Hi there looking for help for some questions about maths..hope you have a good explan ation........

The LU factors of a matrix A are 10 21 Use the LU factors to find the solution at: of Am : b for a: The components of m : [ 1] are: 372 3:1 : Number 322 : Number \fThe QR factrorisation of a matrix A is 0.58 0.79 0.22 1.73 -1.62 0.58 -0.21 -0.79 0.8 0.58 -0.58 0.57 O 0 Find the vector ac that minimises | | r| | = || Axc - b|| for 1.13 b = 2.24 2.41 The components of a = 2 0 2 to two decimal places accuracy are: C1 = Number = NumberConsider the initial value problem for k : 0.3. Use one step of the improved Euler method to find an approximate value of y(0.1). Enter your answer to three decimal places accuracy. y(0.1) z Number Consider the system of first-order ordinary differential equations : 4311 + :92 311 ya : *m + tyg subject to 111(0) 2 0.7 and 312(0) 2 1.5. Use two steps of Euler's method to find an approximation for y1(0.5). Enter your answer to three decimal places accuracy. yl (0.5) a: Number
