actual future earnings of each company, we can assume that all 6 companies have an equal chance of being in the top 3.
Therefore, the probability of Mr. Way selecting the 3 companies with the best future earnings is the same as the probability of selecting any specific set of 3 companies out of the 6.
The number of ways to select 3 companies out of 6 is given by the combination formula, which is:
6! / (3! x 3!) = 20
Therefore, the probability of Mr. Way selecting the 3 companies with the best future earnings is 1/20. So, the answer is:
Probability = 1/20
This can also be written as a fraction, which is probability = 0.05 or 5/100

Therefore, the total work done at each level is d * (n/2^i). Summing up the work done at all levels, we get: c(n) = d * (n/2^0 + n/2^1 + n/2^2 + ... + n/2^log(n)).
The basic operation in the algorithm is comparing the value of each element in the array with the given integer k. We can construct a recurrence relation to represent the time complexity of the algorithm.
Let's define c(n) as the time complexity of the algorithm for an array of length n. The recurrence relation can be expressed as follows:
c(n) = 2c(n/2) + d,
where c(n/2) represents the time complexity for an array of length n/2 (as the array is divided into two halves in each recursive call), and d represents the time complexity of the comparisons and other constant operations performed in each recursive call.
To determine the order of growth for c(n), we can solve the recurrence relation using the recursion tree or the Master theorem.
Using the recursion tree method, we can observe that the algorithm divides the array into halves recursively until the array size becomes 1. At each level of the recursion tree, the total work done is d times the number of elements at that level, which is n/2^i (where i represents the level of recursion).

The area of triangle ABC with
vertices A(0,0), B(-6,5), and C(5,3), is 21 square units.
To find the area of the triangle, we can use the formula for the area of a triangle formed by three points in a coordinate plane. Let's label the vertices as A(x₁, y₁), B(x₂, y₂), and C(x₃, y₃). The formula of the triangle formed by these vertices is:
Area = 1/2 * |x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂)|
Plugging in the coordinates of the given vertices, we have:Area = 1/2 * |0(5 - 3) + (-6)(3 - 0) + 5(0 - 5)|
Simplifying further:
Area = 1/2 * |-18 + 0 - 25|
Area = 1/2 * |-43|
Since the absolute value of -43 is 43, the area of triangle ABC is:
Area = 1/2 * 43 = 21 square units.

A real estate agent believes that the average closing costs when purchasing a new home is $6500. She selects 40 new home sales at random. Among these, the average closing cost is $6600. The standard deviation of the population is $120. At Alpha equals 0.05, test the agents claim.
The 95% cοnfidence interval fοr the average clοsing cοst is ($5,883.21, $7,316.79).
Hοw tο define this hypοtheses?Tο test the real estate agent's belief abοut the average clοsing cοst οf purchasing a new hοme, we will cοnduct a hypοthesis test. Let's define οur hypοtheses:
Null Hypοthesis (H0): The average clοsing cοst is $6,500.
Alternative Hypοthesis (Ha): The average clοsing cοst is nοt equal tο $6,500.
We will use a significance level οf α = 0.05.
Nοw, let's perfοrm the hypοthesis test:
Step 1: Set up the hypοtheses:
H0: μ = $6,500
Ha: μ ≠ $6,500
Step 2: Chοοse the apprοpriate test statistic.
Since we have a sample mean and want tο cοmpare it tο a knοwn value, we can use a οne-sample t-test.
Step 3: Determine the critical value(s) οr p-value.
Since the alternative hypοthesis is twο-sided, we will use a twο-tailed test. With a significance level οf α = 0.05 and a sample size οf n = 40, the degrees οf freedοm are (n-1) = 39. We can lοοk up the critical t-values in a t-distributiοn table οr use statistical sοftware. The critical t-values at α/2 = 0.025 are apprοximately -2.0227 and 2.0227.
Step 4: Calculate the test statistic.
The test statistic fοr a οne-sample t-test is given by:
t = (sample mean - hypοthesized mean) / (sample standard deviatiοn / sqrt(sample size))
In this case:
Sample mean (x) = $6,600
Hypοthesized mean (μ) = $6,500
Sample standard deviatiοn (s) is nοt prοvided, sο we can't calculate the test statistic withοut it.
Step 5: Determine the decisiοn.
Withοut the sample standard deviatiοn, we cannοt calculate the test statistic and make a decisiοn.
Given that the sample standard deviatiοn is nοt prοvided, we cannοt cοmplete the hypοthesis test. Hοwever, we can calculate the 95% cοnfidence interval tο estimate the true pοpulatiοn mean.
Tο find the 95% cοnfidence interval, we can use the fοrmula:
Cοnfidence interval = sample mean ± (critical value * standard errοr)
where the critical value is οbtained frοm the t-distributiοn table fοr a twο-tailed test at α/2 = 0.025, and the standard errοr is the sample standard deviatiοn divided by the square rοοt οf the sample size.
Let's assume the sample standard deviatiοn is $500 (an arbitrary value) fοr the calculatiοn.
Step 6: Calculate the 95% cοnfidence interval.
Using the assumed sample standard deviatiοn οf $500 and the sample size οf n = 40, the standard errοr is:
Standard errοr = sample standard deviatiοn / sqrt(sample size) = $500 / sqrt(40)
The critical value fοr a 95% cοnfidence interval with (n-1) = 39 degrees οf freedοm is apprοximately 2.0227.
Nοw we can calculate the cοnfidence interval:
Cοnfidence interval = $6,600 ± (2.0227 * ($500 / sqrt(40)))
Calculating the values, we get:
Cοnfidence interval = $6,600 ± $716.79
= ($5,883.21, $7,316.79)
The 95% cοnfidence interval fοr the average clοsing cοst is ($5,883.21, $7,316.79).
Cοmparing the hypοthesis test with the cοnfidence interval, if the hypοthesized mean οf $6,500 falls within the cοnfidence interval, it suggests that the null hypοthesis is plausible.
Hοwever, if the hypοthesized mean is οutside the cοnfidence interval, it prοvides evidence tο reject the null hypοthesis.
In this case, withοut the actual sample standard deviatiοn prοvided, we cannοt cοmpare the hypοthesized mean with the cοnfidence interval.

Circle T is shown below the radius is 30 cm what is the arc length terms of pi of UV
The arc length of the arc UV in terms of pi is (θ/360°) × (60π), where θ represents the Central angle of the arc
In the given scenario, a circle T is shown with a radius of 30 cm. We need to determine the arc length of the arc UV in terms of pi.
The arc length of a circle is given by the formula:
Arc Length = θ/360° × 2πr,
where θ is the central angle of the arc and r is the radius of the circle.
Since the central angle θ of the arc UV is not provided, we cannot calculate the exact arc length. However, we can still express it in terms of pi.
To do this, we need to find the ratio of the central angle θ to the full angle of a circle, which is 360 degrees. We can express this ratio as:
θ/360° = Arc Length/(2πr).
Substituting the given radius value of 30 cm into the equation, we have:
θ/360° = Arc Length/(2π × 30).
Simplifying, we get:
θ/360° = Arc Length/(60π).
Now, if we express the arc length in terms of pi, we can rewrite the equation as:
θ/360° = (Arc Length/π)/(60π/π).
θ/360° = (Arc Length/π)/(60).
θ/360° = Arc Length/(60π).
From the equation, we can see that the arc length in terms of pi is equal to θ/360° multiplied by (60π).
Therefore, the arc length of the arc UV in terms of pi is (θ/360°) × (60π), where θ represents the central angle of the arc. Without additional information about the central angle, we cannot provide an exact numerical value for the arc length in terms of pi. time is a multifaceted and pervasive element of human existence.

What type of function is f:ZZ, where f(x) = 2x ? Injective / one-to-one Surjective / onto Bijective / one-to-one correspondence None of the others
The function f: ZZ (integers) defined as f(x) = 2x is an injective or one-to-one function.
An injective or one-to-one function is a function where each input value (x) corresponds to a unique output value (f(x)). In this case, the function f(x) = 2x assigns a unique value to each integer input x by multiplying it by 2.
For example, if we consider two different integers, say x1 and x2, if f(x1) = f(x2), then x1 must be equal to x2 because the function doubles the input. Hence, each input has a unique output, and there are no two distinct integers that map to the same value. This property makes the function f: ZZ (integers) with f(x) = 2x an injective or one-to-one function.

For what value of is the function defined below continuous on (−[infinity],[infinity])? f(x)= { x^2 - c^2, x < 6

The function [tex]f(x) = x^2 - c^2[/tex] for x < 6 and f(x) = cx + 45 for x ≥ 6 is continuous on (-∞, ∞) for all values of c except for c = 0. Consider the definition of continuity.
A function is continuous at a point if the limit of the function as x approaches that point exists and is equal to the value of the function at that point.
For x < 6, the function [tex]f(x) = x^2 - c^2[/tex] is a polynomial function and is continuous for all values of c since polynomials are continuous everywhere.
For x ≥ 6, the function f(x) = cx + 45 is a linear function. Linear functions are also continuous everywhere, regardless of the value of c.
However, at x = 6, we have a point of discontinuity if c = 0. When c = 0, the function becomes f(x) = 45 for x ≥ 6. In this case, the function has a jump discontinuity at x = 6 since the limit as x approaches 6 from the left is not equal to the value of the function at x = 6.
In conclusion, the function [tex]f(x) = x^2 - c^2[/tex] for x < 6 and f(x) = cx + 45 for x ≥ 6 is continuous on (-∞, ∞) for all values of c except when c = 0.

Find (a) the compound amount and (b) the compound interest rate for the given investment and annu $4000 for 5 years at 7% compounded annually (a) The compound amount in the account after 5 years is $ (b) The compound interest earned is $
The future value (A) is approximately 5610.2 for the given investment and annu $4000 for 5 years at 7% compounded annually
To find the compound amount and compound interest rate for the given investment, we can use the formula for compound interest:
(a) The compound amount in the account after 5 years can be calculated using the formula:
A = P(1 + r/n)^(nt)
Where A is the compound amount, P is the principal (initial investment), r is the interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
Given that the principal (P) is $4000, the interest rate ® is 7%, and the interest is compounded annually (n = 1), and the investment is for 5 years (t = 5), we can plug these values into the formula:
A = 4000(1 + 0.07/1)^(1*5)
A = 4000(1 + 0.07/1)^(1*5)
= 4000(1 + 0.07)^(5)
= 4000(1.07)^(5)
≈ 4000(1.402551)
≈ 5610.20
Therefore, the future value (A) is approximately 5610.2
Calculating this expression will give us the compound amount after 5 years.
(b) The compound interest earned can be calculated by subtracting the principal from the compound amount:
Compound interest = Compound amount – Principa
This will give us the total interest earned over the 5-year period.

Find the interval, I, of convergence of the series
The radius of convergence, R, of the series Σ((xn) / (2n − 1)) is determined by the ratio test. The interval of convergence, I, is obtained by analyzing the convergence at the endpoints based on the behavior of the series.
The ratio test states that if the limit of the absolute value of the ratio of consecutive terms of a series is L, then the series converges if L < 1 and diverges if L > 1. If L = 1, the test is inconclusive.
Let's apply the ratio test to the given series:
L = lim(n→∞) |(xn+1 / (2(n+1) − 1)) / (xn / (2n − 1))|
Simplifying the expression:
L = lim(n→∞) |(xn+1 / xn) * ((2n − 1) / (2(n+1) − 1))|
As n approaches infinity, the second fraction tends to 1, and we are left with:
L = lim(n→∞) |xn+1 / xn|
If the limit L exists, it represents the radius of convergence R. If L = 1, the series may or may not converge at the endpoints. If L = 0, the series converges for all values of x.
To determine the interval of convergence, we need to analyze the behavior at the endpoints of the interval. If the series converges at an endpoint, it is included in the interval; if it diverges, the endpoint is excluded.

Let u = (-2, 4) and v = (15, -7). To check if u and v are orthogonal, we calculate their dot product:
u · v = (-2)(15) + (4)(-7) = -30 - 28 = -58

The correct answer is (E) The possible p-values are 0.22 and 0.88.
If the experimenter conducted a one-tailed hypothesis test on the same set of data, the possible p-value(s) that they could have obtained would depend on the direction of the test.
In a one-tailed test, the hypothesis is directional and the experimenter is only interested in one side of the distribution (either the upper or lower tail). Therefore, the p-value would only be calculated for that one side.
If the original two-tailed test had a p-value of 0.44, it means that the null hypothesis was not rejected at the significance level of 0.05 (assuming a common level of significance).
If the experimenter conducted a one-tailed test with a directional hypothesis that was consistent with the direction of the higher tail of the original two-tailed test, then the possible p-value would be 0.22 (half of the original p-value). If the directional hypothesis was consistent with the lower tail of the original two-tailed test, then the possible p-value would be 0.88 (one minus half of the original p-value).
Therefore, the correct answer is (E) The possible p-values are 0.22 and 0.88.

k = ln(2) / 14.2 ≈ 0.04878 (rounded to five decimal places).
Now, we can use the decay formula to find the amount of P-32 present after a certain number of days. In this case, we are asked to find the amount after a specific number of days, which we'll call t.
N(t) = N₀ * e^(-kt)
Given that the initial amount N₀ is 150 g, we can substitute the values into the formula:
N(t) = 150 * e^(-0.04878t)
This formula gives us the amount of P-32 present after t days.
To find the specific amount after a certain number of days, we would substitute the desired value of t into the equation. For example, if we wanted to find the amount after 30 days, we would substitute t = 30 into the equation:
N(30) = 150 * e^(-0.04878 * 30)
Calculating this expression will give us the amount of P-32 present after 30 days.
In conclusion, the amount of Phosphorus-32 (P-32) present after a certain number of days can be found using the radioactive decay formula N(t) = N₀ * e^(-kt), where N₀ is the initial amount, k is the decay constant, and t is the time in days.

The given limit is undefined (DNE) since there are no specific values provided for t and h. The expression cannot be further simplified without knowing the values of t and h. Answer : -16 / (-594 + 30t + 100h)
To evaluate the limit given, let's break it down step by step:
lim (1-7-10)/(4+2+30t-100(6-h))
First, let's simplify the numerator:
1-7-10 = -16

Evaluate the limit using l'Hôpital's Rule x3-8 ca lim X-72 X-2
After substituting 2 in for x, as a result, one obtains the limit as x approaches 2 of (x3-8) / (x-2) = 12.
To evaluate the limit using l'Hôpital's Rule, x3-8ca lim X-72X-2, proceed as follows:
Step 1: Firstly, the limit of the function as x approaches 2 is computed.
This can be done through direct substitution, such that the expression x3-8ca lim X-72X-2 becomes ((2)3 - 8) / ((2) - 7) = (-6).
Step 2: Determine if both the numerator and the denominator of the original expression equal zero. If they do, then one can differentiate each of them separately, divide the resulting equations, and solve for the limit using the new quotient.
Step 3: In this particular case, neither the numerator nor the denominator equate to zero. As a result, one may differentiate the numerator and denominator separately in order to find the limit of the original function. The derivative of the numerator is 3x2, and the derivative of the denominator is 1.
Thus, the derivative of the expression x3-8ca lim X-72X-2 is (3x2) / 1, which equals 12 when x is equal to 2.
Step 4: Divide the numerator and denominator of the original expression by x - 2, and then substitute 2 in for x. As a result, one obtains the limit as x approaches 2 of (x3-8) / (x-2) = 12.

Find dy/dx by implicit differentiation. Vxy = 8 + x^y dy/dx =
The derivative dy/dx is equal to zero, as obtained through the process of implicit differentiation on the given equation.
The derivative dy/dx can be found by using implicit differentiation on the given equation Vxy = 8 + x^y.
To begin, we differentiate both sides of the equation with respect to x, treating y as a function of x:
d/dx(Vxy) = d/dx(8 + x^y).
Using the chain rule, we differentiate each term separately. The derivative of Vxy with respect to x is given by:
dV/dx * (dxy/dx) = 0.
Since dV/dx = 0 (as Vxy is a constant with respect to x), the equation simplifies to:
(dxy/dx) * (dV/dy) = 0.
Now, we can solve for dy/dx:
dxy/dx = 0 / dV/dy = 0.
Therefore, dy/dx = 0.

Pr. #7) Find the absolute extreme values on the given interval. sin 21 2 + cos21
The absolute extreme values on the given interval, sin 21 2 + cos21 is 1. Since the function is continuous on a closed interval, it must have a maximum and a minimum on the interval.
Since sin²(θ) + cos²(θ) = 1 for all θ, we have:
sin²(θ) = 1 - cos²(θ)
cos²(θ) = 1 - sin²(θ)
Therefore, we can write the expression sin²(θ) + cos²(θ) as:
sin²(θ) + cos²(θ) = 1 - sin²(θ) + cos²(θ)
= 1 - (sin²(θ) - cos²(θ))
Now, let f(θ) = sin²(θ) + cos²(θ) = 1 - (sin²(θ) - cos²(θ)).
We want to find the absolute extreme values of f(θ) on the interval [0, 2π].
First, note that f(θ) is a continuous function on the closed interval [0, 2π] and a differentiable function on the open interval (0, 2π).
Taking the derivative of f(θ), we get:
f'(θ) = 2cos(θ)sin(θ) + 2sin(θ)cos(θ) = 4cos(θ)sin(θ)
Setting f'(θ) = 0, we get:
cos(θ) = 0 or sin(θ) = 0
Therefore, the critical points of f(θ) on the interval [0, 2π] occur at θ = π/2, 3π/2, 0, and π.
Evaluating f(θ) at these critical points, we get:
f(π/2) = 1
f(3π/2) = 1
f(0) = 1
f(π) = 1
Therefore, the absolute maximum value of f(θ) on the interval [0, 2π] is 1, and the absolute minimum value of f(θ) on the interval [0, 2π] is also 1.
In summary, the absolute extreme values of sin²(θ) + cos²(θ) on the interval [0, 2π] are both equal to 1.

The demand curve of Lucky Egg in each district is shown as follow:
0 = 1000 - 2P Suppose the manufacturer is the monopolist in the market of production. There are many distributors in the whole market but there is only one distributor in
each district (Each distributor is the monopolist in retail for a particular district). The marginal cost to produce a Lucky egg to the manufacturer is $100. The distribution cost to the distributor is $50 per egg. Determine the quantity transacted between one distributor and manufacturer in one district, quantity transacted between consumer and distributor in one district, the wholesale price
and the retail price respectively.
Manufacturer-retailer transaction volume is 450 lucky eggs, Consumer-retailer transaction volume is 275 lucky eggs, the wholesale price is $550 per egg, and the retail price is $750 per egg for marginal cost.
In one district, the quantity traded between manufacturers and retailers is 450 Lucky Eggs. The quantity traded between consumers and sellers in the district is 275 Lucky Eggs. The wholesale price will be $550 per egg and the retail price will be $750 per egg.
As a market monopoly, the manufacturer controls the production and supply of happy eggs. The demand curve for happy eggs in each district is given by the following equation.
Q = 1000 - 2P, where Q is quantity demanded and P is price.
To find out the quantity transacted between manufacturers and distributors in a region, we need to equate the quantity demanded with the quantity supplied by the manufacturer. The maker's marginal cost to produce a lucky egg is $100. Considering distribution costs of $50 per egg, the manufacturer would accept a floor price of $150 per egg.
Substituting this price into the demand curve equation gives:
Q = 1000 - 2 * 150
Q=700.
Therefore, the quantity traded between the manufacturer and the retailer in a district is 700 happy eggs. Next, subtract the distribution cost of $50 per egg from the wholesale price to determine the quantity transacted between consumers and retailers in the county. Because retailers have a monopoly on the retail market, retail prices are higher than wholesale prices. Let R be the selling price.
Equating the quantity demanded and the quantity supplied by retailers, we get:
700 = 1000 - 2R.
Solving for R gives us the following:
R = (1000 - 700) / 2
R=150. Therefore, the retail price is $750 per egg and the quantity traded between consumers and retailers in the county is 700 – 150 = 550 lucky eggs.
Finally, subtracting the distribution cost of $50 per egg from the retail price gives the wholesale price for the marginal cost.
Wholesale Price = Retail Price – Distribution Cost
Wholesale price = 150 - 50
Wholesale price = $550 per egg.

Parametric equations for the line through (5, 1, 6) that is perpendicular to the plane x - y + 3.2 = 7 is xt = 5 - t, yt = 1 - t, zt = 6. (0, -4, 6) point does this line intersect the coordinate planes.
To find the parametric equations for the line through (5, 1, 6) that is perpendicular to the plane x - y + 3.2 = 7, we first need to determine the direction vector of the line. Since the line is perpendicular to the plane, its direction vector will be perpendicular to the normal vector of the plane.
The normal vector of the plane is (1, -1, 0) since the coefficients of x, y, and z in the plane equation represent the normal vector. To find a direction vector perpendicular to this normal vector, we can take the cross product of (1, -1, 0) with any other vector that is not parallel to it.
Let's choose the vector (0, 0, 1) as the second vector. Taking the cross product:
(1, -1, 0) x (0, 0, 1) = (-1, -1, 0)
So, the direction vector of the line is (-1, -1, 0).
a) Parametric equations for the line:
The parametric equations for the line through (5, 1, 6) with the direction vector (-1, -1, 0) can be written as:
xt = 5 - t
yt = 1 - t
zt = 6
b) Intersection points with the coordinate planes:
To find the points where the line intersects the coordinate planes, we can substitute the appropriate values of t into the parametric equations.
Intersection with the xy-plane (z = 0):
Setting zt = 6 to 0, we have:
6 = 0
This equation has no solution, indicating that the line does not intersect the xy-plane.
Intersection with the xz-plane (y = 0):
Setting yt = 1 - t to 0, we have:
1 - t = 0
t = 1
Substituting t = 1 into the parametric equations:
x(1) = 5 - 1 = 4
y(1) = 1 - 1 = 0
z(1) = 6
The line intersects the xz-plane at the point (4, 0, 6).
Intersection with the yz-plane (x = 0):
Setting xt = 5 - t to 0, we have:
5 - t = 0
t = 5
Substituting t = 5 into the parametric equations:
x(5) = 5 - 5 = 0
y(5) = 1 - 5 = -4
z(5) = 6
The line intersects the yz-plane at the point (0, -4, 6).
Therefore, the line intersects the xz-plane at (4, 0, 6) and the yz-plane at (0, -4, 6).

assume that the histograms are drawn on the same scale. which of the histograms has the largest interquartile range (iqr)?
The interquartile range (IQR) is a measure of variability in a data set and is calculated as the difference between the first and third quartiles.
A larger IQR indicates a greater spread of data. Assuming that the histograms are drawn on the same scale, the histogram with the largest IQR would be the one with the widest spread of data. This can be determined by examining the width of the boxes in each histogram. The box represents the IQR, with the bottom of the box being the first quartile and the top of the box being the third quartile. The histogram with the widest box would have the largest IQR. It is important to note that a larger IQR does not necessarily mean that the data is more spread out than other histograms, as it only measures the middle 50% of the data and ignores outliers. Therefore, it is important to consider other measures of variability and the overall shape of the distribution when interpreting histograms.

The value of the given double integral, ∬(1 to 20) (x + 5y) dy dx over the region -3 to 20, evaluates to -112.
To evaluate the double integral, we start by integrating with respect to y first and then with respect to x.
Integrating with respect to y, we get (x * y + (5/2) * y^2) evaluated from y = -3 to y = 20.
This simplifies to (x * 20 + (5/2) * 20^2) - (x * -3 + (5/2) * (-3)^2). Simplifying further, we have (20x + 200) - (-3x + 22.5).
Combining like terms, we get 23x + 177.5.
Now, we integrate the expression (23x + 177.5) with respect to x from x = 1 to x = 20.
This gives us (23/2 * x^2 + 177.5x) evaluated from x = 1 to x = 20. Substituting the upper and lower limits, we have [(23/2 * 20^2 + 177.5 * 20) - (23/2 * 1^2 + 177.5 * 1)].
Simplifying this expression, we obtain (2300 + 3550) - (23/2 + 177.5).
Finally, we simplify the expression (2300 + 3550) - (23/2 + 177.5) to get 5850 - (23/2 + 177.5).
Evaluating further, we have 5850 - (46/2 + 177.5), which gives us 5850 - (23 + 177.5). Combining like terms, we have 5850 - 200.5. The final result is -112.
Therefore, the value of the given double integral, ∬(1 to 20) (x + 5y) dy dx over the region -3 to 20, evaluates to -112. Thus, option C, -112, is the correct answer.
