A ball is thrown from an initial height of 5 feet with an initial upward velocity of 33 ft/s. The ball's height $h$ (in feet) after $t$ seconds is given by the following. $h = 5 + 33t - 16t^2$ Find all values of $t$ for which the ball's height is 21 feet. Round your answer(s) to the nearest hundredth. (If there is more than one answer, use the "or" button.)

Step 1
The equation is h = 5 + 33t - 16t^2, where h is the height in feet and t is the time in seconds. We are asked to find the time(s) t when the height of the ball is 21 feet. Show more…

A ball is thrown from an initial height of 7 feet with an initial upward velocity of 21 ft/s. The ball's height h (in feet) after t seconds is given by the following equation: h = 7 + 21t - 16t^2. Find all values of t for which the ball's height is 13 feet. Round your answer(s) to the nearest hundredth. (If there is more than one answer, use the "or" button.)

A ball is thrown from an initial height of 5 feet with an initial upward velocity of 28 ft/s. The ball's height h (in feet) after t seconds is given by the following equation: h = 5 + 28t - 16t^2 Find all values of t for which the ball's height is 13 feet. Round your answer(s) to the nearest hundredth. (If there is more than one answer, use the "or" button.)
