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 =

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with
