<p>yay ! lol…i have it</p>

<p>The amazing Math II (over)prep books.</p>

<p>They help. Seriously.</p>

<p>Hi Rusen,</p>

<p>Mathematics Level 1C Subject Test, Test1</p>

<p>Question 14. If the line shown in figure 2 is the graph…</p>

<p>Ans is B: 0<ab<1</p>

<p>I don’t understand how you reach that point because a is definitely positive and b is definitely negative. I think the answer should be D.</p>

6

<p>if you go over the question once again, you will see that the equation of the line is y = ax - b therefore b is positive (this is one of the traps I placed in the question)</p>

<p>Qu 16. A quadrilateral is a rectangle if
I. it has two pairs of opposite sides that are parallel and equal in length
II. its diagonals bisect each other and are equal in length.
III. three of its exterior angles measure 90 degrees each.</p>

<p>Answer given at the back of the booklet is II or III
One of the answer choices is ‘None of the statements is sufficient’.</p>

<p>I surmise that ‘none of the statements is sufficient’ is correct, because simply saying II or III (notice that it is not just II and III, but II or III) would also imply that the shape can be a square.</p>

<p>Now, it is true that the question didn’t imply, ‘A quadrilateral is a rectangle if and only if’, but I haven’t seen the term ‘if and only if’ before in any Math subject test.</p>

<p>Question 14: Oh! That was a beautiful trap. Nice, I’ll take care of every little word in your material.</p>

<p>I guess you should have an IQ conversion table at the back, rather than just SAT conversion scores. :Smiles:</p>

<p>For instance, question 15 can be solved in almost 20 seconds by just tackling the problem from the last sentence, that is starting with 5 dollars then finally reaching 64 dollars. Initially, I used variables to represent amount spent and left - and I ended up in a lengthy expression, which was a conspicuous indication I was off track.</p>

<p>Please be aware Shailen that a square is also a rectangle. I guess you are a teacher, are you?</p>

10

<p>With all due respect, we all have to be aware of every single detail in everything.</p>

11

<p>Nice to meet a teacher here. I will send a private message to you please check back.</p>

<p>I have a question about test number 4, number 26. I don’t quite understand the explanation in the back. Can you please explain further?</p>

<p>Maths Level iC Test 6 Question 47:</p>

<p>By taking cross-sections from a right circular cone with one pane, which one(s) of the following can be obtained?
I. a triangle
II. an ellipse
III. a hyperbola</p>

<p>Answer in booklet is: III only</p>

<p>I do not agree. I believe we can get all of these shapes.</p>

<p>I: a plane parallel to the axis of the right circular cone.
II: a plane not parallel to the base of the cone
III: a plane perpendicular to the base of the cone, not passing through the apex.</p>

<p>I checked this [url='<a href="Higher Education at the Dana Center]document[/url</a>] as well. (link tested okay on 30.08.08)</p>
