Ответ:
12 seconds
Step-by-step explanation:
The given function is
where h represents the height of the flare in feet above the sea t sec after it is launched.
We need to find the time taken by flare to return to the sea. At sec level the height of flare is 0.
Substitute h=0 in the given function.
Using zero product property we get
It means at t=0 and t=12 the flare is at sea level.
The time taken by flare to return to the sea is
Therefore, the time taken by flare to return to the sea is 12 seconds.
