Shown below is the graph of the flow rate f(t) of a pipe, in gallons per minute. Here, t = the number of minutes. Using this information, find + (F(1) f(t) dt, which gives the total number of gallons of water that flowed through this pipe in 7 minutes. Velocity (Gallons/Minute) > 5 4 2 + O -1 - 2 3 4 Time (In Minutes) 6.0 7 X ff(1) dt = f(t) dt = 25 gallons 0 7 of f(1) dt = 26 gallons Off(t) dt = 23 gallons 7 | f(t) dt = 24 gallons of f(1)
