The height, in feet, after x seconds of an object launched straight up can be found by the function h(t) = ‐16t² + v0t + h0 , where v0 is the initial velocity of the object and h0 is the initial height. If a ball is thrown straight up into the air from a height of 6ft and an initial velocity of 29 ft/s, after how many seconds will the ball hit the ground?

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.a city water tank holds 20 gallons of water. a technician empties 25% of the tank. how many more gallons of water must be removed from thetank so that it has 5 of the water that it started with: the technician must removemore gallons of water for the tank to have 5 of the water that it started with.
