- The following model was estimated for COVID-19 in British Columbia before lockdown was in place:
lnY=2.66+.20*t
Where Y is total Covid-19 cases and t is time in days since the first occurrence. In how many days will cases double if this pattern persists? (Hint: Use the 70 rule after knowing what the daily the growth rate is…..)

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
