Answer:
x = 2.
Step-by-step explanation:
3^2x = 9^(3x - 4)
9^3x-4 = 3^2x
(3^2)^(3x-4) = 3 ^2x
3^6x-8 = 3^2x
6x - 8 = 2x
4x = 8
x = 2 (answer).
Just by comparing the plots of f(x) and g(x), it's clear that g(x) is just some positive scalar multiple of f(x), so that for some constant k, we have
g(x) = k • f(x) = kx² = (√k x)²
The plot of the transformed function g(x) = (√k x)² passes through the point (1, 4), which means
g(1) = (√k • 1)² = 4
and it follows that k = 4. So g(x) = 4x² = (2x)² and B is the correct choice.
Answer:
≈39.27 units
Step-by-step explanation:
To find the area of a semi circle, you use the formula for finding the area of a circle, which is 
, and then you divide that by 2 since it is half of a circle.
In this case, 
≈ 78.54
= 39.27
