Then the system asks you to select the part to be analyze and destination folder. The tool then re...
In this video, the instructor shows how to identify the percentage change using proportions. When a given quantity increases or decreases by certain amount then we can calculate the percentage change in the quantity, which can be either increase or decrease based on the new value of the quantity. To solve these kind of situations you should know that the ratio of amount of increase (or decrease) of an amount to its original amount is equal to the ratio of percentage increase (or decrease) to ...
In this video the instructor shows who to simplify radicals. If you have a term inside a square root the first thing you need to do is try to factorize it. First factorize the numerical term. Write down the numerical terms as a product of any perfect squares. Now split the original radical expression in the form of individual terms of different variables. Now you can pull out the perfect square numerical factors out of the radical. Similarly for the variable terms write the variables as power...
This tutorial explains how to save your work in Pinnacle Studio. The first step is to go to "File". Next is saving projects by using the drop down menu from the top left corner of the program. When you save your project it does not mean that all the video files will be saved. In fact, all the original files have to be stored in the exact same place so this will work. To save your new project you have to go to movie and make and output format like Vdix or VCL.
In this video the instructor teaches about inverse functions. Normally in inverse functions problems you are given a function that has a set of points and you are asked to find the inverse of that function. So if the function has a point in the form (x, y) then the inverse function has its points in the form of (y, x). Now when you are given a function f(x) that is in the form of x and asked to find its inverse, equate the function to y. Solve the equation to get the value of variable x in th...
If you have a fossil, you can tell how old it is by the carbon 14 dating method. This is a formula which helps you to date a fossil by its carbon. If a fossil contains 60% of its original carbon, how old is the fossil? The half life of carbon 14 is 5600 years. That means this is how long it takes for half the nuclei to decay. After 5600 years, if we start with a gram, we end up with half a gram. This rather complex formula shows you how to solve this puzzle using accepted scientific methods.
DrawingNow teaches you how to draw a pair of running shoes. Your start with two ovals, one larger than the other. These will act as the soles of the shoes. Next start sketching the shoe up and once you're happy with it, you can start drawing on top of it and erasing the original sketch. Do the same for the other shoe and start adding details. Draw the front of the foot, heel, the inside of it and the knots. Finally, all you need to do is color them in and use imaginative color combinations.
In this video the instructor shows how to solve a quadratic equation. If you have a quadratic equation with complex fractional terms and you find that a particular term is repeating then equate that term to a new variable and replace the variable in the given equation. Now try to get the equation a*x*x + b*x + c = 0, and solve for the roots of the equation which gives the values of the intermediate variable. But this variable was replaced instead of another term. So equate that term to the va...
In this video the instructor shows how to add and subtract rational expressions. When you have an addition or subtraction problem of rational expressions, first look and compare the denominator of all the terms. If all of them have the same denominator then the expression can be written as a fraction whose denominator is the original common denominator and whose numerator is the sum of numerators of all the other terms. Simplifying the numerator by adding and subtracting the like terms gives ...
In this video a professional boxer demonstrate the basics of boxing so that you can protect yourself. First of all, you should stand in such a manner that your left foot is in front and the right foot is in back (if you are right-handed). Make a fist, put both hands in front of your face. The distance between both the hands should not be much so that in any case, you can cover and protect your face. Your left hand should always turn up and pull back. For punching, take your right hand fist ne...

In this tutorial the instructor shows how to complete the square to graph a quadratic function using transformations. You can do this by transforming your equation in a series of steps. First make the coefficient of the square term to one by pulling out its numerical coefficient. Now to complete the square of the first part add half the coefficient of the variable with a degree one. Now to maintain the original value of the equation also make sure that you subtract the same value from the equ...

In this tutorial the author shows an easy and simple way of subtracting fractions with uncommon denominators. He says that to subtract fraction with uncommon denominator, we need to make their denominators equivalent first and after making the denominators equal, you need to increase the numerators proportionally to maintain the original ratio of the fraction. Now as the denominators are same, we can directly subtract the numerators arriving at a new fraction. He further shows how to deduce t...

This video will provide you with insight into how to find a number given its percent. In the example provided, you needed to find the number which 33 is 60% of. This was achieved by simply taking the number which is a percentage of another number, in this case 33, and divide it by the percentage, in this case 60%, or 0.6. By carrying out the long division from this step, you will be able to find the original number and solve this seemingly complicated problem with ease.

In this math tutorial the instructor shows us how to add three fractions with common denominators. He says that it is similar to adding two fractions with common denominator. He tells us first to add all the numbers in the numerator which gives us a new number which is the numerator in our answer and the denominator to our answer is the original common denominator. Now, if the resulting fraction is improper fraction, you will have to convert it into a mixed number. In this video the author sh...
The distributive property is a very important factor to consider in math and may save you a lot of trouble on your math homework. For values which lie right outside parentheses, you will need to distribute this value across the contents of whatever is inside the parentheses. You will need to multiply the value outside of the parentheses by first the first term inside the parentheses and then by the following terms inside the parentheses, distributing the value across all the terms found insid...

She shows how to do this by cutting up the square into sectors and arranging them in the form of a rough square and calcula...
In this arithmetic basics tutorial the author shows how to find the percentage of a number. He says that hundred percentage of number is the same number. He says that if we find the percentage of a number where the percentage is less that 100, then the value of the number reduces. Similarly if we find the percentage of a number where the percentage is more than 100, then the value will be more than the original number. He says that to find the percentage of a number we need to mark a decimal ...
