B zero matrix. In the above picture, you can see, the matrix has 2 rows and 4 columns. a) n b) n-1 c) n+1 d) None of the above If a is a Matrix of Order 3 and |A| = 8, Then |Adj A| = Concept: Determinant of a Matrix of Order 3 × 3. If A is matrix of order m × n and B is a matrix such that AB' and B'A are both defined, then order of matrix B is +1 vote . Therefore, the order of the above matrix is 2 x 4. C determinant of A. If a matrix A is both symmetric and skew symmetric then matrix A is (a) a scalar matrix (b) a diagonal matrix (c) a zero matrix of order n × n (d) a rectangular matrix. Like matrix addition, the matrices being subtracted must be the same size. Answer/Explanation. Transcript. Featured on Meta Feature Preview: Table Support COMEDK 2007: If A is a square matrix of order 3 and | A | = 8, then | adj A |= (A) 8 (B) 82 (C) 1 / 82 (D) 1 / 8 . View Answer Answer: Transpose of A 23 If |A| = 0, then A is A 0. If a is a square matrix of order 3, with |a|=9,then write the value of |2.Adja| - 9312125 Also, check Determinant of a Matrix. 10. Orthogonal Matrix Properties Where ‘I’ is the identity matrix, A-1 is the inverse of matrix A, and ‘n’ denotes the number of rows and columns. See the below example to understand how to evaluate the order of the matrix. asked Mar 22, 2018 in Class XII Maths by vijay Premium (539 points) If A is matrix of order m × n and B is a matrix such that AB' and B'A are both defined, then order of matrix … Answer: c Explaination: (c), as it satisfies a ij = a ji, = -a ji and a ii = 0 Ex 4.5, 18 If A is an invertible matrix of order 2, then det(A−1) is equal to A. det (A) B. D order of A. Question 1 If A is any square matrix of order 3 × 3 such that || = 3, then the value of | | is ? B transpose of A. Matrix subtraction is performed in much the same way as matrix addition, described above, with the exception that the values are subtracted rather than added. Suppose A is a square matrix with real elements and of n x n order and A T is the transpose of A. If A is matrix of order m × n and B is a matrix such that AB' and B'A are both defined, then order of matrix B is asked Mar 22, 2018 in Class XII Maths by vijay Premium ( 539 points) matrices Browse other questions tagged linear-algebra matrices matrix-rank idempotents or ask your own question. If a matrix of transition probability is of the order n*n, then the number of equilibrium equations would be. Transcript. Check Answer and Solution for abo 24.9k views. 22 If A is a matrix of order(m - by - n) then a matrix(n - by - m) obtained by interchanging rows and columns of A is called the A additive inverse of A. If necessary, refer to the information and examples above for description of notation used in the example below. Order of Matrix = Number of Rows x Number of Columns. Then according to the definition, if, A T = A-1 is satisfied, then, A A T = I .
