Cressida decided to save a part of her income in a savings account that compounds interest every four months. her account balance after t years can be given by the following expression.

3,545(1.045)3t

what does the value 3 in the exponent represent?

a.
the amount saved each year
b.
the number of times the account compounds interest
c.
the growth factor that reveals the rate at which the account balance increases
d.
the initial amount invested

B. the number of times (per year) the account compounds interest

Step-by-step explanation:

The given expression has no exponent. We assume you intend ...

balance = 3,545·1.045^(3t)

This expression for the account balance suggests Cressida invested 3,545 into an account paying interest at an annual rate of 13.5%, compounded 3 times per year. The 3 multiplying the number of years is the number of times interest is compounded per year.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
