Question

The height of the object at 1 second is what amount of feet?

Answer 1

If t= 1s. Then let's replace t-value in the equation:

$\begin{gathered} \text{ -16t}^2\text{ + 1130= } \\ \text{ -16 \lparen1\rparen + 1130= } \\ \text{ -16 + 1130= } \\ 1,114\text{ feet. } \end{gathered}$

The height of the object at 1 second is 1,114 feet.
