Problem: Write an article based on this summary: Wash your face with cold water. Soak your eyes with a cold washcloth. Cover your eyes with cold spoons. Tap your eyes gently. Massage the bridge of your nose. Lie down with your head elevated. Apply chilled face cream.

Answer: If you're in a rush or a public place, visit the bathroom for a quick refresh. Fold a paper towel twice to make a neat square, then soak it in cold water. Press it lightly against your eyelids, for fifteen seconds each. Look upward and place the towel just beneath your lower lashes, pressing gently for another fifteen seconds on each eye. Let your skin eye dry. Repeat if necessary. Do not scrub your eyes or use soap. Some people like to mix in about 1 tsp (5 mL) table salt in 1 cup (240 mL) ice water. Don't try this if you have red, irritated skin. Wet a soft, fluffy cloth with ice cold water. Wring it out, then fold the cloth over your eyes for about ten minutes. The cold should constrict the blood vessels around your eyes, reducing the swelling. You can get similar results with an ice pack or a bag of frozen peas. You can even make your own cold pack by stuffing a sock full of raw rice and tossing it in the freezer. Don't use a bag of large, chunky vegetables, since it can't mold around your eyes. Choose a pair of metal teaspoons that fit closely over your eyes. Freeze them for about two minutes or keep them in the fridge for 510 minutes. Place them over your eyes with slight pressure. Leave them until they warm up. If you have time, freeze six spoons instead. Replace the spoons with a new, cold pair once they warm up. Stop after the third pair to avoid skin damage from prolonged cold. You can also try adding cold teabags to your eyes to reduce puffiness. Lightly tap the puffy areas of your eyelids, using your ring finger. This can stimulate blood flow, moving pooled blood out of the area. Close your eyes and massage the upper area of your nose. Focus on the skin to the right and left of the nose, where a pair of glasses would rest. This can relieve sinus pressure, which may have built up as you were crying. Place two or three pillows underneath your head to keep it above the rest of your body. Lie with your neck straight, close your eyes, and relax. Even a short break can lower your blood pressure. Refrigerate moisturizing face cream for about ten minutes, then rub gently into skin. The cold will treat puffiness, while the cream will soften and brighten your skin. Specialized eye creams are controversial. It's unclear whether they are more effective than normal face cream. Avoid creams that contain fragrance or mint. These may irritate your skin.

Problem: Write an article based on this summary: Find the first derivative of the revenue function. Set the derivative equal to 0. Solve for the number of items at the 0 value. Calculate the maximum price. Combine the results to calculate maximum revenue. Summarize the results.

Answer: In calculus, the derivative of any function is used to find the rate of change of that function. The maximum value of a given function occurs when the derivative equals zero. So, to maximize the revenue, find the first derivative of the revenue function. Suppose the revenue function, in terms of number of units sold, is R(q)=500q150q2{\displaystyle R(q)=500q-{
rac {1}{50}}q^{2}}. The first derivative, therefore, is: R(q)=500250q{\displaystyle R^{\prime }(q)=500-{
rac {2}{50}}q} For a review of derivatives, see the wikiHow article on how to Take Derivatives. When the derivative is zero, the graph of the original function is at either a peak or a trough. This will be either the maximum or minimum value. For some higher level functions, there may be more than one solution to the zero derivative, but not a basic price-demand function. R(q)=500250q{\displaystyle R^{\prime }(q)=500-{
rac {2}{50}}q} 0=500250q{\displaystyle 0=500-{
rac {2}{50}}q} Use basic algebra to solve the derivative for the number of items to sell where the derivative is equal to zero. This will give you the number of items that will maximize the revenue. 0=500250q{\displaystyle 0=500-{
rac {2}{50}}q} 250q=500{\displaystyle {
rac {2}{50}}q=500} 150q=250{\displaystyle {
rac {1}{50}}q=250} q=50250{\displaystyle q=50*250} q=12,500{\displaystyle q=12,500} Using the optimal number of sales from the derivative calculation, you can enter that value into the original price formula to find the optimal price. p=500150q{\displaystyle p=500-{
rac {1}{50}}q} p=50015012,500{\displaystyle p=500-{
rac {1}{50}}12,500} p=500250{\displaystyle p=500-250} p=250{\displaystyle p=250} After you have found the optimal number of sales and the optimal price, multiply them to find the maximum revenue. Recall that R=pq{\displaystyle R=p*q}. The maximum revenue for this example, therefore, is: R=pq{\displaystyle R=p*q} R=(250)(12,500){\displaystyle R=(250)(12,500)} R=3,125,000{\displaystyle R=3,125,000} Based on these calculations, the optimal number of units to sell is 12,500, at the optimal price of $250 each. This will result in a maximum revenue, for this sample problem, of $3,125,000.

Problem: Write an article based on this summary: Exchange information. Talk to witnesses. Take pictures.

Answer: Get the names and phone numbers of all the other drivers involved in the traffic accident. Write down the make, model, year and license plate number of each vehicle. Be sure to obtain all insurance information including the company, policy number and any insurance agent contact information the driver can provide. Be polite, but do not apologize. If you say, "I'm so sorry I hit you," you may be admitting legal liability for the accident. Try not to admit guilt unnecessarily like this, as it may not be clear who was at fault in the immediate aftermath. Be wary of identity theft. Criminals sometimes stage fender-benders in order to obtain the information needed to steal another motorist's identity. Never give out your social security number or let another driver take a picture of your driver's license. For safety reasons, don't provide your home address, either. Obtain names and contact information for any witnesses of the accident. Write down their account of what happened and make sure they agree to let your attorney or insurance agent contact and question them. They may be helpful if the other driver disputes your account of the accident. Photograph damage to your car and the other vehicles involved in the accident. Also take photos of the accident location and the people involved. This will help document the damage when you submit an accident claim to your insurance company. It will also help protect you in the event the other motorist claims more serious injury or car damage than actually occurred.

Problem: Write an article based on this summary: Be proactive. Keep in touch. Don't be materialistic. Do things "just because". Strive to be yourself around her. Let her know that she's valuable to you.

Answer:
Like the vast majority of human beings, most girls won't want to ask to be treated well - they'll want you to spontaneously treat them well. If your girlfriend constantly has to ask for the things she likes in your relationship - like for you to hold her hand, listen when she talks, remember her birthday, and so on - these special things are robbed of the joy they might otherwise bring. This can even make her feel isolated or needy. So try to stay on the ball - make an effort to treat your girlfriend with respect without her having to ask you. It's hard to be a steady presence in your girlfriend's life (and vice versa) if you rarely talk to her. Though every couple will have a different natural "rhythm" of communication, generally, you should try to meet, call, or, at the very least, text your girlfriend once or twice a week, if not more. This should stem from a natural urge to want to know what she's been up to - what minor accomplishments she's made in the last few days, what challenges she's faced, and so on. Be sure to contact your girlfriend on your own - don't just respond to her calls and texts. Taking the initiative to make that crucial first contact with your girlfriend demonstrates that you want her as much as she wants you. Nothing is less romantic than a man who loses sight of what's really important in life in favor of his money or possessions. Your girlfriend should always take precedence over material pleasures. For instance, don't skip your anniversary dinner to wax your new car. Don't neglect your girlfriend for weeks to play an addictive video game. Don't devote your every waking hour to your work. Keep your life in perspective - genuine love is a longer-lasting source of joy than any material gains you can ever hope to make. This being said, a good girlfriend will never willingly ask you to do things that are bad for your financial health. Though the mythical "gold-digger" is much rarer in real life than popular culture may lead you to believe, beware of women that pressure you into buying expensive gifts. It's normal for a man to show he cares for his girlfriend by celebrating birthdays, holidays, anniversaries, and so on with her. It's exceptional for him to show that he cares on the days between these big events. Take your girlfriend by surprise. Celebrate your relationship for no other reason than that you cherish it. This doesn't necessarily have to mean booking a fancy, expensive night out - a simple love note, a rose, a sweet text message, and other things like this can let her know that you are thinking of her and care for her. One of the goals of any good relationship should be for both partners to reach the point where neither has to put on a "nice" front for the other. Within the context of your relationship, you should be able to truly be "you" and not one of the characters you adopt for work, school, etc. This won't happen overnight, but it is something that has to happen for a great relationship to develop. Sometimes this may mean being truthful about negative emotions that, for whatever reason, you can't express during your daily life. Be honest and open about these emotions - they're part of the real you - but don't let them become the only topic of conversation in your relationship. This goes far beyond everyday compliments, which can become rote and dull if you repeat them too often. Instead, when you want to make your girlfriend feel amazing, be specific, drawing examples from your personal history and attempting to genuinely express your inner thoughts. Also, try to adjust the "sappiness" of your comments to a level that you know your girlfriend is comfortable with. Finally, choose especially poignant opportunities to make these types of comments - no matter how good you are with words, you can cheapen your thoughts by repeating them incessantly. For example, if you know your girlfriend is comfortable with a little sappiness in your expressions of verbal affection, rather than saying, "Hey, nice dress", you might say, "I like your dress. It reminds me of that dress you wore when we first met." This is much sweeter and has the added benefit of showing that you remember a small deal from early in your relationship.
