<p>what was the LCD question?</p>
<p>@ theman755 : i think 30 can be anywhere from 6-8 wrong choices.i have an account on ACT test prep, got 4 wrong, and the score was 34.</p>
<p>Awwww, I didn’t recognize that it was a 45-45-90 triangle I guess.
I found the distance between A(-2,0) and B(0,4), and put that over the distance from A(-2,0) to C(4,0).
Pooper scooper.</p>
<p>I hope that’s all I missed…</p>
<p>what was the one about the sin/cosine graph mutation?</p>
<p>it was cosx to cos(x-pi/4) + 1</p>
<p>so it moved right pi/4 and up one</p>
<p>Oh and there was one that was like x^2 + y^2 = 256, what is the biggest value x can be so that y remains a real number? Or something like that?</p>
<p>That was 16, right?
The other answer choices were huuuuuuuuuge.</p>
<p>ya it was 16</p>
<p>Disregard what I just said, I read the post wrong.</p>
<p>Yeah 16 so you could make x=16 and y=0 so 16^2 + 0^2 = 256</p>
<p>Haha that’s what I thought.
I was feeling kind of insecure about that one at first because I was like, “Is the ACT really asking me this?”</p>
<p>I actually ended up skipping that question. Imagine me, with my 740 Math SAT, having to skip question 5 on the ACT exam. I went back and was like “***? this is so easy!”</p>
<p>I ran out of time in the end and I had to put the second answer choice for the last 5 questions…were any of those right?</p>
<p>does no one remember the arithmetic series maximum and minimum numbers??</p>
<p>I believe it was 13 and 37, exclusive, but I’m not sure.</p>
<p>but it went by, like, 3’s I think</p>
<p>Oh yeah I remember that question, I don’t remember the answer.</p>
<p>I didn’t use a formula or anything on it though- I wrote out the numbers because there were only like 5 in between 13 and 37, if i remember correctly… 
I just know that you could count the numbers, you didn’t have to use a formula.</p>
<p>Wasn’t the answer to that problem 6?
If so then the numbers did go up by 3</p>
<p>Unless I have gone completely bonkers, I’m pretty sure the answer to that question was 7. Unless I counted one of the originals, in which then, **** me.</p>
<p>Oops, sorry, I meant 7!</p>
<p>Phew…</p>
