3 -.BALLOON Treyvon is standing 9 yards from the base of a hill that has a slope of
He throws a water balloon from a height of 2 yards. Its path is modeled by
h(x) = -0.1x2 + 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?

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
