The board of directors of a corporation must select a president, a secretary, and a treasurer. In how many possible ways can this be accomplished if there are 19 members on the board of directors?

Step-by-step explanation:

Assuming one person can hold only one title.

19 ways to select the first position

18 ways to select the second position

17 ways to select the third position

19•18•17 = 5,814

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
