Course Description: This course includes applications of algebra, linear algebra, and probability to the areas of business and the social sciences. Access to a departmentally approved graphing calculator is required. (We recommend the TI-83 or TI-84.) Prerequisite: Math ACT score of at least 20 or consent of the department.

Course Objectives: Upon successful completion of this course, the student should be able to:

· understand the concept of a function

· solve linear equations, quadratic equations and systems of linear equations

· use linear, quadratic, logarithmic, and exponential functions to solve business and economic problems

· perform matrix operations and use matrices to solve systems of equations and various applications

· solve inequalities and use inequalities in various application problems

· compute simple and compound interest

· solve problems involving annuities, loans and amortization

Assigned Text:

Finite Mathematics and Calculus with Applications (9th ed.) by Lial, Greenwall, and Ritchey

Students are required to purchases a MyMathLab student access kit (ISBN 9780321199911). This will provide the student with an electronic version of the textbook. Students who plan to purchase both the physical textbook and the MyMathLab access kit should purchase the combination package (ISBN 9780321760043).

Attendance: The ETBU attendance policy states the student must attend at least 75 percent all class meetings. This translates into allowing a maximum of seven absences in a class that meets twice a week. Eight or more absences will result in an automatic grade of F for the course.

Students are expected to arrive on time and stay until class is dismissed in order to be counted as present. If a student is sleeping or engaging in disruptive behavior he will be asked to leave the room and will be marked absent. Cell phones, laptop computers and other electronic devices should not be used during class time.

Examinations and Grading Policy: The course grade will be determined by averaging the grades from three unit tests (each accounting for 20% of the grade), homework (15%), and a comprehensive final (accounting for 25% of the grade). The grade on the final exam will replace your lowest test score if it helps you. Optional online quizzes can also earn extra credit (up to 5%) on each exam.

The semester grade will be based upon the following scale:

A 90%-100%

B 80%-89%

C 70%-79%

D 60%-69%

F below 60%

Academic Integrity: Students enrolled at ETBU are expected to conduct themselves in accordance with the highest standards of academic honesty and integrity avoiding all forms of cheating, illicit possession of examinations or examination materials, unwarranted access to instructor’s solutions’ manuals, plagiarism, forgery, collusion and submissions of the same assignment to multiple courses. If you are caught cheating on an assignment or exam you will receive a score of 0 on that assignment or exam. All incidents related to violations of academic integrity are required to be reported to the Vice President for Academic Affairs and multiple violations of academic integrity will result in further disciplinary measures which could lead to dismissal from the University.

Makeup Policy: Make-up tests will be allowed only in the event of compelling reasons such as illness, a death in the immediate family, or a university-approved absence. It is the student’s responsibility to contact the instructor as soon as possible to discuss the possibility of a make-up test. This should be done before the regularly scheduled test time.

Disability Accommodation: Students with a disability may request appropriate accommodations for this course by contacting the Office of Academic Success located in Marshall Hall, Room 301, and providing the required documentation. If accommodations are approved by the Disability Accommodations Committee, the Academic Success and Graduate Services will notify you and your professor of the approved accommodations. You must then discuss these accommodations with your professor.

All proctored exams for students with accommodations will be given in the library. The five individual testing rooms are equipped for recording video and audio, so the student can be monitored by the testing coordinator and faculty can review video for up to 48 hours after test is given. Tests should be delivered to the testing coordinator two class days prior to the test date. It is the student’s responsibility to schedule the test date one week prior to the test and time using the ACE website (www.etbu.edu/ace). Ideally, exams will be given the same day as the course schedule.

Homework: Homework will be submitted electronically through my MyMathLab. When you enter the Assignments area on Blackboard, you will see a link in Support Tools called Student Help. Click on this and then choose the Blackboard icon. This will lead you to instruction on how to enter the access code found in your MyMathLab access kit. Once you have registered your access code you will be able to go the Assignments area in Blackboard to access homework assignments.

There is at least one homework assignment for each section of the text that we will cover this semester. For most assignments the online homework system will provide you with many help buttons such as “Help Me Solve This”, “Ask My Instructor”, and similar exercises. In some sections you will have two assignments – one with the help buttons and one without. Homework will be due at class time on the class day after a section was completed. Late homework will receive a 30% deduction. No late homework will be accepted after you have been tested on a section of material. There will also be several bonus review assignments that you can do to improve your homework grade.

Academic Center for Excellence: The Academic Center for Excellence (ACE), located in the library, is intended to provide a place for individual and small group study. Also, computers are available for student use. Mathematics tutors will be on duty at times to be announced. Extra credit will be given for utilizing the MLC when a tutor is on duty. When you work on your mathematics course in the MLC for at least 30 minutes you will be issued a coupon by the tutor on duty. Only one coupon may be earned each day. Each coupon that you return to your instructor will increase your homework average by .5%. The maximum number of coupons you can earn during the semester is 10. Therefore, you can increase your homework average up to 5% by utilizing the tutors in the MLC.

Tentative Course Outline: Due dates for individual assignments will be posted on the MyMathLab website.
