June 2006 - Math Level 2

<p>anyone remember the xln e = -x or something like that?</p>

<p>I put 1 but other people put .27.</p>

<p>This test was much easier than any of the barrons tests, and a bit harder than the Princeton Review ones.</p>

<p>"This test was much easier than any of the barrons tests"</p>

<p>I agree.</p>

<p>hmmm </p>

<p>lnx = e^-x what does ln x equal</p>

<p>to get 1, x would be e
ln(e) - (e**-e)
0.93401196415468746</p>

<p>sorry, e<strong>-e is a really small number (</strong> = ^)</p>

<p>ln(1.31) = 0.27
e**-1.31
0.26982005638468687</p>

<p>ln(1.31) - e**(-1.31)
0.00020708082837334052</p>

<p>Looks like 0.27 was the answer. I can't remember what I put down very well but I know it was not 1</p>

<p>If 1 was the answer that means
lnx=1
x=e</p>

<p>and </p>

<p>e^(-e)=1</p>

<p>which is not true, because we know e^0 =1</p>

<p>Aseemo - maybe we aren't talking about the same question. I vaguely seem to remember a question about transformations that was different than the circle transformation...</p>

<p>hey yea the circle question was like asking what is the equation, but there was another question i think that had the origin as part of an original function, and asked which point MUST be in the function f(x-2) +3 or something like that</p>

<p>Reposting this. Does anyone remember if any of these were C?</p>

<ol>
<li>It said to give the formula for the b(n) term of the arithmetic sequence.</li>
<li>THe one where it gave you domain and said which isn't in range. (feel like an idiot for not understanding this problem.)</li>
<li>The one where it had log in base 2</li>
<li>The one where it said something about flipping around the origin on the x=y line.</li>
<li>The area of the trapezoid in the parabola</li>
<li>The slope of with the two parameters equations.</li>
</ol>

<p>So far I've gotten the following response:</p>

<p>the trapezoid question was C
log base 2 question ws E
arithmetic sequence was C,D, or E
domain was E
can't remember parametric
flipping around x=y line was E</p>

<p>Does anyone know for sure what the arithmetic one was and what the paremetric one was? C HOPEFULLY!?</p>

<p>I just remember getting a ton of C's throughout the test.</p>

<p>I forgot if it was this one, but I remember a lot of Cs and for another test a lot of Es</p>

<p>the arithmetic sequence was d, that is if I'm remembering it right.</p>

<p>Admanrich - yes! I was thinking the exact same thing! Like, for the first three pages, I had almost all C's and I was thinking "wow, this is weird.. I wonder if anyone else noticed this."</p>

<p>Heh, wierd. I remember bubbling a lot of c's for the chem one.</p>

<p>Haha good! I was like OMG why are they all C's</p>

<p>^ for chem I remember getting a ton of A's and E's</p>

<p>So you guys think that I got at least 2-3 of those right by guessing C? Because I know I missed one for sure....meaning that I can miss about 4-5 of the ones I guessed on (I guessed randomly on 7...can't remember the last one). Hopefully, I didn't miss more than 1 more on the ones I actually solved.</p>

<p>Do you think it's possible for me to still get an 800. You can miss 6 if you don't omit right?</p>

<p>Sequence was D i think (n^2 something?)
Parametric was B (-1/3?)</p>

<p>If you're sure you got 43 right, guessing on the other 7 should still give you an 800.</p>

<p>I put -1/3 on the parametric one too.</p>

<p>hey guys, so if i'm aiming for an 800 and i'm positive i missed three (maybe one or two more for careless) i'm still fine, right?</p>

<p>Definitely. I'm not sure about 5 though, depends on the curve.</p>
