How to Solve a Quadratic Equation by Completing the Square ?

Make sure the leading coefficient is 1. This is the number in front of the X squared. If it isn’t 1, divide everything in the problem by the leading coefficient.

For instance,if you have 3 X squared, divide everything by 3. If you get fractions, don’t panic! You will just have to take your time to work with fractions through the problem.

Move the constant (the plain number with no X in it) over to the right side by adding or subtracting it from both sides. Do the opposite of whatever is in the original equation.

Find “b.” This is the number in front of the plain X, not the X squared. Write “b” down off to the side.

Make sure you include a negative sign if there is one in front of the “b”. Then divide it by two and circle Than square that and put a box around your answer.

Add the number in the box to both sides of the equation.

Now you are going to completely rewrite the left side of the equation. You are basically saying what could I foil (multiply out) that would make what I have now? Luckily, completing the square tells you how to do this so you don’t have to figure it out.

Draw parenthesis. Inside the parenthesis write “X + your circled number” if the number is positive or “X – your circled number” if it is negative Then put a “squared” on the outside of the parenthesis.

Now you can take the square root of both sides to solve for X. Because you are putting a square root sign in, you need to have two equations. One with a positive answer and one with a negative.

If you are able to take a square root of the right side, you will end up with two integer answers as in this problem.

If you cannot take the square root you need to simplify the radical in both equations and finish solving for X by adding/subtracting the remaining number on the left to both sides.

Many real world situations that model quadratic functions are data driven What happens when you are not given the equation of a quadratic function, but instead you need to find one?

In order to obtain the equation of a quadratic function, some information must be given Significant data points, when plotted,may suggest a quadratic relationship, but must be manipulated algebraically to obtain an equation.

Remembering: It is read minus b plus or minus the square root of b-squared minus four ac, all over two a It’s like driving a car once you know it, you won’t forget it: it takes you places fast.

Application – The “±” means you need to do a plus AND a minus, and therefore there are normally TWO solutions! You don’t have to choose, I’ll take both.

Command+Shift+4: brings up a selection box so you can specify an area to take a screenshot of,then save it as a file to the desktop
Command+Shift+4, then spacebar,then click a window: takes a screenshot of a window only and saves it as a file to the desktop

If you have just started to use Mac OS X you may not be familiar with the commands as it is totally different from Windows PC. One of the button that is not available on Mac is the Print Screen button.

How to do a outline

Posted on by

How to Make An Outline ?

Identify your topic and gather your materials Keep this as focused as possible-it shouldn’t be more than one sentence.

Decide the level of detail you want to include in the outline You can make your outline as a word or two under each subtopic and key point, or you can use sentences and phrases if this will make your final product easier to complete.

Figure out the most logical flow of information,beginning with subtopics that support your main topic.

Create enough subtopics to define all the major points you want to make.

The number or subtopics should be determined by how long your document or presentation is.

List the key points that you want to mention in support of each subtopic There should be at least two supporting items under each subtopic of the outline.

Review your outline and verify that all the points are covered.

This includes each subtopic being strengthened by the right key points, and most of all that you have accurately supported your topic.

Write your document or presentation Change your outline where needed once your have begun your actual piece of work.

Order in an Outline

There are many ways to arrange the different parts of a subject. Sometimes,a chronological arrangement works well At other times,
a spatial arrangement is best suited to the material.

The most common order in outlines is to go from the general to the specific This means you begin with a general idea and then support it with specific examples.

Why Do I Need an Outline?

Just as a builder doesn’t start-construction without a clear plan, you should also have an intellectual “blueprint” before writing your Historia essay.

Every structure, whether physical or intellectual, must have some underlying form or organization in order for it to stand It is unrealistic to think that you can make up your plan as you are writing your paper; the result would most likely be a disjointed hodgepodge.

And no matter how much effort you put into revision, the seams and cracks could never be totally smoothed away.

You can think of your outline as a kind of “virtual organization device” for your essay By making and tinkering with your outline you can mentally rehearse and try out different routes or thought sequences your paper could take.

Does one route lead to smooth interchanges (transitions), while others leave you hanging in a “can’t get there from here” impasse? Do some routes lead to “dead ends” or even train wrecks? You can find out where the pitfalls lie by experimenting with your outline—without risking serious damage to your actual essay.

How to Create a Main Mail Merge Document in Microsoft Word ?

Close all open Word documents and create a new one.

Go to the Tools menu and select Mail Merge.

Select Create and then Form Letters, and then click the Active Window button.

Click the Edit button and select the document you just created.

Go to the Insert menu, choose the third Date and Time (month, date, year) choice and click OK.

Press Return four times and begin typing the contents of your letter with only the salutation followed by a colon (for example, “Dear:”); do not include the name or address of any of the people to whom you are writing.

As you write the letter, leave blank any place you want to fill in later with a name or other personal information.

After you’ve written the letter, position the cursor where you want to insert the first “merge field,” or item to be filled in later (probably the name after “Dear:”), and then click Insert Merge Field on the Mail Merge toolbar.

Do this with each merge field until you’ve placed all of them in the correct position in the mail merge form letter.

Save the letter as Merge Main Letter.

Go to”How to Set Up a Mail Merge Data Source in Microsoft Word” to learn how to set up the names and addresses to be merged into your letter.

How to Do a Mail Merge to Email using Lotus Notes
Why do one?

In today’s”green” world, it makes much better sense to send out emails than letters but you still want to personalize them. Sadly, by itself Lotus Notes doesn’t support mail merge to email.

Of course, we know that outlook does (but then it lets anyone and anything send emails for you even when you don’t want them to).

how to do it in Notes?

OpenNTF:

The first port of call is OpenNTF (http://www.openntf.org/).

This place is full of great things but most of them are really badly documented Still, these guys give things away for free and they develop in their spare time, so we should be grateful for what we get.

There’s a great little project there called MailMerge Excel to Notes. Go there, click on releases and download the ZIP file.

Getting to the Code:

The installation is tricky though I’ve noted that since I asked the author about the install, it’s been updated (so maybe these steps are less necessary).

Unzip the files to somewhere on your hard drive (eg: C:\temp). The version I downloaded had three files;

MailMerge-CreateMerge.lss
MailMerge-SendMerge.lss
Lotus Notes Mail Merge Function.docx

The LSS files are not viewable in Notepad (not sure if this is a problem with those particular files) and I couldn’t find any means of importing them into an agent.

If you attach them to a mail message in Lotus Notes though, you can right-mouse click on them and choose VIEW.

From there, you can copy and paste them.

I copied and pasted both LSS files into text files for easy reference.

Creating the Agents:

1.Open your mailbox in Lotus Domino Designer.

2.Expand Code and double-click on Agents.

3.Click the Button marked New Agent

4. Give the Agent a Name, (Either Mail Merge\Send Mail Merge or Mail Merge\Create Mail Merge depending on which agent you’re putting in). You’re going to have to do this twice anyway.

5.Depending on how things go, you might end up with errors (I obviously did) These aren’t code errors but are either related to the way that the Notes viewer displays things or the way it pasted from Notepad.

To fix these errors,follow the little red circles with crosses in them.

Wherever you find a line which ends in & the notes client expects a line immediately below it My paste had blank lines so I just removed them all.

6.When the Agent is free of errors, press Ctrl+S to save. If it saves ok, you can close it and repeat steps 2 – 8 for the other LSS file.

How to Write an Internet Bibliography ?

Collect author title and publication information for all sources.
Create a document with 1-inch margins and use a plain 12-point font. Center the title, such as “Works Cited” or “References,” and doublespace paragraphs.
Choose a recognized style; the three most common style guides are MLA (Modern Language Association), APA (American Psychological Association), and the Chicago Manual of Style.
Format citations according to your chosen style:

Chicago:
Website: last name, first name middle initial (or name)”Article title” Website name URL (accessed month day, year).
Online database or journal: last, first. “Article title” Journal name volume,issue (year): page(s). URL (accessed month day,year).
Online media: performer, writer or creator Title, running time; title of source, format, URL (access date).

MLA:

Website: last, first”Article title” Website. Publisher, day month year. Web. day month year (The first “day month year”is the date the article was last updated.
The second “day month year” is the date you accessed the article).
Online database or journal: last, first. “Article title.” Journal volume, issue (year): pages. Database. Web. day month year.
Image: last, first name of artist. Title Date of creation. Institution where available, city Website title. Medium of publication. day month year.
Blog: editor, screen name, author or compiler name (if available). “Posting title” Name of site. Version number (if available) Sponsor or publisher Medium of publication. Date of access.

APA:

Website: last name, initials (year, month day). Article title. In website. Retrieved month day, year, from URL.
Online database or journal: last, initials (year). Article title. Journal, volume (issue), pages. Retrieved month day, year, from database title.
Electronic books: last, first initial Title. Retrieved from URL (if the work must be purchased, use “available from” instead of “retrieved from”).

Chapter of a web document or online book: last, first initial (Date of publication) Title of article. In title of book or larger document (chapter or section number). Retrieved month day, year, from URL.
Online book reviews: last, first initial (Date of publication). Title [review of book title] Title of website or publication. Retrieved from URL.

Online dictionaries and encyclopedias: last, first initial. Entry title Encyclopedia or dictionary title Retrieved month day, year, from URL.

Online presentations and lecture notes: last, first initial Title [file format] Retrieved from URL.

Italicize all book, video, audio, website and journal names If no authors are listed, list the article title first If publication date is unavailable, use no date (n.d.).

Alphabetize your entries. Create a hanging indent of five spaces or a half-inch by dragging the lower icon on your word processor’s ruler.

Using black ink, print the bibliography as the last page of your document. For an electronic copy, save your bibliography in a common format (.pdf, .rtf or .doc).

photo of using Internet sources

Internet bibliographies are most effective when citing non-print sources.
The addition of URLs in your citations allows a reader to verify facts and visit related websites.
When formatting your bibliography, use the style chosen by your professor or one of the three most common style guides: MLA; APA; or Chicago.
Research based on websites, online dictionaries and encyclopedias, ebooks,databases, magazines and journals give your audience easy access to your sources.
When using Internet sources, however, evaluate the quality of the sources and make sure the information you’ve gathered is accurate.

image of The MLA handbook sets specific citation guidelines for Internet sources.

The handbook of MLA style, published by the Modern Language Association, has recently changed some of its guidelines for citing Internet sources.
The handbook’s current version (the seventh edition) sets forth specific rules for creating citations for online resources; these guidelines help scholars and students follow a consistent, universal method that will always provide sufficient publication information, in a clear format, so that readers can find any Web sources mentioned .
