Answer: The product of (-4)(-8) is 32. Multiply two negatives makes it positive. So just think of it as 4 times 8. Which is 32.
Ex: you can do 5-3 by putting a dot on the five and looping back 3 spaces. Hope it helps!
The number of periods over which interest is calculated on the loan.
We have to determine
The following formula is used to calculate the monthly payment on a personal loan.
<h3>What is the formula used to calculate monthly payments?</h3>
The formula used to calculate monthly payments are as follows;

Where,
1. PV is the present value or the amount of the loan.
2. 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.
3. 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.
Hence, the number of periods over which interest is calculated on the loan.

Answer:
see explanation
Step-by-step explanation:
(a)
Given y is inversely proportional to x² then the equation relating them is
y =
← k is the constant of variation
To find k use any ordered pair from the table.
Using (1, 4 ) , then
4 =
=
( multiply both sides by 1
4 = k
y =
← equation of variation
(b)
When y = 25 , then
25 =
( multiply both sides by x² )
25x² = 4 ( divide both sides by 25 )
x² =
( take the square root of both sides )
x = ±
= ± 
Since x > 0 then x =
