<p>does anyone remember the question: how many times does this function cross the x-axis? f(x)= xy^5-2x=3y+1 (or something like that?)</p>
<p>As for the imaginary numbers one, it was A (I think), whichever letter was the higher letter in the 2nd quadrant. Explaination:</p>
<p>On the real axis, the point was (-a,0) and on the imaginary axis, the point was (0,bi).
Thus, adding the points, you get -a+bi. (if that wasn't the question, sorry, since i don't remember it completely right now. i think that was the question though)</p>
<p>my question: the one with point P 6inches from plane M. How do you work that out? For some reason... complete blankage in my mind );</p>
<p>what do you think 6 omitted and 10 wrong is? I just want to see what an estimate (conservative for 10 wrong). That doesn't seem very good.</p>
<p>ditto i want to know to...i feel bad now</p>
<p>@duchess
good point, i read the axis wrong. I thought that was the visual representation of the data distribution...not a frequency chart. -_-;</p>
<p>"what do you think 6 omitted and 10 wrong is? I just want to see what an estimate (conservative for 10 wrong). That doesn't seem very good."</p>
<p>660~?</p>
<p>i have a strong feeling im going to end of retaking it i left a couple blank plus now it seems i got 2 wrong so far (the easy ones =[)
i was just really shaky for some reason
and ran out of time =[</p>
<p>Well i think i got under a 700 so ill just take it again in oct. oh well.</p>
<p>How does 4 omitted and 1 wrong look? I hope there weren't any stupid mistakes -_-.</p>
<p>what will i get? i dont think i missed any but i omitted 10 ;;;;;;;
(did not put some of the answers on the answer document)</p>
<p>ap that looks like an 800</p>
<p>is the official book of sat subject tests from college board accurate in terms of determining the score? or does it vary a lot from year to year...cause you can omit up to 5 and still get an 800 according to it</p>
<p>TY, I pray I don't make careless errors...</p>
<p>You are a careless error...Lol just kidding, I am sure you were deliberately created.</p>
<p>Anyways, I am in the same situation as you AP currently. Are you taking the BC exam on Wednesday?</p>
<p>Did you put E: a = -3, c = -1
For which of the following has no real roots?</p>
<p>y = ax^2 + 3x + c was the equation. I am 100% sure it is E.
Actually I am not asking if it is E. I am just contributing to our pool.</p>
<p>Marathi power.</p>
<p>kapwatt- I think I put A for that one. I think it was because a and c were positive, and b^2-4ac must be less than 0. so 9-4<em>a</em>c < 0. but if -3 and -1 was a choice, that would work too. ???</p>
<p>well kapwatt, you're right. it is E i'm pretty sure. the trick of the question was to plug it into the quadratic formula, and E was the only one that gives you a negative value under the square root (I forgot what that part is called). so you have to end up factoring out a i, which makes the answer imaginary.</p>
<p>^I got E also for that.</p>
<p>Precisely. The discriminant. I think we got all the tricky ones in this thread. Hopefully none of us made any other mistakes.</p>
<p>the curve varies with each test. if everyone did well, then it'll be a low curve. if everyone did bad, it'll be a higher curve. for instance, a raw score of 44 can be 800 on a test with low average score while it can be 780 on a high average score. so if everyone didn't do good, we get a higher curve.</p>
<p>Well I am a nice person. But if you are suggesting I agree with your aforementioned philosophy, I hope you failed heyli.</p>
<p>=)</p>
<p>I'm pretty sure the curve is predetermined. Plus I think the curve for this test will be on the slightly generous side; this test is slightly more challenging than the released exams, I think.</p>
