For number 9. its 34 × 65 = 65 × 34.. So that means its communicative property
For the equation you gave, which is y = a(b)^x, increasing the b value would increase how much more the y value would increase/decrease (depending if x is > or < 0). Please view the image attached!

Given:
- Function f(x) = 2|x + 3| - 2
Find a function g which is a horizontal shrink by a factor of 1/3 of f(x).
Horizontal shrink by a factor of k is:
Apply this to the given function:
- g(x) = f(x : 1/3) = f(3x) = 2|3x + 3| - 2 = 6|x + 1| - 2
Answer:
C = 6π in
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
the area (A) of a circle is calculated as
A = πr²
given A = 9π , then
πr² = 9π ( divide both sides by π )
r² = 9 ( take square root of both sides )
r = = 3
then
C = 2π × 3 = 6π in
