Answer:
21
Step-by-step explanation:
Given the following expressions
f(x) = x³-2x
g(x) =-x-2
We are to find (fog)(-5)
fog = f(g(x))
f(g(x)) = f(-x-2)
Replace x with -x-2 in f(x)
f(-x-2) = (-x-2)³-2(-x-2)
f(-x-2) = (-x-2)³+2x+4
fog = (-x-2)³+2x+4
Substitute x = -5 into the result
fog(-5) = (-x-2)³+2x+4
fog(-5) = (-(-5)-2)³+2(-5)+4
fog(-5) = (5-2)³-10+4
fog(-5) = 3³-6
fog(-5) = 27-6
fog(-5) = 21
Hence the required result of the composite function is 21
We have two triangles with base 9ft and height 12.3ft and two triangles with base 11ft and height 11.9ft.
The formula of an area of a triangle:
Triangle #1:
b = 9ft and h = 12.3ft. Substitute:
Triangle #2:
b = 11ft and h = 11.9ft. Substitute:
The Lateral Area:
<h3>Answer: B. 241.6 ft².</h3>
Answer:
-11 =d
Step-by-step explanation:
22/d = -2
Multiply each side by d
22/d *d = -2*d
22 = -2d
Divide each side by -2
22/-2 = -2d/2
-11 =d
