In this tutorial the instructor talks about various strategies for solving equations and inequalities involving absolute value. To do this the first step is to isolate an absolute value. An absolute value is exactly equal to a number. If that number is less than zero then there is no solution. So, if you have an absolute value that is less than a number it means that the real value lies in between negative and positive value of that number. If your number is less than zero then it is empty se...
Ever wanted to know how to make a fire with your cell phone? All you need is a cell phone, a brillo pad, and material for tinder. First take the battery out of your phone and find the positive and negative contacts on the bottom of it. Next tear off a chunk of the brillo pad, roll it up until you have a twisted piece about an inch long. Bend the steel wool over and touch an end to the positive and the other end to the negative contacts on the battery. That causes the steel wool to smolder--no...
Richpin demonstrates how to test an alternator with a standard multimeter. First make sure that the vehicle's battery is fully charged. Take the negative lead of the multimeter and put it on the negative post of the battery. Place the positive lead of the meter on the positive lead of the battery. Set the meter to DC voltage using the 20 scale and read the display to ensure the battery is fully charged. Next start up the vehicle and see what the alternator is producing. The display should now...
This is the demo showing how match quadratic equations in the graphs. Plug in x=0. So everything with x cannot disappear. There is only one negative three in the equations. Let's look at the equations that has the four as y in the set. One of the difference between each equations are the negative in front of the x square and not in the second one. B is the set which opens down and C is the set which opens. Now lets look zero as y on each set. Both of them are opened. Let's look at X intercepts.
This is the video about how to evaluate square roots. The square root of a number is a number that you can square to get it, that is, a number that you can multiply by itself to get the number. So, 2 is a square root of 4, because 2 x 2 = 4, and 3 is a square root of 9, because 3 x 2 = 9. (-2) x 2 is also 4 and (-3) x 2 is also 9. Numbers that have square roots always have two, a positive one and a negative one, but the square root symbol means only the positive one, so we can have one answer...
This video teaches you how to test for symmetry algebraically. You will need to know the basic formats of graphs and the (x,y) setup. Once you get your equation of the line, you will need to replace y with negative y and x with negative x and solve the equation. You will need to solve for x and also for y for the odd and even. If the equations do not equal each other then they are not even or they are not odd. If this is the case then the lines are not symmetrical and that is how you test for...
This is a great video presentation of how Sodium Potassium Pump can maintain a voltage gradient across a cell. It also discusses various things like the differences between positive and negative charges and positive and less positive charges etc. The video tries to explain a lot of things happen within a cell when you fluctuate the voltage of sodium as well as positive and negative ions within a cell. You must watch it yourself to see the changes happen within a cell when you make some changes.
If you watch this video, you will learn what slope is, and how to find it. Slope is defined as rise divided by run, where rise in the increase the Y coordinate and run is the increase in the X coordinate. For example, if you pick two points, you can travel from the left point to the right point. However many points you go is the run. How far up you go is the rise. For example, if your rise is 4 and your run is 2, then you divide 4 by 2 to get your slope, 2. When you're finding the rise, if yo...

This video explains how to use jumper cables to jump start a car. First, determine that a dead battery is the reason your car is not starting. If the engine cranks when you turn the key, the problem is not the battery and jump-starting won't help. If the windshield wipers, lights and heater blower all work, the battery is probably fine and you may have a bad starter. A jump-start won't help if you have a bad starter. If you hear no sound at all when you turn the key or if the engine cranks ve...
The future of forests looks dreary in the face of a warming climate, but scientists are exploring the relationship between soil microbes and the ability of trees to move to higher altitudes, a key component of their survival.
If your car has a dead battery, jumper cables can be used to connect to a car with a good battery to start your engine. Begin by positioning the two cars side-by-side, turn off the engines, and lift the hoods to access the batteries. First, attach the red cables to the positive terminals of each battery beginning with the dead battery. These terminals are usually marked with a plus sign or in red. Next, attach the black cable to the negative terminal of the good battery. The negative terminal...
The video shows how to solved mixed property problems using the exponent rules. See if there are any rules you can apply to the problem until you get to a point where you can't simplify anymore. The instructor shows in the example problem that the two bases are the same, but there is extras happening the numerator. The power to power multiply rule is applied removing the extra issues from the numerator. Next the quotient rules is applied as there is the exact same base to the power so we keep...
This video teaches us the concept of nth roots. The video starts with the square root of constants. We find the number which when multiplies by itself for two times results in the constant inside the square root. Then we find the square root of variables. Here again the same concept is used. We find the variable which when multiplied by itself for two times results in the given variable. Then we find the cube root. Here we find the number which when multiplied by itself for three times result...

Taking this formula 9x²+y²=9 your instructor shows you how to find the solution for the variable y. Finding a second derivative is no more difficult that finding the first derivative, you only have to do the problem equation through twice. The derivative of 9x² will be 18, of y² will be 2y [this is the same as 2(y), 2 x y or 2 * y]. The problem now goes -18x + 2y dy/dx=0. This equation is solved for dy/dx making the next step in the problem go -18x 18x+2y dy/dx=0-18x, 2y dy/dx= -18x. The next...
