13. $15,000 is invested in an account that yeilds 5% interest per year. After how many years will the account be worth $91,221.04 if the interest is compounded yearly?

The correct answer is 37 years.

Step-by-step explanation:

Principal (P) invested is $15000

Rate of interest (r) per year is 5% compounded yearly.

Amount (A) of the principal is $91221.04.

Let the principal is invested for x years (t).

According to the problem,

A = P +

⇒ 91221.04 = 15000 ×

⇒ 6.08140267 =

⇒ x = 37

Thus the principal is supposed to be invested for 37 years for it to yield that amount.

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
