We can say that side lengths 6, 8 and 10 will make a right triangle. To make this statement, we use and the Pythagorean Theorem and show that they do, indeed work.

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
