If `A xxB = {(p , q), (p , r), (m , q), (m , r)}`, find A and B.

If A xx B={(p,q),(p,r),(m,q),(m,r)}, find A and B.

If A xx B={(p,q),(p,r),(m,q),(m,r)}, find A and B.

If P" "=" "{a ," "b ," "c} and A xxB" "=" "{(p ," "q)," "(p ," "r)," "(m ," "q)," "(m ," "r)} Q" "=" "{r} , form the sets P xxQ" "a n d" "Q xxP . Are these two products equal?

7. Let A= {p, q, r}. Which of the following is an equivalence relation on A?(a) R, = {(p, q), (q, r), (p, r), (p, q)} (b) R2 = {(1,9).(,p), (r,r). (9,7)} (c) Rz = {(p, p), (q,9), (r, r), (p, q)} (d) one of these

If (p)/( q - r) = (p + q)/( r) = (q)/( p) , Then find q : p : r

In Fig. 4.177, A C B A P Q . If B C=10 c m , P Q=5c m , B A=6. 5 c m and A P=2. 8 c m find C A and A Q . Also, find the area ( A C B): a r e a ( A P Q) . (FIGURE)
