h=-16t%5E2+%2B1100 Start with the given equation


h=-16%284.1%29%5E2+%2B1100 Plug in t=4.1


h=-16%2A16.81%2B1100 Square 4.1 to get 16.81



-268.96%2B1100 Multiply -16 and 16.81 to get 268.96 (ie -16%2A16.81=268.96)


831.04 Add -268.96 and 1100 to get 831.04 (ie -268.96%2B1100=831.04)


So at 4.1 seconds, the height of the object is 831.04 ft


So the answer is B)
