How many different committees of 4 people can be chosen from a group of 21? 143,640 5,985 1,9955

This is a combination - nCr = n!/(n-r)!r!

21!/(21-4)!4! =
21!/17!4! =
(21•20•19•18•17!)/17!•4•3•2 =
145640/24 =
5985

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
