Hi there looking for help for some questions about maths

A linear system of equations Arc : b has right-hand-side b : (5,12). You are given that the condition number of the matrix A is 446. If the right-hand-side vector b is changed to b : (5.012, 12), then the relative change in the solution cc would be expected to change by a factor of up to Number Enter your answer to at least one decimal place accuracy. The LU factors of a matrix A are 12 9 and Use the LU factors to find the solution ac of Axc = b for b = 4 14 2 1 The components of @ = are: = 3 XThe matrix 0.79 a a 0.79 is orthogonal when Enter your answer to three decimal places accuracy. You are given that the matrix is orthogonal in the following system of linear equations: 2 2 l 2 2 2 2 2 m. 2 _; l _; 1 2 2 2 2 2 $2 _ 2 2 _; _; 2 2:3 * 3 2 2 2 2 _5 2 2 _; _; \"34 2 2 2 2 The second component of the solution is $2- The OR factrcrisation of a matrix A is 0.58 0.79 0.22 1.73 1.62 0.58 0.21 0.79 0 U.8 0.58 0.58 0.57 0 0 Find the vector at that minimises Hr\" : H1113: E)\" for 1.13 b : 2.24 2.41 371 to two decimal places accuracy are: .2132 The components of m : [ 231 Number Number 5'?
