CONSOLIDATED October 2011 MATH (better organized)

<p>I could see it as an average curve. There were some tricky problems but it wasn’t exceptionally difficult.</p>

<p>Will the curve be harsh this year because it was easy?</p>

<p>If I omit 2 and get 4-5 wrong can I get a 700?</p>

<p>@indianguy sorry : thats probably going to be a low 600</p>

<p>@indianguy94 omitting 2 and missing 4-5 will be around a 680-690</p>

<p>Does anyone want to explain this to me?</p>

<p>Does someone have an answer for the wxyz question. I’m working it out and both of them are correct (or incorrect, as the question wanted them to be).</p>

<p>And what was the problem for this answer? 2.5 y=(k-1)^2</p>

<p>@loseyourself:</p>

<p>There was a table that looked like this:
x f(x) g(x) h(x)
0 -1 10 11</p>

<p>And the question asked for what value would f(x) + h(x) = g(x)</p>

<p>Does anyone want to give me the instructions on how to cancel a score?</p>

<p>You need to mail or fax a written, signed statement about wanting to cancel your score. Probably instructions on website.</p>

<p>The questions with 3 functions was tricky because the columns were in a different order than the equation.</p>

<p>ugh i’m pretty sure i got most/all the questions right but i bubbled in one of my math sections wrong… just my luck</p>

<p>

</p>

<p>Does anyone remember this problem? I don’t remember doing this at all! -___-</p>

<p>wait, for the f(x)+g(x)=h(x) question, wasn’t it asking ‘for how many values of x is the equation true’?</p>

<p>@Opheliaa - the question was something like:</p>

<p>If _____ biked to the library at a constant rate and took 48 minutes to get there, what fraction of the distance had she covered after 12 minutes?</p>

<p>^ Thanks! Do you remember if this was one of the first problems of the section? I definitely can’t recall doing that problem :O</p>

<p>And…I really hope not! Do you remember reading that?</p>

<p>I just answered ‘0’ because that’s when f(x)+g(x)=h(x)…but if it asked for how many values met that requirement, then…uh oh.</p>

<p>^ Yeah, same here. Yay me for reading the question!</p>

<p>It was one of the first 4 questions of its section.</p>

<p>As for the function addition one, I can’t be sure, but I have a vague feeling that that’s what the question was asking.</p>

<p>hey guys!
For the 2 circles one, was the answer D or E?
I know it was 96 pi + 64, but I’m just confused as to what the letter was.</p>

<p>Hmmm, got it! Thanks :)</p>

<p>

The answer should have been 1, then?</p>

<p>Edit: ^ The answer choice for that was E.</p>

<p>Noooo i misbubbled
screw this</p>

<p>Darn it. >_____>
Oh well, as long as I got a 2250 or above. Hahaaa.</p>
