What is the number of possible permutations of 9 objects taken 4 at a time?

A.
120
B.
126
C.
3,024
D.
362,880

Step-by-step explanation:

Permutation has to do with arrangement. If 'n' object is to be arranged taking 'r' at a time, this can be done in number of ways where;

Based on the conclusion above, the number of possible permutations of 9 objects taken 4 at a time will be expressed as .

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

answer:

f(5/2) = 10/3

i hope this you!
