Answer:

a) V(t) = 24 - 2t

b) As t increases from 3 to 6, v varies from 18 gallons to 12 gallons.

Step-by-step explanation:

The volume of the tank in terms of the time can be described by the following equation:

V(t) = V(0) - at

In which V(0) is the initial volume and a is the hourly decrease rate.

a. Write a formula that expresses v in terms of t.

The tank initially contains 24 gallons of water, which means that V(0) = 24

Drains at a constant rate of 2 gallons per hour, so a = 2

Then

V(t) = V(0) - at

V(t) = 24 - 2t

b. As t increases from 3 to 6, v varies from _________ to _________

V(t) = 24 - 2t

V(3) = 24 - 2*3 = 18

V(6) = 24 - 2*6 = 12

So as t increases from 3 to 6, v varies from 18 gallons to 12 gallons.
