Nathan is opening a savings account that has a 10% simple interest rate. He deposits $75 in the account. After 5 years, he will have $112.50 in his account. How many more dollars would Nathan earn after 5 years with a 10% compounded interest rate?

Dollars earned after 5 years = $45.79

Step-by-step explanation:

Given that:

Initial money deposited in account = $75

Time for which the money is deposited = 5 years

Interest rate = 10%

Nature of interest = Simple Interest

Amount after 5 years = $112.50

To find:

Total money earned after 5 years if the interest is compounded ?

Solution:

Formula for amount if the interest is compounded annually:

Where P is the principal amount (initial money)

R is the rate of interest

T is the time

Putting all the values:

Total more money earned or the interest after the compounding nature =

= $120.79 - $75 = $45.79

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer: i wpould go with c
