A biologist is modeling an infestation of fire ants. He determines that the area affected by the ants is given by A(n)=k*(1.5)n+c hectares, where n is the number of weeks after the initial observation and k and c are constants. The model is graphed alongside with point (3, 580). a. Using technology, what is the value of k and c? b. Estimate the time taken for the infested area to reach 1000 hectares.
