8. Alvin purchased $1,300,000 worth of videogame set and made a $150,000 down payment. He agreed to pay the balance by making equal payments at the end of each month for 20 years. What is the size of the monthly payment if the interest charged is 16% compounded quarterly?
Answers
We have a purchase of $1,300,000.
The downpayment is $150,000 and the rest is financed.
We can calculate the amount that is owed as:
\(\begin{gathered} C=1,300,000-150,000 \\ C=1,150,000 \end{gathered}\)This amount will be paid in equal amounts, monthly for 20 years.
The interest rate is 16% compounded quarterly.
We have to start by converting the interest rate in a monthly-compounded equivalent rate.
A rate of 16% compounded quarterly (m=3) will be equivalent to a monthly rate r. We can calculate r as:
\(\begin{gathered} (1+r)^{12}=(1+\frac{0.16}{3})^3 \\ (1+r)^4=1+\frac{0.16}{3} \\ (1+r)^4\approx1+0.05333 \\ 1+r\approx1.0533^{\frac{1}{4}} \\ r\approx1.013-1 \\ r\approx0.013 \end{gathered}\)We then can calculate the payments as an annuity with r = 0.013 and 20*12 = 240 payments.
We can calculate the amount he will pay each month as:
\(\begin{gathered} P=\frac{r\cdot PV}{1-(1+r)^{-n}} \\ P=\frac{0.013\cdot1150000}{1-(1+0.013)^{-240}} \\ P=\frac{14950}{1-1.013^{-240}} \\ P=\frac{14950}{1-0.045} \\ P=\frac{14950}{0.955} \\ P=15654.45 \end{gathered}\)Answer: the monthly payment is approximately $15654.45.

Linda got a prepaid debit card with $20 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 14 cents per yard. If after that purchase there was $17. 06 left on the card, how many yards of ribbon did Linda buy?
Answers
Therefore, Linda bought 21 yards of ribbon. Hence, Linda bought 94 yards of ribbon.
The number of yards of ribbon Linda bought, we need to calculate the difference between the initial balance on the card and the remaining balance after the purchase.
The initial balance on the card was $20. To find the amount spent on ribbon, we subtract the remaining balance ($17.06) from the initial balance. $20 - $17.06 = $2.94
Now, we need to determine how many yards of ribbon Linda could purchase with $2.94, given that the price of the ribbon is 14 cents per yard.
To find the number of yards, we divide the total amount spent ($2.94) by the price per yard (14 cents): $2.94 ÷ $0.14 = 21
Therefore, Linda bought 21 yards of ribbon.
Hence, Linda bought 94 yards of ribbon.

labor (number of workers) output (units) marginal product (units) 0 0 – 1 300 2 500 3 600 4 650 refer to table 13-2. what is the marginal product of the first worker?
Answers
The marginal product of the first worker is 300 units. This is because the output increases from 0 units to 300 units from adding the first worker.
This is derived by subtracting the first worker's output (300 units) from the output of no workers (0 units). The output that one more worker would bring to the overall output of a certain industrial process is known as the marginal product.
The marginal product of the first worker in this instance is 300 units, which are added to the output. The output of the second worker (500 units) differs from the output of the first worker by 500 units, which is the marginal product of the next worker (300 units).

find the taylor polynomial t3(x) for the function f centered at the number a. f(x) = xe−4x, a = 0
Answers
To find the Taylor polynomial t3(x) for the function f(x) = xe^(-4x) centered at a = 0, we need to find the first four derivatives of f(x) at x = 0, evaluate them at x = 0, and use them to construct the polynomial.
The first four derivatives of f(x) are:
f'(x) = e^(-4x) - 4xe^(-4x)
f''(x) = 16xe^(-4x) - 8e^(-4x)
f'''(x) = -64xe^(-4x) + 48e^(-4x)
f''''(x) = 256xe^(-4x) - 256e^(-4x)
Evaluating these derivatives at x = 0, we get:
f(0) = 0
f'(0) = 1
f''(0) = -8
f'''(0) = 48
f''''(0) = -256
Using these values, we can construct the third-degree Taylor polynomial t3(x) for f(x) centered at x = 0:
t3(x) = f(0) + f'(0)x + f''(0)x^2/2! + f'''(0)x^3/3!
t3(x) = 0 + 1x - 8x^2/2 + 48x^3/3!
t3(x) = x - 4x^2 + 16x^3/3
Therefore, the third-degree Taylor polynomial for the function f(x) = xe^(-4x) centered at a = 0 is t3(x) = x - 4x^2 + 16x^3/3.

Two functions are represented below what is the difference in rate of change between functional a function A and function B. Be sure to include the rate of change of each function in your question answer(8.F.2)
Answers
The difference in the rate of change between Function A and function B is -2.
The difference in the rate of change between function A and function B, we first need to identify the rate of change for each function. The rate of change, also known as the slope, represents how much the dependent variable (y) changes for every unit increase in the independent variable (x).
Let's assume function A is represented by the equation y = 2x + 3, and function B is represented by the equation y = 4x - 1.
For function A: y = 2x + 3, the coefficient of x is 2, indicating that for every unit increase in x, y increases by 2. Therefore, the rate of change for function A is 2.
For function B: y = 4x - 1, the coefficient of x is 4, indicating that for every unit increase in x, y increases by 4. Therefore, the rate of change for function B is 4.
Now, to find the difference in the rate of change between function A and function B, we subtract the rate of change of function B from the rate of change of function A:
Difference in rate of change = Rate of change of function A - Rate of change of function B
= 2 - 4
= -2
The difference in the rate of change between function A and function B is -2. This means that for every unit increase in x, function B increases at a rate that is 2 units greater than function A. It indicates that function B has a steeper slope and a faster rate of change compared to function A.
In summary, the difference in the rate of change between function A and function B is -2.

Answer:
x+(x-1.25)+\(\frac {1}{2}x\)=4.27

A manufacturing company produces electric insulators. If the insulators break when in use, a short circuit is likely to occur. To test the strength of the insulators, destructive testing is carried out to determine how much force is required to break the insulators. Force is measured by observing how many pounds must be applied to an insulator before it breaks. A samole of 11 insulators is collected where the strengths are as follows (in thousands): 1.6 12 1.1 12 14 1.6 12 15 1.6 18 14 Compute and list the five number summary Construct a boxplot. Are the data skewed? If so, how? What can you conclude about the strength of the insulators if the target given by the company is set as *75% of the insulators should not be broken before applying 1.6 thousand of pi ounds?" Explain
Answers
The five-number summary of the strengths of the insulators is
Minimum: 1.1 First Quartile (Q1): 1.6 Median (Q2): 12 Third Quartile (Q3): 14 Maximum: 18
we can use the five-number summary. The boxplot visually represents the distribution of the data. The box represents the interquartile range (IQR), which is the range between Q1 and Q3. The line inside the box represents the median (Q2). The whiskers extend from the box to the minimum and maximum values, excluding any outliers.
Regarding the skewness of the data, we can observe that the majority of the data points are clustered around the lower values (1.1, 1.6, 12), while there are a few data points that are much higher (14, 15, 18). This indicates that the data is skewed to the right, or positively skewed. The presence of these higher values causes the mean to be pulled towards the right.
Based on the target set by the company, which states that 75% of the insulators should not be broken before applying 1.6 thousand pounds, we can conclude that the majority of the insulators meet the target strength. The first quartile (Q1) value of 1.6 represents the threshold, and since it falls within the lower range of the data, it means that 75% of the insulators have a strength that is equal to or greater than the target. However, there are some outliers (14, 15, 18) that surpass this target, indicating a few insulators with exceptionally high strength. Overall, the majority of the insulators meet the company's target requirement.

On a trip from Louisiana to Florida, your family wants to travel at least 420 miles in 8 hours of driving. Write and solve an inequality to find what your average speed must be.
Answers
The required the average speed must be at least 52.5 mph to travel 420 miles in 8 hours.
What is inequality?A difference between two values indicates whether one is smaller, larger, or simply not equal to the other. A B indicates that a and b are not equal. When a b, an is said to be less than b. A > B indicates that an is superior to b. These two constitute tight inequity.
According to question:Let the average speed of the trip "x" in miles per hour. To find out what the average speed must be, we need to write an inequality based on the given information and then solve it.
The formula for distance, speed, and time is:
distance = speed * time
So, the distance traveled can be written as:
distance = x * 8 hours
And the inequality based on the given information that the distance must be at least 420 miles is:
x * 8 ≥ 420
To solve for x, we need to divide both sides of the inequality by 8:
x ≥ 420 / 8
x ≥ 52.5
So, the average speed must be at least 52.5 mph to travel 420 miles in 8 hours.
