Math Problem Statement

Give correct answer

Find the rank of the matrix [ [1, -1, 0, 2, 1], [3, 1, 1, -1, 2], [4, 0, 1, 0, 3], [9, -1, 2, 3, 7] ]

Solution

The rank of the given matrix is 3.

Here are five related questions for further practice:

  1. What is the definition of the rank of a matrix?
  2. How can we find the rank of a matrix using Gaussian elimination?
  3. What does the rank of a matrix tell us about its row or column independence?
  4. Can a matrix have a rank higher than its smallest dimension (number of rows or columns)?
  5. How does the determinant of a matrix relate to its rank?

Tip: The rank of a matrix is the maximum number of linearly independent rows or columns, which means it provides insight into the dimension of the space spanned by the matrix.
