Mekhanik [1.2K]2 years ago

Answer: x = 11

Step-by-step explanation:

Complementary angles = 90*

Set the two equations equal to 90. Solve

4x + 6 + 4x - 4 = 90

8x +2 = 90

8x = 88

x = 11

Plug it in to see if it makes equation true

4 (11) + 6 + 4 (11) - 4 = 90

44 + 6 + 44 - 4 = 90

50 + 40 = 90

90 = 90

Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. The account balance after a period of 5 years will be $1.63634×10²⁰.

<h3>What is compound interest?</h3>

Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter.

A = P(1 + \frac{r}{n})^{nt}

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Given the principal amount is $12,385, the rate of interest is 7.5%, and the time period is daily. Therefore, the amount can be written as,

A = P(1 + \frac{r}{n})^{nt}\\\\A = \$12,385(1 + \frac{7.5}{365})^{(365 \times 5)}\\\\A = \$1.63634 \times 10^{20}

Hence, the account balance after a period of 5 years will be $1.63634×10²⁰.
