For each series, find an explicit formula for the sequence of partial sums and determine if the series converges. (a)[infinity] n=1 1 2n (b)[infinity] n=1 1 n(n + 1) (c)[infinity] n=1 log n + 1 n (In (c), log(x) refers to the natural logarithm function from calculus.)

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
