Answer:
<h2>(k ∘ p)(x) = 2x² - 16x + 25</h2>
Step-by-step explanation:
k(x) = 2x² - 7
p(x) = x - 4
To find (k ∘ p)(x) substitute p(x) into k(x),
that's replace any x in k(x) by p(x)
We have
(k ∘ p)(x) = 2(x - 4)² - 7
Expand
(k ∘ p)(x) = 2( x² - 8x + 16) - 7
= 2x² - 16x + 32 - 7
Simplify
We have the final answer as
<h3>(k ∘ p)(x) = 2x² - 16x + 25</h3>
Hope this helps you
Answer:
The volume of cube is increasing at a rate 7.5 cubic meter per hour.
Step-by-step explanation:
We are given the following in the question:
Surface area of cube = 24 square meters.
Let l be the edge of cube.
Surface area of cube =
Thus, at that instant the edge of cube is 2 meters.
We have to find the rate of change in volume.
Volume of cube =
Rate of change of volume =
Thus, the volume of cube is increasing at a rate 7.5 cubic meter per hour.
X=6
g(f(x))=g(f(18))
=g(5/6*18 +5)
=g(20)
=(5*20)+6
=106
You list the step by step and you're done.
Do you have an example??
