Article: Every vector can be numerically represented in the Cartesian coordinate system with a horizontal (x-axis) and vertical (y-axis) component. It is written as an ordered pair v=<x,y>{\displaystyle v=<x,y>}. For example, the vector above has a horizontal component of 3 and a vertical component of -5, therefore the ordered pair is <3, -5>. When you draw the horizontal and vertical components, you end up with a right triangle. The magnitude of the vector is equal to the hypotenuse of the triangle so you can use the Pythagorean theorem to calculate it. The Pythagorean theorem is A2 + B2 = C2. "A" and "B" are the horizontal and vertical components of the triangle while "C" is the hypotenuse. Since the vector is the hypotenuse you want to solve for "C". x2 + y2 = v2 v = (x2 + y2)) Using the equation above, you can plug in the numbers of the ordered pair of the vector to solve for the magnitude. For example, v = ((32+(-5)2)) v =(9 + 25) = 34 = 5.831 Don't worry if your answer is not a whole number. Vector magnitudes can be decimals.
Question: What is a summary of what this article is about?
Determine the components of the vector. Draw a vector triangle. Rearrange the Pythagorean theorem to calculate the magnitude. Solve for the magnitude.
Article: A negative review can be tough to swallow and you may start to feel angry or defensive. You may also react emotionally if you were not expecting the review to be so poor. Resist the urge to get upset, yell, or shout. Instead, try to stay calm and collected. If you are getting a negative performance review, you may react by simply nodding your head while the reviewer discusses your performance review. Try to maintain a neutral facial tone and maintain eye contact with the reviewer. You should also try to display open body language, where you keep your body relaxed and your hands at your sides or in your lap. Try not to fold your arms over your chest or fidget with your clothing, as these are signs of closed body language. If you are reading a negative review of your business online or getting an in person complaint from a customer, you should try to relax your body and take a deep breath before responding. During the review, acknowledge any negative physical reactions that you are having, such as an increased heart rate, sweating, or a turning sensation in your stomach. These reactions are normal. Remind yourself that only you can feel these and the person who is reviewing you is unlikely to notice them. Acknowledge these physical sensations silently to yourself and then continue to focus on the conversation. Though it may be difficult to listen to the review, try to pay attention to what the reviewer or the customer has to say. Focus on their words and try to pay attention to any information they are giving you during the review. This will allow you identify and address your performance issues later. You may take out a paper and pen to write down notes on what the reviewer or customer is saying to you. You may also ask for a copy of your performance review and write notes in the margins. Try not to interrupt the reviewer or customer when they are speaking. The more information you absorb, the better you can address them and improve your performance. If you get distracted or get defensive during the review, you may miss an opportunity to understand the review and identify your performance issues. Be professional and accept the feedback in the review. Refusing to own up to the review will only show the reviewer or the customer that you are not willing to work on your issues or try to improve. If you are getting a negative performance review, you may be required to sign the review to acknowledge you have read it and understood it. Sign or initial the review willingly to show the reviewer that you are able to own up to the review and acknowledge your performance issues. You can also own up to the review by saying, "Thank you for taking the time to share this information with me. I take this review seriously and would like to work on improving my performance."
Question: What is a summary of what this article is about?
Stay calm. Listen closely to the feedback. Own up to the review.
Article: By default, your computer starts up by reading the operating system information from its built-in hard drive. You can change this by telling it to prioritize plugged-in USB items over the built-in hard drive. The settings for your computers boot behavior are in a menu called the BIOS, which is a pre-startup menu you can access by pressing a key specific to your computer model as your computer turns on. In order to boot from a USB flash drive, the flash drive must be set up as a bootable item, and it must have a disk image (ISO) file with an operating system or similar service installed on it. The key that you press to access the BIOS varies depending on your computer manufacturer and model. You can look up your computer's BIOS key by typing your computer's manufacturer and model name, along with "bios key", into a search engine and reviewing the results, or you can consult your computer's manual if you still have it. Most computers use one of the function keys (e.g., F12) as the BIOS key, though some computers will use the Esc key or the Del key. The USB flash drive should plug into one of the rectangular USB ports on your computer's housing. On a laptop, the USB ports are typically on the sides of the housing, while desktop computers typically have the USB ports on the front or back of the tower. . If your flash drive isn't already bootable, use the Command Prompt or one of the Windows installation tools to make it so. Copy the ISO file you want to boot from by clicking it once and then pressing Ctrl+C, then open your flash drive and press Ctrl+V to paste in the file. For example, if you're attempting to install or use Ubuntu Linux from the flash drive, you would paste the Ubuntu ISO file into the flash drive's window. Skip this step if you created a bootable USB using the Windows 7 or 10 installation tool. Before you proceed with accessing the BIOS, you'll want to save any open work and then close any open programs to avoid losing your progress.
Question: What is a summary of what this article is about?
Understand how booting from a USB works. Determine your computer's BIOS key. Plug your USB flash drive into your computer. Make the USB flash drive bootable Add the file to which you want to boot to the flash drive. Save and close any open work.
