Question

5. (12 pts) The 7-day moving average of COVID-19 cases from mid July, 2021 to mid November, 2021 can be modeled by $N(t) = 21te^{-0.5t}$ $(0 \le t \le 4)$ where t is measured in months. N is the 7-day moving average of COVID-19 cases and t = 0 corresponds to July 15, 2021. (a) Find N'(t) by demonstrating the product rule. Do not simplify. (b) When does the 7-day moving average number of COVID-19 cases reach a maxi- mum? Show how to find this value algebraically using N'(t).

Step 1

5t). The product rule states that if we have two functions u(t) and v(t), then the derivative of their product is given by: (d/dt)(u(t)*v(t)) = u'(t)*v(t) + u(t)*v'(t) In this case, u(t) = 21t and v(t) = e^(-0.5t). Show more…

The 7-day moving average of COVID-19 cases from mid-July 2021 to mid-November 2021 can be modeled by N(t) = 21t*e^(-0.5t) (47150), where t is measured in months. N is the 7-day moving average of COVID-19 cases, and t=0 corresponds to July 15, 2021. Find N(t) by demonstrating the product rule. Do not simplify. Show how to find this value algebraically using N(t).
