SAT II Math Level Two May 2012

<p>For the P^3 one, i think we all agreed that it was II only cuz there were more than 3 factors or something…</p>

<p>Yeah it should be 84 for the 50 degree vertex angle. I’m pretty sure that’s what I got.
Just use law of sines and multiply your answer by 2. then add to 25 to get the perimeter.</p>

<p>No need to draw a perpendicular.</p>

<p>Also the p^3 doesn’t have only 3 distinct factors. It had more than 3 (think 8, which is 2^3: factors are 1,2,4,8)</p>

<p>maybe… now i’m unsure… crap… what was the question for the bigger and smaller isocles triangles again? i forgot</p>

<p>Bigger and smaller isosceles triangles? What?</p>

<p>swoony, did you decide not to cancel?</p>

<p>also was 67 even an answer choice for the one with the single isocles triangle?</p>

<p>What was the two similar triangles problem?
Also:</p>

<ul>
<li>f(4.7), where f(x-1) if x is greater than 1 and f(x) if x is equal to or greater than 0 and less than one → answer: 0.7</li>
<li>intersection between ellipse and y=x → answer: (3.12, 3.12)</li>
<li>given the diagonal of a small cube (1.414) find the volume of the large cube made of 27 of the small cubes → answer: around 27</li>
<li>function f times function g produces how many zeros → answer: 6</li>
<li>birds on the island → answer: 6000</li>
<li>4, 5, 8, 8, 12, and an unknown integer → answer: integer is 11</li>
<li>rate of taxi (or telephone; it differed from test to test according to some) → answer: $1.25 + $0.75(x) where (x) is the smallest integer greater than or equal to x</li>
<li>r = cos(theta) → answer: (0.5, pi/3)</li>
<li>surface area of the cylinder → answer: 6(pi)(r)^2</li>
<li>number of triangles formed → answer: none</li>
<li>(x^-2m)(x^m) → answer: 1/(x^m)</li>
<li>arrangement of 8 cars with two in set positions → answer: 6!
-which y is not a function of x → E, or the one that did not pass the horizontal line test</li>
<li>standard deviation of the student’s score when compared to the rest of the class → answer: A (no one has posted a number)</li>
<li>x^2 +4 = 8 logic problem → if x =/= 2, then x^2+4 =/= 8 (which is FALSE)
-1.5x increase per year in population → answer: 338 (choice A)
-function was something like 3sin(2x+1) - 1 → -4<=f(x)<=2</li>
<li>f(x)=cx+3 g(x)=dx+1 → answer = quadrant 1, i graphed it</li>
<li>stem plot answer → 56 (according to some sources, i don’t remember what i put)
-terminal side → cscx < 0 ; secx > 0
-p^3 problem: roman numeral II only
-isoceles triangle problem → 84 if you had 50 degrees as the vertex angle</li>
</ul>

<p>@Studious: I really don’t know at this point. So far I think I still got 2 omit 3 wrong but at this point I can’t really be sure…I don’t remember my answer to the p^3 question and I’m not entirely sure what I put for the isoceles triangle problem. If I DID miss them that puts my raw score at 42, right? :confused: And I don’t even know if I missed anything else.</p>

<p>what was the one with the terminal side??? i dont remember that one</p>

<p>Angle theta terminates in the 4th quadrant. What are the signs of cscx and secx</p>

<p>also can anyone verify this?</p>

<p>x^2 +4 = 8 logic problem → if x =/= 2, then x^2+4 =/= 8 (which is FALSE)</p>

<p>someone said that was choice II, but I thought that was choice III…</p>

<p>It was most definitely choice II. It said x^2 + 4 = 8 if x = 2 (or -2?). The others neglected that x could be negative.</p>

<p>Edit: I’m willing to bet that the curve is fairly lenient. 42+ or 43+ will be 800, I think.</p>

<p>Didn’t it ask for the one that was false?</p>

<p>Yah i also think that the curve will be lenient!! This is CC for gods sake and a lot of people haven’t done perfectly well. I think the cutoff will probably be 43 and higher for 800</p>

<p>What were the last three problems on the test? Anyone remember?</p>

<p>And for std deviation it was A test score 1</p>

<p>swoony, most people remember it saying which was true. Don’t worry, you probably got it right. It was one of the easier ones.</p>

<ol>
<li>No triangle</li>
<li>Can’t remember </li>
<li>8 years</li>
</ol>

<p>AHHHHH 3 Omits and 2 confirmed Wrongs with 2 unsures. What do you guys think the curve is for an 800? will i make it??</p>

<p>■■■■ in crying right now!! That means I can get an 800. Oh thank u studious. If we both get into an ivy and its the same one ima find u and gove u a hug :’) thanks bro</p>

<p>Who agrees with me in that it will probably be 43 and higher for 800?</p>

<p>King, I agree with you.</p>

<p>YoungDerivative, you’re welcome! What grade are you in? It would be pretty funny if we both ended up attending the same Ivy.</p>

<p>11th. Praying for stanford or at least cornell. Lol</p>
