<p>If there’s 1 line, then there are infinitely many lines that can be perpendicular to one line.</p>
<p>There was another question that said the “loci” of points … that was a pair of perpendicular lines</p>
<p>-Question with (x,y) plane and asking the # of lines perpendicular to one line - The answer is “infintely many” </p>
<p>NO. it said how many points are equidistant to two intersecting lines, so it would be two perpendicular lines! I had infinitely many until i reread the question. unless there were two questions that were similar & i’m mixing them up?</p>
<p>It said (x,y,z) coordinate system, but it never specifically stated 3 dimension</p>
<p>^^it said at one point though. A line can only have 2 90 degree angles at one point on top and one point on bottom</p>
<p>Any predictions on the curve for the test?</p>
<p>
</p>
<p>There were 2 questions that are similar. One had one line and asked how many lines were perpendicular to it,</p>
<p>Another asked all the poitns equidistant from 2 intersecting lines - that is 2 intersecting PERPENDICULAR lines. That question had the word “loci” in it.</p>
<p>I assumed in both questions that they were talking about a 2d plane</p>
<p>At least, that’s what I remember, i hope</p>
<p>edit that makes more sense then. i think i had infinitely many for something</p>
<p>Yeah, that’s what I thought Cacciato</p>
<p>Hm, I don’t remember any question with infinite as an answer choice, so maybe I’m just blanking out on the second question. Also, just wondering, are there different test versions?</p>
<p>There is only 1 version I’m sure.</p>
<p>Keep in mind I could be making a mistake too. I’m not foolproof, so everything here is really up to debate. I’m just saying what I remember to the best of my ability.</p>
<p>I assume that there’s just one test…</p>
<p>For the driving one, I got this for an answer: abs(10t-60)
Do you all agree?</p>
<p>DMOC, stop puting (x-2)/2 when everyone agrees it was (x-2)/3… and the answer to the other one was abs(10t-60)… that question was rele easy. you make up a value for t and plug it in all of the answers. (a very effective sat trick)</p>
<p>Oops, taht was a typo. Sorry. 
See I am clearly not perfect lol</p>
<p>I barely finished the test in time</p>
<p>I was on question 40 and had twenty minutes left, and then my TI 89 froze up saying busy when I graphed something. It did it for like 10 minutes. If only my calculator didn’t freeze, I could have gone back and finished some problems.</p>
<p>Omit: 4
Miss:2 at least</p>
<p>Wait what were the answer choices for the driving one?
Oh, and I used Barrons and found the time to be ridiculously long. Barrons I could NEVER finish. This test, I was almost 3/4 done at 40 min, so I thought she said 14 min o_O The last 15 problems or so were time-consuming though and I didn’t end up having time to check more than 3 answers. I so wish Math II were just SAT Math lol</p>
<p>i got lower than a 750 :(</p>
<p>
</p>
<p>Another effective way is to realize that both will be equal after 6 hours.</p>
<p>50 x 6</p>
<p>60 x 5</p>
<p>So you knwo the answer must be 0 when t is 6, and you work your way from there</p>
<p>^@ sunspark I was on question 39 when there were five minutes. miraculously, I managed to make it through 44</p>
<p>any of you think 4 skipped and about 3 wrong would be an 800 on this test? that’s a raw score of 42…</p>
<p>^I hope so!! I have absolutely no clue though about SAT IIs… Isn’t the curve usually a raw score 44+ = 800?</p>
