It is on the basis of strengths that an entity enjoys a successful position among competitors. Strengths have to be maintained or improved. Example of SWOT Strengths Qualification, experience, social contacts, confidence, financial status, honesty, intellectualness etc.
Due to the nature of the mathematics on this site it is best views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width.
There will not be a lot of details in this section, nor will we be working large numbers of examples. The first special matrix is the square matrix. In other words, it has the same number of rows as columns. In a square matrix the diagonal that starts in the upper left and ends in the lower right is often called the main diagonal.
The next two special matrices that we want to look at are the zero matrix and the identity matrix. Here are the general zero and identity matrices.
These are matrices that consist of a single column or a single row. Arithmetic We next need to take a look at arithmetic involving matrices. If it is true, then we can perform the following multiplication.
Here are a couple of the entries computed all the way out. Determinant The next topic that we need to take a look at is the determinant of a matrix.
The determinant is actually a function that takes a square matrix and converts it into a number. The actual formula for the function is somewhat complex and definitely beyond the scope of this review.
The main method for computing determinants of any square matrix is called the method of cofactors. We can give simple formulas for each of these cases.
There is an easier way to get the same result. A quicker way of getting the same result is to do the following. First write down the matrix and tack a copy of the first two columns onto the end as follows.
What we do is multiply the entries on each diagonal up and the if the diagonal runs from left to right we add them up and if the diagonal runs from right to left we subtract them.
Here is the work for this matrix. Matrix Inverse Next, we need to take a look at the inverse of a matrix. Example 4 Find the inverse of the following matrix, if it exists.
In other words, we want a 1 on the diagonal that starts at the upper left corner and zeroes in all the other entries in the first three columns. If you think about it, this process is very similar to the process we used in the last section to solve systems, it just goes a little farther.
Here is the work for this problem. Example 5 Find the inverse of the following matrix, provided it exists. However, there is no way to get a 1 in the second entry of the second column that will keep a 0 in the second entry in the first column. We will leave off this discussion of inverses with the following fact.
Systems of Equations Revisited We need to do a quick revisit of systems of equations. The solving process is identical.
There will be no solutions. There will be exactly one solution. There will be infinitely many solutions.Note that when accountants write off a debt, the customer's obligation to pay remains. Writing off the debt serves only to improve the company's accuracy in accounting. Firms may also decide to write off a bad debt when it becomes clear for other reasons that the customer will never pay.
Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race, color, national origin, age, disability, and where applicable, sex, marital status, familial status, parental status, religion, sexual orientation, genetic information, political beliefs, reprisal, or because all or a part of an individual's income .
Note that the emphasis is on the lifetime stream of revenue and cost, not on the profit from a particular transaction. Although many companies measure customer satisfaction, most companies fail to measure individual customer profitability. Boston Consulting Group (BCG) Matrix is a four celled matrix (a 2 * 2 matrix) developed by BCG, USA.
It is the most renowned corporate portfolio analysis tool. It provides a graphic representation for an organization to examine different businesses in it’s portfolio on the basis of their related.
Cost-Volume-Profit Analysis In Brief Managers need to estimate future revenues, costs, and profits to help them They also use this information to monitor operations and evaluate profitability risk.
In this chapter, we combine revenues and costs in our analyses. CURRENT PRACTICE According to Jon Scheumann. A matrix helps you to organise your notes in a format that is easy to translate directly into your chapter draft. The idea is to identify themes you want to write about first so that you can read with more purpose and distill from the articles only what you need.
