Complete Question:
Alejandro jumped from a cliff into the ocean in Acapulco while vacationing with some friends.
Where t is the time in seconds and h is the height in feet
(a) How long did it take for Alejandro to reach his maximum height
(b) What was the highest point Alejandro reached
(c) Alejandro hits the water after how many seconds
Answer:
(a) 0.5 seconds
(b) 484 feet
(c) 6 seconds
Step-by-step explanation:
Given
Solving (a): Time to reach maximum height
This is the maximum of the function and it is calculated using:
Where
So:
Solving (b): Highest point reached
Time to reach the highest point is 0.5.
So, the highest point is: h(0.5)
Solving (c): Time he hits water.
At this point, h(t) = 0
So;
Factorize
Divide both sides by -16
Expand
Factorize
Time can't be negative.
So:
Look at the hundreds values. So look at 250. 250 rounded to the nearest hundred would be 300. So your final answer would be 8300.
