Express `{(x,y):x^(2)+y^(2)=25`, where `x,y inW}` as a set of ordered pairs.

A relation R is defined from the set of integer Z to Z as follows: (x,y) in Z hArr x^(2) + y^(2)=25 (i) Express R and R^(-1) as the set of ordered pairs. (ii) Write the domain of R and R^(-1) .

A relation R is defined on the set Z of integers as: (x,y)in Rhat Theta x^(2)+y^(2)=25. Express R and R^(-1) as the sets of ordered pairs and hence find their respective domains.

Let A={1,2} and B={2,4,6}. Let f={(x,y):x in A,y in B and y>2x+1. Write f as a set of ordered pairs.

A is a set of first 10 natural numbers and R is a relation from A to A defined as: (x,y) in R hArr x+2y=10 when x,y in A (i)Express R in the form of a set of ordered pairs. (ii) Find the domain and range of R. (iii) Find R^(-1) .

If (3/2+(isqrt(3))/2)^(50)=3^(25)(x+iy) , where x and y are reals, then the ordered pair (x,y) is given by

Let R be a relation in N defined by (x,y)in Rhat harr_(x)+2y=8. Express R and R^(-1) as sets of ordered pairs.

7(x-2y)^(2)-25(x-2y)+12

Let R={(x,y):|x^(2)-y^(2)|<1} be a relation on set A={1,2,3,4,5}. Write R as a set of ordered pairs.
