Question

Kenny is standing on top of a boulder at his neighborhood pond. He picks up a small rock, so that it is 7 feet off the ground, and throws the rock into the pond. The height of the rock after t seconds can be modeled by the expression -16t to the power of 2 + 32t + 7. What does 7 represent in the context of the problem?

Answer 1

In the context of the problem, the number 7 represents the initial height of the rock when Kenny throws it into the pond. Specifically, it indicates that the rock is initially 7 feet off the ground at the moment it is released. This height is the starting point from which the rock begins its trajectory as it is thrown.
