Q: If you talk to your parents, you may be able to come up with a compromise for your dating life. Plus, having a calm discussion with them could help them see that you're mature and perhaps start thinking that maybe you are ready to date. Try saying something like, "Mom, I know you said I'm not allowed to date yet, and I respect that. I wanted to know if we could talk about why you feel that way." Ask your parents what would make them more comfortable with you dating and see if there is a way you can cater to that. For example, maybe you could agree to check in with them every hour that you're away or agree to an early curfew. Breaking your parent's trust is a really big deal and something that takes a very long time to recover from. Having to keep up with different lies will put a strain on your relationship and affect how close you are to your parents. Are you willing to risk the potential aftermath if they find out you've been lying to them? This could mean even stricter rules, a loss of privileges, and a strained atmosphere at home. It's hard to have a solid relationship if it is built on secrets. Talk to them beforehand about why you need to keep things private and make sure they're okay with the arrangement. Secrets can sometimes be fun, but they can also sometimes lead to people feeling shame or regret over their actions. If the person isn't okay with hiding things from your parents, you need to respect that and not pressure them. Think about how you would feel if someone pushed you to participate in something that made you feel uneasy. Lying and living a secret life can be damaging to your sense of self, and it also can be a big stress that negatively affects your health. If you're going to date behind your parents back, think about it carefully beforehand and decide if you're okay with your choice. Keep in mind that you can always stop if you decide that secret dating isn't the right choice for you.
A: Have a conversation with your parents to understand their concerns. Consider how this could affect your relationship with your parents. Think about how your date will feel about abiding by your secrecy rules. Question whether dating is worth the stress of keeping a big secret.

Article: Learning a foreign language well takes time - there's no way around it. Long, infrequent cram sessions just won't work. Instead, study or quiz yourself in short bursts of 5-10 minutes. Try to do several of these throughout the day. Once you build up a good knowledge of the language, you will retain more from longer sessions. While they seem like the bane of any language student's existence, flashcards are actually a proven way to learn vocabulary. They're also cheap and easy to make. You can keep a stack of flashcards on you and quiz yourself whenever you have a few spare minutes throughout the day. Just focus on a few words at a time. You can use index cards for a traditional choice, or websites or apps to create virtual cards. The key to flashcards is repetition--use them often, and quiz yourself on old flashcards, too. Use the words as often as you can to help them stick. Studies show that learners need to encounter words several times in different contexts before they really stick. To speed this process up, whenever you learn a new word, look at how it is used in context, and then follow a series of steps: Pronounce the word and spell it Study the meaning of the word (look it up if you don't know it) Create a sentence in your own words using the word Write the new word and its meaning several times The same holds true for learning a new phrase. Say it outloud, check their meaning if you aren't sure, and make up new sentences that use the phrase. To retain vocabulary, keep using these words and phrases, even after a test or after moving on to new topics. Practicing your foreign language with native speaker or someone who knows it well supercharges your learning. Not only will you have the chance to put your knowledge into action and build confidence in speaking, you'll also learn new vocabulary from you partner. All while having fun! You can find a friend, tutor, or teacher who you can practice with. Check with a language instructor, look online for language groups in your area, or look for someone to practice with online via language learning sites. You can also try a tandem partnership with someone who is trying to learn your language. Spend part of the time practicing the language that is foreign to you, then switch to your own language and help your partner learn.
Question: What is a summary of what this article is about?
Study in frequent short bursts. Trust flashcards. Work with new words, don't just look at them. Read, write, and repeat phrases to cement them in your brain. Make friends with a conversation partner.

Q: To get an object's instantaneous velocity, first we have to have an equation that tells us its position (in terms of displacement) at a certain point in time. This means the equation must have the variable s on one side by itself and t on the other (but not necessarily by itself), like this:s = -1.5t2 + 10t + 4 In this equation, the variables are: Displacement = s . The distance the object has traveled from its starting position. For example, if an object goes 10 meters forward and 7 meters backward, its total displacement is 10 - 7 = 3 meters (not 10 + 7 = 17 meters). Time = t . Self explanatory. Typically measured in seconds. The derivative of an equation is just a different equation that tells you its slope at any given point in time. To find the derivative of your displacement formula, differentiate the function with this general rule for finding derivatives: If y = a*xn, Derivative = a*n*xn-1.This rule is applied to every term on the "t" side of the equation. In other words, start by going through the "t" side of your equation from left to right. Every time you reach a "t", subtract 1 from the exponent and multiply the entire term by the original exponent. Any constant terms (terms which don't contain "t") will disappear because they be multiplied by 0. This process isn't actually as hard as it sounds let's derive the equation in the step above as an example:s = -1.5t2 + 10t + 4(2)-1.5t(2-1) + (1)10t1 - 1 + (0)4t0-3t1 + 10t0-3t + 10 " To show that our new equation is a derivative of the first one, we replace "s" with the notation "ds/dt". Technically, this notation means "the derivative of s with respect to t." A simpler way to think of this is just that ds/dt is just the slope of any given point in the first equation. For example, to find the slope of the line made by s = -1.5t2 + 10t + 4 at t = 5, we would just plug "5" into t in its derivative. In our running example, our finished equation should now look like this:ds/dt = -3t + 10 Now that you have your derivative equation, finding the instantaneous velocity at any point in time is easy. All you need to do is pick a value for t and plug it into your derivative equation. For example, if we want to find the instantaneous velocity at t = 5, we would just substitute "5" for t in the derivative ds/dt = -3 + 10. Then, we'd just solve the equation like this:ds/dt = -3t + 10ds/dt = -3(5) + 10ds/dt = -15 + 10 = -5 meters/second Note that we use the label "meters/second" above. Since we're dealing with displacement in terms of meters and time in terms of seconds and velocity in general is just displacement over time, this label is appropriate.
A:
Start with an equation for velocity in terms of displacement. Take the equation's derivative. Replace "s" with "ds/dt. Plug in a t value for your new equation to find instantaneous velocity.
