Answer 1

Step-by-step explanation:

Given:

Focus above the ground = 40 ft

Recall the below equation of a parabola;

`\begin{gathered} (x-h)^2=4a(y-k)^ \\ \end{gathered}`

Given that the focus is 40 ft above the ground, then h = 0, so we'll have;

`\begin{gathered} (x-0)^2=4a(y-k) \\ y=(x^2)/(4a+k) \end{gathered}`

Note that the focus point is (h, a + k) where a + k =
