what is permutation matrix and regular polygons


7. Show your work In the figure the two nontriangular polygons are regular polygons and the defects of the three polygons are as indicated. Find the measures of the angles of the triangle. 82=5 8 = 12 0
symmetry nected in a line of 9. Explain why only three types of regular polygons tessellate the plane. Choose the correct answer below. O A. In order for a regular polygon to tessellate the plane, its angle bisectors must intersect at 90, angles. OB. In order for a regular polygon to tessellate the plane, Its exterior angle measure must be a divisor of 360 Only three regular polygons have exterior angles that divide 360 Those polygons are the equilateral triangle,...
1. A permutation matrix P is a square matrix obtained by reordering the rows (or columns) of In. (a) Show that any permutation matrix can be written as a product of matrices of the form Pjk, where Pjk is the result of swapping Rj Rk on In. (b) Show that a permutation matrix satisfies the equation PTP In.
4) Think of regular polygons and their possible lines of symmetry. Do you notice a pattern in your answers??? If you find one, what is it? 1
(1 point) A square matrix is called a permutation matrix if it contains the entry 1 exactly once in each row and in each column with all other entries being 0. All permutation matrices are invertible. Find the inverse of the permutation matrix To 0 1 01 0 0 0 1 A= 0 1 0 0 L1 0 0 0 A- = Preview My Answers Submit Answers
this is a history of math problem so please work it out

1. (a) Factor the matrix into the form A= PT LU, where P is a permutation matrix: A = o 2 31 1 1 -1 . 10- 11 You may use the computer but each step of the factorization must be shown. In other words, this is to be done " by hand" but you can use the computer to do your basic arithmetic. (b) Determine the 2-norm of the matrix A using a built-in command on the computer.
Exercise 2. Given a permutation o E S. define a matrix P, E M. (F) by setting P.(1,j) = P.(.) = 806) 1 if i=0G) ifi 00) for all 1 Sij Sn. For example, ifo is the identity permutation, then P, (1) Show that det(P.) gn(a) for all o ES.. Deduce that the matrix P, is invertible, for all o ES (ii) Show that P.P. - Por for all 9,TES. Deduce that the matrix P, is orthogonal, for all o...
