1. the APR for this loan is 6%.

2.  the unearned interest is $118.83.

3.  the monthly payment necessary to amortize the $80,000 mortgage at 6% annual interest for 25 years is $506.69.

APR = (finance charge / loan amount) / number of years * 100%

In this scenario, the loan amount is $2400 and the finance charge is $288. Since it's a two-year loan, the number of years is 2

APR = (288 / 2400) / 2 * 100%

APR = 0.06 * 100%

APR = 6%

b.

Number of payments = 4 years * 12 months/year = 48

If the loan is paid off in 3 years instead of 4 years, the number of payments made is:

Number of payments made = 3 years * 12 months/year = 36

Substituting these values into the formula, we get:

Unearned interest = (1426 / 48) * (48 - 36)

Unearned interest = $118.83

3.

To find the monthly payment necessary to amortize a mortgage, we need to use the formula:

M = P * (r / (1 - (1 + r)^(-n)))

where M is the monthly payment, P is the principal (loan amount), r is the monthly interest rate, and n is the total number of payments (in months).

In this scenario, the loan amount is $80,000, the annual interest rate is 6%, and the loan term is 25 years. To find the monthly interest rate, we divide the annual interest rate by 12 (since there are 12 months in a year):

Monthly interest rate = 6% / 12 = 0.005

To find the total number of payments, we multiply the number of years by 12:

Number of payments = 25 years * 12 months/year = 300

Substituting these values into the formula, we get:

M = 80000 * (0.005 / (1 - (1 + 0.005)^(-300)))

M ≈ $506.69

Thus, the value of b over a for the given logarithmic function is obtained as: b/a = 1 + √2.

The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent with which b must be raised in order to obtain a number x is the logarithm of x to the base b.

A base must still be raised to a certain exponent or power, or logarithm, in order to produce a specific number. If bˣ = n, then x is the logarithm of n to the base b, which is expressed mathematically as x = logb n.

Given that:

log9(a) = log15(b) = log25(a + 2b)

Let ,  log9(a) = log15(b) = log25(a + 2b) = x

Then,

log9(a) = x (taking antilog)

log3²(a) = x

a = 3²ˣ

log15(b) = x  (taking antilog)

log(3*5)(b) = x

b = 3ˣ.5ˣ

log25(a + 2b) = x   (taking antilog)

log5²(a + 2b) = x

a + 2b = 5²ˣ

Now,

b²/a = a + 2b

(b/a)² = 1 + 2*(b/a)

If t = b/a, then t² - 2t -1 = 0

On factorization:

t = 1 ± √2 ( a and b are positive integer)

b/a = 1 + √2

Thus, the value of b over a for the given logarithmic function is obtained as: b/a = 1 + √2.

There is a 0.9830, or 98.30%, probability that the mean clock life will exceed 12.5 years.

Probability is a metric used to express the possibility or chance that a particular event will occur.

Probabilities can be expressed as fractions from 0 to 1, as well as percentages from 0% to 100%.

Probability is simply the possibility that something will happen. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several.

The study of events that fit into a probability distribution is known as statistics.

So, the likelihood that the average clock life would exceed 12.5 years:

This is the p-value of Z when X = 12.5 subtracted by 1.

So,

Z = X - μ/σ

Z = 12.5 - 14/.07071

Z = -2.12

Z = The pvalue for -2.12 is 0.0170.

Rates of first and second mechanics are 75 and 60 per hour respectively.

A mathematical statement or relation between two or more numeric values, variable and mathematical operations via equal sign is called an Equation.

Elimination method is a kind of method to solve simultaneous equations in two variables. In elimination method we compare coefficient of one of two variables and in next step we eliminate that variable using addition or subtraction and form another relation with only one variable and find the value for that one variable and then substituting that value initial equation we can get the value of another variable.

Let the rate of first mechanic and second mechanic be x and y per hour respectively.

Sum of the two rates is 135 per hour. So the suitable equation will be,

x+y = 135 ............... (i)

Since they charged together 1650 after working 10 hours by first and 15 hours by second mechanics. So the suitable equation this time will be,

10x+15y = 1650

5(2x+3y) = 1650

2x+3y = 1650/5

2x+3y = 330 ............... (ii)

Multiplying 2 with equation (i) and then subtracting it from equation (ii) we get,

(2x+3y) - 2(x+y) = 330 - 2*135

2x+3y-2x-2y = 330-270

y = 60

Substituting y=60 in equation (i) we get,

x+60 = 135

x = 135-60 = 75

Hence, the rates charged per hour are 75 and 60 per hour respectively.

The length of the rectangle is 10 inches and the width is 4 inches.

What is the area of the rectangle?

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

Let's assume that the width of the rectangle is "x" inches.

From the given information, we can write an equation for the length "L" in terms of the width "x":

L = 2x + 2

We also know that the area of the rectangle is 40 square inches:

A = L * x = 40

Substituting the expression for "L" in terms of "x" into the area equation, we get:

(2x + 2) * x = 40

Expanding the left-hand side of the equation and simplifying, we get:

2x² + 2x - 40 = 0

Dividing both sides by 2, we get:

x² + x - 20 = 0

This is a quadratic equation that can be factored:

(x + 5)(x - 4) = 0

The solutions are x = -5 and x = 4. Since the width of the rectangle cannot be negative, the only valid solution is:

x = 4

Substituting this value for "x" into the equation for "L", we get:

L = 2x + 2 = 2(4) + 2 = 10

Therefore, the length of the rectangle is 10 inches and the width is 4 inches.

Answer:

If (x-1) is a factor of the polynomial f(x) = 4x² - 4x² - x - K, then we know that (x-1) divides evenly into the polynomial, which means that the polynomial can be written as:

f(x) = (x-1)(ax + b)

where a and b are constants that we need to determine. We can use the distributive property to expand this expression and equate it with the original polynomial:

f(x) = (x-1)(ax + b) = 4x² - 4x - K

Expanding the left side of the equation, we get:

ax² + bx - ax - b = ax² - (a-b)x - b = 4x² - 4x - K

Now we can equate the coefficients of the like terms on both sides of the equation.

The coefficient of x^2 on the left side is a, and on the right side it is 4. Therefore, we have:

a = 4

The coefficient of x on the left side is b - a, and on the right side it is -4. Therefore, we have:

b - a = -4

Substituting a=4, we get:

b - 4 = -4

Solving for b, we get:

b = 0

So the polynomial can be written as:

f(x) = (x-1)(4x + 0) = 4x² - 4x

Therefore, K = 0.

To find the roots of the equation, we need to set f(x) = 0 and solve for x:

4x² - 4x = 0

Factor out 4x:

4x(x - 1) = 0

So the roots of the equation are x = 0 and x = 1.

Answer: 601 meters

Step-by-step explanation:

First, let's find the midpoint between the "Falcon Flyer" and the "Sprinter".

The x-coordinate of the midpoint is (50 + 400)/2 = 225.

The y-coordinate of the midpoint is (300 + 550)/2 = 425.

So the midpoint is (225, 425).

Now we need to find the distance between the midpoint and the "Air Rider". Using the distance formula:

d = sqrt[(800 - 225)^2 + (250 - 425)^2]

d = sqrt[(575)^2 + (-175)^2]

d = sqrt[330625 + 30625]

d = sqrt(361250)

d ≈ 601.041

The total amount Debra ended up paying for the equipment was $28,541.60 and the amount of interest Debra paid on the loan was $14,041.60

(a) To find the total amount Debra ended up paying for the equipment (including the down payment and monthly payments), we need to add the down payment to the total amount of the loan, and then add the total amount of the monthly payments made over the two years.

Total amount of the loan = $14,500 - $1,300 (down payment) = $13,200

Total amount paid = Down payment + Total amount of the loan + Total amount of monthly payments

Total amount paid = $1,300 + $13,200 + ($585.04 x 24) [since there are 24 monthly payments in 2 years]

Total amount paid = $1,300 + $13,200 + $14,041.60

Total amount paid = $28,541.60

Therefore, the total amount Debra ended up paying for the equipment (including the down payment and monthly payments) was $28,541.60.

(b) To find the amount of interest paid on the loan, we need to subtract the total amount borrowed from the total amount paid, and then subtract the down payment. This will give us the total amount of interest paid over the two years.

Total interest paid = Total amount paid - Total amount borrowed - Down payment

Total interest paid = $28,541.60 - $13,200 - $1,300

Total interest paid = $14,041.60

Therefore, the amount of interest Debra paid on the loan was $14,041.60.

Plan A lasts for 2/7 hours or approximately 17.14 minutes, and Plan B lasts for 9/7 hours or approximately 1 hour and 17.14 minutes.

In algebra, the definition of an equation in its simplest form is a mathematical statement that shows that two mathematical expressions are equal. For example, 3x 5 = 14 is an equation where 3x 5 and 14 are two expressions separated by an equal sign.

Let's say plan A takes x hours and plan B takes y hours.

Based on the given data, we can create two equations:

Monday: 6x + 5y = 7

Tuesday: 2x + 3y = 3

We can solve this system of equations by elimination or substitution.

Eliminating, we can multiply the second equation by two and subtract it from the first equation:

(6x + 5 y) - 2 (2x + 3y) = 7 - 2 (3)

Simplifying this, we get:

2x - y = 1

Using substitution, we can solve an equation in one variable and replace it with another equation:

From the first equation we can solve for x:  

6x + 5y = 7

6x = 7-5 years

x = (7-5 ​​years) / 6

Substituting this into the second equation, we get:

2 ((7-5 years) / 6) + 3 y = 3

Simplifying this, we get:

7 y = 9

y = 9/7

Now that we know y, we can substitute it back into both equations to solve for x:

6 x + 5 (9/7) = 7

Simplifying this, we get:

x = 2/7

|c| = sqrt((-9)^2 + (-9)^2) = sqrt(162) = 9sqrt(2)

To find the direction angle of c, we can use the formula:

theta = atan(c2 / c1)

where theta is the angle between the positive x-axis and the vector c. In this case, we have:

theta = atan((-9) / (-9)) = atan(1) = pi/4

So the direction angle of c is pi/4.

Therefore, the magnitude of c is 9sqrt(2) and the direction angle of c is pi/4.

The correct option is C. mean, that is Mr. Greene should use the mean temperature, which is 77.86°F.

In mathematics, the mean value is a measure of central tendency of a set of numbers. It is also known as the arithmetic mean and is found by adding all the numbers in a set and dividing the sum by the total number of values. The mean is commonly used to represent the typical or average value of a set of data. It is a useful tool in statistics and other branches of mathematics for analyzing data and making predictions. The mean value can be affected by outliers or extreme values in a set of data, which can skew the results. However, in many cases, the mean provides a reliable and useful measure of central tendency.

Mr. Greene should use the mean temperature, which is 77.86°F, to summarize the temperatures for each day. The mean is a good measure of central tendency when the data set is approximately symmetric and has no significant outliers, which appears to be the case here. Additionally, using the mean will provide a single number that is representative of the entire data set. The interquartile range and mean absolute deviation are measures of spread and do not provide a summary of the temperatures for each day, and the maximum temperature is just one value and may not be representative of the entire data set.
