Susan wants to make pumpkin bread and zucchini bread for the school bake sale. She has 15 eggs and 16 cups of flour in her pantry. Her recipe for one loaf of pumpkin bread uses 2 eggs and 3 cups of flour. Her recipe for one loaf of zucchini bread uses 3 eggs and 4 cups of flour. She plans to sell pumpkin bread loaves for $5 each and zucchini bread loaves for $4 each. Susan wants to maximize the money raised at the bake sale. Let x represent the number of loaves of pumpkin bread and y represent the number of loaves of zucchini bread Susan bakes.

What is the objective function for the problem?
P = 15x + 16y
P = 5x + 7y
P = 5x + 4y
P = 4x + 5y

Answers

The objective function represents the quantity that you want to maximize or minimize in an optimization problem. In this case, Susan wants to maximize the money raised at the bake sale.

The amount of money raised can be calculated by multiplying the number of pumpkin bread loaves (x) by the selling price of each pumpkin bread loaf ($5), and adding it to the product of the number of zucchini bread loaves (y) and the selling price of each zucchini bread loaf ($4).

Therefore, the objective function for this problem is:
P = 5x + 4y

So, the correct option is:
P = 5x + 4y

How to obtain the distance between two points?

The coordinates of the points have the following format:

\((x_1, y_1)\) and \((x_2,y_2)\)

Hence the distance is given as follows:

\(D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

The length of a segment is given by the distance between it's two endpoints.

Hence the length of segment LF is given as follows:

\(D_{LF} = \sqrt{(3 - (-2))^2+(1 - 3)^2}\)

\(D_{LF} = \sqrt{29}\)

\(D_{LF} = 5.4\)

The length of segment JR is given as follows:

\(D_{JR} = \sqrt{(-3 - (-1))^2+(2 - 1)^2}\)

\(D_{JR} = \sqrt{5}\)

\(D_{JR} = 2.2\)

Answers

All lines parallel to y=2x-3 will have the same slope as y=2x-3. So how do you find the slope of y=2x-3? Very simple! When written in slope-intercept form you simply look at the coefficient of the ‘x’ term. In this instance the coefficient is 2. Therefore any equation that has a slope of 2 will be parallel to y=2x-3. In general we can say that the family of equations parallel to y=2x-3 is y=2x+b where b is the y-intercept.

Consider a population with a known standard deviation of 27.5. In order to compute an interval estimate for the population mean, a sample of 69 observations is drawn. [You may find it useful to reference the z table.]
a. Is the condition that X−X− is normally distributed satisfied?
Yes
No
b. Compute the margin of error at a 99% confidence level. (Round intermediate calculations to at least 4 decimal places. Round "z" value to 3 decimal places and final answer to 2 decimal places.)
c. Compute the margin of error at a 99% confidence level based on a larger sample of 275 observations. (Round intermediate calculations to at least 4 decimal places. Round "z" value to 3 decimal places and final answer to 2 decimal places.)
d. Which of the two margins of error will lead to a wider confidence interval?
99% confidence with n = 69.
99% confidence with n = 275.

Answers

The margin of error at a 99% confidence level is 8.36.

The margin of error at a 99% confidence level based on a larger sample of 275 observations is 4.14.

a. Yes, the condition that X−X− is normally distributed is satisfied for a sample size of 69 by the central limit theorem.

b. The margin of error at a 99% confidence level can be computed using the formula:

Margin of error = z* (sigma / sqrt(n))

where z* is the z-score corresponding to a 99% confidence level, sigma is the known standard deviation, and n is the sample size.

The z-score for a 99% confidence level is 2.576 (from the z table).

Substituting the given values, we get:

Margin of error = 2.576 * (27.5 / sqrt(69)) = 8.36

c. The margin of error at a 99% confidence level based on a larger sample of 275 observations can be computed using the same formula:

Margin of error = z* (sigma / sqrt(n))

where z* is the z-score corresponding to a 99% confidence level, sigma is the known standard deviation, and n is the sample size.

The z-score for a 99% confidence level is still 2.576 (from the z table).

Substituting the given values, we get:

Margin of error = 2.576 * (27.5 / sqrt(275)) = 4.14

d. The margin of error is inversely proportional to the square root of the sample size. As the sample size increases, the margin of error decreases. Therefore, the margin of error with n = 275 will be smaller than the margin of error with n = 69, leading to a narrower confidence interval.

How to obtain the numeric values of the function?

The numeric values for the function are obtained applying the operations from the table.

For the addition, we just add the numeric values, hence:

(f + g)(3) = f(3) + g(3) = 8 + 1 = 9.

For the multiplication, we just multiply the values, hence:

(f x g)(-1) = f(-1) x g(-1) = -2 x 4 = -8.

For the composition, the output of the inner function is the input to the outer function, hence:

(f ∘ g)(2) = f(g(2)) = f(3) = 8.(g ∘ f)(0) = g(f(0)) = g(0) = 2.(g ∘ g)(3) = g(g(3)) = g(1) = -1.

Answers

the derivative f'(x) of the function f(x) = e^(3x)/(3x) is given by:

f'(x) = (9xe^(3x) - 3e^(3x)) / (9x^2)

To find the derivative f'(x) of the function f(x) = e^(3x)/(3x), we will use the quotient rule.

The quotient rule states that if we have a function in the form of g(x)/h(x), then its derivative is given by:

(g'(x)h(x) - g(x)h'(x))/(h(x))^2

Here, g(x) = e^(3x) and h(x) = 3x.

Step 1: Find the derivatives of g(x) and h(x).
g'(x) = d(e^(3x))/dx = 3e^(3x)
h'(x) = d(3x)/dx = 3

Step 2: Apply the quotient rule.
f'(x) = (g'(x)h(x) - g(x)h'(x))/(h(x))^2
f'(x) = (3e^(3x) * 3x - e^(3x) * 3) / (3x)^2

Step 3: Simplify the expression.
f'(x) = (9xe^(3x) - 3e^(3x)) / (9x^2)

The row of Pascal's triangle that corresponds to n=9 is as follows:
1 9 36 84 126 126 84 36 9 1
What is the row that corresponds to n=10?

Answers

To find the row that corresponds to n=10 in Pascal's triangle, we will need to use the formula for calculating the value of each entry in the row. The formula is given by:
C(n, k) = n! / (k! * (n - k)!)

where C(n, k) represents the value of the entry at row n and column k.
Using this formula, we can find the entries for row n=10 as follows:
C(10, 0) = 10! / (0! * 10!) = 1
C(10, 1) = 10! / (1! * 9!) = 10
C(10, 2) = 10! / (2! * 8!) = 45
C(10, 3) = 10! / (3! * 7!) = 120
C(10, 4) = 10! / (4! * 6!) = 210
C(10, 5) = 10! / (5! * 5!) = 252
C(10, 6) = 10! / (6! * 4!) = 210
C(10, 7) = 10! / (7! * 3!) = 120
C(10, 8) = 10! / (8! * 2!) = 45
C(10, 9) = 10! / (9! * 1!) = 10
C(10, 10) = 10! / (10! * 0!) = 1
Therefore, the row that corresponds to n=10 is:
1 10 45 120 210 252 210 120 45 10 1
This row has a similar shape to the previous row, but with larger values in each entry. Pascal's triangle is a fascinating mathematical object with many interesting properties, and it has been studied by mathematicians for centuries.

It's a beautiful day for a soccer game on the Oberlin College campus. A soccer ball is sitting midfield and is being heated by the sun. Suppose that we set up coordinate axes so that the center of the ball is at the origin and suppose that the surface of the ball is approximated by a sphere with equation x2 + y2 + z2 = 126 in some system of units. Suppose that the temperature in the space in and around the ball is given by the function T(x,y.z) = x + 2y + 3z. (b) (3 points) Explain why there must be both coldest and hottest point on the surface of the soccer ball. (c) (14 points) Find all the coldest and hottest point on the surface of the soccer ball.

Answers

(a) There must be both coldest and hottest points on the surface of the soccer ball because the of the temperature function (b). The coldest point on the surface of the soccer ball is (3, 6, 9) and the hottest point is (-3, -6, -9).

(b) There must be both coldest and hottest points on the surface of the soccer ball because the temperature function T(x, y, z) = x + 2y + 3z is a linear function in the variables x, y, and z.

Considering the equation of the sphere x² + y² + z²= 126, which represents the surface of the soccer ball, the temperature function T(x, y, z) is a linear combination of x, y, and z.

Since the coefficients of x, y, and z are all positive (1, 2, and 3 respectively), as we move along the surface of the ball, the temperature will increase or decrease depending on the direction we move in. This means that there will be points on the surface where the temperature is at its maximum (hottest points) and points where the temperature is at its minimum (coldest points).

(c) To find the coldest and hottest points on the surface of the soccer ball, we need to optimize the temperature function T(x, y, z) = x + 2y + 3z subject to the constraint x²+ y²+ z² = 126.

To find the coldest point, we need to minimize T(x, y, z) under the given constraint. This can be done using Lagrange multipliers. Setting up the Lagrangian function:

L(x, y, z, λ) = T(x, y, z) - λ(x² + y² + z²- 126)

Taking partial derivatives and setting them equal to zero:

∂L/∂x = 1 - 2λx = 0

∂L/∂y = 2 - 2λy = 0

∂L/∂z = 3 - 2λz = 0

∂L/∂λ = -(x² + y²+ z² - 126) = 0

Solving these equations, we find:

x = 1/(2λ)

y = 2/(2λ)

z = 3/(2λ)

Substituting these values back into the constraint equation x² + y² + z² = 126, we get:

(1/(2λ))² + (2/(2λ))² + (3/(2λ))² = 126

14/(4λ²) = 126

λ^2 = 1/9

λ = ±1/3

Using λ = 1/3, we find:

x = 3

y = 6

z = 9

Therefore, the coldest point on the surface of the soccer ball is (3, 6, 9).

To find the hottest point, we can use the same process with the opposite sign of λ. Using λ = -1/3, we find:

x = -3

y = -6

z = -9

Therefore, the hottest point on the surface of the soccer ball is (-3, -6, -9).
