This video is about Annual percentage Rate(APR) and the Effective APR rate.The video begins with an example of a credit card which has a APR rate of 22.9% and daily periodic rate of 0.06274%.You can get the APR rate by multiplying the daily peiodic rate with 365, which in this case will be 0.06274*365 which is equal to 22.9.If you convert the daily periodic rate into decimal values , it will be 0.006274.So for example, if you have 1 dollar in your balance on day 1, on day 2 you will owe 1.000...

In this video the instructor shows how to factor the difference of squares using a formula. The formula to find the difference of squares can only be applied if you have two perfect squares. The formula is (a * a - b * b) = (a - b) * (a + b). That is the difference of squares of two numbers is the product of sum of two numbers and difference of two numbers. So when you need to find the difference of squares of two numbers substitute the values in the above formula to directly solve for the fa...

In this video the instructor shows how to factor the GCF and difference of squares. When you are asked to factorize a number or monomial or a polynomial, the way to do is break it down into individual terms. When asked to factorize a binomial, try to pull out any common terms and factorize the simplified equation. When you are asked to factorize the difference of squares use the general formula which states that the factors of (a*a - b*b) is (a-b) * (a+b). Now substitute the given values in t...

In this tutorial, we learn how to demonstrate the difference between land & sea ice. First, fill up two large aquariums with water, then add in a glacier to one aquarium and an iceberg in the other. This will see how the water level changes based on the melted of each different ice item. Draw a line at the water line where it started at, then when the ice melts, check the water levels. When finished, see what the water levels have ended up at. Now you will be able to show this to your student...

To write the sum or difference of logarithms as a single logarithm, you will need to learn a few rules. The rules are ln AB = ln A + ln B. This is the addition rule. The multiplication rule of logarithm states that ln A/b = ln A - ln B. The third rule of logarithms that deals with exponents states that ln (M power r) = r * ln M. Using these three rules you can simplify any expression that involves logarithms to arrive at a single logarithm. The instructor shows how to apply these rules to a f...
