HW #1 Due on January 14, 2020

• 1.1: 22 – 24
• 1.7:  55 – 58
• 2.1:  63 – 67
• Learn time tables and write all of them out as follows:

1 x 1 = 1

1 x 2 = 2

…. until 12 x 12 = 144

• Read Ch 5
• 5.1:  3 – 66 by 3; 3, 6, 9, 12, etc.
• 5.1:  78, 79, 81

HW #2 Due on January 21, 2020

• 5.2:  12-16
• 5.4:   18 – 30 by 3
• 5.4:    42 – 66 by 3
• 5.4:    84, 85
• 5.3:    3 – 33 by 3
• Read all sections of chapter five carefully, skip 5.5, and especially look at any of the exponent rules.

HW #3 Due on January 28, 2020

• Please memorize all exponent rules, which means to memorize the names, a sentence for an explanation, an equation using a and or b as a base.
• In section 5.6, there is a nice summary of rules at 5.6.5.
• On homework, write out all seven exponent rules, with names, definitions, equations with a and b as bases, and an example with x or y and numbers as exponents.
• 5.2:  6 – 66 by 3.  Note: When evaluating a constant to an exponent, watch the base.  -3² has a base of 3 and thus we take 3 times 3 and put a negative in front so the answer is – 9.  If a problem has (-3)², the base is (-3) and then (-3) time (-3) is 9.
• 5.6:  5 – 125 by 5
• 5.7:  3 – 114 by 3
• Test on January 30, 2020 on Chapter 5, also from chapter one on solving an equation and evaluate (substitute value) and 6.1
• Read 6.1

Test #1 on January 30, 2020

• From Section 6.1 know how perfect squares and square roots of perfect squares from 1 squared to 15 squared.
• Problems from 6.1 are 3, 4, 15 – 24, 27 – 30.

HW #4 Due on February 4, 2020

• Please read these notes and write the notes into your notebook.
• Read 6.1 and 6.2 very carefully and read the other sections in Chapter 6.

• 7.2:  12 – 24 by 3
• 7.2:  43
• 7.3:  3 – 12 by 3
• Test on Thursday, 2/27

Test # 2 Preparation for Test on February 27, 2020

• Test is on Ch 6 [Radicals and Rational Exponents] and Ch 7 [Solving Quadratic Equations]
• Please make up a test and take it by using problems and information from the following sections.
• Know the following:
  • Standard Form of a Quadratic Equation found in 7.2.1.  Make sure to note that a cannot be zero.
  • Quadratic Formula and its use found in Fact 7.2.2. The Quadratic Formula.
  • 7.1.2 The Pythagorean Theorem and its use.
  • 6.3.2 Radical and Rational Exponent Rule.
• Problems in 6.5
  • 5, 7, 9, 15, 17, 31, 35, 41 (Use rational exponents), 55, 57
• Problems in 6.4
  • 31
• Problems in 7.5
  • 5, 7, 9, 15, 17, 21, 29, 33, 35
• Problems in 7.4
  • 47

HW #8:  Due on March 3, 2020

• We are going to Chapter 9 next and then back to Chapter 8.
• Read these notes on graphing.  Pay special attention to Page 3 and notice all of the steps to substitute in values.  These notes are also found at:
  • pcc.edu/staff/wdiss/notes under Graphing
• Using the steps found in the document, notes, do the following problems in 9.1:
  • Use a table of five values to do problems 13 and 16  [For Problem 16 use values of -8, -4, 0, 4, 8.  The steps are on Page 3.
• Problems 13 and 16 should have resulted in a line.  One can use a table of values to graph other problems such as a parabola.
• Please read 9.2 and 9.3 carefully.
• Use of table of values and graph the  following equation, which will be a parabola on a graph.  Use values of x, -2, -1, 0, 1, 2, 3, 4
• 
• Now read these notes to find out to graph a parabola using key features.  Parabola Notes
• Please use the parabola notes and graph
• 
• and graph problems 33 and 35 in section 9.3.

HW #9:  Due on March 10, 2020

• We are going to Chapter 9 next and then back to Chapter 8.
• Use the steps from March 5, 2020 and graph the two following parabolas.   Recall you need to do steps to find vertex and find the x-intercepts. The rest of the information can be extracted from the constants, a, b, and c.  Please set up the table with the key graphing features which are the following:
  • Constants, a, b, and c
  • Open Direction
  • Vertex (… , …)
  • Axis of Symmetry x = …
  • y-intercept  (0, ….)
  • x-intercept   (…, 0)  and (… , 0).  Note: There may not be x-intercepts, or two or one.
• 9.3:  36, 37.  Note on #37, there is only one x-intercept point, so substitute in the value of one for x, and solve for y.  You can then use the point at (1, …) and then plot the reflection point on other side of axis of symmetry.
• 9.3:  53 parts and b.  You DO NOT need to graph this equation, but go through the process to find the vertex and the x-intercepts to answer the questions.
• 9.3:  57:  find the vertex and if it is above zero, then plane will not hit the ground, else … bummer ….
• Read chapter 8 carefully.
• Start reviewing old homework’s so study for final.
