<p>I don’t think college board will round up that much…
If you miss five questions, that 1.25, after subtracting that from your number, maybe they will round up our scores. If it was 38.5 maybe to 39?</p>
<p>kelper that’s what i did too
compound interest needs to be conceptualized correctly. that way doesn’t compound the interest, just shortens the time period. that’s one of those things i don’t think i’ll get wrong again now that i know</p>
<p>courtesy of hookem:
…all you do is compound it quarterly, so:
starting amount x (1 + rate/4)^(time x 4). I got 3800+ or something similar</p>
<p>your score is always rounded after subtracting the decimal from the composite (i think that’s the right term)</p>
<p>hey dood for the |x| = |y|, it said wat it must be true???
ithought it was x^2 = y ^2 … its not x = y because x could also equaly -y</p>
<p>Man, that sucks. That’s two problems I know how to do, but I just didn’t do it on the test. I’m trying to put together a list of all the ones I know I missed. I put 2/9 for the probability question, but I’m just going to assume I got it wrong. So, I can only miss 5 questions to get an 800?</p>
<p>hey dood for the |x| = …,
ithought it was x^2 = y ^2 … its not x = y because x could also equaly -y.</p>
<p>
I put x squared = y squared, too.</p>
<p>that was one of the few ones i found easy. absolute value and squaring both turn the values positives. didn’t have to think twice.</p>
<p>It’s x^2 = y^2</p>
<p>I am 110% positive.</p>
<p>^agreed. Including bubbling, I probably finished that question in 5-6 seconds haha</p>
<p>so if anyone is looking for the curve for the official practice tests, i have it (from the book)
43/44-50 is 800. 33/34/35-42/43 above 700.</p>
<p>That’s amazing. My -6 is feeling realllllll good right about now lol</p>
<p>how did everyone approach the deep water problem?
was there any integration involved?</p>
<p>This test was totally LOL WUT for me. I answered 35 questions, and I feel quite confident I got all of them right. How much would 35 raw be on this sitting? (I know the book says 700 for 35, but c’mon guys, the curve has to be more generous after this sitting, riiiiiiight?)</p>
<p>I’ve already got 630 (oct) and 680 (nov).</p>
<p>Remind me of the deep water…I know I answered it…</p>
<p>Was the deep water the problem with the cosine?</p>
<p>y = 89 - 43cos (x)</p>
<p>Well, I figured that cos has a minimum and a maxmium…</p>
<p>Great, now that you made me think about it, I think I made a mistake. I thought that you could forget the cos (x) part and substitute 0 or 1, since the cosine graph has its minimum and maximum at these points, but now that I think about it, it would be 1 and -1. So you’d plug in those numbers for cos(x) and look at the difference between the two.</p>
<p>it was like 4.85 - 6.2cos(angle) something like that
and how deap it is from min to max??</p>
<p>was there anyway you could’ve just used the calculator?
can’t you find the inflection point on the graph, and integrate it to min and max?</p>
<p>Hmm, maybe you could derive it to find where the x-intercepts, and those would be the maxes and mins. I think you are just able to punch in 1 and -1 for the cosine part.</p>
<p>I graphed it and got 8.4 or w/e</p>
<p>isn’t it just asking for the range of the graph?
so i multiplied 4.2 (the amplitude) by 2 and got 8.4</p>
<p>futureEE:
[How much would 35 raw be on this sitting? (I know the book says 700 for 35…
I’ve already got 630 (oct) and 680 (nov).]
solid improvement. best/worst case probably 720 to 700 </p>
<p>y = 89 - 43cos (x)
this specific problem doesn’t look familiar after plugging it into the calc, but when, like this, they ask from min max you can just trace it once the window zooming and sizing is worked out, amirite?</p>
<p>edit- actually i do remember 8.4. there was also an 8.5 option to throw you off</p>
