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 (when t = 0) and 30876 new cases 79 days later. Find an exponential model for the number of new cases at any time t, in days after January 26, 2020. (Note: if you use decimal approximations for the numerical constants in your work, be sure to retain enough significant figures through your work to ensure that subsequent answers are correct.) a. P(t)= 684(1.05)* b. According to your model, the predicted number of new cases after 27 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 69365? Number of days
