10. The Spanish u was a worldwide epidemic that began in 1913 and lasted approximately 2 years. During the rst few months of the epidemic= the u spread rapidly through a Canadian city as shown in the table below. Time (months) Number of Conrmed Cases 150 823 24 84 67'0\"! 14034 a. Determine the equation of the exponential regression ancom in the form C = (15' , that models the number of conrmed cases, C, as a function of time, 1'. Express the values of a and t: to the nearest hundredth. (2 marks) h. Use the exponential regression equation to determine the time that it will take= to the nearest tenth of a month= for the number of eonfn'med cases to equal 20 000. Show or explain how you found the answer for full marks. (2 marks) c. Determine the equation of the logarithmic regression function r = a + 5?th , that models time, I, as a function of conrmed cases, C. Express the values of a and b to the nearest hundredth. (2 marks) d. Use the logarithmic regression equation to determine the time it will take= to the nearest tenth of a month for the number of confirmed cases to equal 20 000.
