Answer the Question number 8 2A — 3B 7 , then is • If 01 dements in a matrix iS 60. many Order 12 (CJ 24 Hone these 3. 5. Matrix A has x rpws and x • 5 columns. Matrix B has y and 11 — •hen - If .42 = A. AJ4 is equal • If the oi n mStrices of n is equab to • 27 and 15A is equal to the matrix 377 none of those then the value (D) 378 s. If A is a skew symmetric matrix such thai AXA (A)-AT AAT and det(A) then - (A) Every element Of A' is equai to it's c&iactor. = then (n e N) is to • 1B) Every element of A and it's cc-factOr are additive inverse oi each other, (C! ELery element of A and.ifs cefgctoi ere multi*cative inverse of" each other.' (D) None oi th%e Which of the following is an orthogonal matrix - 6/7 3/7 c; 2/7 1=3/7 2/7 3/7 -2/7 3/7 6/7 -3/7 2/7 -3/7 6/7 6/7 3/7 6/7 2/7 -3/7 6/7 -2/7 3/7 6/7 -2/7 3/7 il A is an orthogonal matrix & -6/7 2/7 1, then AT is equai to • 77
