Answer:
4(6) + 3 = 24 + 3 = 27
Step-by-step explanation:
The general form for a parabolic dish is:
y=x^2/(4f), where f=focus' y coordinate when x=0
So if you are given the equation:
8y=x^2, you need only to rearrange it to the form y=x^2/(4f)
y=x^2/8
Since 8=4f, f=2 inches and the focal point of course (0,2)
