Question

5. You throw a water balloon into the air and its path is modeled by

h =-d² + 4d + 5 where h is the height in feet and d is the horizontal
distance in feet.
a. When the horizontal distance is 1 (d=1), what is the height of
the balloon?
b. Your arch nemesis (enemy) is standing about 33 feet away from
you, does the water balloon hit them? (Explain your answer)

Answer 1

Explanation:

Your POST does not match the picture....I will use the equation in the picture

h = - 1/8 d^2 + 4d + 5

a) when d = 1 find 'h' by putting '1' in the equation for 'd'

h = -1/8 *(1^2) + 4(1) + 5 = 8 8/9 ft high

b) when d = 33

h = -1/8 ( 33^2) + 4 (33) + 5 = .875 ft = 7/8 ft high

yah...it will probably hit your enemy
