NASA launches a rocket at t=0 seconds. Its height, in meters above sea-level, in terms of time is given by h=−4.9t2+244t+269.

how high is the rocket after 9 seconds

how high was the rocket when it initially launched

The height of the rocket after 9 seconds is 2068.1 meters.

The height of the rocket when it initially launched is 269 meters.

Step-by-step explanation:

Given, NASA launches a rocket at seconds.

Its height, in meters above sea-level, in terms of time is given by

To find, the height of the rocket after 9 seconds put t=9, we get

Hence, the height of the rocket after 9 seconds is 2068.1 meters.

To find, the height of the rocket when it initially launched put t=0, we get

Hence, the height of the rocket when it initially launched is 269 meters.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
