Prove that the square of an odd number is always 1 more than a multiple of 4

By these examples you are able to see that the square of an odd number is always 1 more than a multiple of 4.

Step-by-step explanation:

For examples,

Let's consider squares of 3, 11, 25, 37 and 131.

8 is a multiple of 4, and 9 is more than 8.

120 is a multiple of 4 and 121 is one more than it.

624 is a multiple of 4 and 625 is one more than it.

1368 is a multiple of 4 and 1369 is one more than 1368.

17160 is a multiple of 4.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
