Algebra 2H pds 1,2
We went over questions from the hw on mixture and rate word problems. Then, we began the lesson on Graphing Systems of Inequalities.
HW page259 # 1,3,5,9,13, and 21.
EC problem # 18.

Geometry H pds 3,5
Today, we learned the formula for finding the sum of the interior angles of any polygon. The formula is: 180(n-2), where n = the number of sides of the polygon.
HW Worksheet-Puzzle...Do all problems, and show the work!
EC problem...The angles of a pentagon are 150º,120º,80º,140º,50º. Extend each side, and find the measure of each exterior angle. what is their sum? If done correctly, I'll give 4 ec points!

Trig pd 4
I went over quiz questions, hw questions, and then attempted to explain the cycle (period) of the sine and cosine graphs. The formula is 2 pi/b where y = a sin bx.
