Answer: x^2 - 10x + 14
Explanation:
f(g(x))
= f(x-3) Since g(x) = x-3
And f(x) = x^2 - 4x - 7
=> f(x-3) = (x-3)^2 - 4(x-3) - 7
=> f(x-3) = x^2 - 6x + 9 - 4x + 12 - 7
=> f(x-3) = x^2 - 10x + 14
Answer:
x = 27
Step-by-step explanation:
Length = 6x
Width = 1/3(6x) = 2x
Height = 1/2(6x) = 3x
6x × 2x × 3x = 36
972/36x = 27
x = 27
Answer:
20.36
Step-by-step explanation:
The area of the whole circle is pi*3.6^2 = 40.715 (rounded). However, the shaded portion is only half of the circle, since the arc is 180 degrees, so we divide this by 2 to get about 20.36.
