Official ACT Math Thread April 2013

<p>Did you get a pattern of E’s and K’s from questions 2-6?</p>

<p>what numbers were the coterminal and horizontal asymptote questions?</p>

<p>coterminal question: 60 degrees (25pi/3 radians = 1500 degrees, 4(360) = 1500 - 60.</p>

<p>horizontal asymptote question: this one really surprised me, because to really grasp the question quickly you have to have at least an elementary understanding of limits and end behavior models, which are most of the time taught in calculus. nevertheless, the answer was y = 2.</p>

<p>what number out of the questions were they?</p>

<p>can anyone post what the last ten questions were?</p>

<p>omaha, nobody knows that specific information… all we can tell u is that it was in the last 15 questions</p>

<p>yeah. I was just trying to figure out if they were in #50-60</p>

<p>@omaha Yes, they were. It was only the last two pages (as in front/back, not physical pages) that had the difficult problems.</p>

<p>I do remember #55.</p>

<p>x^2 - ax - 12</p>

<p>If 4 is a solution to the above equation, what is the other solution?</p>

<p>Naturally, the answer you get when you solve for a was one of the choices.</p>

<p>^-3 i think</p>

<p>Ah, the benefits of having a graphing calculator.</p>

<p>^the most true statement I have heard all day</p>

<p>Im sure you guys all did great on this ACT</p>

<p>anybody know around what number the pyramid question was?</p>

<p>omaha, why are you so considered with what number everything is??</p>

<p>because I had to rush through the last ten and I think I got many of them wrong. I just wanted to know which problems they were.</p>

<p>that makes no sense but whatever…</p>

<p>speaking of the pyramid question, what was the answer to that one?</p>

<p>^ If you’re talking about the one asking for the area of it, it was 340 I believe. It was answer choice B/G</p>

<p>was the Kw/h^2 one F, G, H , or J?</p>
