Answer:

See explanation

Step-by-step explanation:

The question is incomplete, as the function is not given. So, I will make an assumption.

A quadratic function is represented as:

f(x) = ax^2 + bx + c

If a > 0, then the function has a minimum x value

E.g. f(x) = 4x^2 - 5x + 8 ------ 4 > 0

Else, then the function has a maximum x value

E.g. f(x)= -4x^2 -5x + 8 ---- -4 < 0

The maximum or minimum x value is calculated using:

x = -\frac{b}{2a}

For instance, the maximum of f(x)= -4x^2 -5x + 8 is:

x = -\frac{-5}{2*-4}

x = -\frac{5}{8}

So, the maximum of the function is:

f(x)= -4x^2 -5x + 8

f(-\frac{5}{8}) = -4 * (-\frac{5}{8})^2 - 5 *(-\frac{5}{8}) +8

f(-\frac{5}{8}) = 9.5625

P=rt+0.16s  

365=20r+0.16(1500)

365=20r+240

125=20r

r=6.25

So Piper makes $6.25 an hour.
