Answer:
9%
Step-by-step explanation:
You are going to want to use a modified compound interest formula, as shown below. This version of the compound interest formula is what you use to solve for the interest rate.
<em>r = interest rate (decimal)</em>
<em>n = numbers of times compounded (annually)</em>
<em>A = total amount</em>
<em>P = principal amount</em>
<em>t = time (years)</em>
Now, lets plug in the values:
r = 9% interest rate
(x-7)² = 36
The square root of both is √(x-7)² =√6²
x-7 = + or - 6
x-7 = 6 , then x = 13
x-7 = -6, then x = 1
So the values of x are 13 or 1
Answer:
C) 24√2
Step-by-step explanation:
The distance between the points is the radius of the circle. Use distance formula:
d² = (x₂ − x₁)² + (y₂ − y₁)²
d² = (5 − 2)² + (2 − 5)²
d² = 3² + 3²
d = 3√2
The radius of the circle is 3√2. The diameter of the circle is 6√2, so the side length of the square is 6√2. Therefore, the perimeter is 24√2.
