<p>lol! Yeah they should have used better wording for that problem. Hopefully it’ll just help the curve.</p>
<p>Ugh this was harder than I expected. I guess I kinda deserve it cause I started studying last night from 8-12 PM by taking the diagnostic and one Barron’s test and skimming the book.</p>
<p>I know I got the quadratic regression one wrong. I remember seeing that phrase in Barron’s towards the end on calculator functions and though “Oh this shouldn’t be on, there should be more conics/matrices/three-dimensional graphs tomorrow” NOPE. I put 5.2, pretty upset that it was 4.9.</p>
<p>I also skipped #38 with the f(x)=g(x+2)+r. I don’t know if it’s pathetic that I’m in BC Calc & don’t know how to do it or if it was just a REALLY obscure question.</p>
<p>I just started reading #47 at the end when the proctor announced time was up. I saw a string of Es right above that so I dumbly put 47 as E to continue the chain but I think I’m wrong on that from what I hear? It was the x^2+cx+24 (something like that) with one zero being double another. I just finished reading the problem when I had to stop so I didn’t get to do any work.</p>
<p>So from what I know, 4 skipped/2 wrong–>how bad shape am I in?</p>
<p>Physics one=find the maximum height of the object? I don’t remember the exact answer but you just had to set the derivative equal to 0 and plug X back in to the original equation. Calculus <333</p>
<p>CrzyGmer, if you got the other 45 right, you’re in good shape. Thats a definite 800.</p>
<p>Edit: Seeing as you edited it. 4 skipped 2 wrong is still a raw score of 44, which still should be an 800.</p>
<p>Okay thanks. 44’s usually the lowest raw score for an 800 right? Hopefully it’ll be a 43 (or maybe even a 42 but that could be pushing it) cause the general consensus is that it was a very long test.</p>
<p>What is the worst case scenario where you could get at least a 720 like how many wrong and how many skip</p>
<p>Why was the answer “2 is a prime number”?</p>
<p>I put the like choice C or D where it gave an example like “(15*2)…[forgot the rest]”</p>
<p>also, for the question asking doing what would cause the entire equation to be cut in half, what did u guys say?</p>
<p>lol or u could have simply graphed it and found the max</p>
<p>True. I don’t have the patience to adjust my windows though.</p>
<p>Mabsjenbu,</p>
<p>I believe the prime number question gave you the statement, “All primes numbers can be expressed as 2k + 1, where k is an integer” and you had to prove it false.
E. 2 is a prime number, disproves it because 2 is a prime number but cannot be expressed by 2k+1 where k is an integer.</p>
<p>For the question where you had to halve the entire expression, I believe it was II and III, divide e by 2 or multiply f by 2</p>
<p>hmm ok</p>
<p>And for the question about halving it, I remember only putting one (manipulating whatever was on the bottom - e I think) because didnt the top have something like</p>
<p>Constant + x/y </p>
<p>So I thought affecting either of the two variables wouldnt really halve it because of the thing being added.</p>
<p>So is there a consensus on the question about the trig functions
like
sin(2x) > …
etc
etc</p>
<p>I only put one of them for that one too mabs…I think it had 2 do with F…though I don’t remember</p>
<p>A question about the ln(sin x) = 0 question;
ln(sin x) = 0
sin x = 0
x = 90 = pi /2</p>
<p>but the question said 0 < x < pi/2, didn’t it?</p>
<p>just wondering.</p>
<p>@Rt</p>
<p>hey good to see you on the boards :)</p>
<p>Do u remember choosing a variable from the top or the bottom?</p>
<p>I don’t know if I should cancel my score.
On the practice tests I had been doing fine,
but today I really had time problems…</p>
<p>Omit 3, wrong 3.</p>
<p>What’s the curve usually, and they round up & round down the decimal pts, right</p>
<p>mabs-</p>
<p>Nice to see you likewise! </p>
<p>I remember it being on the bottom. Though, now that I am thinking about it…mushroom maybe right.</p>
<p>Mabs, I don’t think there was a consensus on that trig problem because no one could remember it perfectly.</p>
<p>Lylask, I believe it was 0 < x < pi, so x = pi/2 would work.</p>
<p>Also, Omitting 3 and getting 3 wrong will get you a raw of 43, which still might be an 800 if you’re lucky.
They round how you’re supposed to round. 1.5 rounds up to 2. 1.49 rounds down to 1.</p>
<p>I also got the P=2k+1 to be E, cause 2=2k+1, k=.5 and k has to be an integer. And I got II & III for the halving the entire expression (the one that didn’t work had to do something with term c)</p>
<p>If you remember the exact problem for the halving problem, I might be able to help explain it.</p>
<p>I don’t remember it exactly, but I got the same answer you did so I trust that it’s correct. Scores come out the 11th correct?</p>
