Find the minor of a_23 in |(2,-3,5),(6,0,4),(1,5,-7)|

Show that [(2,-1,3),(-5,3,1),(-3,2,3)] is inverse of the matrix [(-7,-9,10),(-12,-15,17),(1,1,-1)]

The cofactor of a_13 in {:|(2,-3,5),(6,0,4),(1,5,-7)| is

Which of the following relations are functions form A = (1,3,5,7,9) to B = (1,2,3,4,5). f= ((3,1), (5,1), (7,1), (9,1))

If A = {:[(1,1,-2),(2,1,-3),(4,5,6)] , find |A|.

Show that {:[(4,1),(2,7)][(2,1),(3,4)] ne [(2,1),(3,4)][(4,1),(2,7)]

Let X = {1, 2, 3, 4} and Y = {1, 3, 5, 7,9} . Which of the following is relations from X to Y (i) R_(1) = {(x, y):y=2+x,x inX, yinY} (ii) R_(2) = {(1, 1), (2, 1), (3, 3), (4, 3), (5, 5)} (iii) R_(3) = {(1, 1), (1, 3), (3, 5), (3, 7), (5, 7)} (iv) R_(4) = {(1, 3), (2, 5), (2, 4), (7, 9)}

Consider the pattern shown below: {:(" Row ",1,1,,,),(" Row ",2,3,5,,),(" Row ",3,7,9,11,),(" Row ",4,13,15,17,19):}etc. The number at the end of row 60 is
