Y= -6x2 + 363 She defined the variables for us:
y= the height of the tennis ball in feet
x = seconds after the ball is hit with the
How long does it take for the ball to hit the ground in
seconds?
Hint: When the ball hits the ground, the height of the tennis
ball, y, is 0.

At a sand and gravel plant, sand is falling off a conveyor and onto a conical pile at a rate of 16 cubic feet per minute. the diameter of the base of the cone is approximately three times the altitude. at what rate is the height of the pile changing when the pile is 12 feet high? (hint: the formula for the volume of a cone is v = 1 3 πr2h.)

What is the greater volume 72 quarts or 23 gallons
