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?

Answer 1

when is height 300?
300<-16t^2+1000
-700<-16t^2
t<sqrt (700/16)

Answer 2

Answer 3

65

Answer 4

300<-16t^2+1000

Answer 5

It is D on Edgenuity for anyone who wants a simple answer

-16^2 +1000 > 300 for a long answer!
