Before the election, you want to determine the number of possible president/vice-president combinations for the sorority you bel
vichka [17]

Solution: We have to choose two positions president and vice president from eight people. So, we need to use the Permutations formula in order to find the possible number of combinations.

The number of possible combinations is:

8P2 =\frac{8!}{(8-2)!}

              =\frac{8\times7\times6\times5\times4\times3\times2\times1}{6\times5\times4\times3\times2\times1}

              =\frac{40320}{720}

              =56

Therefore the possible number of combination to select two positions from 8 people is 56

Use the function f(x) to answer the questions: f(x) = 2x2 − x − 10
Sidana [21]

Answer:

A. x = -2, 5/2

B. Minimum

Vertex: (1/4, -81/8)

C. Draw a concave up graph connecting the x-intercepts, vertex and the y-intercept

Step-by-step explanation:

f(x) = 2x² - x - 10

2x² - x - 10 = 0

2x² - 5x + 4x - 10 = 0

x(2x - 5) + 2(2x - 5) = 0

(x + 2)(2x - 5) = 0

x = -2, 5/2

Vertex: (h,k)

h = midpoint of the x-intercepts (due to symmetry)

h = (-2 + 5/2) = 1/4

k = f(1/4)

k = 2(1/4)² - 1/4 - 10 = -81/8

Vertex: (1/4, -81/8)

y-intercept: when x = 0

2(0)² - 0 - 10 = -10

Draw a concave up quadratic connecting thr following points:

(-2,0)

(0,-10)

(1/4,-81/4)

(5/2,0)
