Mark is in training for a marathon race. He has been training by running 10 miles each day. He will be increasing his running by this weekly formula: y = 10 (1.1 )x, where y is the number of miles he will run each day, x weeks from now. Compute the distance Mark will run each day for 52 weeks (one year) from now using the formula. Does this distance seem reasonable?

yes

no

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 ?
