- 1. Given the following SIR diagram, where h are some costly self-protective activities that people can take to avoid contracting the disease. h(p, I) = nl - apl + C. C is a constant, p is the price of costly self-protective activities. Birth (BI, – h(p, l))S. Susceptible Infected Ads St Death ds (a) Write down dt (b) Solve for the steady state infected population I*. (c) Calculate the prevalence elasticity of self-protection.Using the systematics of exponential processes, the time scale for getting out of a pandemic at its peak through exponential decay of the infection rate or the death rate is estimated from: If the delta variant death rate per day (Po) peaked at 2000 in late September and declined at the national rate of − 1% per day, what is t, the time in days to defeat the virus (i.e. time until the last person dies)? answer choices: 350 525 450 760Question 1.

[Ans. 297 s]After the first covid-19 case found in Olde town, a group of volunteers started counting the number of case and kept the record of number of infected people in daily basis. After collecting data for 18 days they made a graph as shown in the figure. It was perfect exponential trendline fit. The fit equation is shown in the plot. The equation has 0.2 multiplying the days.
