Answer:
The ballon will hit the ground after 1 s.
Step-by-step explanation:
In this case we want to solve for x, but were given a equation to the height of the ballon, we can organize it in a way that isolates x on the left side of the equation so it can be used to what we want. So we have:
h = -16x^2 +16
h + 16x^2 = 16
16x^2 = 16 - h
x^2 = (16 - h)/16
x = sqrt(16 - h)/sqrt(16) = sqrt(16 - h)/4
When the ballon hits the ground it's height is 0 feet, so we substitute that on our equation and we'll have the right answer.
x = sqrt(16 - 0)/4 = sqrt(16)/4 = 4/4 = 1 s
