In one sentence, describe what the following article is about: Two lines (including lines, line segments, or vectors) are perpendicular to each other if their slopes are negative reciprocals. Recall that a reciprocal is the multiplicative inverse of a given number. For a fraction, this can mean just "flipping" the fraction upside down. The following are examples of some numbers and their reciprocals: 5{\displaystyle 5} is the reciprocal of 15{\displaystyle {
rac {1}{5}}}. 23{\displaystyle {
rac {2}{3}}} is the reciprocal of 32{\displaystyle {
rac {3}{2}}}. 1{\displaystyle 1} is the reciprocal of 1{\displaystyle 1}. After you have calculated the slope of your vector, find the reciprocal of that slope. Using the example that was started above, the vector with components (3,5){\displaystyle (3,5)} has a slope of 53{\displaystyle {
rac {5}{3}}}. The reciprocal of 53{\displaystyle {
rac {5}{3}}} is 35{\displaystyle {
rac {3}{5}}}. If the slope of the original vector is positive, then the slope of the perpendicular vector will have to be negative. Conversely, if the slope of the original vector is negative, then the slope of the perpendicular vector will be positive. In the working example, the original slope was 53{\displaystyle {
rac {5}{3}}}, so the slope of the perpendicular vector must be 35{\displaystyle -{
rac {3}{5}}}. Knowing the slope is almost the final step. You then need just to rewrite the vector in its component form, using the "rise" and "run" components. For the working example, the new vector will be (5,3){\displaystyle (5,-3)}.
Summary: Recall the geometric definition of perpendicular slopes. Identify the reciprocal of the vector slope. Find the negative reciprocal. Write the new vector in component form.

In one sentence, describe what the following article is about: A pasta pot that is seven quarts (6.6l) or larger will allow you to cook a pound of pasta. Cooking with more than enough water also prevents clumping, sticky pasta. 7 to 5.6l) of water into your stockpot for each pound (0.4kg) of spaghetti. Surplus water will also allow the pasta to return to boiling quickly after you add your dry pasta. Using a lot of water is extremely important when cooking long pasta, like spaghetti or fettuccini. The long pasta needs room to move around the pot without sticking to the sides. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/fd\/Keep-Spaghetti-from-Sticking-Step-2Bullet1.jpg\/v4-460px-Keep-Spaghetti-from-Sticking-Step-2Bullet1.jpg","bigUrl":"\/images\/thumb\/f\/fd\/Keep-Spaghetti-from-Sticking-Step-2Bullet1.jpg\/aid4445569-v4-728px-Keep-Spaghetti-from-Sticking-Step-2Bullet1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class="mw-parser-output"><p>License: <a rel="nofollow" class="external text" href="https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/">Creative Commons<\/a><br>

Summary: Ensure you have a very large pasta pot. Pour five to six quarts (4. Add one tablespoon (18g) of salt to the water as the water comes to a boil. Don't add oil to the water.

In one sentence, describe what the following article is about: You won't maintain your resolve if you're trying to quit for your parents, your kids or even your spouse. Make up your mind that you're done getting high and you're done with the lifestyle. Narcotics Anonymous follows a 12-step program similar to Alcoholics Anonymous to help you to navigate life after opiates. In addition to following the 12 steps, you can go to meetings to talk to people who share your experience, and you'll be connected with a sponsor who you can talk to at any time as you fight to beat your addiction. Steer clear of people who will enable your lifestyle and friends from your druggie days. Also, avoid dealers or anyone else who used to give you access to drugs. The acute withdrawal may take anywhere from 3 days to 2 weeks. However, you can also experience something called Post-Acute Withdrawal Syndrome, or PAWS. PAWS often mimics other psychological disorders like depression, anxiety disorder and psychosis. People often experience lethargy, fuzzy thinking, memory problems, sleep disturbances and emotional swings. At the far end of the spectrum, people have thoughts of suicide. Get some support if you find yourself going through the symptoms of PAWS. If left untreated, the symptoms can lead you directly into relapse. You may find out that every part of your daily routine reminds you of the times that you took narcotics, but this will only be temporary. Also, it would be very beneficial to your sobriety to try to find new activities and new sober friends to add to your new life. These can help you down the right path. Of course, only start new things once you're starting to feel well enough and think you're up to it.
Summary:
Quit for yourself and no one else. Join Narcotics Anonymous or SMART Recovery. Associate with the right people. Prepare for the process of overcoming addiction to take a long time. Take life one small moment at a time.
