October 2009 SAT II - Math Level 2

<p>I guessed 4.8. Considering my luck today, it was probably wrong.
Did you guys think it was much harder than practice tests?</p>

<p>@monstor344</p>

<p>Wasn’t the question about a cylinder? I don’t remember a cone one at the end. If it was about a cone, then damn…</p>

<p>I remember one with a 6 cm tall cylinder. I said the answer was 3cm.</p>

<p>i got 3 for the cone…i did a ratio w/ the height and volume…yup, im wrong</p>

<p>@RedCatharsis: Don’t the imaginary roots come in conjugate pairs? So, if there was one imaginary root then there should be another imaginary root as well which is its conjugate pair.</p>

<p>@Randwulf you misread the question :p</p>

<p>what was the answer to the -sinx abs(sinx) and cosx graph question?</p>

<p>Abatis we’re completely ignoring imaginary roots. That’s why.</p>

<p>

I don’t think you need to use imaginaries. Let f(x) = (x-2)(x-3) and let g(x) = (x-2)(x-4) and the roots for h(x0 end up being 2, 3, and 4.</p>

<p>@Twaan -sinx and abs (sinx)</p>

<p>how can -sinx and abs(sinx) be the same graph?</p>

<p>the question was something like this:</p>

<p>a 6cm tall cone divided with a plane parallel to the base so that two parts with equal volumes would be formed. what is the radius of the small cone that is created? the radius of the original cone was 3.</p>

<p>Crap. Well then my tally is 3 omitted and 2/maybe three wrong. </p>

<p>I’m still hoping for an 800 :D</p>

<p>one of the answers was 29.69 yea ? the one with the triangle with the diagonals of a cube and sides of 7. Also the alarm probabilities one, i know i got 0.997 but im scared i circled the wrong choice, does anyone remember if it was option A?</p>

<p>Ah. Okay. Thanks! 1 wrong so far, then.</p>

<p>2.4 becuase 4.8/2.</p>

<p>for the one where (0,0) and (73, 83) are points of a line…it said how many coordinates are there not including the endpoints or something. was it 73?</p>

<p>Twan it said only for the domain 270<x<360, i got it wrong as well… made lots of calculator entering mistakes. So far 5 wrong and 4 omit</p>

<p>For the roots question, I multiplied two quadratics on my 89 and then set them = to 0 and solved. I tried it with three different pairs of quadratics (with 4 DISTINCT zeros) and got 3 and 4, so I went with that.</p>

<p>Also, for the triangle question and the length of AB, wasn’t it sin(2theta)?</p>

<p>What about the question “How many integral units pass through the line that extends from the origin and (73,82) (something like that”? I had no idea how to do it, but I thought calculus and integration :D.</p>

<p>I got 29.69 as well.</p>

<p>SAT MATH II Score Formula</p>

<p>[sin(Number of Harry potter books you read)* Temperature Outside]*[Age + Number of Pencils you had during the test]</p>

<p>Round Answer Appropriately
i got 700 :D</p>
