452.16 = 3.1416 r^2
r^2 = 452.16 / 3.1416
r^2 = 143.93
r = 11.997
C = 2 (3.1416) (12) =75.38 m
8x - 4y = -12
4y = 8x + 12
y = 8/4 x + 12/4
y = 2x + 3
When x = -3,
y = 2(-3) + 3 = -6 + 3 = -3
When x = -1,
y = 2(-1) + 3 = -2 + 3 = 1
When x = 1,
y = 2(1) + 3 = 2 + 3 = 5

Answer: 25
Step-by-step explanation:
Plug in x to the expression.

When there is the same base of exponents is being multiplied the exponents add together and the base stays the same.
So this simplifies to,
.
This then solves to 25.
Answer: The common difference is 8
Step-by-step explanation:
First Use the formula for the second to generate the first two numbers.
= 2^3n-2
Put in 1 for the first term and you will get 2 and the second term is 16 and to get from 2 to 16 you will multiply by 8.
