HIYA !! please help as soon as possible :)) This activity will help you meet these educational goals:
You will create and use a quadratic expression to model the projectile motion of a ball of paper and then manipulate the expression to determine specific contextual information.

Jacob’s classroom is on the second floor of his high school building. He’s sitting at his desk and trying to solve a quadratic equation. Every time he makes a mistake, he crumples a piece of paper and attempts to throw it in the trash can. One time, however, he accidentally throws the ball of paper out the window. The quadratic expression -16t2 − 8t + 24, where t is the time (in seconds), models the height (in feet) of the crumpled ball of paper after passing through the open window at t = 0.

Part A
In the expression -16t2 − 8t + 24, what does the constant term represent?

Part B
Write the quadratic expression -16t2 − 8t + 24 in factored form.

Part C
Determine the zeros of the expression -16t2 – 8t + 24.

Part D
What do the zeros represent in the context of the situation for reasonable answers?
