A tank has 45 gallons of water in it at time t = 0 minutes. Water begins to be pumped into the tank at timet = 0. A different pipe is draining water from the tank starting at t = 0. Water is being removed from the tank at a rate modeled by the function V(t) = –9(1.05)' + 23, where V (t) is measured in gallons per minute. Water is being pumped into a tank at a rate modeled by the function F(t) = -8(0.85) + 14, where F(t) is measured in gallons per minute. What is the minimum amount of water in the tank from t = 0 to t = 12? You may use a calculator and round to the nearest thousandth. Use proper units and show how you got your answer.

Question
round to the nearest thousandths
A tank has 45 gallons of water in it at time
t = 0 minutes. Water begins to be
pumped into the tank at timet = 0. A
different pipe is draining water from the
tank starting at t = 0.
Water is being removed from the tank at a
rate modeled by the function
V (t) = -9(1.05)' + 23, where V (t) is
measured in gallons per minute.
Water is being pumped into a tank at a
rate modeled by the function
F(t) = -8(0.85)* + 14, where F(t) is
measured in gallons per minute.
What is the minimum amount of water in
the tank fromt
0 to t
12? You may
use a calculator and round to the nearest
thousandth. Use proper units and show
how you got your answer.
