Answer:
A
B
Vertex=(6,576)
Step-by-step explanation:
The problem gives us the following data:
A.
Thus the function is
The graph of h has the shape of an inverted parabola. Recall if the coefficient of the quadratic term is negative, the parabola is concave down, so it has a maximum value.
Part B
Let's take the function of h
Factoring by -16
Completing squares
Factoring
Rearranging
We can get the coordinates of the vertex from this standard form of the parabola.
Vertex=(6,576)
The maximum value means that at t=6 seconds, the firework will be 576 feet high and then it will start falling back to the ground.
