MT - Major Test..... Will take the entire class period. WS - Worksheet | ||
| Mon. | Jan 14 | Ch1R, T1, T1R (See Syllabus for page & problem numbers.); WS#1; print out Syllabus.
Get familiar with this web page. Read and/or print out any other things you will need such as Study Tips, Semester Calendar, Skills Tests Info, and Skills Tests List. Also print out WS#2 (If it is not available now, it should be by late Tuesday,) and bring to class on Wed. If you have problems with the web page, please let me know. Mon. night update: WS#2 has been uploaded. |
| Wed. | Jan 16 | WS#2
IMPORTANT ANNOUNCEMENT: The University computer system Banner is supposed to check your records for pre-requisites before allowing you to register for a class; however, it apparently is not working properly and some have been allowed to register for this coure without proper pre-requisites. We will get them checked by hand eventually; however, I am sure that you don't want to be removed from the class when it is too late to add something else. Please make sure that you meet one of the following requirements: Made a C or higher in LS098 Have a test score, no more than 3 years old: ACT - 17 or higher (in math) SAT - 400 or higher (in math) Have taken the math placement test and told that you qualify for MS 100. NEW WEB PAGE FEATURE: I will be making SOME EVEN ANSWERS from the book available during the semester. I decided that they would be easier to access through a separate link, so you will notice a separate "box" next to Work Sheets. These will be posted as needed when an "All" assignment is made from the book or as possible when requested for other book assignments. Of course, all worksheets have the even answers included. |
| Mon. | Jan 21 | No Classes |
| Wed. | Jan 23 | WS#3 (Covers 3.1 and part of 3.3); WS#4 (Covers part of 3.3); WS#5
(Covers all of 3.3)
I would consider that WS#3 and #5 are necessary. You may use your judgment as to whether you feel that WS#4 is needed for you. However, before you decide that it is not necessary, ask yourself: "Am I REALLY GOOD at FOIL?" This would indicate that you are VERY comfortable with combining the Outer & Inner terms MENTALLY & QUICKLY to get the Middle term obtained in the typical FOIL product. Make sure you understand these combinations in problems such as #32, 48 & 77 where there are 2 variables or higher powers involved. Also make sure you understand and will quickly remember that binomials squared such as #9, 41 & 45 must be thought of in terms of FOIL or remembering the pattern of a binomial squared. As with any assignment, you may use the exercises in the book for further practice. |
| Mon. | Jan 28 | WS#6 (Covers 3.2 & 5.1)
This worksheet is being uploaded at the same time as this assignment, so you should be able to find it now. COMMENTS ON WS#6: For a reminder of basic Exponent Rules, see pages 225 - 227 in the various shaded boxes. WS#6 will give you good practice in applying these rules. You might want to get notes from someone in class for further helpful hints if you missed class. My basic HINT was: Apply these rules regardless of whether the exponents are whole numbers, negative numbers, fractions, radicals or variables. We briefly discussed the meaning of fractional exponents; but 59, 63, 82, 86, & 96 are the only problems where you need to know what the fractional exponent means. In other cases, the problem can be worked by applying the exponent rules you already know. SEE DATE FOR MAJOR TEST #1 TO BE GIVEN IN 355 AYERS NEW WEB PAGE FEATURE: In the same page as the even numbered answers, I will post the problems that need correction on any of the worksheets. When corrected versions of the worksheet are posted, the link page will indicate that the worksheet has been corrected. |
| Wed. | Jan 30 | WS#7 (Do problems 1 - 21... We will come back to the last ones later.)
2.1B (2.1: All of #51 - 56); 2.2B (2.2: 41, 42, 45) Even answers to these are posted. Previous assignment that I STRONGLY RECOMMEND reviewing is p.38, #64-99 and p. 42, #43-60. These exercises will help you to get oriented to the proper "translation techniques" to use in going from an English phrase or sentence to the corresponding Algebraic expression or equation. We did the evens on p. 38 in class today. NOTE on WS#7: These are the simplest kinds of word problems where there is basically only one unknown number that we are looking for. To help you in your learning process and since I REQUIRE that every word problem on the test have the proper algebraic expression or equation set up, the answers on the worksheet include the correct equation that needs to be solved. Like checking any other answer, you will not get as much benefit if you "cheat" and look at the answer before you have tried your best to work the problem yourself. |
| Mon. | Feb 4 | 7.1 with Extra Instructions as follows: For the first ten problems, I am
giving you below an x-value and a y-value to use. Find the corresponding
points of the line and graph using these two points. (The correct ordered pairs
are given on this web page under Even Answers.) For the remainder of the
problems (#11-33), find the x-intercept and the y-intercept. If this yields
only one point, then you will obviously have to find another point using an alternate
method. You may pick an arbitrary x or y-value and find the corresponding y or x-value
to find another ordered pair. Using the 2 or 3 (good as a check on
yourself) points you have found, draw the correct line. The odd problems have
the correct graph in the back of the book so that you can check yourself on those.
Note: The graphs for #1 - 10 will not specifically indicate the points that you
found; however, you should be able to tell if your graph agrees with the book's
answer. On the test you MUST
USE A STRAIGHT EDGE and draw a neat line that extends across the entire graph
provided.
VALUES TO BE USED FOR #1 - 10: #1. x = 10, y = 4 #2. x = -1, y = 12 #3. x = 5, y = -3 #4. x = -2, y = 6 #5. x = 4, y = -6 #6. x = -3, y = -6 #7. x = 2, y = -10 #8. x = 3, y = -2 #9. x = 6, y = -5 #10. x = -2, y = -12 MAJOR TEST #1 REMINDER (See Below) Be Ready to Ask Questions on Wed. There will probably be a very brief lecture on new material; however, anything covered on Wed. will NOT be on the 1st test. Most of the class will be left for YOU to ask questions over test material. I do not give out practice tests or study guides for regular tests. (See Study Tips under Course Info for help on studying.) Consequently, you need to come prepared to ask questions. I can not "re-teach" everything we have done so far. |
| Wed. | Feb 6 | WS#8 covering exact radical problems will NOT be on this test, but
we covered the ideas in class so that you can work on this WS after
the test. Be ready with questions over this material on Wed. 2/13.
This worksheet has been uploaded and there is one correction to an answer
on WS#7. (It was the answer to #23, which I had not yet assigned.
The given equation was correct, but the final answer should be -7/2.)
REMEMBER TEST ON MON IN ROOM 355. I will arrive early, and you may start early and leave when you are through. HIGHLIGHTED SYLLABUS HAS BEEN UPLOADED. This shows the sections and worksheets covered on this test. |
| Mon. | Feb 11 | MAJOR TEST #1 TO BE GIVEN IN 355 AYERS
REMEMBER to work on WS#8 and be ready to ask questions on Wed. 2/13. |
| Wed. | Feb 13 | 2.5A & B; WS#9 (Remember to change the number on the WS... It says #17, but
it is our #9.)
We learned a new notation for inequality solutions. It is called Interval Notation and can be thought of as a "short-hand" Number Line. Remember that when solving inequalities, we can work in the same basic pattern as solving equations; BUT you keep the inequality symbol instead of =, and it will stay in the same direction for all operations EXCEPT MULTIPLICATION OR DIVISION BY A NEGATIVE REVERSES THE DIRECTION OF THE INEQUALITY! WS#9 is to be used in conjunction with 7.1 in the book. I know that we have already "done" 7.1, but we are now using these same problems to come back and approach lines from a different view. This WS will give you practice in putting equations of lines into slope-intercept form, and interpreting what the slope and y-intercept are from this form. In addition, we learned today that perpendicular lines have slopes that are negative reciprocals of one another. The WS will give you practice with this fact, and also some additional practice with finding x-intercepts. I suggest that you try to find the x-intercept from the slope-intercept form, so that you have practice from that direction also. (Probably most of the problems that you did in 7.1 before started with the equation in standard form.) So, the WS is in fact the answers to 5 different questions about each problem in 7.1. You may choose to do only the odds, or the evens also for extra practice. Try graphing by using the y-intercept as a starting point and using slope as rise over run to count up and over or down and over to the "next point." Remember that UP and RIGHT are POSITIVE moves and DOWN and LEFT are negative moves, so make sure that the sign works out properly for the slope. Lines with positive slope go "up" when looking left to right, while lines with negative slope go "down" when looking left to right. Of course, check the graphs in the back of the book for the odd problems. |
| Mon. | Feb 18 | WS#10 (Has already been uploaded.)
This worksheet will cover the basics of factoring, including GCF (Greatest Common Factor), Difference of Squares, and FOIL Factor (or Trinomial Factor). In particular the FOIL Factor problems in this worksheet are very basic, so we will come back to more difficult examples later. NOTE: Important factoring tip to remember is ALWAYS check for GCF FIRST! Doing this is sometimes the only factoring pattern that will work, and even if another pattern will work, doing this FIRST will make other steps easier. Of course, there is not always a common factor, so apply other patterns as needed. ALSO remember that when there is a common factor, there will be the same number of terms inside the parentheses that there were in the original expression. |
| Wed. | Feb 20 | WS#11; 3.4B (p.135: #47-64); 3.5B (p. 142: #45-56)
WS#12 is uploaded for you to use for extra practice for problems like those in 2.5. |
| Mon. | Feb 25 | WS#13 (General Factoring Review); WS#14 (Rational Simplification, including
Products and Quotients.)
Since I did not get these uploaded til about 10:30 PM Mon, at least try to do a sampling from WS#14 before class on Wed. to make sure that you are understanding this procedure. We will be doing more Word Problems on Wed. as the last new material before the test. See Test Date Below |
| Wed. | Feb 27 | Finish WS#13 & #14. Go back and Finish WS#7 (Word Problems - #22-25);
2.1C (#57-66); 2.2C (#48-54);
2.2D (#43, 44, 47; 55-58); 2.4D (#47, 48); Ch2R (p. 104: #45, 47, 48, 51)
NOTE: For the word problems in the book, you should do the even problems also. I have posted the even answers on my web page. We are mostly setting these up in terms of 2 equations with 2 unknowns and using the method of substitution for solving the 2 equations. This is indicated in the worksheet answers and in the even answers I have posted on the web page. NOTICE TEST DATE BELOW! |
| Mon. | Mar 3 | LAST DAY TO BEGIN SKILLS TESTS
ASSIGNMENT - NOT ON THIS TEST!: WS#15... Do the first page. Be ready with questions on Mon, 3/10 TEST ON WED IN ROOM 355! |
| Wed. | Mar 5 | MAJOR TEST #2 TO BE GIVEN IN 355 AYERS |
| Thur. | Mar 6 | This a Thursday. No class.
Midterm Your midterm grade is determined by the first test grade, since I will not have the 2nd test graded in time. If your grade on Test #1 was below 70 or if you did not take the first test, you will be assigned an NC at midterm. This does not go on your permanent record, and does not mean that you can not pass this course. It does indicate, obviously, that you have work to do. |
| Mon. | Mar 10 | LAST DAY TO DROP WITHOUT PENALTY. (NO SIGNATURE NEEDED)
Finish WS#15 thru #38; WS#16 See Announcement about the change in my schedule for Tutoring. NOTE on WS#16: We will be using the following 3 step process for solving non-linear equations by factoring. 1. Get the equation set = 0 and in simplified form. 2. Factor Completely 3. Set each Factor = 0 and solve. (This is using the fact that the only way that a product can be 0 is for one of the factors to equal 0.) CAUTION: Pay attention to which step the problem is when it is given. You may have to set = 0 and simplify and proceed; you may already be set = 0 and simplified so that you are ready to factor; or you may already be set = 0 and in factored form (at the end of Step 2 and ready for Step 3.) |
| Wed. | Mar 12 | 7.3; Finish WS#15 & WS#16
NOTE: For the "shade graphs" in 7.3: 1. Graph the "Boundary Line", that is use "=" instead of the inequality to see what the "Boundary" of this big area will be. 2. If the inequality is strictly < or >, then make the boundary line dotted or dashed because it is not included. If it is "or equal to", then make the boundary line solid because it is included. 3. Find a point (an ordered pair) that is clearly NOT on the Boundary Line. 4. TEST this point in the ORIGINAL inequality. (Substitute the x-coordinate for x, and the y-coordinate for y.) 5. IF the resulting is a TRUE statement, then that point and all other points on the same side of the line satisfy the inequality, so you SHADE THAT SIDE. 6. IF the resulting statement is a FALSE statement, then that point and all other points on that side of the line do NOT satisfy the inequality, so you SHADE THE OTHER SIDE OF THE LINE. COMPOUND INEQUALITIES: For statements of "and", you must graph each solution set and then find where the solution sets intersect or overlap. That will be the final solution. |

NOTE on homework: I may post some hints for those that were not in class, but it will be later today or Tuesday. |
| Wed. | Apr 2 | WS#20
NOTE on WS#20: There was one kind of problem that I forgot to explain to you: The ones that involve rationalizing a binomial (2 term) denominator. The basic idea in working these is to use the way that the difference of squares factors. (Because of limited algebraic capabilities here, I will use the "^" symbol to indicate something is raised to a power, the same way that many of your calculators do. For example: x^2 means "x squared.") Remember that A^2 - B^2 = (A - B)(A + B). If we have a binomial denominator that has a square root in one or both terms, we can use this fact to create a new expression that squares each term, but does not create another radical (as we saw happen today with the binomial radical expression that we squared.) So, if the denominator looks like (A - B), (where A and/or B contains a radical), we need to multiply it by (A + B) to obtain A^2 - B^2. The square roots contained in A and/or B will thus be "removed." In similar fashion if the denominator looks like (A + B), (where A and/or B contains a radical), we need to multiply it by (A - B) to obtain A^2 - B^2. The square roots contained in A and/or B will again be "removed." Obviously to keep equality to the original expression, we must multiply the numerator by the same as what we multiplied by the denominator, so that we have only mulitplied by ONE. See Examples 4 & 5 on page 253 in your book to clarify this explanation. REMEMBER TEST DATE BELOW |
