__October 13, 2009__
Chapter 2.1 Order of Operations. Theory p.88-89 Practice p.91 # 57-69 odd, p.946 (top, lesson 2.1) # 17-31 odd Graphing calculator keystrokes p.150 less.2.1 Chapter 2.2 Properties of Exponents. Theory p.95, Ex.1 p.96 __October 15, 2009__ Chapter 2.2 Properties of Exponents Practice p.99 #27-37 odd (see example #4 p.97) p.99 #39-61 odd (see examples #2-3, p.96) __//Homework// issued on 10.15 for 10.16.2009__ p. 99 # 34-50 even __October 16, 2009__ Chapter 2.3 Introduction to Functions Practice p.108-109 # 21-45 odd (see examples #1-5, p.103-106) __Homework assigned on 10.16 for 10.19.2009__ p.108-109 #22, 24, 32-46 even __October 19, 2009__ Chapter 2.4 Operations with Functions (Perform operations with functions to write new functions).Operations with functions are listed in the blue section of the top of the page 112. Read examples 1 and 2 on page 112. Then try to reproduce these problems on your own. If you make a mistake, read the the textbook solution again. Again, try to solve the examples 1 and on your own (without looking in the textbook). If you still have problems, you have to review the distributive properties (example 2 p.88) and properties of exponents (example 2 p.96). Practice p.115 #11-29 odd. __Homework assigned on 10.19. for 10.20.2009__ p.115 #14,16,20-34 even. To solve these problems, study examples 1 and 2 on page 112 and look for the advice above. __October 20, 2009__ Chapter 2.4 Compositions of Functions. The definition of composite functions and abbreviations are on p.113. Carefully study example #3 on page 113. Practice p. 115 #35-49 odd. __Homework assigned on 10.20 for 10.21.2009__ p.115 #36-46 even, 52-56 even. Hint for # 38 p.115. See the link below Keystrokes for #44 and 46 on p.115 are listed below. Click on the link. Note that in #44 we enter Y1 after VARS, and then Y2 after VARS. In #46 we enter Y1 both times after VARS. __October 21, 2009__ Constructed Response # 4 (link below) __October 22, 2009__ Chapter 2.5 Inverses of Functions. Definition of Inverse of a Relation (blue section on the bottom of the page 118). Study examples #2 and #3 on page 119. Practice p.122 #11-25 odd, p.122 #29-39 odd. __Homework assigned on 10.22 for 10.27.2009__ p.122 #18-26 even and #30-38 even Study example #2 on p.119 before you start working on #18-26. In 18-26 switch //x// and //y// to find Inverse of a given relation. The relation is a function if all //x// in a given relation are different. You have to make a decision for both an original relation and its inverse separately. Carefully study example #3 on page 119 before you start working on #30-38. In these problems use //y// instead of //f(x), g(x),// and //h(x).// Then substitute //x// for //y// and //y// for //x.// Finally, solve for y. Hints for #34-38 are in the link below. =GEOMETRY.=

__October 13, 2009__ Review definitions of Pair of Vertical Angles, Linear Pair of Angles, and Pair of Supplementary Angles p.50. Review how to use a protractor p.39 Chapter 2.5 Angle Relationships. Theory p.120-121 (Investigations 1 and 2), example p.121-122. Practice #5 p.123. __October 15, 2009__ Chapter 2.6 (p.126-) Discussed definitions (in bold) on p.126. Went through conjectures C-3a, C-3b, C-3c, C-3 on p.127. The empty spaces with questions marks contain the word **__congruent__**. Also conjecture C-4 on p.129. the empty space contains the word **__parallel__**. Practice p.129-130 #1-6. __Homework assigned on 10.15 for 10.16.2009__ p.130 #7 (17 points), p.122 #3 (4 points), p.123 #4 (9 points) October 16, 2009 1a Find terms in sequences: p.97 #3-10 1b Know and apply the difference between **inductive** (p.94) and **deductive** (p. 100) reasoning 2 Draw consequent shapes in picture patterns: p.97 #11-16 2b Know the difference between inductive and deductive reasoning 3 Write functions rules for **sequences** and drawings: p.109 #1-6 4-5 Identify **linear pair and vertical angles**: p.120-121; p.122-123 #1-6. Construct simple linear equations and solve, e.g., //78 + (x+10)=100. Solution: 78 + x + 10=100, 88 + x = 100, x=12// 6-7 Identify **corresponding, alternate interior and exterior angles**: p.126. Also know Converses p.127 (C-3a, C-3b, C-3c, C-3), p. 129 (C-4). (The converses are inside rectangles). Practice: p.129 #1-3, p.130 #6. 8 The right angle is divided into two parts. One angle is 1part., another is 14parts. What are the measurements of the angles? Solution: //x + 14x =90//, //15x=90, x=6// One angle is 6 degrees, another one is 90-6=84, or 14 times 6 is 84. Answer 6 and 84. 9. Find the **slope if coordinates** of two points are given. Formula and examples: p.133. 9a Make a grid using your ruler and plot the points. 10. Identify 3-D shapes p.81 (top of the page) 10b. Identify bases that are polygons (polygons p.54). //Bonus Questions will be given at my discretion. You can only use notebook on this test. Please, bring small a ruler. You do not need textbook on the day of the test, on Monday October 19th. Additional time to finish the test will be given only to the students who came on time on the day of the test. The students who get 90% on this test will have a privilege to take Chapter 3 test home next time provided they have a good behavior effort, come on time to every class, carry all necessary materials to the class, do their homework and most of the work in class.// __October 19, 2009. Chapter 2 Test. October 20, 2009__ Chapter 3.1 p.142-. Study and reproduce investigation #1 on p.143 and #2 on p.144.

Know the definitions (in bold on p.147) of a //segment bisector// and //perpendicular bisector.// Perpendicular Bisector Conjecture C-5 on p.148 (in blank space write //equidistant.// Equidistant means equal distance.) Know Converse of the Perpendicular //Bise//ctor Conjecture C-6 on page 149 (in the blank space write perpendicular bisector). Definitions of //median// and //midsegment (//in bold on p.149). Practice: p.149 #1-5; p.150 #7. __Homework assigned on 10.22 for 10.27.2009__ p.150 #7-10.
