Type of Examination: Closed text, open notes. Do your own work. Do not help your classmates. Do not even discuss the examinations with one another until after all of you have mailed your answer-sheets to Mr. Heath. Please report any infractions to our Honor Code to Mr. Heath or Mr. Jones! If you have any difficulty with the examination, check your notebook. Your text is not to be used and would be of little help anyway! If you have not done so already, this examination will help you learn to take and use excellent notes!

- Part 1 is due in two weeks, i.e., 18 May 2006
- Part 2, to be provided before 05 May 2006 will be due a fortnight {two weeks} after it is posted on the PACE website.

Complete your examination and mail it to your Lead Instructor at the following address:

Mr. Ernest Alfred Heath Jr.

PACE Algebra 2 Lead Instructor

Pleasure Bay Drive, No. 242

Long Branch, NJ 07740

If you have not handed in your algebra 2 book, send the instructor a letter explaining how you propose to return it, or bring it to the Monmouth County Cotillion {Scholarship Debutante Ball} <06 May '06> or the PACE Banquet <13 May '06>.

Solve the following problems. Each problem is worth 10 points. No partial credit
will be given.

Recommendation: first try timing yourself. Then go over your initial answers carefully to determine where you need further study. Try to complete every problem. You have to score 100% of the normal question to have the opportunity to receive extra credit, so do not waste your time on the extra credit problems unless you have already answered all of the others correctly!

Check your work, check it again, then check it again!

0. 8^{4}^{x}^{-1} = 6^{1-}* ^{x}*, solve for

1. *x*^{6} + 2*x*^{3} + 2 = 0

2. 2*x*^{8} - 4*x*^{4} + 5 = 0

3. 3 + 2/*x*^{2} - 4/*x*^{4} = 0

4. 12*x*^{2} - 5*x* - 7 > 0

5. 2*x*^{2} - 9*x* - 5 < 0

6. *x*^{3} -5x^{2} - 6*x* > 0

7. Solve the linear system of equations

= (≥) 3

1*x* + 1*y* - 1*z* = (≥) 1

-1*z* + 1*y* + 1*z* = (≤) 7

9. Solve the linear system of equations (inequalities for extra credit)

1/*x* + 1/*y* + 0/*z*
= (≤) 5/2

0/*x* + 1/*y* + 1/*z* = (≥) 3

1/*x* + 0/*y* + 1/*z* = (≤) 3/2

10. Solve for *x*:

12* ^{u}* = 9

Good Luck!

It was an honor to be your Algebra 2 Instructor,

0. 4x^{8} - 4x^{4} + 5 = 0

1. | 1x^{4} + 11x^{2} + 2 | <= 5

2. | 3x^{6} + 18x^{3} + 2 | <= 5

3. | 3x^{2} + 20x + 2| > 4

4. Find the solution set for this simple system of two simultaneous quadratic inequalities:

3x^{2} + 16x + 1 <= 10

1x^{2} + 10x + 2 >= 05

3. Find the solution set for this simple system of two simultaneous cubic inequalities:

x^{3} - 15 >= 12

x^{3} + 14 <= -50

4. Find the solution set for this simple system of simultaneous quadric and hexic
inequalities:

x^{4} - x^{2} - 1 <= +1

x^{6} + x^{3} - 1 >= +1

5. Solve this simple system of four simultaneous linear equations in four unknowns

+1x - 3y + 5z - 7t = +1

+3x + 2y + 7z + 4t = +4

+5x - 7y - 1z - 2t = +3

+7x - 4y - 2z + 2t = +2

6. Solve this simple system of two trigonometric linear equations for the angle A,
or the sin(A) or the cos(A). {Please note: if x0 = sin(A0) then A0 = Sin^{-1}(x0)
= Arcsin(x0), and similarly, if if y0 = cos(A0) then A0 = Cos^{-1}(x0) =
Arccos(x0)} [Hint: Avoid distractions}

TVcos(A) + (MAL^{2})sin(A) = U-PROB-FAIL

(DRINK)cos(A) + (DRUGS)sin(A) = exp(U-DEF-FAIL),

Where TV, MAL2, U-PROB-FAIL, DRINK, DRUGS, U-DEF-FAIL are all real constants. [Hint:
substitute simple letters for TV, MAL2, U-PROB-FAIL, DRINK, DRUGS, and exp(U-DEF-FAIL);
say a, b, c, d, e, and f; solve the system and then use your answers to substitute
back to get your final answer. Perhaps you can use this to show your younger brothers,
sisters, and friends how algebra and trigonometry can work together.

7. Divide (9x^{8} + 7x^{6} + 4x^{4} + 2x^{2} + 1)

c. x_{2} - x + 1

8. Divide (4^{6} + 12x^{5} + 6x^{4} + 3x^{3} + 2x^{2}
