!!!!!!!!!!!!!!!!!!!!!!!!!PLEASE HELP!!!!!!!!!!!!!!!!!!!!
The height of a human cannon ball, "Cano", can be described by the formula h = 8 + 10t - t2 , where h is the height in metres above ground level and t is the time in seconds.
Cano is projected out of a cannon from the top of a building and lands on a soft mat. The mat is placed in a hole in the ground so that the top of the mat is level with the ground (hah! only in a math problem...)

a) What is the height of the cannon above the ground?
Round your answer to the nearest whole number.

b) How many seconds does it take Cano to reach the highest point on the path he is travelling? Round your answer to the nearest tenth.

c) What is the maximum height Cano reaches?
Round your answer to the nearest whole number.

d) To the nearest hundredth of a second, how long does it take Cano to land on the mat?
