The following table shows a portion of a five-year amortization schedule.
A 5-year amortization schedule.
Loan amount or principal: 10,900 dollars.
The interest rate on loan: 10. 95 percent.
The table will be
Month Payment Principal Interest Balance
15 236.72 155.87 80.85 8704.27
16 236.72 157.29 79.43 8546.98
17 236.72 158.73 77.99 8388.25
18 236.72 160.18 76.54 8228.07
19 236.72 161.64 75.08 80.66.43
20 236.72 163.11 73.61 7903.32
Total payment = 6 × 236.72 = $ 1420.32
Total interest = 80.85 + 79.43 + 77.99 + 76.56 + 75.08 + 73.61
Total interest = $ 463.38
Then the percentage will be

Answer:
Rate of change = -1
Step-by-step explanation:
Given:
f(x) = -½(x + 2)² + 5
Required:
Average rate of change from x = -3 to x = 1
Solution:
Rate of change =
Where,
a = -3,
f(a) = f(-3) = -½(-3 + 2)² + 5 = -½(-1)² + 5 = 4.5
b = 1,
f(b) = f(1) = -½(1 + 2)² + 5 = -½(9) + 5 = 0.5
Plug in the values into the formula:
Rate of change =
Rate of change =
Rate of change = -1
