Question

HELP PLEASEEEEE. I'm honestly horrible at math and really need help figuring this out.

Answer 1

The answer c is correct

Answer 2

Nevermind, you can solve it, wait

You need to take the derivative of the function

h=0.01x^2-x+27

derivative by x:
0=0.02x-1
1=0.02x
0.02x=1
x=1/0.02=50

Now plug x into the first equation to get h
h=0.01x^2-x+27=0.01*50*50-50+27=25-50+27=2 inches
