<p>Ken’s way works as well.</p>
<p>lollol, it wasn’t that problem exactly; I was just estimating.</p>
<p>So can anyone agree on the is it four sets or 5 sets that work for m=n? Unless we already reached a decision, i think it was 5, which i cant figure out why cuz i was pretty certain it was 4 when i tested it (which was tedious as hell).</p>
<p>^ basically it depended on whether or not you used (0,0). I didn’t, but I was probably wrong.</p>
<p>Wait- but you cant use [0.0] because its 2^n=4^m. If n=0 then 2^0 = 1. then the only thing that makes 4^m= 1 is m=0, but because m cannot equal n, then 0 is not a solution, ergo its 4, not 5 pairs, no?</p>
<p>re. the “deep water” problem, I just graphed it and found the difference between min and max… 8.4 sounds about what I got… If I’m remembering the right problem.</p>
<p>I WANT SCORES NOW :)</p>
<p>Anonymous91: did it say that they can’t be equal? I F’d that question up because I had skipped it and had about 15 seconds to answer it at the end but most people seemed pretty sure it was five so maybe they can be equal… ?</p>
<p>No they didnt say they couldnt be equal, but i assumed that because they were different variables (m,n) that they could not be equal, but perhaps i am wrong.</p>
<p>Based on previous Math2 curves, is it terrible that I left 10 blank this test? I want at least a 600 because I already have 1 other good SAT2 score. And I feel like I did VERY well in Biology M today. </p>
<p>Side Question: for UCs (which ask for 2 scores), will a score below 600 (which I guess I’m getting just because of the number of blanks) hurt me in any way if I have 2 scores above 700? In other words do they look at the 2 700s or do they try and analyze all of my scores holistically.</p>
<p>anonymous, im pretty stupid and i think i screwed this test up major (7 blank, prolly lots wrong), but i cant really recall that it said they cant be equal. although if ur right, i prolly wouldve missed it anyway since thats a pretty good trick… i need to read questions more carefully…
and to be really honest i thought that was pretty hard in c omparison to the 2 tests in the blue book… sheesh… the vector one, the last one with absolute value of sec x, the xyz plane one (ah stupid z axis…), the one with triangle and square whatever that i spent WAY WAY too much time on and still left blank… and oh boy… lol
should i cancel? i already took it once in june and i got a 710… any help would be appreciated</p>
<p>^ I believe they only take the top 2 scores when calculating your ‘points’
but a low score might still have some psychological thing working against you though…?
I’m debating on whether to cancel chemistry or not…</p>
<p>My friend put 9 blank and got a 780 on thenov.</p>
<p>^^^^^^did he get all the ones he answered right?</p>

<p>And finally for #49 (local and ld calls) - the majority says p=2/9.
I can’t recall the exact phrasing of the question, so I would not argue.</p>
<p>Did I miss anything?</p>
<p>=====================================</p>
<p>The [draconian] policy on non-posting test questions has a serious rationale.
PM me if you need to know more.</p>
<p>The one with something/ 2^t? And also are you sure conic was (2,3) i thought it was (3,-2)</p>
<p>^totally not sure about (2,3). Now that I look back I think it’s (3,-2).</p>
<p>/2^t??? Gimme another hint. :)</p>
<p>nice, gcf! Yeah, I know what lolilaughed is referring to. It was like, if something begins with an amount Mo and shrinks in half every hour, what is the equation that models its growth pattern in “t” hours? Now, the standard Mo x (1/2)^t wasn’t an answer choice, but by algebraic manipulation, I believe Mo/(2^t) was…does that sound right, lolilaughed?</p>
<p>Yea the “t” hours question and it I’m pretty sure it was E, something/2^t</p>
<p>I am blanking on this one. I hope I did not miss it and misbubbled the rest. :eek: :D</p>
<p>Edit: Thanks, hookem!</p>
<p>It was the easy-med section of the test.like a very long word problem where you had to translate what it was saying to a usable equation? I just plugged in numbers and came up.</p>
<p>The answer choices were weird since most of them were decreasing when it should have been increasing?</p>
