Hey i have a question for Maths B in queensland, australia. Here it is...
Water flows in and out of a tidal pool according to the equation:
g = 50SIN((2π/6)x)
Where g is the flow of water in cubic meters per hour and x is the time in hours. At g=0, the water flow is 0. Greenies who are protesting about water quality begin measuring the flow into and out of the pond 3 hours after g=0. Over a certain period of time approximately 119 cubic metres of water was measured. For how long was the flow measured?
Any help here would be appreciated
