п»їDirections: Answer each one of the following concerns algebraically. You could sketch the graph of the parabola to assist you visualize the flight in the ball.

1 ) A normal water balloon is usually tossed in the air with an upwards velocity of 25ft/s. Its height h(t) in ft after t seconds is given by the function h(t) sama dengan -16t2 & 25t & 3.

a) After how many mere seconds will the balloon hit the floor?

b) What will the height always be at big t = one particular second?

installment payments on your A soccer is that passes the air and caught by ground level to get a touchdown. The peak h in the ball in feet is given by h = -d2 + 12d + six, where g is the length in toes the ball travels flat. How far from your player moving the ball will the ball be caught?

3. A basketball is passed through mid-air. The height h of the ball in foot after the distance d in feet the ball travels horizontally has by l = -d2 + 10d + your five. How far flat from the participant passing the ball will the ball arrive at the ground?

5. A ball is motivated in the air toward the hole by an elevated tee with an upward speed of one hundred sixty ft/s. The height they would in foot after t seconds is definitely gen by function h = -16t2 + 160t + 18. How long can it take pertaining to the golf ball to reach the maximum level? What is the golf ball's maximum elevation?

5. A baseball player hit a ball with an way up velocity of 46 ft/s. Its height h in feet after t secs is given by the function l = -16t2 + 46t + six. What is the most height the ball extends to? How long will it take the hockey to reach the ideal height? How much time does it take intended for the ball to hit the earth?

6. A golf ball can be chipped in the air from being a mere hill with an up velocity of fifty ft/s. It is height l in toes after to seconds is given by the function h = -16t2 & 50t + 10. Precisely what is the maximum level? How long does it take for the ball to hit the ground?

six. A punter kicked the...
