FACTORING COMPLICATED EXPRESSIONS Factoring Complicated Expressions - Concept. Carl taught upper-level math in several schools and currently runs his own tutoring company. He bets that no one can beat his love for intensive outdoor activities! When asked to simplify expressions, sometimes we come across complicated expressions that are not easily factored by traditional methods. GRAPHING LINES USING A TABLE OF VALUES Explanation. Transcript. When first introduced to graphing lines, we often use a table of values to plot points and connect them. There are several other methods of graphing lines, including using a point and the slope. Sometimes graphing lines using an equationPHYSICS SIPHONING
Explanation. Transcript. Siphons are tubes which draw fluid over the rim of a tank to a lower point. After an initial pressure change to initiate the flow, siphons operate continuously due to the pull of gravity. Torricelli's law says if a liquid flows from an opening in a container, its speed is the same as the speed that fluid would have if OPTIMIZATION USING THE CLOSED INTERVAL METHOD The closed interval method is a way to solve a problem within a specific interval of a function. The solutions found by the closed interval method will be at the absolute maximum or minimum points on the interval, which can either be at the endpoints or at critical points. Other ways of solving optimization problems include using thefirst
DETERMINING ORDER OF A REACTION USING A GRAPH In this particular segment, we'll take a look at tips and tricks for determining the order of a reaction using a graph. So you can always use experimental data that you have. SURFACE AREA OF JOINED SOLIDS Surface area is a two-dimensional property of a three-dimensional figure. When solids are joined together, such as a hemisphere on a cone, the surface area of the connecting circle is not included in the overall surface area - it is "hidden." Thus, to solve surface area of joined solids problems, determine which faces or bases are hidden and RATES OF DISAPPEARANCE AND APPEARANCE Here's some tips and tricks for calculating rates of disappearance of reactants and appearance of products. Here we have an equation where the lower case letters represent the coefficients, and then the capital letters represent either an element, or a compound. HOW TO GRAPH A LINE USING Y=MX+B How to Graph a Line using y=mx+b - Problem 1. To graph the equation of a line written in slope-intercept (y=mx+b) form, start by plotting the y-intercept, which is the b value. The y-intercept is where the line will cross the y-axis, so count up or down on the y-axis the number of units indicated by the b value. DETERMINING IF A R-GROUP IN AN AMINO ACID IS POLAR OR Identifying Amino acids can be difficult. So here are some tips for figuring out if an R-Group in an Amino acid is polar or non-polar. This first set that I'm going to show you, are all the non-polarR-Groups.

They also discuss Chemistry's approach to commontopics like
DIVIDING RADICALS AND RATIONALIZING THE DENOMINATOR When dividing polynomials, we set up the problem the same way as any long division problem, but are careful of terms with zero coefficients. For example, in the polynomial x^3 + 3x + 1, x^2 has a coefficient of zero and needs to be included as x^3+ 0x^2+3x+1in the division problem. denominator numerator rationalizing the denominatorconjugates.
ECONOMICS: COST & REVENUE Explanation. Transcript. One of the most important parts of economics is knowing the revenues and costs and how they relate to increased production. These can both be modeled by functions. These cost and revenue functions can then be manipulated like any other function. The profit is the difference between total revenue and total cost.STANDING WAVES
Standing waves, also known as stationary waves, are waves formed by the combination of two waves with equal amplitudes and frequencies. Because of the interference between these waves, standing waves don't travel at all. There are points along the wave, called nodes, which don't seem to move at all but vibrate in place. HOW TO GRAPH A LINE USING Y=MX+B How to Graph a Line using y=mx+b - Problem 1. To graph the equation of a line written in slope-intercept (y=mx+b) form, start by plotting the y-intercept, which is the b value. The y-intercept is where the line will cross the y-axis, so count up or down on the y-axis the number of units indicated by the b value.

So in our example here, we're given Cu2+ plus Br- yields CU+ plusBrO3-.
THE MIDPOINT AND DISTANCE FORMULAS IN 3D The Midpoint and Distance Formulas in 3D - Concept. Norm was 4th at the 2004 USA Weightlifting Nationals! He still trains and competes occasionally, despite his busy schedule. There are two formulas that are important to remember when considering vectors or positions in the 3D coordinate System. The midpoint formula and the distance formula in3D.
SOLVING FOR A PARAMETER IN A LINEAR EQUATION solving for a parameter variable. Solving for a parameter, so a parameter is a fancy way of saying a variable. So in this example what we actually want to do is solve for a variable x okay. And this may look a little bit daunting because we have, what 5 letters up there but how we actually do it is very similar to the stuff we've solvedbefore.
