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.
Would you like more details on the steps involved or have any questions?
Here are five related questions for further practice:
- What is the definition of the rank of a matrix?
- How can we find the rank of a matrix using Gaussian elimination?
- What does the rank of a matrix tell us about its row or column independence?
- Can a matrix have a rank higher than its smallest dimension (number of rows or columns)?
- 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.
