Let c be the circle |z| = r where r > 1. show that |[log z / z2 dz| < 2 pi pi + log r / r and hence that the value of the integral approaches zero as r tends to infinity.

Fred has a total of 62 dvd and cd. if the number of cd is three more than two times the number of dvd, how many cd does he have?

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)

The equation represents the function f, and the graph represents the function g. f(x)=3(5/2)^x determine the relationship between the growth factors of f and g. a. the growth factor of g is twice the growth factor of f. b. the growth factor of f is twice the growth factor of g. c. the growth factor of f is 2.5 times the growth factor of g. d. the growth factor of f is the same as the growth factor of g.
