Question

A person sitting in the top row of the bleachers at a sporting event drops a pair of sunglasses from height of 24 feet. the function h= -16X squared + 24 represents the height h ( in feet) of the sunglasses after x seconds. how long does it takes the sunglasses to hit the ground.) please someone help me I will mark Brainliest​

Answer 1

Answer: square root of 3/2 seconds

Step-by-step explanation:

h=-16x²+24

Set the height to be 0

0=-16x²+24

-24=-16x²

24=16x²

24/16=x²

x²=3/2

x= square root of 3/2

Answer 2

you have to set the equation equal to 0 to represent when it hits the ground

0=-16x²+24

-24=-16x²

-24/16=x² --> -3/2=x²

x=-1.22474
