Question

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

65
300<-16t^2+1000
It is D on Edgenuity for anyone who wants a simple answer

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