Answer:

Step-by-step explanation:
The area of a triangle is given by
.
Substituting given values, we have:

Answer:
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.
