a hole is punched in the side of a cylindrical water tank and water begins to flow out. The hole is punched at time t=0 min. The volume of water in the tank, V litres, at any time t when the water is flowing out is given by V=t^2 - 16t + 100 .
a. how much water is in the tank at the beginning? i got 100 litres bt from my calculations from the next question I think it may b wrong.
b. How long does it take to empty the tank?is this just completing the square?
c. How much water flows out of the tank and how much is left inside?
d. Determine a formula for the time t when the tank has a given volume V. State the domain and range of this function.
