Choose the matrix after performing the elementary row operation 5R 1 + R 2 on the matrix ( 1 4 3 2 0 1 1 -1 2 ) . => ( 1 -4 3 2 0 1 -11 -1 2 ) or ( 11 14 3 2 0 11 1 -1 2 ) or ( 1 4 3 7 20 16 1 -1 2 ) or ( 1 4 13 2 10 1 1 -1 ..

Perform the elementary row operation (-1)R 3 + R 1 on the matrix ( 3 1 5 1 -1 2 0 1 3 ) . => ( 3 1 0 1 -1 2 0 1 2 ) or ( 3 0 2 1 -1 2 0 1 3 ) or ( 3 1 5 1 -1 2 0 1 2 ) or ( 3 1 5 0 1 2 0 1 2 )..

Let R i denotes the i t h row of the matrix A = [a i j ] then the elementary row operations on the matrix A are defined as: 3. R i g R i + kR j means multiply each element of j t h row by k and add it to the corresponding elements of i t h row. The corr..

In nature, food chain relationships are not isolated. They are very complex, as one organism may form the food source of many organisms. Thus, instead of a simple linear food chain, there is a web like structure formed by these interlinked food chains. Such interconnected matrix of food c..

Movements and locomotion takes place as a result of co-operation between the muscle and skeletal system, hence the study of both is necessary. Skeletal system in humans is formed by bones and cartilages. It helps in protection of delicate visceral organs, mechanical support, moveme..
