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)
The first year it decreased by 20%. Multiply the cost of the car by 80% ( 100%-20% = 80%)
24,000 x 0.8 = 19200
After the first year the car was valued at €19,200
Now divide the value after the 2nd year by the value after the first year:
16128 / 1900 = 0.84 * 100 = 84%
The car is 84% of the value.
100 - 84 = 16
The cars value decreased by 16% during the second year.
