Answer:
For question 20.
Pamela: y = 20h
y = 20(40)= $800
John: y = 65p
y = 65(11)=<u> $675</u>
<u />
And for question 21.
660,000*63%=660,000*0.63=415,800
There are currently <u>415,800</u> gallons of water in the pool.

Answer: c
Step-by-step explanation:
Use pythagorean theorem,
x = 9.75
we have
Since the leading coefficient is negative, the function has a maximum
Let
y=f(x)
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
the vertex is the point
therefore
<u>the answer is the option </u>
A. Maximum at (1, 1)
