A= [[-2,5,7] , [0,3,2], [9,4,1]] Find A' and |A|

If A=[(1, 2, 0 ),(3,-4, 5),( 0,-1, 3)] , compute A^2-4A+3I_3 .

How many 4's are there in the following series which is immediately followed by 5 but not immediately preceded by 3 ? 5 4 4 3 3 4 5 4 5 5 3 4 4 3 4 5 4 3 3 5 4 5 4 3 5 4 4 3 5 4 1) 0 2) 1 3) 2 4) 3 5) More than three

The following are the steps in finding the matrix B, if B + ({:(2, 3), (4, 5):}) = ({:(5, 4), (3, 2):}) . Arrange them in sequential order. (A) therefore ({:(p, q), (r, s):}) + ({:(2, 3), (4, 5):}) = ({:(5, 4), (3, 2):}) (B) Let B = ({:(p, q), (r, s):}) (C) ({:(p+2, q+3), (r+4, s+5):}) = ({:(5, 4), (3, 2):}) (D) P + 2 = 5, q + 3 = 4, r+ 4 = 3, s + 5 = 2 rArr p = 3, q = 1, r = -1, s = -3 (E) therefore B = ({:(3, 1), (-1, -3):})

In the following number series how many 4's are there which are immediately preceded by a pair of numbers whose product is more than the product of the pair of numbers immediately following 4 ? 2 3 4 5 3 3 4 7 6 5 2 4 3 2 4 5 1 4 2 2 4 8 4 9 7 4 0 9 4 3 2 1) 4 2) 5 3) 6 4) 2 5) None of these

In the following series how many 3's are there which are immediately precede by a pair of numbers whose product is more than the product of the pair of numbers immediately following 3 ? 2 6 5 2 3 4 5 3 3 4 7 6 5 3 4 3 2 4 5 3 4 2 2 4 8 4 9 7 4 0 9 4 3 2 4 1) 2 2) 3 3) 4 4) 5 5) None of these
