1. A swimming pool is twice as long as it is wide. It took 1,224 square feet of material to covar a 6-foot wide deck around the pool. How wide is the pool?
2. The height reached by a ball thrown vertically upward is directly proportional to the square of tis intial velocity. If a ball reaches a height of 46m when it is thrown upward with an inital velocity of 30meters/second, what height will the ball reach if the initial vertical velocity is 40 meters/second?
1. As the figure shown (you can find the figure in the attached word file), let's assume the wide of the pool is x feet, the long now is 2x. And the long and ...
The first part of the solution explains how to find the width of the swimming pool in detail. The second step-by-step solution elaborates on how to find the height of a ball thrown vertically upward.
