A golf ball is hit so that when it is directly above a point that is x feet from the golfer, it is
h(x)= 30x-1/10x^2 feet above the ground
How far from the golfer will the ball hit the
ground?
**
when the ball hits the ground, h(x)=0
30x-1/10x^2=0
-0.1x^2+30x=0
-x^2+300x=0
-x(x-300)=0
-x=0 (reject)
x-300=0
x=300
How far from the golfer will the ball hit the
ground? 300 ft, ans (E)
