<p>^^ When I graphed it it only looked like 0 but then I checked the table for 2/3 and it was 1 too.</p>
<p>^^ no
it was 0 and 2/3</p>
<p>@liv yeah</p>
<p>anyone remember the answer to the question about cylinder height?
and a similar one (also about cylinders) that asked for the radius?
for some reason whenever I try to remember the questions from the test, I get them mixed up with the ones on the practice tests that I did last night… :P</p>
<p>intooblivion, HOW?! dang thats 1 wrong.</p>
<p>jrp, yeah that one was easy haha.</p>
<p>does anyone remember the exact wording for the last question?? did it ask for could be true or must be true? and were the answers I, it crosses both planes, III it cross one or the other of the planes</p>
<p>i think the answer to one of the cylinder questions is 60 or that could be a different one.</p>
<p>OH WHAT DID YOU GUYS PUT FOR "which of the following is untrue of the equation y=2+3sin(2x+3).</p>
<p>I put E, period is pi/2. Isn’t the period just pi? period = 2pi/2 = pi???</p>
<p>Unless 2/3 was a hole or something…but I don’t remember the function…</p>
<p>so you guys are sure that the n^k one is 30 ot 6…im going to jump off from the world trade center now</p>
<p>the one relating k with sin and cos, wasn’t the answer like</p>
<p>k/(sqrt(4x^2+1)) </p>
<p>?</p>
<p>@cortana I put down E also</p>
<p>@Rennir The answer WAS 2/3 and 0. I THINK the equation was 3x^2-2x+1 The key was to NOT rely too much on your calculator because it looked like 0 was the only root, and plugging in whole numbers wouldn’t help. They purposely asked for when f(x)=1 because they wanted you to get rid of the “+1” and then find where f(x)=0 Then you get x(3x-2)=0 and then x=0,2/3</p>
<p>@cortana: Yeah I got that one.</p>
<p>"which of the following is untrue of the equation y=2+3sin(2x+3).</p>
<p>i didn’t say that; i think i said A. anyone else?</p>
<p>me too steven ^ im going to stop reading this thread before i cry</p>
<p>i asked this before, but is a 780 on the math 2 test really that bad?</p>
<p>@liv I remember that the answer had a “k” in the numerator AND denominator… :/</p>
<p>…andddd i think i’m wrong. dang it!</p>
<p>no 780 is a great score.</p>
<p>i could’ve sworn there was an answer that was also impossible (aside from the period being only pi, which is obviosly true)!</p>
<p>yeah this thread is totally killing my confidence but I can’t stop reading b/c I really want to know how many I got wrong 
4 and counting…</p>
<p>For the last question, did anyone else get I and III as an answer? The question asked which numbers could be true, and it was the one with the 3 planes and 3 lines.</p>
<p>I was that it intersected both planes at the other two lines that weren’t mentioned yet
II was that it was parallel to both planes (but they intersected, so they can’t be parallel to each other)
III was that it was parallel to exactly one plane</p>
<p>None of them HAD to be true, but it was possible for I and III to be true I believe.</p>
