In Advanced Algebra, we discussed a new section 10-2: Logs and Log Functions. This lesson follows from exponential functions. That is, y =(b)^x can be translated to
x = log (base b) of y. For example, 9 = 3^2 is also 2 = log (base 3) of 9. Also, we talked about 3^(2x) = 9^(4x-1). It is the same as 3^(2x) = 3^2(4x-1), because 9 = 3^2. This sentence translates into 3^(2x) = 3^(8x-2). Since that have the same base, work with the exponents. 2x = 8x-2. Solve for 'x'. x = (1/3). We mentioned that log (base b) of y - log (base b) of v = log (base b) of (y/v). Tomorrow we will talk about the addition of logs with the same bases. The homework is pg. 608-609 #18-20,31-39.
In Geometry, we discussed the Tessellation (final special project) Project in class. The instructions sheet is self-explanatory.
Tessellations Project

It is due on May 26, 2009. Tomorrow we will tackle Area of Parallelograms. The homework is to work on the template and design of your tessellation.
Be Safe!
