Answer:
14.52 seconds.
Step-by-step explanation:
We have been given that the height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation . We are asked to find the time, when the rocket will hit the ground.
We know that the rocket will hit the ground, when height will be 0. So to find the time when rocket will hit the ground, we will substitute in our given equation as:
Let us solve for x using quadratic formula.
Upon rounding to nearest 100th of second, we will get:
Since time cannot be negative, therefore, the rocket will hit the ground after 14.52 seconds.
26/44 - 18/44 = 8/44
26 - 18 = 8
even though it is subtraction, you do not subtract the bottom numbers (denominator).
so your answer is 8/44
if you simplify it, you will get 4/22 and then 2/11
your simplified answer is 2/11 (is this on there?)
