Treyvon is standing 9 yards from the base of a hill that has a slope of 3/4. He throws a water balloon from a height of 2 yards. Its path is modeled by h(x)=−0. 1x^2+0. 8x+2, where h is the height of the balloon in yards and x is the distance the balloon travels in yards.




a. Write a polynomial equation to represent the situation.



b. How far from Treyvon will the balloon hit the hill? If necessary, round to the nearest tenth
