November 2010 MATH 2 Discussion Thread

<p>yea perfect its -ab and then it comes out to 11</p>

<p>Righto. So I’m back to two wrong.</p>

<p>And you guys can call me pixie. That’s the second part of my name. I’m no perfect creature.</p>

<p>TheMathNerd- perfect pixie is using a completely different method than physics vector addition. law of cosines in essence</p>

<p>6.23 was an answer, doesnt it just create a triangle with sides of 4 and 8 and u need to find the third side which was 6.23 no?</p>

<p>idk i hatetesttaking im pretty sure it was 11</p>

<p>would you guys consider this easy/medium/hard? im trying to predict the curve</p>

<p>That doesnt make sense ihatesttaking.
You have 8 as a vector alone. How can you conclude that the value of the resultant is smaller than 8? You’re adding the vectors. Not subtracting. So 6.23 does not make sense.</p>

<p>It’s hard to say. there were a lot of tricks.</p>

<p>It had to be larger. I eyeballed to save time and chose 11.</p>

<p>Hey guys, what would you predict 3 omits and 6 wrong to be about?</p>

<p>800 smileygirl32.</p>

<p>I think the curve should be 44=800 as usual. But it was trickier than June 2010 which was a laugh.</p>

<p>780-800, smiley</p>

<p>^^^Would be a bit lower than that. That comes out to -10, which, I’m pretty sure a 40/50 isn’t a 800, unless the curve was of epic proportions.</p>

<p>so 4 omits and one maybe two wrong should be an 800?</p>

<p>smiley i think around 740…?</p>

<p>raw score of > 44 usually is 800</p>

<p>Alright- thanks! I thought it was a bit trickier… I was going through it and the beginning half was pretty simple but then the later half really got me. Hopefully the curve helps us out!</p>

<p>did any of you guys get like 4 As in the beginning of the test?</p>

<p>hmm i remember getting a bunch of a’s and b’s for like the first 5-10 questions?</p>

<p>the curve will probably be >43 for an 800 there were a few more tricks and time consuming questions than normal based on what kids at my school always say
i have 1 omit and 1 wrong so far</p>

<p>but does anyone know the answer to the question where it was something close to 6n^2/3n does not equal 2n. which of the following is true? and the choices had something like (n)(n) cannot equal n^2???</p>

<p>same, pianoman.
jigpat, was that the piece wise one?</p>

<p>EDIT: nevermind, im thinking of the one that was like
Abs(x)/x. </p>

<p>did you guys get 2?
1- (-1)=2</p>
