Question

The set A consists of the points whose coordinates (x, y) are given by A = {(2 + 1)}, the set in point B is given by B = {(0, 0), (0, 1), (1, 2), (2, 5), (3, 6)}. Find: (i) n(B) (ii) A ∩ B

Answer 1

The set A consists of the point (2,1). The set B consists of the points (0,0), (0,1), (1,2), (2,5), and (3,6). The number of points in set B is 5. The intersection of sets A and B is the point (2,1).

Step-by-step explanation:

The set A consists of the point (2,1). The set B consists of the points (0,0), (0,1), (1,2), (2,5), and (3,6).

To find (i) n(B), count the number of points in set B, which is 5. To find (ii) A ∩ B (the intersection of sets A and B), we need to find the points that are common to both sets. In this case, the intersection is {(2,1)} since only one point is common to both sets A and B.
