The height of a ball that was batted into the air at 160 feet per second is a function of t, the time in seconds after the ball was hit. The height is determined by subtracting 16 times the square of t from 160 times t. Which equation can be used to find t when the ball is 400 feet high?
A. 160t16t^2=400
B. (16016)t^2=400
C. 160(t^2t)=400
D. 160(16t^2)=400
E. 16t^2160t=400

h = height
t = time
h = 160 t  16 t ^ 2
400 = 160 t  16 t ^ 23
160 t  16 t ^ 23 = 400

Sorry my tipfeler.
Answer is A
h = 160 t  16 t ^ 2
400 = 160 t  16 t ^ 2
160 t  16 t ^ 2 = 400
