Question 196644: I keep getting the incorrect answer to the following problem, I'm not sure where my error was, can you help me?
A large pond is stocked with fish. The fish population P is modeled by the formula P = 4t + 8√t + 110, where t is the number of days since the fish were first introduced into the pond. How many days will it take for the fish population to reach 500?
thanks! Answer by edjones(7569) (Show Source):
You can put this solution on YOUR website! 4t+8sqrt(t)+110=500
t=79.65 days Answer. Quadratic equation. [t=119.35 is extraneous]
