MATH 90 – INTERMEDIATE ALGEBRA
SUMMER 2011
Instructor: Mrs. Yolande Petersen
Office Hours: By appointment
Text: Algebra for College Students, 9th ed. by J. E. Kaufmann & K.L. Schwitters
e-mail: peterseny@mjc.edu (best way to contact – checked daily)
voice mail: 575-6500 X8256 (poor way to contact, checked weekly or less)
Web site: peterseny.faculty.mjc.edu
PREREQUISITE: Math 70 (beginning algebra) or the equivalent
HOMEWORK AND QUIZZES: Homework will be collected every day, and will include assigned
problems from all sections covered since the previous homework. Each homework assignment is worth 10
points (10 problems are randomly selected for grading). Occasional, unannounced quizzes may be given,
worth 10 pts. No late homework is allowed and no make-up quizzes will be given for any reason. However,
the lowest 3 of your homework & quiz scores will be “excused", to cover absences and forgotten homeworks.
EXAMS: There will be 5 regular exams which are graded on a straight percentage but which may be
scaled, depending on the difficulty of the exam. Exams will never be scaled downward. The scaled scores
will be assigned the grades: A = 90-100%, B = 80-89.9%, C = 70 - 79.9%, D = 60 - 69.9%. The first missed
exam will be "excused" (replaced with your final exam grade, not given a make-up). If you miss a second (or
more) exam, you may schedule a make-up; however, you must contact me by e-mail or voice mail no later
than 10 p.m. on the same day of the exam to qualify. If you do not miss any exams, your lowest exam will be
replaced with the final exam score (unless your final is lower).
GRADING: The various parts of your grade will be weighted as follows:
Homework & quizzes (with lowest 3 dropped)
Exams (with lowest 1 dropped)
Final Exam
25%
50%
25%
LEARNING OUTCOMES: Upon course completion, students will be able to solve equations and
manipulate functions involving radicals, rational expressions, quadratics, cubics, exponents, and logarithms.
Systems of 2 and 3 variables, matrices, arithmetic & geometric sequences, and combinatorics will also be
studied. Practical applications will be shown for a number areas, including home-improvement, credit cards,
retirement & college financing, mortgage interest, stock market calculations, real estate trends, and card
playing. Use of these skills in a number of professions, including medicine, law enforcement, business and
marketing, social sciences, engineering, geology/seismology, and architechture/construction will be shown.
A detailed list of the Math Dept. learning objectives met is available on my website at the Math 90 link.

MATH 90 HOMEWORK ASSIGNMENTS – SUMMER 2011
All sections covered in a given class will be collected the next class as one assignment. Assignments which
are not stapled or paper-clipped into a single packet (may be several sections) will receive a 1 point
deduction. Work for more difficult problems must be shown to receive full credit.
 Where ellipses (…) are used, do the multiples of 3 in between. Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24,
27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99
 A dash means all numbers between and including the listed numbers, (1 – 6 means 1, 2, 3, 4, 5, 6)
 Quick Review sections have homework from Review Exercises at the end of the chapter. Sections
covered in depth have homework taken from the end of section.

Classroom Guidelines
1. The learning of the whole class comes first.
Questions directed to the instructor so the whole class can hear are welcome. However, any talking while
the instructor is talking is very distracting (even talking about math). Cell phones, including texting, are also
distracting. Those who repeatedly engage in disruptive behavior will be given a written warning, then
dismissed in accordance with MJC's Student Code of Conduct (see mjc.edu). All electronic devices (except
approved calculators) should be silent and stored away out of sight. Approved calculators include those that
have no communication ability and no mass storage for photos or data. For example, cell phones, laptops,
or i-pads may not be used as calculators.
2. Every class period is important.
You are responsible for all material covered and all announcements made in class, even if you are absent. "I
didn't know because I wasn't there" is not a valid excuse for missing tests, homework assignments, or extra
credit opportunities.
3. The syllabus is the final word on your grade and other administrative issues.
The syllabus provides flexibility for emergencies such as illness, car trouble, accidentally leaving homework
at home, etc. by allowing excused homework/quizzes and one excused exam. However, do not expect
exceptions to be made from the syllabus policies.
4. The student is expected to take the initiative in completing course requirements.
The instructor will not call you if you miss tests or are absent. However, if are absent for 5 or more class
periods, you should contact the instructor to verify your status in the class. Missing 5 or more classes may
possibly (but not necessarily) result in your being dropped. Documentation (jury duty, medical verification)
must be provided if you need to be excused for more than the allotted excused homeworks/quizzes and
exam. If you are not satisfied with your progress in the class, you must drop yourself – the instructor may or
may not drop you.
5. Cheating will not be tolerated.
Outside assistance (written materials, tutors) is permitted for homework. However, use of any materials
beyond what is explicitly permitted during exams constitutes cheating. This includes any books or notes
beyond the allowed card(s), as well as additional informational resources from inside or outside the
classroom. Any incidence of cheating will result in an automatic zero for that test or assignment, and that
score cannot count as an "excused" score. Cell phones and/or any electronic devices beyond approved
calculators, including music players, may not be used for any reason during tests. (Be sure you have a noncommunicating calculator).
(do not tear off – this form will be provided in class)
----------------------------------------------------------------------------------------------------------I understand and agree to accept the consequences of the points outlined above and in the syllabus. In
particular, I understand that engaging in private conversation and use of electronic devices (including texting)
is unacceptable classroom behavior.
