Question 2 of 4
Alexxandr [17]

Answer:

The time it took for the bottle rocket to reach a height of 200 feet is 60 seconds.

Step-by-step explanation:

The function for the height of the bottle rocket (in feet), <em>t</em> seconds after  it is launched is:

h(t)=1157-16\ t

Compute the value of <em>t</em> as follows:

h(t)=1157-16\ t

200=1157-16t

 16t=1157-200\\16t=957\\

     t=59.8125\\t\approx60

Thus, the time it took for the bottle rocket to reach a height of 200 feet is 60 seconds.
