Given data:

The expression for the height of the object is h= -16t^2 +144.

When the object hits the ground its height becomes zero.

\begin{gathered} h=0 \\ -16t^2+144=0 \\ -16t^2=-144 \\ t^2=9 \\ t=3,\text{ -3} \\ t=3\text{ s} \end{gathered}

Consider only positive value of time.

Thus, after 3 second object hit the ground.

Ella already knew 5 appetizer recipes before starting culinary school, and she will learn 2 new
Natalija [7]

A = 2w+5

example: on week three, she would have the recipes from the other weeks that you have to account for as well as the extra five

2(3)+5=11 so A would equal 11 by week three.

Use multiplication because it is essentially repeated addition.

2(from week 1) + 2(from week 2) + 2(from week 3) + 5(prior to school) =11
