Iffor twomatrices Aand B, then Amust be the inverse of B.
Consider the circular face in the accompanying figure. For each of the matrices A in Exercises 24 through 30, draw a sketch showing the effect of the linear transformation on this face.

In the financial pages of a newspaper, one can sometimes find a table (or matrix) listing the exchange rates between currencies. In this exercise we will consider a miniature version of such a table, involving only the Canadian dollar and the South African Rand . Consider the matrix
role="math" localid="1659786495324"
representing the fact thatrole="math" localid="1659786520551" is worth role="math" localid="1659786525050" (as of September 2012).
a. After a trip you have and in your pocket. We represent these two values in the vector . Compute . What is the practical significance of the two components of the vector ?
b. Verify that matrix fails to be invertible. For which vectorsis the system consistent? What is the practical significance of your answer? If the system is consistent, how many solutionsare there? Again, what is the practical significance of the answer?
Question: Show that if A and B are nxn transition matrices, then AB will be a transition matrix as well. Hint: Use Exercise 67b.
TRUE OR FALSE?
