If A=[(1,0),(-1,7)] and l is an identity matrix of order 2, then the value of k, if A^(2)=8A+kI , is :

Matrix A ha s m rows and n+ 5 columns; matrix B has m rows and 11 - n columns. If both AB and BA exist, then (A) AB and BA are square matrix (B) AB and BA are of order 8 xx 8 and 3 xx 13, respectively (C) AB=BA (D) None of these

Consider the points A=(1,2) and B=(3,-1) .Let M be a point on x+y=0 such that |AM-BM| is minimum.If S denotes area of triangle AMB then (8S)/(13) is.

A 8gm sample of iron are containing V% (by wt) of iron (Fe^(2+)) was present in 1L solution. This solution required V ml of a KMnO_(4) solution for oxidation of Fe^(2+) in acidic medium. If in another titration 20ml of same KMnO_(4) is required, for oxidaton of 20ml of H_(2)O_(2) in acidic medium. Find volume strength of H_(2)O_(2)

In this question, a word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabet as in two matrices given below. The columns and rows of Matrix-l are numbered from 0 to 4 and that of Matrix-II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g., 'B' can be represented by 00, 13, etc., and 'o' can be represented by 56, 68, etc. Similarly, you have to identify the set for the word 'TEAR'.

In each of the following questions, a word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in two matrices given below. The columns and rows of Matrix I are numbered from 0 to 4 and that of Matrix II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. 'E' can be represented by 01, 13, etc. and 'L' can be represented by 56, 77 etc. Similarly, you have to identify the set for the word given in each question.
