MTH-095 Test Announcement! (And Practice Test 5, too)

Test 5 will be on Tuesday, December 6, in class--not in the Test Center. Don't miss class that day!

Tomorrow (12/1) will be a review for that test--check back here for the practice test, which will be done soon. Done.

The test on Tuesday will be only 16 questions at most. Open answers--no multiple choice, but you get partial credit for work that is partially correct.

Here's the practice test:

Answers to MTH-075 Practice Test #4

Here are the answers. Note that problems 11 and 16 have something wrong with them. Changes to make the problems solvable are suggested along with what those answers would be.

1. 9x³y⁷(4x⁵y² – 6x³ + 5y)

2. (x – y)(y + 4)

3. 4(x – 5)(x + 1)

4. (x + 7)(x – 9)

5. –x⁶(x³ + 9)

6. (3x² – 4y²)(5x + 6y)

7. (x + 12)(x – 8)

8. (5x + 2)(7x + 3)

9. (3x + 2y)(2x – 3y)

10. 5(2x – 1)(x + 6)

11. This one seems to be prime.

       It should probably read 21x² – 5x – 6.

        Then the answer would be (7x + 3)(3x – 2).

12. 2(7x² + 5y)(7x² – 5y)

13. (x – 7y)²

14. (5x + 9)²

15. (x² + 4)(x + 2)(x – 2)

16. As written, this problem can’t be solved by factoring.

       The problem should probably read 20x² + 31x + 18 = 6.

       Then the answer would be {–4/5, – ¾}.

17. {–5, –1/3, ¾}

18. {1/3, – 1/3}

19. {–8/21, –1)

20. {2, 5}

MTH-095 Practice Test #4 Answers

Here are the answers to the practice test. This version is in html, which has only limited support for math symbols. It's impossible to stack fractions, so instead of horizontal division bars, there are slashes. To avoid ambiguity I've added extra parentheses. Answer number 11 has a decimal where a mixed fraction would be more traditional.

1.  4x(⁴√2x)

2.  –3a³b⁸

3.  x / 2

4.  3

5.  3(⁴√x³)

6.  ³√(x + 2)²

7.  1/9

8.  x^11/12

9.  y^5/2 / x^1/4

10. 13

11. (2, 4.5)

12. –√6

13. (x² – 2)( ³√(2x))

14. 4x³(√3)

15. 3√x – x√3

16. 3 - 3√3

17. 4(√21) / 7

18. 9(³√2) / 2

19. –5(4 + √7) / 3

20. (3x – 6√(xy)) / (x – 4y)

21. x = 3

22. x = 6

23. 9i

24. 14 + 5i

25. –(6/13) + (9/13)i

Math Tutors Available!

Sharon Rogers, Associate Dean for Educational Services, informs me that there are tutors for students in developmental math (incl. MTH 075 and MTH 095) at BCC who apparently don't have enough students to keep them busy.

If you are worried about your grade, or if it bothers you that there's some homework problems you just can't do, then let me know and I'll pass your email address along, and she will see to it you get connected with a tutor.
