A football is thrown to a reciver 40 yards away. Using the quadratic formula
y = -0.025x(Squared) + x + 5 determine:
a) How many yards from the quarterback does the football reach it's maximum height and
b) What is the footballs' height at that distance.

A football is thrown to a reciver 40 yards away. Using the quadratic formula

y = -0.025x(Squared) + x + 5 determine:

Why not use ^ for powers like so: -.025x^2

Instead of writing out the word 'squared'?

After all, that is what SHIFT 6 is for.

y=\frac{-25}{1000}x^{2}+x+5


a) How many yards from the quarterback does the football reach it's maximum height

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


b) What is the footballs' height at that distance.

Just use y=c-\frac{b^{2}}{4a}

From the graph, I made the assumption it is thrown from ground level. That may not be the case. It is probably thrown from a height of 5 feet at (0,5).
