$482.11 in interest
Use the compound amount formula. Calculate the compound amount and then subtract the principle to find the amount of interest earned.
A = P(1 + r)^t, where r is the interest rate as a decimal fraction
This becomes:
A = $575(1 + 0.07)^9, or A = $1057.11.
Subtracting the principal: A - P: $1057.11 - $575 = $402.11
Answer:
Step-by-step explanation:

X² - 16x =23
16/2= 8; 8²=64 add 64 to both sides of the equation
x² - 16x + 64 = 23 + 64
the answer is D.
Answer:
<u>b = -4, 0</u>
Step-by-step explanation:
<u>Given</u> :
<u>Take b as a common factor.</u>
<u>Solutions</u>
- b = 0
- b + 4 = 0 ⇒ b = -4
- <u>b = -4, 0</u>
I did this in school: it would be A, C, and D
