Suppose a right cylinder was bent into a U-shape and was compared to another right cylinder. What can be said about their volumes? A) They are the same since each cross section has the same area. B) There is not enough information to tell since they are not between parallel planes. C) The U-shaped has a greater value since the cross sections are bigger where it's bent. D) There is not enough information to tell since there is no information on cross section area.

Exercise: counting committees 0.0/2.0 puntos (calificable) we start with a pool of n people. a chaired committee consists of k≥1 members, out of whom one member is designated as the chairperson. the expression k(nk) can be interpreted as the number of possible chaired committees with k members. this is because we have (nk) choices for the k members, and once the members are chosen, there are then k choices for the chairperson. thus, c=∑k=1nk(nk) is the total number of possible chaired committees of any size. find the value of c (as a function of n ) by thinking about a different way of forming a chaired committee: first choose the chairperson, then choose the other members of the committee. the answer is of the form c=(α+nβ)2γn+δ. what are the values of α , β , γ , and δ ?
