An object is dropped from a small plane. As the object falls, its distance, d, above the ground after t seconds, is given by the formula d = –16t2 + 1,000. Which inequality can be used to find the interval of time taken by the object to reach the height greater than 300 feet above the ground?

Step-by-step explanation:

We are given the following in the question:

where d is the distance of an object above the ground and t is in seconds.

We have to find the time interval such that distance is greater than 300 feet above the ground.

is the required time interval.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
