Question

limit domain (11-x)P(x-5) is .....
x - > 9

Answer 1

P = permulation

Answer 2

I don't think I quite understand, is this supposed to be like a binomial coefficient?

Answer 3

I don't understand it neither.

Answer 4

\[\lim_{x\to9}\binom{11-x}{x-5}\]?

Answer 5

or maybe just\[\lim_{x\to9}\frac{(11-x)!}{(x-5)!}\]

Answer 6

I think the second.

Answer 7

yeah I think it is continuous at that point, so you should just be able to plug in x

Answer 8

wait a second , (11-9)P (9-5 ) = 2P4 That's impossible i think.

Answer 9

no it's not the answer is a fraction

Answer 10

So I should find the limit of the fraction ? 3!/4! 1*2*3/1*2*3*4
1/4

Answer 11

Seems right.

Answer 12

the numerator is not 3! though

Answer 13
