A ball is shot from a cannon into the air. The equation that's gives the height (h) of the ball of any time (t) is: h(t)= -16t^2 + 40t + 1.5

26.5 units

Step-by-step explanation:

The height of the ball at any time t is given by :

...(1)

We need to find the maximum height of the ball.

For maximum height, put

i.e.

Put t = 1.25 in equation (1) to find the maximum height.

So,

So, the maximum height reached by the ball is 26.5 units.

not sure but it may be b, as i said i'm not sure.
