At the beginning of the COVID-19 pandemic, the number of new cases was growing exponentially. There were 684 new cases on January 26, 2020 (whent = 0) and 14356 new cases 72 days later. Find an exponential model for the number of new cases at any time t, in after January 26, 2020. (Note: if you use decimal approximations for the numerical constants your work, be sure to retain enough significant figures through your work to ensure that subsequent answers are correct.) a. P(t)= b. According to your model, the predicted number of new cases after 39 days = C. How many days is the doubling time? Doubling time = days. d. How many days after January 26, 2020 (when t = 0) does your model predict the number of new COVID-19 cases to reach 82884? Number of days = e. To what date does this correspond?
