A "logistic model" is a form of exponential growth that has an upper limit. It is often used for modeling disease outbreaks.The number of cases in a virus outbreak is 5000 given by the logistic model V where t is measured in days. -ht 1 1+39e a) How many people have the virus on Day Zero? b) If 2500 people are sick on Day 12, show that h = In(39). %3D 12 c) A researcher incorrectly assumes that an exponential model is more appropriate for the outbreak; he calculates a model of V 90 (3) ". Find the two values of t (correct to 3 decimal places) for which the 2 models predict the same number of sick %3D people. Justify your answer with a sketch.
