(chatquestion)...For items 13 to 17: Let t represent the incubation period (in days) of QUAVID -a certain deadly virus that spreads quadratically with time. 13. The fraction of infected citizens of a population at any value of time t20 is best described by : Copyright © 2016 Pearson Education, Ltd. A) n(t) =e D) n(1) = B) n(1) =e E) n(t) = log, C) n(t) = 14. The quadratic curve in the previous item may be flattened by strict implementation of social/physical distancing between all members of the community. The fraction of infected citizens of a population at any positive value of time t is now described by: A) n(t)=e D) n(1) = B) n(1) = E) n(t) = log, C) n(t) =| 15. If the incubation period of QUAVID is 14 days, when does the flattened QUAVID curve peak? (Hint: Set the derivative to zero.) A) 28 days B) 14 days C) 21 days D) 7 days E) I month 16. Plot the n(1) vs. (in days), and indicate where it peaks. 17. Find the "area" under the curve of n(t) fromt = 0 to 1= 0. What is the interpretation of this "area"? 18. Find the derivative of arctan(x) with respect to x. 19. Find the mean value of the cos (x).
