If A(4, -3), B(3, -2) and C(2, 8) are the vertices of a triangle, then its centroid will be
(-3,3)
(3,3)
(3,1)
(1,3)
Let the centroid of the triangle be (x, y).
The centroid of a triangle is given by (x1+x2+x33,y1+y2+y33) x=4+3+23=3
y=−3−2+83=1
Let A = {1, 2, 3}, B = {1, 3, 5}. If relation R from A to B is given by
R = {(1, 3), (2, 5), (3, 3)}. Then, R−1 is
