Answer:
(fog)(x) = 4x - 7
Step-by-step explanation:
f(x) = 2x-1 and g(x) = 2x-3;
(fog)(x) = f(g(x)
= f(2x - 3) = 2(2x - 3) - 1
= 4x - 6 - 1
= 4x - 7

Determine the coordinates of the centroid
Represent the coordinates with C.
C is calculated as follows:

Substitute values of x and y in the given equation



<em>The above is the coordinate of the centroid</em>
Answer:
C
Step-by-step explanation:
The length of arc AC (L) is calculated as
L = circumference of circle × fraction of circle
= 2πr × 
= 2π × 12 × 
= 2π × 5
= 10π ≈ 31.42 → C
