Distance Between 2 Points

Distance Between 2 Points Distance between 2 points can be found by using distance formula. The distance is the amount of space between points, lines etc. In mathematics the distance formula is an expression used to determine the distance between two points in a plane. The distance between two points with coordinates (x1, y1) and (x2, y2) can be represented by a formula Distance = ((x2- x1) ^2 + (y2 y1) ^2) The distance formula is obtained from Pythagorean Theorem. The below two examples illustrate how to find out distance between two points. Problem 1: Calculate the distance between the two points P (2, 1) and Q (3, 2). Solution: According to the question the coordinates of two points are P (2, 1) and Q (-3, 2). = To find out distance between P and Q use distance formula = Distance = ((x2- x1) ^2 + (y2 y1) ^2) = ((-3- 2) ^2 + (2 1) ^2) = ((-5) ^2 + (1) ^2) = Distance = 26 = The distance between PQ = Distance = 26 Problem 2: The distance between the points A (-2, -3) and B (-3, x) is equal to 5. Find value of x. Solution: Given the distance between two points is 5 = Since the distance is known we can use distance formula to set up an equation = Distance = ((x2- x1) ^2 + (y2 y1) ^2) = 5 = ((-3 (-2)) ^2 + (x (-3)) ^2) = 5 = ((-1) ^2 + (x + 3) ^2) = 5^2 = 1 + (x + 3) ^2 = (x + 3) ^2 = 24 = We get 2 solutions for x = -3 2 sqrt (6) and -3+ 2 sqrt (6).

5 Most Difficult Italian Grammar Rules Made Simple

5 Most Difficult Italian Grammar Rules Made Simple Suzy S. Are you ready for a lesson in Italian grammar?  Below, Italian teacher Liz T. breaks down the five most difficult Italian grammar rules Learning Italian can be difficult, not to mention overwhelming for new students. Many students are afraid of tackling Italian grammar, as it can be complex and confusing at first. If you take the time to learn Italian grammar, however, youre much more likely to understand what youre  actually saying, hearing, reading, and writing. Below, we break down the  five most difficult Italian grammar rules  to make it easier for you to understand. 1. Nouns and Adjectives We categorize nouns and adjectives  as either masculine and feminine. Typically, nouns  ending in -o are masculine, while nouns ending in -a are feminine. See examples below. Feminine: Donna (woman) Masculine: Uomo (man) If the noun ends in -i that means it’s masculine, but plural and  nouns ending in -e are  feminine, but plural. See examples below. Masculine: Bambini (children) Feminine: Ragazze (girls) 2. Singular vs. Plural Knowing how to create singular and plural nouns can be difficult. While there are a few  tricks to remembering the rules, its really all about memorizing the endings. See examples below. Nouns ending in  singular -o switch to plural -i Amico is changed to Amici (Friend, Friends) Nouns ending in singular -a switch to plural -e Torta is changed to Torte (Cake, Cakes) Nouns ending in singular -ca switch to -che Mucca is changed to Mucche (Cow, Cows) Nouns ending in singular -e switch to -i Professore is changed to Professori (Professor, Professors) 3. Introducing “The” Definite Articles (Singular) Singular: There are two main forms of the definite article in the singular, il (masculine) and la  (feminine)  and two alternate forms.  l’  for any noun starting with a vowel, and lo,  for any masculine noun starting with s- plus a consonant, p-s, or -z. See examples below: Masculine singular Example: Il gatto (the cat) Feminine singular  Example: La gatta (the cat) Masculine noun starting with a vowel Example: L’uomo (the man) Feminine noun starting with a vowel Example: L’amica (the friend) Masculine noun starting with a -s plus a consonant Example: Lo Zio (the uncle) Plural: Le is used to describe plural feminine “Le Ragazze” replaces La or L’. I is used to describe plural masculine “I Ragazzi” replaces il. Gli is used to describe plural masculine “Gli Zii” replaces Lo or L’. 4. Indefinite Articles “A, An” Describing Nouns Masculine nouns use “Un” before a vowel or consonant. Example: Un libro (a book) Masculine nouns use “Uno” before consonant beginning with -s, -z, -gn, -ps etc. Example: Uno specchio (a mirror) Feminine nouns use “Una” before consonant. Example: Una donna (a woman) Feminine nouns use “Un” before vowel Example: Un’attrice (a actress) 5. Italian Pronouns to Use When Describing People According to Italian grammar, there are singular pronouns and plural pronouns. Below is  a table that will help you better memorize the singular and plural pronouns: To gain a better understanding of the Italian language, it’s important to master these five grammar rules. Use flash cards, write them down, put them in a song, use visuals, anything that will help you memorize them.

On Superprof, there are three main types of language tutorials available: face-to-face tutorials, online tutorials, and group tutorials.Group tutorials are closer to traditional lessons at school with multiple students and a single teacher. If you and your family or friends are planning a trip to China, you could all get Chinese lessons together from a tutor before you go.Face-to-face tutorials are bespoke lessons with one tutor and one student. As the only student in the class, this is the most cost-effective type of private tutorial. Your tutor can spend all their time focusing on you!Finally, online tutorials are similar with the main difference being that the private tutor isn't there with you in the room. Thanks to the internet and programmes such as Skype, you can learn Chinese from anywhere with a decent internet connection and from tutors from anywhere in the world.

The Most Famous Chemists Ten People who Changed Chemistry and the Way we Live

The Most Famous Chemists Ten People who Changed Chemistry and the Way we Live We Owe a lot to These Incredible Chemists ChaptersThe Founders of Modern Chemistry: Famous Chemists from the Eighteenth CenturyPerhaps the most Famous Chemist of all: Dmitri MendeleevRenowned Chemical Scientists: the Nineteenth CenturyTwentieth-Century Chemists You Should KnowOver the last two thousand years, we’ve come a long way in science. We no longer think that everything is made of water or fire, for example, or that the human body is composed of only four things. From this subject â€" one you might sigh about in the classroom, or get frustrated at before exams â€" came some of the most important developments of the human race.The field of chemistry has contributed to this development, and this discipline has given us some of our basic knowledge of the world. All these things we might now take for granted: that the world is made of tiny little particles, that you can burn things like coal to get heat. Not only that, but chemistry has revolutionised the way we live our lives â€" offering us technologies from radiation to solar panels to the dye in jeans. If a lot of people think that chemistry is for the academic, the professor, or the weirdo scientist in his big round glasses and white lab coat, it is important to remember that it is so much more than that. And those weirdo chemists changed your life in more ways than you probably realise.In this article, we’ll look at ten of the most important scientists in the history of chemistry. You can decide just how crucial their discoveries have been.chemistry tutor guide your learning!Alfred NobelYou know this name too. This chemist and businessman, Alfred Nobel (1833-1896), is known in all fields, due to the Nobel Prize â€" the award for excellence in literature, the sciences, and economics.But this man’s biography is not as nice as you might expect. His professional life was in selling weapons â€" explosives, mainly â€" and to chemistry, his contributions were generally in inventing the explosives that he sold.Nobel’s main achievement was the invention of dynamite. Intended as a tool for construction â€" for roads, industry, and canals â€" this chemical discovery was to have a sordid history, as we know.In his later years, as the story goes, he felt a little guilty about producing one of the most destructive chemical substances ever devised. He donated his massive fortune to inaugurating the Nobel Prize in Chemistry, Physics, Medicine, and Peace.Find out what the essential equipment you need in your chemistry set is.Twentieth-Century Chemists You Should KnowIn the twentieth century, the subject of chemistry blossoms even further, branching out into different sub-disciplines and becoming the subject we know today.Linus PaulingLinus Carl Pauling (1901-1994) has often been hailed as one of the most important scientists ever to have lived â€" and if you haven’t heard of him, now is your opportunity.Pauling essentially invented, single-handedly, what we now know as molecular biology â€" the study of things like proteins and acids in the body â€" and quantum chemistry, or the study of the relationships between the smallest things in the atom. And if, at school, you’ve heard of covalent or ionic bonds â€" you have Pauling to thank for understanding them too. Learn more about chemical bonds in our piece on basic chemistry concepts.As a lifelong activist for nuclear disarmament, Pauling was not only a Nobel Laureate in chemistry, but he won the Nobel Peace Prize too. Finally, his research into proteins also inspired the work of Francis Crick and James Watson, who, without Pauling, would never have discovered the structure of DNA.Dorothy HodgkinNow time for a chemist that is often overlooked in the histories of famous scientists: Dorothy Hodgkin (1910-1994). Another Nobel Laureate, Hodgkin is the only British woman to have ever won a Nobel Prize in a science. Hodgkin’s main discoveries were in the structure of molecules and proteins in the body, and her research had a massive impact on biochemistry and medicine. She and her team worked on the structure of penicillin, vitamin B12, and, importantly, insulin. Her career was notable for her advocating for the importance of knowledge of insulin, too â€" for its central role in diabetes.My online chemistry tutor introduced me to her work; she is a truly admirable scientist!Kathleen LonsdaleAnd another twentieth-century chemist that deserves to be more famous than she is: Kathleen Lonsdale (1903-1971). As a scientist, she was one of the first women to be elected as a Fellow of the Royal Society and was awarded numerous titles for her important work in crystallography, or the study of the arrangement of atoms in crystals.Alongside her work on diamonds, and her profoundly influential research into the structure of benzene, she was an advocate for pacifism and an inspiration for women scientists across the world.Still hungry for chemistry?

Prepare For May 2015 AP Exams - Redesign Physics Exam

Prepare For May 2015 AP Exams - Redesign Physics Exam Now that its March, AP exams are only two months away (find the complete AP exam schedule at the College Boards website).  If youre currently enrolled in an AP class, taking the AP exam in May is a great way to get college credit.  However, many colleges have upped their requirements for awarding credit for AP courses, with some of the most prestigious colleges only giving credit for 5s the top score on the AP exam.If youre thinking you could use a little assistance preparing for your AP exams, AJ Tutoring is here to help!  We offer a couple options for AP exam prep in 2015: group classes and one-on-one tutoring.AP Test Prep Group ClassesAJ Tutoring offers group classes at our Palo Alto office for AP US History and AP English Language.  Both the APUSH and the AP English Language prep classes are taught by our resident experts in the subjects, Dominic Booth and Emily Foster.  Our group classes include 6-8 hours of classroom instruction as well as two full-length proctored pract ice AP exams.For course schedules  or to sign up for a class, please visit our AP exam prep page.One-on-One AP Exam TutoringAJ Tutoring also offers private one-on-one tutoring for all other AP subjects.  Each student meets with their tutor for 3 to 5 weekly sessions leading up the AP exam in early May.  During the sessions, the tutor focuses on timing and test-taking strategies appropriate for problem solving, essay writing, and multiple choice questions on the exam.  The tutor will also review the students weaker content areas and potentially assign additional content review for homework (i.e. outlining important material or creating timelines).  Generally, homework consists of full-length AP exams or 90-minute assignments relating to test-taking strategies or content review.One-on-one AP tutoring students are also encouraged to take proctored AP practice tests at our Palo Alto office.Changes to the AP US History and AP Physics Curriculum in 2014-15If your student is currently enrolled in AP US History or AP Physics 1 or 2 (the replacement for AP Physics B), you may have heard that the AP curriculum for both courses changed significantly this year.The AP US History course has been redesigned to focus on broader historical understandings.  The College Board highlighted seven major themes: ideas, beliefs, and culture; America in the world; environment and geography; politics and power; identity; peopling and migration; and work, exchange, and technology.  While students are still expected to have extensive content knowledge of American history, the course now focuses on fitting content knowledge into these major historical themes and finding causal connections between events.  The AP US History exam has also been redesigned for 2015, with an increased multiple choice focus on interpreting sources, and new short answer questions.AP Physics has also changed extensively, with the one-year AP Physics B course now split into a two-year sequence of AP Physics 1 and 2.  AP Physics 1 covers Newtonian mechanics; work, energy, and power; and mechanical waves and sound.  AP Physics 2 includes fluid mechanics, thermodynamics, electricity and magnetism, optics, and atomic and nuclear physics.  The AP Physics exams have been revamped accordingly, with more emphasis on deep conceptual understanding of physics and less emphasis on rote mathematical operations.AJ Tutorings AP US History and AP Physics tutors are fully versed in the redesigned curriculum and AP exams, and weve created extensive proprietary material to assist students who are preparing for the first administration of these redesigned tests in 2015.  If you have any questions about the AP changes or would like to sign up for tutoring, please give us a call at (650) 331-3251 or email us at info@ajtutoring.com.  Were looking forward to working with you!

Tutorfairs Foundation On-Demand Review

Tutorfair's Foundation On-Demand Review As one of the Founders of Tutorfair, my mission has been to make tutoring fair for all.      Last  week the Foundation signed off the final report of our pilot study for Tutorfair On-Demand with Nesta, so I thought it would be a good time to reflect on the  learning we’ve seen from this pilot. Why did we start On-Demand? We created On-Demand for Nesta, the innovation foundation. They had noticed in 2016 that volunteering projects were making a real difference in education but were not reaching large  areas of the country.  We took up the challenge because we thought the solution might also fix an issue for the Tutorfair Foundation.   We had lots of tutors trying to volunteer  who we were unable to place  most in our projects with schools.  The On-Demand app would let  volunteers anywhere in the country answer questions whenever they wanted. What have we found? Fast forward to 2019 and we now have a real live service that works. Pupils from schools who sign-up can access a tutor for GCSE maths instantly on their phones.  They feel happy with the help they get and their teacher can see what they struggled with. Volunteers can help when and where they are able to, without needing to make complex commitments. The Foundation team can train the volunteers online and monitor for quality and safeguarding.   Now that hundreds of students and volunteers and 30 schools have used it we have loads of great feedback on how to make it all better. What’s most exciting is that we’re starting to find from our small sample of students in the pilot that students who used the app more frequently saw some grade improvement.   One of the most important things moving forward to more schools and more students will be proving this result to be statistically significant. What next? As we wrap up the pilot study we are really excited with the potential for On Demand.  We feel confident that it will  be shown make a real difference to grades when we can do a full proof of concept.   This would mean for our volunteers that they are making a measurable contribution to addressing educational inequality.  When we can prove that we make an impact, there is so much potential to extend to new students and subjects and for this to be a whole new way for teachers and tutors to work together. With thanks to... Before signing off I must thank Nesta and DCMS for setting a visionary challenge and supporting us on the way. Pete and Tas on the Foundation team have designed and run everything. Curvestone help us with development. 364 tutors volunteered to help. And thanks to everyone else in the Tutorfair extended family who has helped to make this idea into a reality.

Catch Em All (With Safety And Intelligence)

Catch 'Em All (With Safety And Intelligence) youtube.com But, some people are throwing caution to the wind entirely and doing anything to catch all of the Pokémon they possibly can. Catching  Pokémon and getting hurt in the end is not worth the hassle. Here are some tips to indeed catch em all, but with safety and intelligence. 1. DO NOT CATCH POKÉMON AND DRIVE. This is just like texting and driving: You cannot do both at the same time and be safe. There is no reason that you can’t wait until you arrive at your destination to catch more Pokémon on your app. Virtual non-existent little monsters in an app are not worth a car wreck or the financial mess that would follow a car wreck. It doesn’t matter if you’re not texting. Looking at your phone, in general, is a driving distraction. According to www.cdc.gov:  â€œEach day in the United States, more than nine people are killed and more than 1,153 people are injured in crashes that are reported to involve a distracted driver. Distracted driving is driving while doing another activity that takes your attention away from driving.” Catch Pokémon with this app at your leisure, but do not endanger yourself or others because of a game. facebook.com 2. WATCH YOUR DATA. It is very easy to download an app onto your phone, not really caring about the data usage and just playing whenever you feel like it. Who needs WiFi, right? Well, you might. Sure, there are plenty of people out there who pay their own phone bills and might even have a WiFi hot-spot on their phone. But, those who belong to a shared data plan with family members or do not have much of a data plan at all need to be aware of data consumption. Going into settings and then apps on iOS devices allows users to turn off an app’s ability to use cellular data. On Android devices, you can set your phone to stay within your data limit and prevent further worries. 9to5mac.com asus.com Some cell phone companies may offer unlimited data but not all of them do. Make sure you are being smart about data consumption and if you do go over your limit, be prepared to pay for it â€"literally. 3. OBEY PHONE RULES/REGULATIONS. Whether you are at your job or on campus, obey the phone regulations already set into place. For example, if you are in the middle of a lecture, do not whip your phone out checking for Pokémon and then proceed to ignore the lecture due to being obsessed with catching the Pokémon should any be present. Moreover, do not almost lose your job over the app. Reddit user scarstruck4 explained that having used the app at work almost cost him his job. Scarstruck4 wrote that he works, “in a Banking/IT company,” and, “Employees of my company are allowed to use smartphones inside the premises [but] using camera is strictly prohibited as we have access to clients personal data.” When he began using the app in order to catch a Pokémon  for it, a higher-up accused him of “clicking photographs,” and his “iPhone [was] confiscated.” While the Reddit user did not lose his job, he was still put through the hassle of having his phone checked for anything incriminating and let off with a warning. That should be enough to take to heart this phrase from Professor Oak himself: “Theres a time and place for everything, but not now.” http://e.lvme.me/mdus4ch.jpg 4. DO NOT TRESPASS. http://cdn.smosh.com As much as the joke keeps being made that the legendary Pokémon MewTwo could be at Area 51, by no means should you travel into restricted areas. That is not only putting your safety in jeopardy, but you could face legal issues for trespassing. The hassle of a lawsuit is not something anyone with a job or college career and opportunity for work in the future should have to deal with. Have fun but do not be outright stupid and enter dangerous or restricted areas that you should be nowhere near. Go ahead and catch ‘em all but with safety and intelligence.
