Greg is practicing his field goals for football. He kicks a football and it reaches a maximum height of 55 feet and lands 82 feet from where he kicked it. If the goal post is 10 feet above the ground and 76 feet away from where he kicks it, how many feet will it cross above the goal post (distance over the goal post when it crosses over it)? Round to 2 decimal places.

please explain how to solve this & provide the answer / show work

This situation can be modelled with a parabola

I suggest to make a coordinate system and draw the information and curve

[rain basin]

i tried that and still didn’t get how to get the answer

[woeful comet]

Can you show your work?

[rain basin]

i just don’t know how to do it, i just need someone to provide the work and the answer so i can understand

[woeful comet]

this is all i will provide

draw a coordinate system with the given information

throwing the ball would look something like that (parabolic)

you also know the general formula for quadratic equations

$y=ax^2+bx+c$
