a bastetball is passed through the air. The height h of the ball in feet after the distance d in feet the ball travels horizontally is given by h=-d^2+ 10d+ 5. How far horizontally from the player passing the ball will the ball land on the ground?
You want the (positive) distance when the height is 0, 0= -d^2 + 10d +5.
You would factor that out(You'd get radicals), and the final answer would be
5±30−−√
You'd take the only positive one of the two, 5 + srt(30)
I hope I did that right :/
