A water drip system in a garden uses 2/3 cups of water every 1/6 of an hour. a) How much water is used in 1 hour?

b) Use your equation to calculate how much water is used after 24 hours?

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 =
