How high will the firework be when it explodes? (Look at Photo)

606 feet

Step-by-step explanation:

The fireword has a 5-second fuse, meaning that's how long it will take to explode.

Given the polynomial -16t² + 200t + 6, where t is the time in seconds

We need to subsitute 5 sec. (as stated in the question) for t in the polynomial, to find how high the fireworks will be when it explodes :

-16t² + 200t + 6 <== substitute 5 for t

-16(5)² + 200(5) + 6 <== square the exponent first

-16(25) + 1000 + 6 <== multiply

-400 + 1000 + 6 <== add

-400 + 1006 <== add

606 feet <== final answer

This means that it will be 606 feet high before it explodes.

Hope this helps!
