The equation below expresses the approximate height h, in meters, of a ball t seconds after it is
launched vertically upward from the ground.
h(t) = –16t2 + 25t. At how many different times will the ball be 7 ft. High?

The ball will be the 7 ft high at 2 different times.

Step-by-step explanation:

The height in meters of the ball is given by the following equation:

7 feet high

The height, by the equation, is given in meters, so we have to work in meters. Since each feet has 0,3048 meters, 7 feet have have 2.1336 meters. So, we have to solve the following equation

At how many different times will the ball be 7 ft. High?

We have to find the number of solutions for the equation above.

It is given according to the value of . If it is positive, there are two solutions, zero one solution and negative no solutions.

In this equation . So

Since the coefficient is positive, the ball will be the 7 ft high at 2 different times.
