5) Suppose that a very contagious virus is introduced to a population. Scientists work quickly to find a vaccine to limit the number of people who will be infected. Studies show that P percent of the population will be infected t weeks after the virus is first detected according to the equation: 30 P(t) = 1+25e-0.2t a. Sketch the graph of this function. b. Estimate the time (in weeks) when the virus seems to spreading at the fast rate. c. When the virus is first detected at time t = 0, what percent of the population has the virus according to this model?
