Question

seconds can be modeled by the expression −16t^2+32t+7
. What does 7 represent in the context of the problem?(1 point)
Responses

7 does not make sense as a value in this problem.

7 represents the number of rocks Kenny found at the pond.

7 represents the height of the rock when Kenny throws it.

7 represents the number of seconds Kenny hold the rock before throwing it.

Answer 1

In the context of the problem, the expression for the height of the rock is given by \( -16t^2 + 32t + 7 \). The term \( 7 \) represents the height of the rock when Kenny throws it. Therefore, the correct response is:

7 represents the height of the rock when Kenny throws it.
