If the rank of the matrix A= [(1,2,3,0),(2,4,3,2),(3,2,1,3),(6,8,7,alpha)] is 3 then a= (A) -5 (B) 5 (C) 4 (D) 4

If f(x)=x^2+4x-5 and A=[(1,2),(4,-3)] then f(A)= (A) [(0,-4),(8,8)] (B) [(0,-4),(8,8)] (C) [(1,1),(1,0)] (D) [(8,4),(8,0)]

If A=(3,5,7,8) and B=(7,8,9,10), then Find the value of (AcupB)-(AcapB) . The following are the steps involved in solving the above problem. Arrange them in sequential order. (A) AcupB=(3,5,,8,9,10) and A capB=(7,8) (B) Given A=(3,5,7,8) and B=(7,8,9,10) (C) (AcupB)-(AcapB)=(3,5,9,10) (D) (AcupB)-(AcapB)=(3,5,7,8,9,10)-(7,8) .

If A=[(2, 0,-3),( 4, 3, 1),(-5, 7, 2)] is expressed as the sum of a symmetric and skew-symmetric matrix, then the symmetric matrix is (a) [(2, 2,-4 ),(2, 3, 4),(-4, 4, 2)] (b) [(2, 4,-5),( 0, 3, 7),(-3, 1, 2)] (c) [(4, 4,-8),( 4, 6, 8),(-8, 8, 4)] (d) [(1, 0 ,0 ),(0 ,1 ,0),( 0, 0, 1)]

If A=|[-1,2,4],[3,1,0],[-2,4,2]| and B=|[-2,4,2],[6,2,0],[-2,4,8]| ,then find relation between A and B.

If the matrix A=[[1,2,3,0],[2,4,3,2],[3,2,1,3],[6,8,7,alpha]] is of rank 3 then alpha= (A) -5 (B) 5 (C) 4 (D) -4
