Exercise 2. Let R (1, 3), (2, 5), (3, 7), (4, 9), (5, 11) be a relation in the set A ={1, 2, 3, 4 ,5 }Find the domain and range of R

If A=[(1,2),(3,-5)] then A^-1 is A. [(-5,-2),(-3,1)] B. [(5/11,2/11),(3/11, - 1/11)] C. [(-5/11,-2/11),(-3/11, -1/11)] D. [(5,2),(3,-1)]

If a, b and c are all different from zero and Delta = |(1 +a,1,1),(1,1 +b,1),(1,1,1 +c)| = 0 , then the value of (1)/(a) + (1)/(b) + (1)/(c) is

Image of (1, 2, 3) w.r.t a plane is (-7/3,-4/3,-1/3) then which of the following points lie on the plane (A) (-1,1,-1) (B) (-1,-1,1) (C) (-1,-1,1) (D) (1,1,-1)

If the sum of the series S=1+5/11+12/((11)^2)+22/((11)^3)+35/((11)^4)+.....oo can be expressed in the form of a rational number p/q in the lowest form, then the value of (p+q) equals (i) 2573 (ii) 2753 (iii) 2375 (iv) 2357
