<p>What was the answer to the question with 0 < x < 30 as an answer choice?</p>
<p>I got 105/225 as well. 45% had fish to begin with, which is 90 and then the additional 25 people included 15 with fish.</p>
<p>@pk12ab, the asymptote one was y = 2 I’m pretty sure. I kept putting in random numbers for a and b in my graphing calculator and every equation had 2 as the asymptote.</p>
<p>EDIT: accidentally wrote y = -2, not y = 2.</p>
<p>Also, pk12ab, I’m pretty sure the asymptote for the rational function was y=2. Put it into my calculator and that was what I got (also just the general rule regarding the degrees of the numerator and denominator for rational functions corroborate it being y=2).</p>
<p>The horizontal aymptote is 2. To find it, only the lead terms in the numerator and denominator of the rational expression matter. it was 2x/x… so 2.</p>
<p>Thanks pk12ab. Sadly I missed both of those. So, I think my goal of a 36 is no longer possible "/</p>
<p>@relativelysmart I did the same. And I just remembered now end-behavior models. Damnit haha I should think about calculus more often.</p>
<p>Please explain the pyramid one. I know that if you took the difference of the two heights, it’d give you the slant height of the pyramid (which was 12 because 23-11=12). From there you’re supposed to use the PT to find the actual height (Hypot was 12, leg was 5). So all of the answers I worked gave me a radical in the answer. I was clueless on that question. </p>
<p>Also, anyone get that (a,b)<>(c,d) question? I kept getting like -12:17? Which wasn’t an awnser. Lucky me. This was a rough math section.</p>
<p>@relativelysmart, i forget the question, but 0<x<30 was the answer to that one. anything over 30 would have made the angle obtuse, and the angle was obviously acute.</p>
<p>59/60 after going through all of CC. Damn rhombus question LOLOLOL.</p>
<p>@efeens44 I like how we put the exact same reply with almost identical wording at almost the same time haha.</p>
<p>Whoops! Not sure what I was thinking there at all. Thanks for the correction guys.</p>
<p>Vann: Base of each triangle was found by subtracting x coordinates. Same thing with height. (b*h)/2 is formula for area. Multiplied by 4, plus b^2 (area of square) and you got your answer</p>
<p>@relativelysmart great minds think alike, eh? ;)</p>
<p>@Alpha 2014 What answer was the correct answer for the rhombus question?</p>
<p>What was the answer to the second to last question on math? It was about an arithmetic sequence where there is a common different and the sum of the first three therms was 80 or something. the question was like, “Which number CANNOT be the first term of the sequence?”</p>
<p>What about the period for that trig problem? y=tanX? I got π</p>
<p>@Nivers: 44 because 44 + 45 + 46 was over the sum, the rest were possible</p>
<p>@MM period was pi</p>
<p>Do u guys remember the other options for the horizontal asymptote one?</p>
<p>Yeah, period of tanx is pi. Even if you didn’t know that by memory, you could just look at the graph (assuming you knew what periodicity was).</p>
<p>@mmorkous</p>
<p>Yes the period was pi</p>
