Aball is shot up in the air and its height, h, above the ground in feet is given by the function h(x)= -16x^2 + 44x, where x is the number of seconds the ball has been in flight. find the maximum height that the ball attains. round your answer to the hundredths place.

So the maximum height is another word for vertex's y-coordinate. The easiest method to find the vertex is to find the axis of symmetry for the x-coordinate and then plug the axis of symmetry into the equation to solve for y.

Firstly, the equation for the axis of symmetry is , with b = x coefficient and a = x^2 coefficient. Using our equation, we can solve for the axis of symmetry as such:

Now that we have the x-coordinate, plug it into x and solve for y:

In short, the maximum height is 90.75.

can i get the link to the assignment?

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
