1. When a cannonball is fired, the equation of its pathway can be modeled by h = -1612 + 128t.
a) Find the maximum height of the cannonball.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

i think the answer is 90 hope this
