The height, h, in feet, of an object dropped from the top of the Empire State Building can be estimated using the equation h= -16t^2+1,454, where t is the time

Question

I couldn't fit my whole question so here it is: The height, h, in feet, of an object dropped from the top of the Empire State Building can be estimated using the equation h= -16t^2 + 1,454, where t is the time in seconds after the object is dropped. What is the best estimate for how far above the ground will the object be after 8 seconds? 

 

 

The choices are: 1,390 feet

                               1,326 feet

                               512 feet

                                430 feet

Answer 1

Plugging in t=8,

1454 - 16*8^2 = 1454 - 16*64 = 430
