An object was dropped from a 360-foot tall building. The object falls 10 feet every second. The height of the object, y, is a function of the number of seconds, x, the object was in the air. What is the domain of the function for this situation? a 0 ≤ x ≤ 10
b 0 ≤ y ≤ 360
c 0 ≤ x ≤ 36
d 10 ≤ y ≤ 360

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.)

The weights of players in a basketball league are distributed normally. the distance (d) of each player's weight (w) from the mean of 86 kilograms was computed as follows: d = |w - 86| if d is greater than 7 for approximately 5% of the players, what is the approximate standard deviation of the players' weights? a. 1.75 kilograms b. 3.5 kilograms c. 4.3 kilograms d. 7 kilograms
