Answer:
After t = 4 the rocket will hit the ground.
Step-by-step explanation:
We are given a parametric equation as x = 3t² and y = - 4t + 16.
If we assume that the x is a measure of horizontal distance, y is the measure of vertical distance and t is the time of travel of the rocket, then by making y = 0, we will get the time to hit the ground.
Hence, - 4t + 16 = 0
⇒ t = 4
Therefore, after t = 4 the rocket will hit the ground. (Answer)
If the principal randomly selects a student in grade 12 so this means we focus on just the "grade 12" row. No other rows will be looked at here<span> what is the probability that the student is in favor of extending the school day?"</span> find the number in favor (who also happen to be in grade 12) then divide that number by the total number in grade 12 make sense.
so it would be .37
