number of ways A sit always sit next to B = AB together makes a single and

                                                                       therefore total number of arrangements for this  = 7+(AB) = 8  that is 8  persons sitting in circular manner

number of ways = (8-1)! =7! = 5040

likewise number of arrangements for A and C will be = 5040

Total number of ways such that A cannot sit next to B or C = total ways of 9 persons - total number of A always sitting next to B - total number of ways always sitting next to C  = 8! - 7!-7!

                                        = 40320- 5040-5040

                                        = 30240

What is the domain and range of a(w)=1.10w+0
german
The expression represents a straight line equation of the form y=mx+c. where m is the slope and c is the y-intercept. From the given expression,
m=1.10 and c=0
therefore since a(w)=1.10w+0 is a straight line equation, the domain of the equation will be:
(-∞,∞)
and the range will be:
(-∞,∞)
This is because the domain and range of the straight line is always (-∞,∞).
