The Millau Viaduct, at 1125 ft, is the highest bridge in the world and overlooks the river Tarn in France. An object is dropped from the top of the bridge. Neglecting air resistance, the height of the object at time t seconds is given by the polynomial function P(t) = -16t2+ 1125. Find the height of the object when t = 6 seconds.

o 933 ft.

o 1177 ft.

o 549 ft.

o 1317 ft.
