<p>:( I am sad now. I skipped 3 problems and got 2 wrong(periodic and 2^x one). If I miss one more I would be out of 800 range.</p>
<p>Can anyone explain how to do the A+B+C problem? And the largest interior angle one? I’m hoping for quite a large curve on this test, I found some very easy and others very hard</p>
<p>^For the largest interior angle one I think I either used Law of Cosine or Law of Sin. Can’t remember the specific question, though.</p>
<p>It would have been law of cosines, there were no angles given to use law of sines. I’m angry at myself for not remembering how to do that one, its so simple now that I think about it. I made a lot of stupid mistakes</p>
<p>can you omit 4-5, miss a few, and still get 790+?</p>
<p>lol</p>
<p>@mmj, I don’t know the easy way to do the a+b+c quesiton, but you could always, like me, just try multiples until you got it. The multiples were 33x36x39x42x45x48=4 203 239 040.</p>
<p>I already forget what the question was asking, what would the numerical answer have been?</p>
<p>I don’t remember any of these questions. Is the test different in every region? I live in Asia.</p>
<p>futurepolymath, that depends on what “a few” means. If you omitted five and missed 1 or 2 you have a 790-800 depending on the curve</p>
<p>To estimate “the middle” multiple:
(4 000 000 000)^(1/6) ≈ 40.</p>
<p>Another approach:
4,XXX,239,040 has to be divisible by 9, therefore the sum of its digits is a multiple of 9 (see [Divisibility</a> Rules](<a href=“http://www.artofproblemsolving.com/Wiki/index.php/Divisibility_rules]Divisibility”>Art of Problem Solving)).</p>
<p>4+2+3+9+0+4+0 = 22, so the remaining 3 digits should add to 5, 14, or 23.</p>
<hr>
<p>Divisibility Rule for 11 came in handy on one of the recent Math 2s.</p>
<p>Soooo for that pyramid with a square base what would be the answer?
I seriously don’t remember what was labeled as “15”</p>
<p>Here it is drawn out:

<p>I choose in between and .1</p>
<p>There was one question that asked for the vertical Asymptote if x = 2…then gave bunch of eqations…was the Answer for that one the option with a denominator of (x-2)?</p>
<p>For the “middle multiple” one, I literally multiplied consecutive numbers until I got the exact number…yeah, a criminal misuse of time but I still had ~20 minutes left by then…The answer was 5.</p>
<p>Wow, I wish I had that much time left.
That question was the only one I left omitted.
I knew there had to be a clean way of solving it using multiplication rules, but I didn’t have time to have the insight come to me.</p>
<p>Someone should respond to my question :)</p>
<p>BUMP!! Answer my question please!!!

<p>@xnakelx: absolutely! when x approaches 2, that expression approaches infinity! So there has to be a vertical asymptote there!
EDIT: Does anyone remember a question in which there was something like sign of “a”. was a>0 or a<0? I narrowed it down to two options and chose a>0. Can anyone please tell me if I am right or not?</p>
