CONSOLIDATED October 2011 MATH (better organized)

<p>@DancingBear
Do you think it might have been because the the questions this test were different than usual? Because I thought the March this was average, but this one seemed really easy to me.</p>

<p>@LoseYourself</p>

<p>No, the question asked for
f(x) + h(x) = g(x)</p>

<p>The columns were arranged
f(x) h(x) g(x)</p>

<p>Correct answer choice was 0
11 10 -1</p>

<p>@DancinggBear
It was 0, trust me. I intially put 1 because I thought the columns were organized in the same order as the equation, but I realized they weren’t and changed my answer.</p>

<p>It asked for what value of x was f(x) + h(x) = g(x)</p>

<p>it was</p>

<p>x | f(x) | h(x) | g(x)</p>

<p>1 | 2 | 3 | 5</p>

<p>elementi explain.</p>

<p>The columns were x, f(x), g(x), h(x). You had to add the outer two columns, completely sure.</p>

<p>Oh poop.</p>

<p>10char</p>

<p>The columns were organized as you said, but it asked for</p>

<p>f(x) + g(x) = h(x)</p>

<p>x | f(x) | h(x) | g(x)</p>

<p>0 | -1 | 10 | 11
1 | 2 | 3 | 5</p>

<p>can someone explain the sequential question to me? the 1024 one?</p>

<p>Well it’s ok. The curve will be -2 800 /crying in disillusionment.</p>

<p>ahhh. ok thanks. i did terrible :'(</p>

<p>yea this sat math was so wierd. I have seen tons of people who said they got 6_ _ in march/may/june w.e. and are saying they got high 700s or 800 yesterday. Personally I got 670 in may and feel like i got 770 yesterday. This may just be correlation and not causation cuz I think if people got 6_ _ last year then they probably studied math a lot, especially on college confidential. Just my 2 cents</p>

<p>@worriedteenager
But I didn’t study. At all.
For math at least.</p>

<p>so i asked this already but no one answered: for the answer that is a+b=70 was that choice C because all i remember is putting choice C for that one. </p>

<p>And also the arc one was 16 i thought. It asked how many times the arc of one angle was bigger than the arc of the other angle. One angle was 160 degrees and the small on was 20 degrees. and then the radius was 4. but when calculating the smaller angle, the radius had to be half that…2? does this sound right to anyone?</p>

<p>180 - 160 = 20</p>

<p>160 / 20 = 8</p>

<p>and I THINK it was C</p>

<p>@sm:</p>

<p>If an angle in a circle is smaller than another angle of the circle the “radius of the angle” for lack of a better name, does not change. In addition, I distinctly remember the radius NOT being given.</p>

<p>Did anyone else have a question about a box, with inside lengths of 12, you had to find out how many balls with a radius of 3 could fit inside it?</p>

<p>Yeah I think you guys are right. I put 8 at first but like always I like over thought it and changed it. AND I REALLY HOPE IT WAS A C, I cannot afford to get anymore wrong on math.</p>

<p>so far i have like -15 on math and -2 on writing…so awk i wish my talents were a little bit more balanced.</p>

<p>i remembered an answer about rt=w or something… or was that experimental</p>

<p>For the arc question, it was drawn to scale. You could have made marks (and found out that 8 fit perfectly) to check your answer. 160<em>2=320, 360-320=40, 40/2 (vertical angles) =20. 160/20 = 8. The circumference is proportional to the angle. Therefore, 8</em>20=160. there’s your answer. 8. I hope most people got this!</p>

<p>does anyone remember the question with a parabola that asked you to solve for k??
i think it showed the parabola and a point on the graph (-1,4) and the equation was y=ax^2 + k</p>

<p>If you’re referring to y=k(x-1)^2 then please read the master list of questions before posting. If not, then it was probably an experimental.</p>
