Problem: Article: Some math problems will not specify values of distance, but will tell you how long an object was moving and how fast it was moving. You can calculate displacement using these time and speed values. In this case, the formula would be: S = 1/2(u + v)t. U = the object's initial velocity, or how fast it started going in a certain direction. V = the object's final velocity, or how fast it was going at its last location. T = the time the object took to get there. For example: A car is traveling down the road for 45 seconds (time taken). The car turned west at 20 m/s (initial velocity) and by the end of the street, it was traveling at 23 m/s (final velocity). Calculate the displacement based on these factors. Now that you know how long the car drove for, how fast it moved in the beginning, and how fast it was moving in the end, you can find the distance from the initial location to the final location. Your formula will look like this: S = 1/2(20 + 23)45. Remember to follow the order of operations, otherwise displacement will turn out to be a completely different value. For this formula, it's okay if you accidentally switch initial and final velocity. Since you will be adding these numbers first, it doesn't matter where they are in the parentheses. For other formulas, however, switching initial with final velocity will give you a different displacement value. Your formula will look like this: S = 1/2(43)45. First divide 43 by 2, which will give you 21.5 Then multiply 21.5 by 45, which should give you 967.5 meters. 967.5 is your displacement value, or how far your car is from its original spot.
Summary: Use this formula when the problem specifies the object's velocity and time taken. Input the values for velocity and time into their respective variables. Calculate the formula once you have input the values into their correct places.

INPUT ARTICLE: Article: It's at https://www.whatsapp.com/. You can download WhatsApp's desktop version from this site. This option is toward the bottom of the webpage. It's on the right side of the page. Clicking this button will prompt the WhatsApp setup file to download, though you may first have to select a download location. It will likely be in your computer's default "Downloads" folder (e.g., the desktop). Once it's done, you'll see the WhatsApp icon, which is a white phone on a green background, on your desktop. A white window with a green illustration will appear while WhatsApp is installing. Doing so will launch WhatsApp's login page, which has a black-and-white checkered box (this is a QR code). If you don't have WhatsApp on your phone yet, you'll need to install it on your iPhone or Android before continuing. Depending on your phone, the path to open the QR scanner will be as follows: iPhone - Tap Settings in the bottom-right corner of your screen, then tap WhatsApp Web/Desktop near the top of the screen. Android - Tap , then tap WhatsApp Web at the top of the menu. After a brief moment, WhatsApp will scan the code, which will give your computer permission to log into WhatsApp. You should now be able to use WhatsApp on your computer! If the QR code has expired, click the arrow in the middle of it to refresh the code. If the code won't scan, make sure that all of the QR code is displayed on your phone's screen--you may need to increase the distance between your phone and your computer screen.

SUMMARY: Go to the WhatsApp website on a computer. Click Mac or Windows PC. Click the green DOWNLOAD button. Wait for the setup file to finish downloading, then double-click it. Wait for WhatsApp to finish installing. Double-click the WhatsApp icon if WhatsApp doesn't open. Open WhatsApp on your phone. Open the WhatsApp code scanner. Point your phone's camera at the QR code.

In one sentence, describe what the following article is about: Make sure you know all the different models, so you know what you're looking for when you get to the dealership. The 1 Series is a rear-wheel drive four-seat car that is best for consumers who are looking for a small, fast luxury vehicle. For the best-selling BMW, you'll want to look for the 3 Series. This is also a small car, but it comes in rear-wheel and all-wheel drive. You can a get a sedan (E90), wagon (E91), coupe (E92), and convertible (E93). This is also a high powered vehicle, but is also known for handling well. If you're looking for something cheaper, consider the older (E46) coupe or cabriolet. The 5 Series is a mid-size sedan that is mostly known as a luxury vehicle. It is available in all-wheel drive. Some even have diesel engines and save costs in fuel consumption, although exhaust parts may need to be replaced more often For the largest sized vehicle, you'll want to look for the 7 Series, which is a luxury sedan that comes with leather seats and often wood trim. This is made for people who can be driven around by people like chauffeurs, otherwise don't waste your cash on it. Based on the 3 Series, the X3 is a small SUV that has a lot of space for hauling whatever you wish. It works well if you have a small family and "occasionally" need to tug a giant amount of items. The most expensive BMW besides the 7 Series is the X5. It's the largest SUV and can be pricey to maintain as well as buy. Be careful of the X5 as they are greatly unreliable and costs start and go upward of $5,000. BMWs are great cars, but they lose value quickly. This can especially be a problem if you plan on reselling your used BMW later on. BMWs do not maintain their value for long. With each passing year, your car loses value at a larger rate than other similarly priced luxury vehicles. Some BMWs don't depreciate as quickly as others. While the 7 Series depreciates especially quickly, the 1 Series and X5 do not. Keep this in mind when choosing the model of BMW you want to purchase. High depreciation cars can also mean that you can find an older BMW for less. The difference between a 3- and 6-year old BMW can be rather large. BMWs can be expensive to maintain, because of general upkeep, as well as costly repairs and issues with reliability. BMWs are expensive to maintain. They require higher quality gasoline, oil, and tires than many other vehicles. Additionally, the labor costs for BMWs are usually higher because of the way they're engineered. This can be avoided by going to second or even third hand repair centres. If the BMW was made before 1999, the car can be serviced by any mechanic specialized, non-specialized or even by the owner (you). Repairs for a BMW can be pricey. It's not hard to find a shop that specializes in these vehicles, but in their Vehicle Monitoring Systems. Local dealerships are usually expensive for repairs, so having a BMW-specialized repair store near you is important for keeping costs down. While BMWs (with the exception of the X5) are generally reliable, they do occasionally need repairs. Some of their reliability issues are due to the use of plastic parts and the expensive electronics that make up the interior of the car. Certain BMW models are known for having common problems. Make sure you know any specific problems with your model. Some of the most common problems for BMWs include: Electrical issues. The BMW has many complex electronics both inside and outside the vehicle. BMWs occasionally have issues with the battery, fuses, and the key control system. Additionally, some internal electronics like power windows and power steering are problematic in BMWs. As mentioned earlier most of these systems are managed and controlled by the vehicle's iDrive System. Engine issues. Since many of the BMWs have turbocharged engines, engine problems are common with these cars. Some issues including stalling, difficulty while idling, and a rough ride. On a second-generation X5, the engine replacements can cost around $5,000. Rattles. BMWs can have strange noises coming from inside or outside the vehicle. These may simply be annoying, but they could also indicate a problem with the vehicle.
Summary:
Research the different types of BMWs. Be aware of potential depreciation with a used BMW. Know about the costs of maintaining a used BMW. Read about the potential issues with each model car.
