Avalve in a full 6000 gallon water tank is slowly opening. water flows out of the tank through the valve. the flow rate in gallons per hour is given by the function f(t)=300 t^2 where t is in minutes.
how much water flows out the tank in the first 7 minutes?
how many minutes does it take for the tank to be completely empty? ,

Find the zeros of each function. f(x) = 6x^2 - 7x - 20
