h(t)=144t-16t^(2) The function above represents the height, in feet, a ball reaches t seconds after it is tossed in the air from groud level. a. What is the maximum height of the ball? b. After how many seconds will the ball hit the ground before rebounding?

h(t) = − 16t^2 + 110t + 72 The function above models the height h, in feet, of an object above ground t seconds after being launched straight up in the air. What does the number 72 represent in the function?

h=-4.9t^(2)+25t The equation above expresses the approximate height h, in meters, of a ball t seconds after it is launched vertically upward from the ground with an initial velocity of 25 meters per second. After approximately how many seconds will the ball hit the ground?

Questions 37 and 38 refer to the following information. h(t)=-4.9t^(2)+88.2t When a projectile is launched from ground level, the equation above gives the number of meters in its height, h, after t seconds have elapsed. Q. What is the maximum height the projectile reaches, correct to the nearest meter?
