The total amount of money in a savings account after t years is given by the function a=1000(1.031)^t . how could this function be rewritten to identify the monthly interest rate? what is the approximate monthly interest rate?

A = 1000 ( 1 + .031/12) ^(12t)

The approximate monthly interest rate is .2583 percent

Step-by-step explanation:

A=1000(1.031)^t

The formula for compound interest is given by

A = P(1 + r/n) ^ (nt)    

Take 1.031 and subtract 1

.031 is the yearly rate in decimal form

A = 1000 ( 1 + .031/12) ^(12t)

Change to a percent = 3.1 %

Divide by 12

3.1/12 = .2583333333(repeating)  %

This would be the monthly rate

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
