January 2010 - Math Level 2

<p>Haha, that’s respectable…
I wondering about the same question as Rtgrove123.
It was like N is an integer and so is K. what number is N if 180 divides N^K
It was probably 30 because 30^2 = 900 and 900/180 = 5
but the wording was confusing. I put 30 but if K = 1 and 30^1 = 30. 180 cannot divide 30.</p>

<p>mrdoodle65</p>

<p>yes it was</p>

<p>mrdoodle65 do u remember if 4.7 was an ans? 'cause if not, then i got 4.9 too on the quadreg problem~</p>

<p>wow then I got 2 wrong and skipped 1… I’ve honestly never even heard of quadratic regression and I’m in ap calc… lame…
I also don’t have a ti89 to work it out for me</p>

<p>i dont really remember the answers… but 4.9 is in the solver on my calculator so i’m pretty sure i got that</p>

<p>You can figure out a quadratic regression on a TI-83.</p>

<p>Ya…I still have values stored on my calculator and it was 4.9</p>

<p>does anybody know if the scores can be curved so that our scores come out to be higher than the ones listed in the official collegeboard book.</p>

<p>b/c i’m thinking of cancelling my score since i already got over 700 and was striving for 800 but i don’t think that’s possible with 5skip and 4 wrong so far…wow i made so many stupid mistakes…</p>

<p>wow i think im looking at about 6-7 missed questions</p>

<p>but from the sounds of it, it seems like it was a difficult test for most people.</p>

<p>do you think the curve would be really lenient on this one?</p>

<p>anyone get the similar triangles problem? or choices… there were like 2 triangles inside each other.</p>

<p>Its possible, if like everyone gets certain questions wrong. But it’s unlikely. You have a few days to decide though, take your time</p>

<p>mrdoodle65
i believe it was tany
or something
which ever angle was in the small triangle, but not in the large triangle</p>

<p>blizzard do you know if that was choice C? cause that’s what i remember putting</p>

<p>i believe it was
lol
but im not completely sure</p>

<p>i just remember the answer
sorry man :(</p>

<p>yup i got tany too~ and the quadreg que im pretty sure its 4.9 then</p>

<p>any other seemingly difficult questions that anyone remembers?</p>

<p>I think we should continue with blizzard’s plan if no one else has any specific questions. We should list each problem in order. I listed 1 and 2 previously. I think jansat listed #3. Does anyone remember #4?</p>

<p>Oh, if you were talking about the physics problem with Vo and stuff then yeah, I remember getting 599.
It’s been established in the other thread that the answer to the regression problem was 4.9…</p>

<p>Sorry idk what number four is, but for the question about the graph, the answer was y=2f(x+4)-3 right?</p>

<p>and also the question where it said f(x) = g(x)(x-2) + r for all values of x and what is r. something like that, what did you guys put?</p>
