2) How many ways can 8 runners win 1st, 2nd, or 3rd
a. 8 b. 24 c. 56 d. 336
3) Which equation is equivalent to this y = 3x^2 + 6x - 7
a. y = 3(x+1)^7 - 4
b. y = 3(x-2)^2 - 8
c. y = 3(x+1)^7 - 10
d. y = 3(x-1)^2 + 10
4) Sector central angle of 7pi/12 radius of 6, what is the area of the sector?
5) which has solutions of x = 3 and x = -1/2
a. 2x^2 - 7x - 3 = 0
b.2x^2 + 7x - 3 = 0
c 2x^2 - 5x - 3 = 0
d. 2x^2 + 5x - 3 = 0
