Gavin deposited money into his savings account that is compounded annually at an interest rate of 9%. Gavin thought the equivalent quarterly interest rate would be 2.25%. Is Gavin correct? If he is, explain why. If he is not correct, state what equivalent quarterly interest rate is and show how you got your answer. ( Please only answer if you know how to. Brainliest answer.

definition : When you are using quarterly interest rates instead of annual, you can find the appropriate rate by dividing the annual interest rate by the number of periods. For example, a 12 percent annual interest rate divided by four periods is a three percent quarterly interest rate.

so he uses 9% annually divided by 4 ( the year consist of four quarters )=2.25 which is correct.

9/4=2.25

Step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
