Summer is approaching, so workers at the Lawrenceville Community Center are filling the pool. The volume of water in the pool x minutes after they start to fill it is given by the function f(x). The volume is measured in cubic feet. What does f(5) < f(10) tell you?

  The pool is being filled

Step-by-step explanation:

The function definition tells you ...

  f(5) = the volume of water in the pool 5 minutes after they start

  f(10) = the volume of water in the pool 10 minutes after they start

So, the inequality ...

  f(5) < f(10)

means the volume of water in the pool 10 minutes after they start is greater than it is 5 minutes after they start. In short, they are filling the pool.

  pythagorean theorem can be extended into three dimensions by creating a right triangle with two of its vertices lying in a horizontal plane. the result is the three-dimensional distance formula for 2 points.        x2 -x12 +y2 -y12+z2 -z1 2
