At time t = 0, water begins pouring into an empty container at a constant rate. The water pours into the container until it is full. As the water begins to pour into the container at a constant rate, the depth of water in the container increases at an increasing rate for a period of time, and then the depth of water increases at a decreasing rate until the container is full. Which of the following containers would be appropriate for the given scenario?
Container A
Container B
Container C
Container D
Answer explanation
The container narrows then widens, increasing rate to decreasing rate.

For his birthday, Mr. Passwater decides to go skydiving. As Mr. Passwater begins falling toward the ground below, the distance he falls increases at an increasing rate until he pulls his parachute. Once his parachute opens, the distance he falls increases at a decreasing rate until he safely lands on the ground. Which of the following graphs could depict this situation, where time, in seconds, is the independent variable and the total distance he has fallen, in feet, is the dependent variable?
Answer explanation
The distance he falls increases at an increasing rate(concave up), then the distance he falls increases at a decreasing rate(concave down).

Once his parachute opens, the distance he falls increases at a decreasing rate until he safely lands on the ground. Which of the following graphs could depict this situation, where time, in seconds, is the independent variable and his distance from the ground, in feet, is the dependent variable?
Answer explanation
The distance to the ground is decreasing and becomes zero. He is approaching the ground at an increasing rate (more negative is concave down) then at a decreasing rate (less negative is concave up)

The figure shows a conical tank with water pouring into it. At t = 0, water begins to pour into the empty tank. The rate that water pours into the tank varies in such a way that the depth of the water inside the tank increases at a constant rate with respect to time. Which of the following graphs could depict this situation, where the depth of the water inside the tank, in feet, is the independent variable and the volume of water inside the tank, in cubic feet, is the dependent variable?
Answer explanation
The volume increases at a decreasing rate (concave down)
