When a cannonball is fired, the equation of its pathway can be modeled by h=-16t2 +128t. Find the maximum night of the cannon ball

256

Step-by-step explanation:

When the equation is graphed the highest point is (4,256). So 256 is the maximum height of the cannon ball.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
