Okay Ms. Sue. I am in 8th grade but I am taking Algebra with 9th graders. I am very confused with my previous problem. I have asked my Dad but we are both getting confused. Now I have come up with 22. Is this my correct answer?
If a ball is thrown vertically upward from the ground, with an initial velocity of 64 ft/s, it's height h after t seconds is given by h=-16t^2+64t how long does it take the ball to return to the ground?
Jim shoots an arrow into the air. The height of the arrow in feet, t seconds after shooting, is shown by the function below. h(t)=64t-16t^2 What is the domain of the function and what does it represent?
