Write an article based on this "Calculate the subtraction in parentheses. Square the value in parentheses. Add the numbers under the radical sign. Solve for d{\displaystyle d}."
article: By using the order of operations, any calculations in parentheses must be completed first. For example:d=(62)2+(41)2{\displaystyle d={\sqrt {(6-2)^{2}+(4-1)^{2}}}}d=(4)2+(3)2{\displaystyle d={\sqrt {(4)^{2}+(3)^{2}}}} The order of operations states that exponents should be addressed next. For example:d=(4)2+(3)2{\displaystyle d={\sqrt {(4)^{2}+(3)^{2}}}}d=16+9{\displaystyle d={\sqrt {16+9}}} You do this calculation as if you were working with whole numbers. For example:d=16+9{\displaystyle d={\sqrt {16+9}}}d=25{\displaystyle d={\sqrt {25}}} To reach your final answer, find the square root of the sum under the radical sign. Since you are finding a square root, you may have to round your answer. Since you are working on a coordinate plane, your answer will be in generic "units," not in centimeters, meters, or another metric unit. For example:d=25{\displaystyle d={\sqrt {25}}}d=5{\displaystyle d=5} units

Write an article based on this "Trim and layer your extensions if you have short hair. Go a shade lighter if you have short hair and want an ombre effect. Pay attention to the thickness of the wefts if you have thick hair. Tease your roots before adding the extensions to add volume. Don't be afraid to leave some wefts out if you have thin hair. Make sure that the wefts are not visible. Style your extensions if desired."
article: This may seem counterintuitive, especially if you are trying to make your hair look longer, but it will look more natural. If you clip in the extensions without blending them into your own hair, the difference in length will be obvious. Trim the extensions after you insert them into your hair. It would be a good idea to have a trained stylist do it for you. In most cases, you will want to match the extensions to your hair color. If you desire an ombre effect, consider going 1 to 2 shades lighter. If the ends of your hair are already lighter, you could match the extensions to them instead. You can use this step for longer hair as well. If you get extensions that aren't thick enough, the ends of your hair will look too thin compared to the rest of your hair. This will look unnatural and make it obvious that you are wearing extensions. This will give the wefts something to grip onto and prevent them from sliding off. It will also help give your hair a little extra volume. Tease each section just before adding the extension. To tease your hair, pull a thin section of hair away from your head, then run a comb under it in short strokes, starting from the middle and ending at the roots. This will often be the case if you bought thick hair extensions. If you use all of the extensions, the difference in volume between your hair and the extensions may be obvious. You may also create too much bulk, which could lead to visible wefts. Consider buying extensions designed for thin hair. They will give you length and volume while looking natural. You may have to adjust the positioning of the extensions. If you don't have enough hair covering them, the wefts may be visible. It would be a good idea to give your head a shake, and check for any wefts that are peeking through when your hair moves. The best places to position your extensions is anywhere below eyebrow level. This ensures that you have enough hair covering them. Curling your hair and the extensions will help give your hair even more volume. Whether you curl the extensions before or after you add them to your hair is up to you. Go with whatever is most comfortable for you. If your extensions are synthetic, check the package to see whether or not they are heat-resistant. If they are not heat-resistant, don't curl them.

Write an article based on this "Think about your posture and body language. Use props. Know when and how to use pictures. Select people in your audience, don't scan. Vary your tone. Don't forget about pauses! Conclude by restating your message and saying a simple, "Thank you."

Standing like you have a fig leaf over your crotch is not the way to give a captivating speech. Nor should you go the opposite way and lean over the podium. It's best to stand straight, feet shoulder width apart, and use your hands as naturally as possible. Your speech conveys a certain amount of emotion, right? (Correct answer: Yes.) Take those moments and move with them. You use your hands every day to express emotion -- this speech is no different. You're still communicating to people, just on a bigger scale. Though the scale is different, the gestures remain the same. For a great example of how to move on stage and use your hands while speaking, check out Bryan Stevenson's Ted Talk on Equal Justice. Have you heard about that TED talk where the woman is talking about schizophrenia and her own brain hemorrhage? No? Well, have you heard about that TED talk where the woman is talking about schizophrenia and her own brain hemorrhage and then she whips out a real human brain, spinal cord and all? You can hear the audiences jaws dropping in the video. Talk about painting a vivid picture. This should be used carefully, though. Don't whip out a different prop every sentence. Stick to one really effective prop, like the brain. Telling a story about your dad's last burning building he ran into? Take out his burned firefighter helmet. Talking about the time you ran into Will Ferrell at your local Starbucks? Whip out your autographed grande, coffee-stained cup when you get to the part about how you fainted after asking. Use them sparingly, but effectively. A powerpoint can be a great addition to a speech (for certain topics, at least). Just make sure you use them to your advantage! You want them to listening to you, not awe-struck by the pretty pictures. Take the time to practice delivering your speech while presenting the powerpoint in order to get the timing and technical aspects down. Use graphs to illustrate your points, especially if they're hard to understand. Pictures can be more memorable than just being told factoid, regardless of how pivotal it may be. Don't face the pictures when you're talking! You know what's on there -- keep delivering the speech to your audience, not the screen. A lot of people are under the impression scanning the audience is ideal -- and if that makes you nervous, just sort of scan the back wall. No! Resist! Instead, think of it as a one-on-one conversation. Make eye contact with a person over here, a person over there, etc. Draw them in one at a time instead of making them all feel glossed over. In general, sure, you should talk at a calm, understandable rate and speak with clarity. This should be your go-to. But to keep your audience awake and to keep your speech dynamic, vary it up. The parts you feel passionate about should be clearly emphasized! Speak loudly and with vigor! Pound your fist if you need to! And then there are parts that will feel more like a lullaby. And even parts that require pauses to let the emotion set in...AND THEN RAMPED BACK UP. It's a lot more effective verbally than over text. You get it. Show emotion in your tone, too. Don't be afraid to chuckle a bit or show a bit of grief or frustration. You're human. Your audience is looking for a human connection, not a robot spitting words at them. There's just as much power in the pauses as there is in the words. Think about the sentence, "Dihydrogen monoxide killed 50 million people last year. 50 million. Let that sink in." Now think about the sentence with pauses after each period. Gets a little more serious, doesn't it? Take your speech and literally write in the pauses if it'll help you. Draw a big ol' slash through the text to indicate a break. Once you have it down, you'll be able to feel where the pauses will go. " You've gone through the speech, no one's died, and now it's time for your conclusion. Keep it to the point, lock eyes with the audience, thank them, smile, and get off the stage. Take a deep breath. You did it. Next time you'll be giving a speech on how to give speeches. What were you so nervous about in the first place?
