Question: i is the following matrix nonsingular ii let c denote...

Question details

I Is the following matrix non-singular. II Let C denote the (k+1) x (k+1) matrix: where 1 denotes the vector of 1s and A is a k x k symmetric matrix of rank k-1 such that 1A- 0 Find C-1 III Find the inverse of the triangular matrix A: A-0 I J where I denotes the matrix n x n identity matrix, J denotes the n x n matrix of 1s, and 0 denotes the n x n matrix of 0s. IV Let: Find a, b, c so that P is an orthogonal Matrix
