Step-by-step explanation:
The height, h in feet, of a rocket is given by, where t is time in seconds.
...(1)
We need to find the maximum height of the rocket and find the time the rocket was in the air. For maximum height, put
So, it will reach its maximum height in 2 seconds.
Now put t = 2 in equation (1) as follows :
So, the maximum height of the rocket and find the time the rocket was in the air is 254 feet and 2 seconds respectively.
Answer:
They have to go 30 m below sea level to reach wreckage.
Step-by-step explanation:
jane and her friends are diving to explore a wreckage from a ship that is 40 meters below sea level the platform they dive from is 10 meters above sea level.
Below sea level means = -40 m
Above sea level means = +10 m
It means,
-40 m + 10 m
= -30 m
Hence, they have to go 30 m below sea level to reach wreckage.
The answer is The second choice (B)
If x is the time, in hours, then:
x(55)=x(50)+15
5x=15
x=3 hours before Aisha is ahead of Luke
hope this helps you!
