Problem: Article: Stick your arms up in to a V position. Your arms should be a little more forward. Your elbows should be locked and your wrists should align with your arms. Your hands should be in fists. You should see your fists from the corner of your eyes. This is the same as high v, except your arms should be down and not up. Again, make sure that your wrists are not broken, your hands are in fists, and your elbows are locked. Your thumb should go OVER the rest of your fingers in all motions. The pointer finger should face the audience. Stick your arms by your chest. Tuck your elbows and arms in but not so they are touching each other. Your hands will be in fists and your pinkies should be facing out. From dagger position, bring your arms straight up. Your pinkies should be facing out in fists, your elbows should be locked instead of bent, and your ears should feel your arms a little bit. That's how much in your arms should be in. Make sure that your wrists are not broken.. Bring your arms straight out so your body looks a little bit like a T. Bring your arms in so you can see them out of the corner of your eye. Your hands should be in fists with no fingers out. From a T position, bring your forearms in by your chest so your forearms are a horizontal position. Your pinkies should be facing out and your hands in fists.

INPUT ARTICLE: Article: 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)=500q−150q2{\displaystyle R(q)=500q-{\frac {1}{50}}q^{2}}. The first derivative, therefore, is: R′(q)=500−250q{\displaystyle R^{\prime }(q)=500-{\frac {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)=500−250q{\displaystyle R^{\prime }(q)=500-{\frac {2}{50}}q} 0=500−250q{\displaystyle 0=500-{\frac {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=500−250q{\displaystyle 0=500-{\frac {2}{50}}q} 250q=500{\displaystyle {\frac {2}{50}}q=500} 150q=250{\displaystyle {\frac {1}{50}}q=250} q=50∗250{\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=500−150q{\displaystyle p=500-{\frac {1}{50}}q} p=500−15012,500{\displaystyle p=500-{\frac {1}{50}}12,500} p=500−250{\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=p∗q{\displaystyle R=p*q}. The maximum revenue for this example, therefore, is:  R=p∗q{\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.

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.

In one sentence, describe what the following article is about: In some instances, a parent may threaten suicide as a way of frightening you or getting you to do something they want. While such threats should still be taken seriously, you also have to take measures to protect yourself emotionally. You can identify emotional manipulation suicide threats by their tell-tale "If, then" form, although sometimes they may be more subtle. Your parent may make a conditional statement, such as:  "If you leave me here all alone, I will kill myself." "If I can't come live with you, I may as well just die." "If you really love me and want me to stay alive, you wouldn't treat me like this." Convey to your parent that you are sorry they are in pain and that you want to help, but you will not be controlled or manipulated by threats. Do this in a gentle and non-assuming way, and actually follow up on your words and call for professional assistance. For example, say "Mom, I love you so much and I definitely don't want you to hurt yourself, but you can't come to live with me right now. I will do what I can to make sure you get the help you need." Such a statement shows compassion, but sets boundaries of what you will and won't do. No matter what your parent threatens, avoid trying to prove yourself or give in to the manipulation. Doing so will only jump start a repetitive cycle of your parent tossing around threats whenever things are not going his way.  Stand firm in your boundaries. And, remember, even if you were to give in this one time, it wouldn't resolve the underlying emotional problem that prompted them to threaten suicide in the first place. Let your parent know that you are concerned for his safety, thus when they threaten suicide you will take them seriously and call the emergency services so they can receive the proper treatment. Setting this boundary releases you from manipulation while ensuring your parent remains safe. Try your best to prevent any fighting or confrontations. There is no need to tell your parent that you know they are manipulating you. This may only worsen the situation and deter you from reaching a solution. A power struggle may result in your parent attempting a suicide simply to show you he or she was serious. Once you identify emotional manipulation hiding behind these suicidal threats, consult with a therapist for your parent and yourself. With the guidance of a professional, you may be able to express your feelings about being manipulated in a safe environment without fearing your parent will attempt suicide. Remember, no matter how much you love, care for, or pray for your parent, you cannot keep them alive — only your parent can do that. It is unfair for your parent to place such a burden (i.e. whether they live or die) in your hands. Clearly state your concerns, but continue to stand behind your boundaries: "Dad, it hurts me to hear you say you want to kill yourself. But, no matter what I say or do, that decision lies with you. I can't stop you from harming yourself, but I do want you to get the appropriate help."
Summary:
Learn to spot emotional manipulation. Express concern, but set boundaries. Don't give in to demands. Refrain from confronting your parent. Place the responsibility in your parent's hands.
