Average Rate Of Change

Average Rate Of Change Average rate of change is the change in the quantity of one variable divided by the change in the other variable. Any function has an output value for a given input value. To calculate the rate of change for the given values, the change in its corresponding values of the function is calculated and divided by the difference in the input values. Example 1: Find the average rate of change in the values for the function, f(x) = 3x+ 6 from 5 to 1. Given if a function f(x) = 3x + 6. Now, average rate of change is to be calculated for values from 5 to 1. So finding their corresponding function values, we get: f(5) = (3 * 5) + 6 = 15 + 6 = 21 f(1) = (3 * 1) + 6 = 3 + 6 = 9 Change in values between 5 to 1 is f(5) - f(1) = 21 - 9 =12 Average rate of change = 12/ (5-1) = 3 Example 2: Find the average rate of change in the values for the function, f(x) = 2x+ 4 from 3 to 2. Given if a function f(x) = 2x + 4. Now, average rate of change is to be calculated for values from 3 to 2. So finding their corresponding function values, we get: f(3) = (2 * 3) + 4 = 6 + 4 = 10 Then, f(2) = (2 * 2) + 4 = 4 + 4 = 8 Change in values between 3 to 2 is f(3) - f(2) = 10 - 8 = 2 Average rate of change = 2/ (3-2) = 2

3 Habits that are Hurting Your SAT Prep

3 Habits that are Hurting Your SAT Prep If youre a high school upperclassman, you know that time is precious. Between homework, sports, part-time jobs, and spending time with friends, your schedule is pretty full. For juniors and seniors that plan on taking the SAT, it can be difficult to find time to study before the test. Taking time to prepare for the SAT is essential to doing well, but its the quality, not the quantity, of studying time that can truly make a difference in your score. With that in mind, here are three habits that are hurting your SAT prep. 1. Crash studying for the SAT Dont think that just because the material on the SAT is material you may have already learned that you will be able to ace the test after only a few study sessions. Cramming a week before the SAT is like participating in a triathlon without ever training. Crash studying not only is an ineffective way to learn and remember content, but can also hurt you when it comes to test time. Learning so much information in a short period of time can leave you anxious and forgetful the last things you need to feel on test day. Having a strict study schedule that you adhere to is key to maximizing the time you spend studying. Spacing out your studying over several months will ensure that you arent cramming the week before the test. Instead of spending eight hours a night the week before the SAT trying to memorize information, spread that time out over at least three months. Plan to set aside an hour a day at the beginning of your study schedule to ease into studying, then amp up the amount of time as the test nears. Although some of the content may seem familiar, you will need to familiarize yourself with content you may not have seen in years and give your brain ample time to recall it. You may find working with aprep bookbeneficial. 2. Faking a SAT practice test Youve all heard the saying practice makes perfect, and the SAT is no exception. If you are taking SAT practice tests before the actual exam, you are on the right track in your studying course. Practice tests help you to familiarize yourself with the structure of the test questions and can provide you with valuable data regarding your strengths and weaknesses. However, if practice tests are not taken correctly, you could be wasting your time. [RELATED: How is the New SAT Scored?] When taking the practice test, it is important to choose a location that mimics the location you will be in when taking your SAT. Do not take a practice test in your living room with the TV on, laying in bed, or in a location where you know there will be distractions. Your goal is to prepare yourself for the same environment that you will be in when you take the real test. Create a good study environment, with a quiet, comfortable space and a desk. When you walk in to take the SAT, you want it to feel familiar. Simulating a practice test also means adhering to the rules that you will have to follow when taking the actual test. Do not use any tools to practice that you will not be able to use on the test. Furthermore, do not break up the test into sections over days or take longer breaks than you will be allowed on test day. Training your brain to focus throughout the whole test is vital to succeeding on the SAT. 3. Focusing on the what and not the why Getting the correct answer is of course the goal when taking the SAT. However, when studying for the test, the answer isnt the only thing that matters. After a practice test, it is important to look back at your incorrect answers and figure out why your answer was wrong, and why the correct answer was right. Each practice test and problem should be a learning experience, whether you originally got the answer right or wrong. The questions you see on practice tests will not be duplicated verbatim on the actual test, so memorizing an answer will only waste your time. Instead, focus on the type of mistake you made, and find out how to avoid making that type of mistake in the future. Similar questions will likely stump you on the actual test if they fooled you on the practice test, so focus on where your line of thinking went wrong. Ensuring that the time you spend studying for the SAT is spent in the correct way will determine your success come test day. Improper studying techniques can waste time and set back your studying schedule ultimately hurting your score on test day. Avoid these habits that are hurting your SAT prep, and you can maximize the quality of your studying.

3 Important Tips When Translating French to English

3 Important Tips When Translating French to English Megan L. Translating French to English is a common way to study the language and improve your skills. Tutor  Nadia B.  shares three big tips so you dont get lost in translation Are you learning French and need to translate some of your French homework into English? Or perhaps you want to translate a  French text just to be sure that you have understood the meaning? Translation is a useful tool for improving comprehension and fluency, so read on for three important tips for translating French to English. These tips will ensure you translate  quickly and accurately  on your first try! 1. Dont translate idiomatic expressions literally. There are many French expressions that shouldnt be taken  literally when translating French to English. The literal translation wont reflect the meaning of the expression. If you come across an expression that, when translated literally makes no sense in context, youve probably found an idiomatic expression. Here are some examples of French idiomatic expressions and how they can be translated into English: une bouche dincendie fire hydrant (Since  bouche means mouth in English, a mouth of fire isnt a correct translation!) une bonne fourchette a hearty eater (or, literally, a good fork, but that lacks meaning to English speakers!) faire le pont to make a long weekend (literally, to make a bridge, but it refers to the French habit of taking a four-day break by adding Friday or Monday to the weekend plus the mid-week day that a holiday falls on) To improve your skills when translating French to English, try to learn as many idiomatic expressions as possible. If youre listening to a French speaker and you dont understand an expression they use, inquire as to the meaning so you can continue to build your knowledge base. Over time, this will make French translation easier and more rapid as you draw on the knowledge you already possess. 2. Use online forums and dictionaries to get help when needed. When translating French to English, sometimes you can get stuck with certain expressions or usages. If you just cant figure out how to appropriately translate something, forums like WordReference  offer valuable help from native French speakers and highly knowledgeable second-language French speakers. There is a huge archive of threads covering a wide range of topics in French, so you can type in a phrase or word to learn more details about it. After all, when possible it is always in your best interest to use human translation for the most accurate understanding. Online French dictionaries are another excellent resource. A well-respected one is Larousse. Here,  you can access a French-English dictionary, as well as a French monolingual dictionary, in which you can find words and definitions all in French. The monolingual dictionary can be an especially great way to increase your knowledge and your proficiency in French as you research your translation query. 3. Use cognates, but watch out for false cognates. Cognates are a great help when trying to increase fluency in a language and translate quickly. Here is a short list of French-English cognates: immense immense amusant amusing, fun la page the page la musique the music la tomate the tomato le candidat the candidate lhôpital the hospital The only thing to remember with cognates is that there can also be faux amis  (false cognates). These tricky  French  words sound like a word in English but are not equal in meaning. Here are some French false cognates to watch out for: actuellement currently (not actually) attendre to wait (not to attend) assister to attend (not to assist) bras arms (not bra) blessé injured (not blessed) une librarie bookshop (not library) un raisin grape (not raisin) If you follow these three tips, you should be translating with confidence in no time! The more attention you pay to the details and work on increasing your vocabulary and knowledge of idiomatic expressions, the more you will find that your translations are accurate and thorough.

Multiplying mixed numbers

Multiplying mixed numbers Different arithmetic operations such as multiplication can be used to solve fractions. Fractions are numbers which have numerator and the denominator of the p/q form. The denominator is not equal to zero. There are different types of fraction such as proper, improper and mixed fraction. The mixed number is a combination of a whole number and proper fraction. The fraction which has numerator greater than the denominator is the improper fraction. A mixed number can be changed into improper fraction and vice versa. Example 1: What is the answer when the mixed fractions 2 x 1 are multiplied? Solution: Given are two mixed fractions 2 and 1 . Change the mixed number into improper fractions: This gives 2 = (2 x 4 + 3)/4 = (8 + 3)/4 = 11/4. Then, 1 = (1 x 4 + 1)/4 = (4 + 1)/4 = 5/4. Multiplying the fractions gives 11/4 x 5/4 = 55/16. Converting 55/16 to a mixed fraction gives 3 7/16. Hence, the answer is 3 7/16. Question: Multiple choice question (Pick the correct option.) What is answer for multiplying 6/5 x 2 ? a) 1 b) 3 c) 2/3 d) None of these. Correct answer: option b. Given are two fractions 6/5 and 2 . Change the mixed fraction into improper fractions: This gives 2 = (2 x 2 + 1)/2 = (4 + 1)/2 = 5/2. Multiplying the fractions gives 6/5 x 5/2 = 6/2 = 3. Hence, the answer is 3.

How to Balance Work and Grad School

How to Balance Work and Grad School Congratulations on your decision to attend grad school! According to the Census Bureau, just 9.3% of American adults over 25 have earned a masters degree. Pursuing a masters degree is no easy task, but it is an endeavor that can yield a number of benefits. Grad school allows you to explore your academic passions on a deeper level, participate in cutting-edge research projects, make valuable contacts in your field, and strengthen your employment prospects. Some graduate students choose to work and study at the same time, while others do so out of necessity. In any case, a proper balance between both responsibilities is indispensable and can be achieved through the following advice. Heres how to balance work and grad school: Balance work and grad school by communicating with your supervisor To balance the demands of academia and work simultaneously, you must first and foremost learn how to manage your time. Grad school is quite different from your undergraduate years, so although you may have held a job while you worked toward your bachelors degree, your experience juggling both this time may present unexpected challenges. As you work toward your masters degree, your work schedule should remain fairly predictable. You should have a clear idea each week of which days and times you will have off; this way, you know exactly when and for how long you will be able to work on class assignments. Your boss should absolutely be aware of your plans to attend grad school, so talk to them as soon as possible to avoid scheduling disasters. If it is impossible for you to have a consistent schedule given the nature of your job, you should at least aim to keep your number of work hours steady. Open communication with supervisors is key to maintaining a healthy balance between work and school. [RELATED: What I Wish I Knew Before Starting Business School] Balance work and grad school by taking your study materials to work Work and grad school are two enormous responsibilities on their own. When you also consider all the other chores and errands you must tend to in a week, you may find yourself feeling overwhelmed. It is for this reason that you must make the most of your downtime at work. During breaks, for instance, may be a great time to get ahead on class readings, studying, and other assignments. Take portable study materials to work, such as lightweight textbooks and flash cards, that you can easily look at in your free time. Since using your cell phone may be frowned on at work, it may be best to bring printouts, rather than electronic copies, of texts. [RELATED: How Students Can Improve Their Research Skills] Balance work and grad school by making some social sacrifices To maintain your job and your grad school average, you may need to make some social sacrifices. This implies that you might have to decline invitations to friendly gatherings at times. If it is Friday evening and you have a big project due on Monday, it may be wise to stay at home and work on your project rather than go out with your friends. You should not, however, give up your social life completely because of a demanding schedule. Seeing friends and interacting with others is not only enjoyable, it is essential to our emotional well-being. So, stay in contact with those you care about. Just make sure social outings do not interfere with work or study time.
