Solving nonlinear equations by graphing
Analyzing an argument for validity
Understanding probability is a useful skills. It allows you to make informed choises that are not based on subjective feelings but an understanding of reality.
Let's revise the theory:
Here's an example of a real life situation where probability is useful.
Athletes and coaches use probability to determine the best sports strategies for games and competitions. A baseball coach evaluates a player's batting average when placing him in the lineup. For example, a player with a 200 batting average means he's gotten a base hit two out of every 10 at bats. A player with a 400 batting average is even more likely to get a hit – four base hits out of every 10 at bats. Or, if a high-school football kicker makes nine out of 15 field goal attempts from over 40 yards during the season, he has a 60 percent chance of scoring on his next field goal attempt from that distance. The equation is: 9/15 = 0.60 or 60%
Here's a good website for excercises
Let’s learn the theory:
1. A dining-table is marked for $7500 and is sold for $6000.
2. In Las Vegas, Nevada, stores charge a 4.6% state sales tax and a 3.65% county sales tax. Yuki is purchasing a handbag priced at $220before tax. How much sales tax does Yuki pay for her handbag purchase?
Interest and amortization
Once you enter adulthood, you will be faced with many responsibilities. You will have to understand new concepts that have a direct effect on your life. Understanding finances can save you a lot of money and help you make wise decisions. Buying your first house or apartment might happen sooner than you think. It’s worth getting ready to understand how to calculate interest and amortization.

Calculating average speed and distance travelled
Mathematical equations can be used to solve many everyday life situations. Calculating the average speed of an object is one of them. However, perhaps a much more useful skill is the ability to tell someone who is waiting for you to finish your journey, at what time you will arrive.

Rate of change
Everything that you study in Math has a practical application. Here are some practical applications for average rate of change:

3. What are the coordinates when the above points are mirrored according to the y-axis?
4. Draw a triangle A(-1, 3), B(-2, 0) and C(2, -1). Mirror the triangle by the point (0, 1), What are the vertices of the mirrored triangle?
Some of the practical applications of the Pythagorean theorem include marine navigation, building almost anything (houses, bridges etc.) and figuring out which TV-size to choose (sizes are given as diagonals, so you don’t know the hight and width).
Here are some excellent online exercises of the Pythagorean theorem:
Prime numbers are numbers that are divisible only by themselves and 1.
