Members of the Arts Faculty, love playing around with anagrams – letter combinations that can generate a number of different words. For example, the letters A, C, D, E and R can form the words CADRE, CARED, CEDAR or RACED. More mathematically inclined members of the Arts Faculty know that permutation matrices can be used to rearrange the letters in a word. o 0 0 0 1 0 0 10 0 A and matrix P = 1 0 0 0 0 then what word is formed by 0 10 0 0 0 0 0 10] E (a) If matrix W the matrix product Px W? (b) In the matrix provided below, fill in the element values for matrix Q so that the matrix product Qx W gives the word SLATE. L (c) Explain why the matrix product Q4 x W gives the matrix A

A factory manufactures three products (doohickies, gizmos, and widgets) and ships them to two warehouses for storage. The number of units of each product shipped to each warehouse is given by the matrix A=[20015010075100125] (where aij is the number of units of product i sent to warehouse j and the products are taken in alphabetical order). The cost of shipping one unit of each product by truck is $1.50 per doohickey, $1.00 per gizmo, and $2.00 per widget. The corresponding unit costs to ship by train are $1.75, $1.50, and $1.00. Organize these costs into a matrix B and then use matrix multiplication to show how the factory can compare the cost of shipping its products to each of the two warehouses by truck and by train.
