A toy is thrown. Its height in feet (t) seconds is given by h(t) =112t - 16^2. Based on the equivalent forms of the function h(t) =112t - 16^2=t ⋅ (112-16t). What's the ball's height if thrown for 1 second? How many seconds does it take to hit the ground?

Prove that 16^4-2^13-4^5 is divisible by 11.
