Logs in the Real World How do you use logarithms in the real world? Like most things that we are taught in math‚ most people would not be able to answer this question. Though many people have no clue how to use a logarithm in the real world or have ever needed to use one‚ there are still many uses for logs that are actually quite common. Three common uses for logs in the real world are calculating compound interest‚ calculating population growth or decay‚ and carbon dating. Using logs is a key

MATHEMATICAL FORMULAE Algebra 1. (a + b)2 = a2 + 2ab + b2 ; a2 + b2 = (a + b)2 − 2ab 2. (a − b)2 = a2 − 2ab + b2 ; a2 + b2 = (a − b)2 + 2ab 3. (a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca) 4. (a + b)3 = a3 + b3 + 3ab(a + b); a3 + b3 = (a + b)3 − 3ab(a + b) 5. (a − b)3 = a3 − b3 − 3ab(a − b); a3 − b3 = (a − b)3 + 3ab(a − b) 6. a2 − b2 = (a + b)(a − b) 7. a3 − b3 = (a − b)(a2 + ab + b2 ) 8. a3 + b3 = (a + b)(a2 − ab + b2 ) 9. an − bn = (a − b)(an−1 + an−2 b + an−3 b2 + · · · + bn−1 ) 10

Algebra is a branch of mathematics that uses mathematical statements to describe relationships between things that vary over time. These variables include things like the relationship between supply of an object and its price. When we use a mathematical statement to describe a relationship‚ we often use letters to represent the quantity that varies‚ since it is not a fixed amount. These letters and symbols are referred to as variables. (See the Appendix One for a brief review of constants and variables

Jasmine Chai Grade 10 196298501 Patterns within systems of linear equations Systems of linear equations are a collection of linear equations that are related by having one solution‚ no solution or many solutions. A solution is the point of intersection between the two or more lines that are described by the linear equation. Consider the following equations: x + 2y = 3 and 2x – y = -4. These equations are an example of a 2x2 system due to the two unknown variables (x and y) it has. In one of
