Question

A. A tourist accidentally drops her lip balm off the Golden

Gate Bridge. The bridge is 220 feet from the water of the
bay. The height of the lip balm is given by the polynomial
-16t² + 220, where t is time in seconds. How far above
the water will the lip balm be after 3 seconds?

Answer 1

To find how far above the water the lip balm will be after 3 seconds, we need to evaluate the polynomial -16t² + 220 when t = 3.

Substituting t = 3 into the polynomial, we get:

-16(3²) + 220 = -16(9) + 220 = -144 + 220 = 76

Therefore, after 3 seconds, the height of the lip balm above the water will be 76 feet.
