Question

A cannonball is shot straight up into the air. The height of the cannonball at time t is represented by the function f(t)=−16t^2+40t+5 .

What does the 5 represent?


the maximum height of the cannonball

the initial height of the cannonball

the time when the cannonball hits the ground

the initial velocity of the cannonball

Answer 1

the initial height of the cannon ball

Explanation:

Answer 2

the initial height of the cannon ball

Explanation:

- Time (t) is basically how many seconds or minutes you factor into the given function. 16(time in exact seconds or minutes)^2+40(time in exact seconds or minutes) +5

- The +5 can only be where the cannonball was initially fired from logically. The Velocity formula is already there for you to plug the time into^^^

(I used time in minutes/seconds to try and explain what the function is asking)
