Tim throws a stick straight up in the air from the ground. the function h = –16t2 + 48t models the height, h, in feet, of the stick above the ground after t seconds. which inequality can be used to find the interval of time in which the stick reaches a height of more than 8 feet?
a.) –16t2 + 48t > 8
b.) –16t2 + 48t < 8
c.) –16t2 + 48t ³ 8
d.) –16t2 + 48t £ 8

The correct option is A.

Step-by-step explanation:

The function for height of the stick above the ground after time t is given as

Where, h is height of the stick above the ground in feet and t is time in seconds.

We have to find the interval of time in which the stick reaches a height of more than 8 feet. It means

Using the given function, we get

Therefore option A is correct.
