Question 5 A club of 10 people wants to choose an executive board consisting of president, secretary, treasurer, and three other officers. In how many ways can this be done? [Input your answer as a number with no spaces.] (The following fuction f(x) is the cube root of 1/x - 1.) 3 For the function f(x)=°/1/x-1 and (fog)(x)=x2/3 find the function g(x) For the function g(x)= 4x3 14 + x3 and (fog)(x)=7/ x3 find the function f(x) For the function g(x)= x2 + x and (fog)(x)=1/x find the function f(x) Consider the set S of primes less than 15. List the set S (Input this as a list with no spaces, use commas.) How many subsets does the set have? (Hint: Consider the power set.) (Input this as a single number.) What is the maximum sum of a subset of S? (Input this as a single number.) If we sum the numbers in each subset, some of them are the same. Use the Pigeonhole principle (strong form) to find the number of sums that must be equal. (Input this as a single number.)
