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)
Answer:
the length of the shortest ladder is 11.41 feet
Step-by-step explanation:
The computation of the length of the shortest ladder is shown below:
AB^2 = AC^2 + BC^2
AB^2= (10)^2 + (5.5)^2
AB^2= 100 + 30.25
AB^2 = 130.25
AB = 11.41 feet
hence, the length of the shortest ladder is 11.41 feet
