Roller Coaster Crew Ray and Kelsey have summer internships at an engineering firm. As part of their internship, they
get to assist in the planning of a brand new roller coaster. For this assignment, you help Ray and
Kelsey as they tackle the math behind some simple curves in the coaster's track.
Part C
6. Now that the curve pieces are determined, use those pieces as sections of a complete
coaster. By hand or by using a drawing program, sketch a design of Ray and Kelsey's
coaster that includes the shape of the g(x) and f(x) functions that you chose in the Parts A
and B. You do not have to include the coordinate plane. You may arrange the functions in
any order you choose, but label each section of the graph with the corresponding function
for your instructor to view.

Kevin's bank offered him a 4.5% interest rate for his mortgage. if he purchases 3 points, what will be his new rate?

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 ?
