A2: a. The four period moving average forecast method is a technique that is used to calculate the demand for a particular month based on the average demand for the previous four months. In this case, to calculate the demand for the month of April 2020, we will take the average of the demand for the months of December, January, February, and March. The formula for this method is:

Four period moving average forecast = (Demand for December + Demand for January + Demand for February + Demand for March) / 4

= (1,450 + 1,410 + 1,420 + 1,380) / 4

= 5,660 / 4

= 1,415

Therefore, the demand for the month of April 2020 is 1,415 loafs.

b. Based on the demand forecast for the month of April 2020, Al Artz Bakery should decide to maintain their current capacity as the demand is relatively stable and there is no significant increase or decrease in demand. This will ensure that they are able to meet the demand without overproducing or underproducing.

c. If the bakery calculated forecasts for all products it makes, the forecast would be more accurate than the one calculated for just one product. This is because it would take into account the demand for all products and would give a more comprehensive view of the overall demand for the bakery.

d. If the bakery decides to use qualitative methods, it could use sources of opinion such as customer feedback, expert opinion, and market research. These sources of opinion can provide valuable insights into the demand for the bakery's products and can help to improve the accuracy of the demand forecast.

Answer:

The function y = 3(x - 2)^2 + 6 is in vertex form, which is y = a(x - h)^2 + k, where (h,k) is the vertex of the parabola.

In this case, the vertex is (2,6), and the coefficient "a" is 3, so we can write the equivalent function in standard form as follows:

y = 3(x - 2)^2 + 6

y = 3(x^2 - 4x + 4) + 6

y = 3x^2 - 12x + 18

Therefore, the equivalent function in standard form is y = 3x^2 - 12x + 18.

The final answer of Using Descartes's Rule of Signs, we can determine that there are either 2 or 0 positive real zeros and 0 negative real zeros of [tex]f(x)=8x^4-7x^3-4x^2-2x+7[/tex]

To determine the possible numbers of positive and negative real zeros of f(x)=8x^(4)-7x^(3)-4x^(2)-2x+7 using Descartes's Rule of Signs, we must first count the number of sign changes in the polynomial.

For positive real zeros, we look at the original polynomial: f(x)=8x^(4)-7x^(3)-4x^(2)-2x+7.

There are two sign changes: from 8x^(4) to -7x^(3) and from -2x to +7.

Therefore, there are either 2 or 0 positive real zeros.

For negative real zeros, we look at the polynomial with x replaced by -x: f(-x)=8(-x)^(4)-7(-x)^(3)-4(-x)^(2)-2(-x)+7.

Simplifying, we get [tex]f(-x)=8x^4+7x^3-4x^2+2x+7[/tex]. There are no sign changes in this polynomial, so there are 0 negative real zeros.

In conclusion, Using Descartes's Rule of Signs, we can determine that there are either 2 or 0 positive real zeros and 0 negative real zeros of [tex]f(x)=8x^4-7x^3-4x^2-2x+7[/tex]

By taking the longer route, the amount of money Kelsey will save is $7.38.

To find out how much money Kelsey saves by taking the longer route, we need to calculate the total cost of each route and compare them.

For the shorter route, the total cost is the cost of gas plus the cost of tolls.
- The cost of gas is the distance traveled divided by the miles per gallon of the car, multiplied by the price of gas: (214 mi / 34.0 mpg)($3.29/gal) = $20.48
- The cost of tolls is $9.75
- So the total cost of the shorter route is $20.48 + $9.75 = $30.23

For the longer route, the total cost is just the cost of gas, since there are no tolls:
- The cost of gas is (236 mi / 34.0 mpg)($3.29/gal) = $22.85
- So the total cost of the longer route is $22.85

Now we can compare the two costs to find out how much money Kelsey saves by taking the longer route:
$30.23 (shorter route) - $22.85 (longer route) = $7.38

Therefore, Kelsey saves $7.38 by taking the longer route.

To divide two polynomials, P(x) and D(x), we can use either synthetic or long division. In this example, we'll use long division to divide P(x) by D(x) and express P in the form P(x)=D(x)⋅Q(x)+R(x).

First, we must make sure the degree of P(x) is greater than or equal to the degree of D(x). In this case, P(x)=-x^3-2x+6 and D(x)=x+1, so P(x) has a greater degree than D(x).

Next, we must write down P(x) and D(x) with the same degree. In this example, we can multiply D(x) by -x^2 to get -x^3+1. Then, P(x)=-x^3-2x+6 and D(x)=-x^3+1.

We can now start the long division process. First, we divide the leading coefficients, -1 and -1, so our quotient is 1. We then multiply the quotient by D(x), which gives us -x^3+1. We subtract this result from P(x), and the result is -2x+6.

Next, we divide the leading coefficients, -2 and -1, so our quotient is 2. We then multiply the quotient by D(x), which gives us -2x^2+2. We subtract this result from our previous result, -2x+6, and the result is 6.

Finally, we have reached the end of the long division process. Our quotient is Q(x)=2x+1 and our remainder is R(x)=6. Therefore, P(x)=D(x)⋅Q(x)+R(x), or -x^3-2x+6=(-x^3+1)⋅(2x+1)+6.

The volume of the right circular cone is approximately 1.6 cubic centimeters (rounding this answer to the nearest tenth of a cubic centimeter).

What is volume ?

Volume is a physical quantity that measures the amount of three-dimensional space that a substance or object occupies.

The volume of a right circular cone is given by the formula

[tex]V = (1/3)\pi r^2h[/tex] , where r is the radius of the base and h is the height of the cone. We are given the height of the cone, which is 14.9 cm. To find the radius of the base, we need to use the given circumference of the base, which is 2.9 cm.

The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius. We can rearrange this formula to solve for r, which gives us r = C/(2π). Plugging in the given circumference of 2.9 cm, we get:

r = 2.9/(2π) ≈ 0.461

Now, we can substitute the values of r and h into the formula for the volume of a cone and solve for V:

V = (1/3)π([tex]0.461^2[/tex])(14.9) ≈ 1.564 [tex]cm^3[/tex]

Rounding this answer to the nearest tenth of a cubic centimeter gives us a final volume of approximately [tex]1.6 cm^3[/tex]. Therefore, the volume of the right circular cone is approximately 1.6 cubic centimeters.

The annual payment for the loan is $48,867.89.

To find how much is the annual payment for the loan, we must first find the total cost of the land and the loan amount.

The total cost of the land is $4,100 × 215 = $881,500.

The down payment is 25% of the total cost, so the down payment is $881,500 × 0.25 = $220,375.

The loan amount is the total cost minus the down payment, so the loan amount is $881,500 - $220,375 = $661,125.

To find the annual payment, we can use the formula A = P(1 + r)^n / [(1 + r)^n - 1], where A is the annual payment, P is the loan amount, r is the annual interest rate (APR), and n is the number of years.

Plugging in the values, we get:

A = $661,125(1 + 0.0675)^20 / [(1 + 0.0675)^20 - 1]

A = $661,125(1.0675)^20 / [(1.0675)^20 - 1]

A = $661,125(3.0878) / (3.0878 - 1)

A = $2,040,756.55 / 2.0878

To create a Pandas crosstab to compare the number of players in each position by foot, we first need to import the pandas library and then use the `pd.crosstab()` function with the appropriate parameters.

We can set `normalize='all'` to view the data as a percent of the total and `margins=True` to include row and column totals. Here's how we can do it:

```python
import pandas as pd

# Create a crosstab with the desired parameters
crosstab = pd.crosstab(df['Position'], df['Foot'], normalize='all', margins=True)

# Print the crosstab
print(crosstab)
```

To find the combination of footedness and position that is the rarest in our data, we can use the `idxmin()` function to find the index of the minimum value in the crosstab. Here's how we can do it:

```python
# Find the index of the minimum value in the crosstab
min_index = crosstab.idxmin()

# Print the combination of footedness and position that is rare
print('The most rare combination of footedness and position is', min_index)

here length = n - 3 and width = 2 , then

A = 2(n - 3)

given A = 24 , then

2(n - 3) = 24

The final answer length of the other dimension of the garden is 9x units.

To find the length of the other dimension of the garden, we need to use the formula for the area of a rectangle:

Area = Length x Width

We are given the area and one dimension, so we can plug those values into the formula and solve for the other dimension:

[tex]81x^2-126x[/tex] = (9x-14)(Length)

To solve for the length, we need to divide both sides of the equation by (9x-14):

Length =[tex](81x^2-126x)/(9x-14)[/tex]

Now we can simplify the right side of the equation by factoring out a common factor of 9x:

Length = (9x)(9x-14)/(9x-14)

The (9x-14) terms cancel out, leaving us with:

Length = 9x

So the length of the other dimension of the garden is 9x units.

The perimeter of the inside of the track is approximately 354.36 meters.

What is the circumference?

In geometry, the circumference is the perimeter of a circle or ellipse.

To find the perimeter of the inside of the track, we need to find the length of the inside edge of the track and add it to twice the length of the semicircles at each end.

The inside edge of the track is formed by two parallel lines, each offset by a distance of 56 m from the outer edge. The length of this edge is equal to the length of the long straight edge minus twice the offset distance:

length of inside edge = 130 m - 2(56 m)

length of inside edge = 18 m

The length of each semicircle at each end is equal to half the circumference of a full circle with a radius equal to the width of the track (56 m). Therefore, the length of both semicircles is:

2 x (1/2 x 2π x 56 m) = 2π x 56 m

Adding the length of the inside edge to twice the length of the semicircles, we get:

perimeter of inside track = 18 m + 2π x 56 m

perimeter of inside track = 18 m + 112π m

the perimeter of the inside track ≈ 354.36 m (rounded to two decimal places)

Hence, the perimeter of the inside of the track is approximately 354.36 meters.

To determine if two functions, g(x) and h(x), are inverses of each other, we need to check if the composition of the two functions, g(h(x)) and h(g(x)), both result in x.

A. g(x) = 2 + 9 = 11, h(x) = 1/2x - 9

g(h(x)) = g(1/2x - 9) = 2 + 9 = 11

h(g(x)) = h(11) = 1/2(11) - 9 = -3/2

Since g(h(x)) ≠ x and h(g(x)) ≠ x, the functions g(x) and h(x) are not inverses of each other.

B. g(x) = x - 1, h(x) = x + 1

g(h(x)) = g(x + 1) = (x + 1) - 1 = x

h(g(x)) = h(x - 1) = (x - 1) + 1 = x

Since g(h(x)) = x and h(g(x)) = x, the functions g(x) and h(x) are inverses of each other.

C. g(x) = 3x - 6, h(x) = 1/3x + 2

g(h(x)) = g(1/3x + 2) = 3(1/3x + 2) - 6 = x

h(g(x)) = h(3x - 6) = 1/3(3x - 6) + 2 = x

Since g(h(x)) = x and h(g(x)) = x, the functions g(x) and h(x) are inverses of each other.

D. g(x) = 3x + 4, h(x) = x - 4/3

g(h(x)) = g(x - 4/3) = 3(x - 4/3) + 4 = 3x - 4

h(g(x)) = h(3x + 4) = (3x + 4) - 4/3 = 3x + 8/3
