If an object is dropped from a height of 198 feet, the function h(t)=-16t squared +198 gives the height of the object after t seconds. When will the object hit the ground?

The object hits the ground after 3.52 seconds.

Step-by-step explanation:

The height of the object after t seconds is given by the following function:

When will the object hit the ground?

It hits the ground when . So

Since time is a positive measure, we only take the positive value

The object hits the ground after 3.52 seconds.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

the 4th choice is the correct one
