Answer:
-125
Step-by-step explanation:
Step 1: Find g(-1)
g(x) = -5x²
g(-1) = -5(-1)²
g(-1) = -5(1)
g(-1) = -5
Step 2: Find g(-5)
g(-5) = -5(-5)²
g(-5) = -5(25)
g(-5) = -125

The value should be used for n, the number of periods over which the loan is repaid in 60 periods.
We have to determine
In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the loan is repaid, as it appears in the following formula?
<h3>What formula is used to calculate the monthly payment?</h3>
The value of the monthly payment is given by;

Where,
- PV is the present value or the amount of the loan.
- i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.
- n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.
Therefore,
The value should be used for n, the number of periods over which the loan is repaid;
n = 6 years × 12 months/year = 60 months = 60 periods.
Hence, The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

So, since the initial fee is $50, and every hour is $15, if h is equal to hour, the equation would be like this:
50 + 15h = 110.
Then, if we want to get the answer, we need to solve the equation.
First we pass the 50 to the other side, like this:
15h = 110 - 50
15h = 60
Then we pass the 15 dividing like this:
h = 60/15
h = 4
And we get four!
So the answer is: 4.
Hope this helped! c:
