Online Algebra 1 Practice Tutors - Algebra 1 Tutors

Online Algebra 1 Practice Tutors - Algebra 1 Tutors H.C.F. (Highest common factor) and L.C.M. (Lowest common factor) is the part of algebra 1. Methods to solve H.C.F and L.C.M.: - Division method Factorization method. Lets practice few problems of algebra 1:- Example: - Find out the L.C.M. and H.C.F. by factorization i) X^2 + x, x^3 x ii) X^3 + 2 x^2, x^3 + 3 x^2 + 2 x Solution: - i) 1st expression = x^2 + x = x ( x + 1) 2nd expression = x^3 x = x ( x^2 -1) = x (x + 1) (x 1) The common factors of the two expressions are x and (x +1). Therefore H.C.F. = x (x + 1) (x 1) is the extra factor in the 2nd expression. Hence the required L.C.M. = x (x + 1) (x 1) ii) 1st expression = x^3 + 2 x^2= x^2 (x + 2) = x * x * ( x +2) 2nd expression = x^3 + 3 x^2 + 2 x = x(x^2+3x+ 2)=x (x^2 + 2 x + x + 2) =x {x ( x + 2 ) + 1 ( x + 2 )} =x (x + 2) (x + 1) In both the expressions, the common factors are x and x + 2 Therefor H.C.F. = x (x + 2) The extra factors are x in the 1st expression and x + 1 in the 2nd expression. Therefore L.C.M. = x ( x + 2) x (x + 1) = x^2 (x+1)(x+2)

Cytoplasm

Cytoplasm Cytoplasm: Cytoplasm can be defined as a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. Fundamentally cytoplasm is the constituent that occupies the space of the cell. It is a jelly-like constituent and it is 80% water and is generally pure and pale. It melts when it is frantic or stirred. Cytoplasm is stated as cytosol, which implies ingredient of the cell. The cell membrane surrounds the cytoplasm and it also surrounds the nucleus and the cellular organelles. Cytoplasm comprises of the cytoskeleton which provides the cell its shape. The cytoplasm is made of liquefied nutrients and it supports to dissolve discarded products. It aids the motion of the cellular constituents around the cell by a process termed as cytoplasmic streaming. Cytoplasm also contains several salts and is a good conductor of electricity. Cytoplasmic structure: Cytoplasm is the liquid where the organelles are suspended. It occupies the spaces which are not filled up by the organelles. The ingredients of cytoplasm are cytosol, organelles and cytoplasmic inclusions. Cytosol Cytosol makes up about 70%-80% of the capacity of the cell. It comprises of water, salts and organic fragments. Cytosol is made of a combination of cytoskeleton fibers, organic and inorganic compounds that are mixed in water. It also possesses protein filaments that constituents the cytoskeleton, soluble proteins and structures like ribosomes, proteasomes. The inner, more liquefied and granular region of the cytoplasm is referred as the endoplasm. The web of fibers and high absorptions of the dissolved macromolecules like proteins is responsible for macromolecular assembling. Organelles Organelles are membrane bound cellular structures which are present in the cytoplasm. They reside inside the cell and accomplish specific functions that are essential for the existence of the cell. Some of the components of the cell that are present in the cytosol are organelles like mitochondria, endoplasmic reticulum, Golgi apparatus, vacuoles, lysosomes and chloroplasts. img alt=Organelles data-cke-saved-src=https://images.tutorpace.com/biology/cytoplasm_3.jpg src=https://images.tutorpace.com/biology/cytoplasm_3.jpg 534px;= height:= 382px;= Cytoplasmic Inclusions The cytoplasmic inclusions are minute particles present in the cytosol. A massive range of inclusion bodies are present in different types of cell types. The different inclusions present are calcium oxalate crystals or silicon dioxide crystals of plants in order to store granule like starch, glycogen, etc. Lipid droplets are also example of inclusion bodies, which are spherical droplets, made of lipids and protein particles and are present in both prokaryotic and eukaryotic organisms as an intermediate to stock lipids like fatty acids and sterols. These drops occupy the volume of adipocytes which are specific storage cells, and are also found in other cell types. Functions of cytoplasm: Cytoplasm is the site where many biochemical reactions are carried out which are essential for maintaining life. The cytoplasm is the site where the cell extends and expands as it grows. The cytoplasm acts as a medium for the suspension of organelles. The cytoskeleton present in the cytoplasm gives shape to the cell and it also aids movement. It also facilitates the movement of the different cellular contents The enzymes present in the cytoplasm digest the macromolecules into much small parts for their proper digestion and availability for the other cellular organelles like mitochondria.

How to Prepare for an Open-Book Test

How to Prepare for an Open-Book Test The very phrase, Open Book Test, evokes immediate relief over students. It automatically de-stresses them due to its implications that studying isnt necessary and that very little preparation is needed. Unfortunately, these thoughts are a huge trap. Although it is perfectly understandable why one would think an open book test requires no studying, that is simply not the case. Here are some great tips on how to mentally prepare for test daythat you may find useful as well. Making an exam open-book certainly makes the test-taking process a lot easier, but it does not eliminate the need for studying altogether. The key to mastering these tests is mastering your notes, and there are a few steps to take for you to do that. Just having your textbook or semester-filled notebook by your side will not guarantee quick and easy answers to every test question you face. Going into this test blindly would be just as dangerous as going into regular test with such a blank mentality. The first step would be to organize your notes. If you just bring a few textbooks and notebooks with absolutely no idea where certain information is, then youll spend most of your testing time looking for answers rather than giving them. Go through your books and notes ahead of time to determine what topics they each cover and on what pages. Take some highlighters and post-its and mark sections as needed. Here are some more great study tips on how to organize your notes. More importantly, identify exactly what youll need to know for this test and then specifically mark the areas of your notes that pertain to those subjects. This way, youll only be searching through notes that you know are relevant to your test material. Being able to quickly recognize where specific topics lie in your notes is half the battle in conquering an open book test the quicker you can get to the answers, the quicker you can use them. Once youve gone through these loads of notes, narrow down the material to establish what you really need to bring with you to the exam. Bringing too much material will overwhelm and distract you, so it is best to only bring the items you definitely know youll benefit from. Open book tests can often make students forget that they can, in fact, still memorize certain facts/concepts and dont have to rely on the notes for everything. Approaching the test this way will reinforce your confidence and allow you to identify which concepts you actually do need the notes for. After youve narrowed down the study material to bring to the test, examine all of it once again. This is both to familiarize yourself with it and see how well you respond to it at a glance. The reason for this is that you dont want to show up to the test with notes that once worked for you and then realize you have no idea what those bullet points mean anymore. Perhaps its been too long since you actually scribbled those notes down or maybe you just cant make out your handwriting from that day. Either way, it is important that you determine any of these possible issues and fix them. Annotate your notes with updated summarizations of what the main points are; re-write the entire page if you have to. Do whatever it takes to make sure you are providing yourself with notes that make sense to you so you will have no trouble comprehending them. You may also want to check out this guide to the study guidethat may help you prepare as well. Overall, remember to keep the importance of test preparation in mind even when facing an open book test. The teacher is allowing you an incredibly helpful resource dont waste it by getting too comfortable! Prepare adequately and that comfort will take precedence when test-taking time arrives.

An Interview with a Volunteer Adam Schauer - Heart Math Tutoring

An Interview with a Volunteer Adam Schauer - Heart Math Tutoring An Interview with a Volunteer: Adam Schauer An Interview with a Volunteer: Adam Schauer September 3, 2019 It didn’t take long for Adam Schauer to become a devoted member of the Heart Math Tutoring volunteer team. Heart Tutoring’s ability to “immediately impact” the Charlotte community is what first intrigued Adam, a Client Portfolio Manager at Barings, about serving with us years ago. We recently sat down with Adam to hear what makes being a Heart Tutoring volunteer special, in his own words. “You don’t even think about math. You’re just interacting with them.” Beyond instilling the life skills that come with learning basic math, Adam says it’s the opportunity to mentor and positively impact children’s lives that makes the experience so rewarding. And Heart Tutoring’s playful approach to teaching math is a natural way to strengthen those mentor-mentee relationships, he reflects. Because the lesson plans are easy to grasp, and oriented around games and interactive problem-solving, children learn by way of connection. Adam his partner tutor, Mike with their student Adam says he enjoys engaging with children at their various learning levels and engaging in “friendly competitions” with his partner teacher to give the most fun or interesting lesson each week. “[My partner and I] try to make it a fun, entertaining, playful environment,” he says. “We’ll joke and ask our student whose lesson he liked more that week.” HMT Note: This also challenges the student to reflect on their previous lesson. Way to go, Adam! “30 minutes is all it takes.” Charlotte professionals like Adam tend to stay busy in and outside of work. But Adam encourages those considering Heart Tutoring to not let the time commitment dissuade them from taking that step. As Adam puts it, “volunteering just 30 minutes per week during limited times of the year can have a lasting snowball effect on the long-term development of these children.” “It’s refreshing to step out of the busy world and step into time with someone who needs more support and help than we realize,” he says. Thirty minutes a week can leave a lifetime impression, and to help maximize that positive impact, Adam started a carpool to make volunteering that much easier for his Barings colleagues. “The long-term impact is their interest in learning more.” Beyond the successful math lessons, the biggest reward for Adam is seeing Heart Tutoring kids develop a new curiosity in general learning. “Obviously you want them to have an ability to grow through academics … But the longer-term impact â€" where you can really see the kids come out of their shell â€" is their interest in learning more. They bring an excitement to their tutoring session and they take that excitement home, to other studies, to telling their friends.” Adam, his partner tutor, Mike, with their student her mom “That’s what keeps me coming back.” With the responsibility to mentor comes what he calls a “welcome challenge.” Recognizing that all children respond differently to guidance and direction, Adam strives to approach every interaction with his students uniquely. “Once you make that connection with a child, you really start building a strong relationship. And that’s what keeps me coming back the most,” he says. “It’s the laughs, the giggles, the challenges.” One testament to the great impact of these tutoring sessions, Adam says, is interacting with students long after the sessions have ended. When you see them in the halls even years later, “they run up to you, give you a high-five; they remember you and the impact you made.” Adam says it’s “the laughs, the giggles, the challenges” that sum up his favorite aspects of being a Heart Tutoring volunteer. We’re grateful for Adam and his fellow Heart Math Tutoring colleagues from Barings. They are so giving of their time and financial generosity â€" and we wouldn’t make the same impact without them!
