Answer:
The constant of proportionality is 2.
Step-by-step explanation:
z^2 = kW where k is a constant.
When z = 4 , W = 8 so
4^2 = 8k
k = 4^2/8
= 16/8
= 2.
Answer:

Step-by-step explanation:
I'm assuming the question here is asking for f(x)
The first step would be to find the antiderivative of f'(x)

Apply the reverse power rule

Now solve for C when x = 9

Now substitute into the antiderivative

The lower left corner is the answer.
Angle 1 is congruent to angle 5 because they are alternate interior angles (assuming AB || DE)
They are on the inside of the parallel train tracks. By "train tracks" I mean the horizontal lines AB and DE. So they are considered interior angles. They are on alternate sides of the transversal AE. Angle 1 is on the right side while angle 5 is on the left side. These two facts are why they are considered alternate interior angles.
