Solve the problem.Let T be the amount of time (in seconds) it takes a baseball to fall to the ground when the ball is dropped from h feet above the ground. A good model is Simplify the right-hand side of the equation and determine how long it would take for a baseball to reach the ground if it were dropped from the top of a building that is 930 feet tall. Round to the nearest tenth when necessary.
