This is a video tutorial in the Education category where you are going to learn how to balance a chemical equation step-by-step. The left side of the equation is called the reactants and the right side is the new products. What will be new products when silver nitrate reacts with ferric chloride? The left side will be written as Ag NO3 + Fe Cl. The valence of Ag is +1, NO3 is -1, Fe is +3 and Cl is -1. On the right side the silver cannot go with iron because both are positive. So, it will be ...
In this tutorial, we learn how to write equivalent fractions. If you have a negative in front of the fraction, it's the same as writing the negative on the numerator or the denominator. If we would have a negative on the top and on the bottom, this would cancel both out to create a positive, which wouldn't be right. To write the fractions, simplify it. If it's already simplified, you will need to multiply the fraction. After you do this, you will finish the equation and have it written out in...
This is a video tutorial in the Education category where you are going to learn how to do fraction multiplication. Before multiplying two fractions together by multiplying across the numerators and the denominators, you should always try to cross cancel as your 1st step. For example in the problem, (-15/4) x (14/5), 15 and 5 will cross cancel to 3 and 1. Similarly, 14 and 4 will cross cancel to 7 and 2. So, what you will get now is (- 3/2) x 7. Also you should take care of the signs. In this ...
In this tutorial, we learn how to find abc, curve direction & y-intercept (quadratic eq). First, you need to find the a,b, and c of the equation. A will equal what the coefficient is in the equation, B will equal the second, and C will equal the third term. This tells us if the numbers are positive or negative, so so know if the parabola opens up or down. To graph C, you will know what the y-intercept is going to be, then find the matching units. After this, you will use B to shape the parabo...

If the only way you know how to show a girl you dig her at the movie is the old "yawn and lean your arm over her shoulder" move, then you're clearly not getting any. When you're taking a girl out for a date at the movies, there's a fine line to be drawn between scary and creepy (fondling her a wee bit too soon) and just boring (sweaty palms, not approaching her at all). So how do you walk that fine line from first date to second date?
In this tutorial, we learn how to train your dog to close a door. To do this, you must first have a positive approach and a motivator that your dog enjoys.

Train your dog with first giving them a post it note and giving them a treat when they touch it with their nose and making a click noise. Keep doing this, and when the dog is by the door, have them shut this and they will underst...

Solving the Inequalities using graph, first you have to take the inequality equation into equal. Then convert the equation into straight line equation i-e(y=mx+c). Giving own values for 'x' like (-1, 0, 1) we would get the value for 'y'. By plotting these points in the graph, you will get an straight line. If the given equation is greater than symbol, shade towards the positive part. If the given equation is smaller than symbol, shade towards the negative part. This is an one method to solvin...
A factoring problem that has to be solved by grouping is easy to identify, because you can always identify if there are any similar terms in a polynomial. Now, if you find any variable common in any terms pull them out as the common leaving the rest of the terms. After pulling out the common terms you can group the rest of the polynomial. Be careful while pulling out signs. Pulling out a positive number does not effect the signs of terms in the polynomial, where as pulling out a negative numb...
User DayTeacher helps you understand integers and the number line. When numbers were conceived, man had the basic concept of small numbers. The first things you learn in a language are numbers. The weather might have had an impact on numbers, as temperatures dropped below 0. When talking about years Before Christ (BC), you could say 1000 B.C. is actually -1000.

In this video the instructor shows how to find the slope of a line given two points that like on the line. Slope of a line is the measure of the steepness of the line compared to the angle made by the line with the x-axes. A line with positive slope slants forwards and a line with a negative slope slants backwards and a line parallel to x axes has zero slope. So if you are given two points (x1, y1) and (x2, y2), the slope of the line passing through those two points is equal to m = (y2 - y1)/...
In this video the instructor shows how to solve quadratic equation by the square root method. The square root property of equations states that if k is positive and a*a = k, then a is equal to square root of k or -1 times the square root of k. So to solve a quadratic equation by square root property first get the equation in the form of a*a = k. Now apply the square root property explained in the previous step to get the result. The instructor now demonstrates these concepts by solving some e...
This video shows the method to simplify expressions with different exponents. The video starts with the explanation of 16 raised to the power 1/4. This can be solved by taking the nth or the 4th root of 16 where n stands for the denominator of the fraction. Then the video explains 8 raised to power 4/3. This can be solved in two ways. First one involves taking the cube root of 8 and raising it to the power of 4. The second method involves converting 8 into 2 raised to the power 3 and taking t...

YouTube user NotesCollegeAlgebra teaches you how to interpret a graph. You will learn how to read it and extract information. You go to the graph to see that f(-4)=-2. f(1.5)=2, so it's positive. You then have the question: For what x-values is f(x)<0? You go to the graph and see that you come up with (-5,3). The x-int is (3,0) (4,0). The y-int is (0,4). The domain is (-5,4) and the range is (-4,4). You then have the question: how often does y=7/5 intercept the graph? The answer is 4 times. T...

In the last example, he demonstrates...
This video will demonstrate exactly how to shift a graph on a x,y axis. When shifting a graph on the x axis you will need to replace x with x-h; where h is the variable to shift the graph. No matter how far you need to shift a graph, h is always the number of units you are shifting; shifting up or right is represented as a positive and down or left is negative. Just plug in your units into your equation and you will have your shifted graph.

It has nothing to do with you, it has to do with him. She recommends not wasting time ...
To find a vertical asymptote, you are trying to find values of x that produce 0 in the denominator but not in the numerator. If 0/0 occurs, that means you have a "hole" in the graph. A vertical asymptote is a place in the graph of infinite discontinuity, where the graph spikes off to positive or negative infinity. To find the vertical asymptote, set the denominator equal to zero and solve for x. Check that the values also do not give a zero in the nominator. If the values work, you have found...
It’s just a few steps to make a toy motor. Take a battery of any brand, then take two safety pins. Attach them to both the sides of battery as they act as positive and negative. Then take a magnet, keep it on the battery. Now take a strip, which is rolled into a circle, and take two leading wires from it. Then keep this strip in between the safety pins and just start it up by rotating to one side. Then leave it aside, it rotates continuously.

Like a lemon, a potato can produce electricity. This science experiment was prepared by Ebtisam Al Anzoor and demonstrated by Mustafa Daif. The electricity is proven using an analog micro ameter. The positive is copper from a penny or copper coin while the negative is a galavanized nail. The potato releases a charge and is further proven when it is connected to a calculator. You can daisy chain the potatoes for a greater charge.

Welcome back, my tenderfoot hackers! Generally, you will want to perform a vulnerability scan before doing a penetration test. Vulnerability scanners contain a database of all known vulnerabilities and will scan your machine or network to see whether those vulnerabilities appear to exist. If they do, it is your job to test whether they are real and can be exploited.
