1 MATH 20 Intermediate Algebra Course Syllabus Fall Session, 2011 Instructor: Brian Rodas Class Room and Time: MC 10 M-Th 12:45pm-1:50pm Office Room: MC 35 Office Phone: (310) Office Hours: M 2:30-3:30pm, TTh 2-3pm and W 2:30-3:30pm(Math Study Room MC 84) and by appointment rodas Class Website: brian Text: Intermediate Algebra, 6th ed., Dugopolski, McGraw Hill, 2009 Supplemental Text: Santa Monica College, Math 20 Supplement Package, 2010 Course Description: This course is an intensive 5-credit course intended for students who need to take Math 26, Math 2 or Math 41. Topics to be covered include but are not limited to fundamental operations on algebraic expressions and functions, equations and inequalities in one variable, rational numbers and functions, irrational numbers, complex numbers, quadratic equations and functions, exponential and logarithmic functions, linear and nonlinear systems, matrices and graphing. Emphasis is on advanced factoring and simplification. The prerequisite for this course is Math 31. Format of Course: The first 5 minutes of each class will be devoted to addressing students questions regarding homework or material from the previous section. The remainder of the class will be spent presenting new material. Homework: Homework will be assigned daily, collected and graded. The problems assigned are practice problems in understanding the material covered for the day. It has been known that a genuine understanding and completion of the homework results in quality performance. Quizzes: Quizzes will be given periodically. They will be approximately 10 minutes long. It has been my nature to give quiz problems identical to the homework. Therefore it would be in your best interest to do the homework. Each quiz is worth ten points. The two lowest quiz scores will be dropped. Exams: There will be five exams and a final. Exams will contain material from the chapter(s) and supplements covered. Each exam is worth 100 points. The lowest exam will be scaled out of 50 points. So if your test scores are 100, 90, 80, 70, and 60 then your test average is ( )/450. The final is worth 200 points and is cumulative. You must show all necessary work on all submitted material including homework, quizzes and exams to receive full credit. Calculators: A calculator is nice to have for this course but is not required. It can be used for tedious exercises, checking answers and explorations but generally is not allowed for quizzes and exams. Grading: Top four exams Lowest exam Quizzes Homework Final exam Total 400 points 50 points 75 points 75 points 200 points 800 points The expectation is that a letter grade will be given using the following scale for the semester average: %(A), 80-89%(B), 70-79%(C), 60-69%(D), 0-59%(F).

2 Academic Conduct: You are expected to abide by Santa Monica College s code of student conduct and academic conduct on all exams, quizzes and homework. Copying homework solutions or quiz or test answers from someone is considered cheating as is altering a quiz or examination after it has been graded or giving answers to someone during an exam or quiz. If caught cheating or using an electronic device during an exam, the parties involved will receive a zero on the exam and an academic dishonesty report will be filed. Also note that cell phones are to be turned off for the duration of each class. Since attendance is essential for normal progress in class, a student is expected to be in class regularly and on time. Missing classes puts you in danger of being dropped. There are no makeup assignments, quizzes or exams. Late assignments will not be accepted. No excuses. Refer to the school s web page, for withdrawal dates. Note that the last day to withdraw with a guaranteed W is 10pm October 23, 2011 by phone/web. IT IS THE STUDENT S RESPONSIBILITY TO BE AWARE OF WITHDRAWAL DATES AND TO TAKE THE APPROPRIATE NECESSARY STEPS. If a student does not withdraw and stops coming to class, the student will receive a failing grade. Learning Mathematics: Learning mathematics takes time and consistent effort. Attending class regularly, completing all assignments and reading class notes are essential for success in this course for most students. Students in need of additional assistance should be encouraged to make use of the Math Lab where instructional assistants, tutors and mathematical tutoring software are available. The lab is open Monday-Thursday 8am-10pm and Friday 8am-4pm. Forming study groups outside of class may also offer further support. Entry Skills for Math 20: Prior to enrolling in Math 20 students should be able to: A. Simplify and perform basic operations on rational expressions. B. Perform basic operations on polynomials. C. Factor general trinomials at an elementary level. D. Solve linear equations in a single variable over the rationals. E. Solve second degree polynomial equations in a single variable over the rationals by factoring. F. Simplify square roots. G. Solve first degree linear inequalities in a single variable. H. Solve applications involving equations in a single variable. I. Solve linear systems of two equations in two variables. J. Graph first degree equations/inequalities in one and two variables. Exit skills for MATH 20: Upon successful completion of this course, the student will be able to: A. Simplify advanced numerical and algebraic expressions involving multiple operations. B. Solve linear, quadratic, rational and absolute value inequalities, graph their solution sets, and express the answer in interval notation. C. Solve literal equations for a designated variable. D. Apply algorithms of completing the square, rationalizing the denominator, and long division and synthetic division of polynomials. E. Solve linear, quadratic form, simple cubic, radical, rational, absolute value, elementary exponential, and elementary logarithmic equations. F. Solve systems of linear equations in three variables using matrix row reduction. G. Graph the solution sets of systems of linear and quadratic inequalities. H. Perform operations on complex numbers. I. Perform operations on functions including composition of two functions and determine the domain of the resulting function. J.Use proper mathematical notation to evaluate functions and obtain their inverses. K. State and apply the fundamental properties of exponents and logarithms. L. Demonstrate knowledge of standard vocabulary associated with graphing, including but not limited to slopes of lines, intercepts, vertex of parabola, asymptotes, and interplay between graph and functional notation. M. Given its graph, determine whether a relation is a function and whether it is one-to-one, and determine its intercepts and domain and range. N. Graph using horizontal and vertical translations and determine the domain and range of linear, quadratic, simple cubic, radical, reciprocal, absolute value, exponential and logarithmic functions. O. Graph circles and parabolas using horizontal and vertical translation. P. Evaluate simple expressions involving summation notation. Q. Set up and solve practical applications of the algebraic material.
