The function h(t)=-16t2+32t+128 represents the height of a cnnoj ball in feet t seconds after it is shot from a cannon. how many seconds does it take the cannonball to hot its target on thr grownd

4 seconds

Step-by-step explanation:

To solve this problem you will use the quadratic formula: .

Identify the a, b, and c values of the given quadratic equation:

Substitute these values into the quadratic formula.

Now split this into two equations.

Positive case:

Negative case:

Since time cannot be negative, the cannonball takes 4 seconds to hit its target on the ground.

a

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
