Two evaluation surveys –Please take time to do both!

You should have received two separate survey email requests:

  • One was from Professor Foley (via Pearson) – This one is an evaluation of the Math 010/110 Teaching and Learning Center structure. This will help us evaluate our course setup, software, tutor lab, TAs, and online grading/assignments/learning aids.
  • The other was from Dr. Chris Bendel, MSCS dept. chair-- This one is an evaluation of the teacher of your Math 010 or 110 class section.This will give feedback to the department and to your own teacher about how you rate the effectiveness of instruction in your particular class section.

Your feedback on both of these surveys will be very helpful to us in evaluating and improving our teaching methods and the Math TLC program – THANK YOU!!!

Your feedback on both of this survey will be very helpful to us in evaluating and improving the Math TLC program. THANK YOU!!!

final exam review assignments

Final Exam Review Assignments:

Four review homework assignments: These are each worth 15 points, vs. the usual homework assignment of 4 points.

Unit 1 review homework (Chapters 1, 2, 3).

Due last Thursday.

Unit 2 review homework (Chapters 4, 5, 8):

Due today.(If you need an extension on either the Unit 1 or 2 Review, see or email me TODAY so you can finish it and get access to the Unit 3 review HW.)

Unit 3 review homework (Chapter 6):

NOTE: You must get at least 80% on the Unit 2 Review before you can start the Unit 3 review. Due at the start of class tomorrow (Tuesday, May 7)

Unit 4 review homework (Chapter 7):

NOTE: You must get at least 80% on the Unit 3 Review before you can start the Unit 4 review. Due at the 8:00 p.mon Study Day (Wed., May 8)

math 110 final exam
Math 110 Final Exam:
  • Comprehensive, worth 200 points (20% of course grade)
  • The practice final has 47 questions, as does the regular final exam. The questions will NOT be exactly the same as those on the regular final, but they will be similar in content and are distributed across sections the same way as on the regular final.
  • Each time you take the practice final you will get a different set of questions, AND your highest score will earn you that percentage of 20 extra credit points on the final, so it will pay off if you can find the time to take it more than once.
  • IMPORTANT NOTE!!!To get access to the practice final, you must have submitted all four final exam review homework assignments and have scored at least 80% on each one.

final exam review unit 3

Final Exam Review, Unit 3

Unit 3 Covers:Chapter 6 (Rational expressions)

slide10
Don’t forget to review the application problems from section 6.6 homework and your work on the offline worksheet.

(Remember those fun problems about planes and cars, and three people doing a job at different rates?)

These were a common source of trouble for many students in previous semesters, so make sure you study the application problems on the Practice Test, and then review the section 6.6 homework if you need more work on those problems.

Unit 3:Chapter 6 (Rational Expressions)

important
IMPORTANT:

Almost all problems in Chapter 6 on rational expressions require you to use one or more techniques for factoring polynomials.

DON’T FORGET TO REVIEW THESE FACTORING METHODS AND KNOW HOW AND WHEN TO USE EACH ONE!

Two methods that students often have trouble with are factoring by grouping and sums/differences of cubes, so make sure you review problems using these methods.

domain example
Domain example:

Find the domain of the expression

Solution: Set the denominator equal to zero and solve for x. (Notice that this boils down to a factoring problem.)

x2 – x – 20 = 0

(x – 5)(x + 4) = 0

(x – 5) = 0 gives x = 5,

and (x + 4) = 0 gives x = -4

Therefore the domain is {x | x ≠ 5 and x ≠ -4}

slide13

Example

Multiply the following rational expressions.

Solution: Factor each polynomial completely,

then cancel all factors that appear on both the top

and the bottom.

NOTE: This problem uses factoring by grouping, factoring out a GCF (twice!), and the sum of cubes formula.

Whew!

slide14

Example

Add the following rational expressions.

slide15

Example

Dividing a polynomial by a monomial:

Divide each term of the polynomial separately by the monomial.

slide16

Example

-

35

x

-

15

Dividing a trinomial by a binomial:

Divide 7x into 28x2.

Multiply 4x times 7x+3.

Subtract 28x2 + 12x from 28x2 – 23x.

Bring down -15.

Divide 7x into –35x.

Multiply -5 times 7x+3.

Subtract –35x–15 from –35x–15.

Nothing to bring down.

So our answer is 4x – 5.

HOW WOULD YOU CHECK THIS ANSWER???

slide17
Example of a complex fraction:

10

3x .

5

6x

Solution: view as a division problem:

10÷ 5 = 10 · 6x = 4

3x 6x 3x 5

example solving a rational equation
Example: Solving a rational equation:

Solve 2x + 1 = 1 .

2x – 1 x 2x – 1

Solution:

1. Multiply both sides by the LCD x(2x – 1).

This gives 2x(x) + 1(2x – 1) = 1(x)

2. Now simplify this equation:

2x2 + 2x – 1 = x

2x2 + x – 1 = 0

3. Solve either by factoring or by using the quadratic formula.

Answers: x = -1, x = 1/2

example continued
Example (continued):

NOW CHECKBOTH ANSWERS in original equation:

Note that when you plug in x = -1, everything checks out OK ( you get -1/3 = -1/3)

BUT when you plug in x = 1/2, you get zeroes in some denominators, so this number is NOT a solution. (it gives 1 + 1 = 1

0 ½ 0

So the final answer is just x = -1

(if you write x = -1, 1/2, you’ll get ZERO credit.)

slide20

REMINDER: Comprehensive Practice Final:

Once you finish the Unit 3 and 4 Final Review homework assignments with at least an 80% score, you will have access to the practice final, with as many attempts as you want.

The practice final is worth 10 points, plus a possible bonus of up to 20 extra credit points on the final exam. Your best percentage score on the practice final will earn that percent of 10 points toward your course grade, plus that best score percent times 20 extra credit points will be added on to your final exam point score before partial credit points are added.

This makes it extremely important for you to make sure you work to get at least 80% on each of the four final exam review homework assignments so that you can get access to the practice final.
