This educational math video describes the steps necessary to solve an equation involving absolute values. "Absolute value" refers to the magnitude of a quantity and is always expressed as a positive number. You can think of absolute value as the distance a number would be from zero if plotted on a number line. Positive 17 and negative 17 both have the same absolute value because both are 17 units from zero on a number line. Because of this, all absolute value problems have two answers, one wh...

Pricing, availability, and software selection are all issues that will have to be addressed before widespread adoption will start.
Last week, the U.S. Justice Department issued criminal indictments against seven Iranian hackers. These hackers, working for private companies in Iran, are accused of orchestrating DDoS attacks against U.S. financial institutions from 2011-2013 as well as intruding into the control panel of a small dam in Rye, New York. It is thought that these attacks were a response to the U.S. tightening financial restrictions on Iran during those years and the NSA-based Stuxnet attack on their uranium enr...

In this video, we learn how to find the volume of a swimming pool. To do this, you will first need to find the measurements of all the sides that are on the pool. After this, you will plug in the measurements that you found into the equation to find the volume. This equation is: V=AH, volume= area(height). So, plug in the area and the height to the equation for A and H and then multiply these two together. Once you do this, you will find the answer! Don't forget to label the units on the fina...
In this video, we learn how to understand completing the square. First, you will write the quadratic expression out. Then, you will write the open bracket so you write it out in the correct format. Now, find the number in front of the 'x' term, which is the coefficient. Then, write this number on the other side of the equation in the parenthesis. From here, you will need to follow the proper rules of math to find out what the square is equal to. When you are finished, make sure you label the ...
In this tutorial, we learn how to find the arc length of a function. All you're doing when finding arc length is finding the curve between 'a' and 'b'. Imagine this as a string you're pulling straight to see how long it is going to be. The formula says if your function is in 'y=x' you have to take one times the derivative squared. This is a basic formula that you will use to find the arc length. When you plug in your values to this equation, you will find the answer. Practice with the example...
In this tutorial, we learn how to find the area of a circle. The line from the middle to the edge of the circle is called the radius. Find what this is in your equation, then multiply (3.14 X radius x radius). This will always work out the area of a circle for you. So, do this equation with your calculator or by hand, then you will have the correct answer for the area. Make sure to add the units squared after you get the answer. If you are given the diameter (line all the way across), you wou...
In this video, we learn how to find the area of a trapezoid. The formula to figure out how to find the answer is: Area= 1/2x (base1 x base2) x height. Now, find the bases and the height of the trapezoid. Remember that the height must always be perpendicular to the bases. Once you have found these, add the bases and multiply by the height. You can use a calculator to do this or do it off hand if you're good with math. For the third step, divide the answer by 2 and then write down the answers w...
In this tutorial, we learn how to find the interior and exterior angles of a triangle. I triangle has three angles and their measurement when added together will equal 180. For example, if one angle is 80 and another is 30, then start off saying the equation equals 180. Write in 80+30+X in front of the equals sign, then subtract the combined like terms from the 180. After this, you will have found the value of x, which will also be the measurement of the last angle. Make sure to write out the...
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...

In this video tutorial, viewers learn how to find the area of a rectangle. The formula for finding the area of a rectangle is: A= b x h. The base is the horizontal bottom lie of the rectangle and the height is the vertical straight line of the rectangle. Whenever working with area, users must square the unit of measurement. To find the area of a square, multiple the side of the square twice (square it). This video will benefit those student viewers who are struggling with math, and are in nee...

In this how to video, you will learn how to re-size an image for printing using Photoshop. First, open the image you want to re-size in the program. Next, go to image and select image size. From here, you will see the current size of the image. You can change the units of the sizing. The resolution is the number of dots printed per inch. De-select re-sample to change the resolution of the image only when printing. 300 is the standard resolution. When you re-size the image, make sure constrain...
In this video tutorial, viewers learn how to find an angle using alternate interior angles. Make sure that the angles are alternate interior angles. Alternate interior angles are angles that are on the inside of the parallel lines, and on the opposite side of the transverse. The transverse is the line that passe through the two parallel lines. If both angles are inside the line and are opposite to the transverse, then they are alternated interior angles. If you know two angles are alternate i...
This video shows the method to find the length of the total segment using the midpoint. Let the total line segment be PS. Let Q be the midpoint of PS. Let R be a point on the line segment QS. The first step involves the use of midpoint to find out the length of QS. We are given that QR = 1 and RS = 4.5. QS is equal to QR plus RS which is equal to 5.5. Now since Q is the midpoint of PS the total length of the segment PS is equal to twice the length of the segment QS. This is equal to 11 units....
Chad from California Waterscapes takes you through the steps of installing a backyard pond. He begins by marking the location for the pond and stream using spray paint on the ground and by laying out the necessary equipment: the skimmer box and the waterfall unit. After digging out the pond Chad uses a laser level to determine the water level and place the skimmer box at this level. After all debris has been removed from the pond the underlayment and liner is placed in the pond followed by ro...

In this video, you will learn how to find the area of a rhombus. The formula is A = 1/2 d1 * d2. The d1 is the diagonal inside the rhombus, while d2 is the other diagonal inside the rhombus. You will need to find the length of these lines in order to complete the formula. For example, if one length is 5 and the other is 4, then you should plug in the numbers into the formula. This will equal 20 divided by 2, or 10. 10 units squared is the answer to this particular problem. Viewing this video ...
An atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged ions.
