Maria is draining her hot tub at a rate of 5.5 gallons per minute. Is the amount of water left in the pool a function of the amount of time she has been draining it?



Sagot :

The amount of water in the pool after t minutes is modeled by the linear function [tex]V(t) = V(0) - 5t[/tex], hence it is a function of time.

A linear function for the amount of water in the pool, considering that it is drained at a rate of a gallons per minute, is modeled by:

[tex]V(t) = V(0) - at[/tex]

  • In which V(0) is the initial volume.

In this problem, draining her hot tub at a rate of 5.5 gallons per minute, hence [tex]a = 5.5[/tex], and:

[tex]V(t) = V(0) = 5.5t[/tex]

Which is a function of time.
