Question 1162092: To make boxes, a manufacturer cuts equal-sized squares from each corner of a 11-inch × 14-inch piece of cardboard, and then folds up the sides. The polynomial function
f(x) = 4x3 − 50x2 + 154x
gives the volume (in cubic inches) of the resulting box when a square with sides x inches long is cut from each corner. Find the volume of a box if 3-inch squares are cut out.

Question 1162345: An object has been thrown straight up into the air. The formula
h = vt − 16t2
gives the height h of the object above the ground after t seconds, when it is thrown upward with an initial velocity v.
Before a football game, a coin toss is used to determine which team will kick off. The height h (in feet) of a coin above the ground t seconds after being flipped up into the air is given by h = −16t2 + 70t + 9
How long will the coin be in the air?
