December 2009 Math II Discussion

<p>GAHHH, DUUHHHHHH. I WOULD omit the easiest question ever. O_O Thanks ya’ll. So far 1 omit and 1 wrong, but I think I put B for the driving one so that makes 2 wrong… excluding the [0,-2] one… :/</p>

<p>LOL i just sent my complaint e-mail join the fight!!!</p>

<p>ilikebananas,</p>

<p>remember, it’s an inequality.</p>

<p>Not meaning to nitpick, but if we sound more formal, they may take us more seriously. ;)</p>

<p>Wait… doesn’t the fact that the interval was written as (0, 2) - open interval - as opposed to [0, 2] - closed interval - mean “less than”?</p>

<p>Yeah, feel free to point out errors in my e-mail template! Thanks for letting me know.</p>

<p>@fledgling
That’s what I’m trying to say, but everybody wants to go to CollegeBoard and complain about the question. </p>

<p>You guys don’t honestly believe they’ll rescind it, do you? Just because 5 people got the question wrong doesn’t mean that they’ll drop it.</p>

<p>wait so is the answer [-3,3] or [0,2]?</p>

<p>The driving one was:</p>

<p>abs(50t-60(t-1))
abs(50t-60t+60)
abs(-10t+60)
abs(-(10t-60))
abs(10t-60)</p>

<p>I don’t remember which answer that was. . .</p>

<p>For the perpendicular problem in the (x,y,z) plane was the answer infinite amount of times?</p>

<p>agreed with ahage16!!</p>

<p>It was definitely choice A as I said, but I don’t think your first one matches that first. There was definitely only 1 t in the answer</p>

<p>yeah sunspark that was the answer.</p>

<p>It was answer choice A, I believe.</p>

<p>Sorry guys. CC doesn’t let me edit posts.</p>

<p>Question 36ish, the one with 3x-2 function equaling x: (x-2)/2 (Choice E)</p>

<p>-Question 41: 3 (Choice D) – still unsure if this is right but others say it is</p>

<p>-Question 42: 5.82 (Choice E) - with the 2 triangles</p>

<p>-Question 45: Statements I and III were true (3 trig functions and it said which ones equal one always)</p>

<p>-Question 50: 2 (Choice B?) - used gauss jordan</p>

<p>-Question that had the table of frequencies and had the frequency of 4 equal x — that should have been “x = 4”</p>

<p>-Question that said the center of the circle is at (0,6) — I said -8 and 8</p>

<p>-Question that said “if 14 and 10 are removed from a set of numbers equaling 240, then what’s the remaining average … blablabla” — the answer was 21.6</p>

<p>-Question that asked the frequency of the sine graph — freq was 1/pi</p>

<p>-Question with probability - 7/15</p>

<p>-Question about what doesn’t change - standard deviation</p>

<p>-Question about r and q thing - negative q</p>

<p>-question with weird function: (0, z, 0)</p>

<p>-Question with someone driving and someone else driving to catch up: (Choice A) (sorry, forgot the actual answer</p>

<p>-Question with geometric sequence: n^2 + 2</p>

<p>-Question with 2 lines and they asked what are the points equidistant: 2 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>-Question with a limit as x approaches 2. Answer - 5</p>

<p>-Question with “a” = ax -2 or something like that, it was “2” for the answer</p>

<p>@ahage I put the first one</p>

<p>Another question: the question that asked as x approached 2
did you guys get 5?
Cause I factored out the numerator and canceld (x-2) on numerator and denomitar and plugged in 2 in (x+3)</p>

<p>YES! will add that</p>

<p>also added the a=ax - 2 question to my previous post</p>

<p>Why is it infinitely many? It’s a set line right? So shouldn’t it be a pair of perpendicular lines?</p>

<p>I just guessed infinite because it was a 3-dimensional coordinate system</p>

<p>^I thought the same</p>

<p>when did it say three dim? I don’t remember that…dAMN</p>
