16) Calculus Professors Constante, Douglas, May, Perepelitsa, and Sosa each attempted to determine the value of the number 6 involved in the following definite integral equation: ( 6 sin ( z ) + 6 cos(7 ) + 5/x ) de = 0 Here are each of their conclusions: I. Professor Constante thinks b = 7 will work as an answer. II. Professor Douglas thinks b = will work as an answer. III. Professor May thinks b = 3 7 will work as an answer. IV. Professor Perepelitsa thinks b = 0 will work as an answer. V. Professor Sosa thinks b = will work as an answer. Which professor(s) found a correct answer? a) Only Professor Perepelitsa. b) Professors Constante, Douglas, and Sosa only. c) Professors Douglas and Sosa only. d) All five professors. e) Professors Constante, May, and Perepelitsa only
