<p>^^ (-2, 5) and tan x.</p>
<p>the question about the populations of summertown and another town where it asked for how many times they had the same population, did you just graph it?</p>
<p>^ nehccire
Yep. It was 6.</p>
<p>(and the the other town was cooltown!)</p>
<p>Does anyone remember what the last question asked off the top of their head? I forgot if I answered it correctly, though I recall it looking pretty easy.</p>
<p>Easy? ***???</p>
<p>You guys said the answer was (-2, 5) for the center. Was that A B C D or E?</p>
<p>I thought this test was extremely hard. I didn’t study because I felt confident about it, but gah, I definitely failed that.
I wasn’t able to graph the -2100 thing. . . it wouldn’t work.</p>
<p>Is there a consolidated list of answers?</p>
<p>(-2,5) was choice A I think. The other four had two choices with x=2 and two with x=5.</p>
<p>The periodic one was -1, right?</p>
<p>I am thinking -7=800? Anyone agree?</p>
<p>Can someone explain the periodic one? Aka the last one? :(</p>
<p>Since the graph had a period of 3, it should return back to -1 after three points. Since a-1 = -1, then a+2 should also = -1. But I may be wrong…</p>
<p>What was the three dimensional one with the points 0,0,5 and 0,0,-5?</p>
<p>Edit: nvm: z=0</p>
<p>Ah alright, I overthought that then. Phooey.</p>
<p>morpheus44, it was z=0.</p>
<p>Did anyone else think it was interesting how some questions like 50 were super duper ez(-1), while others required a lot of time?</p>
<p>Does anyone remember what the parametric question was?</p>
<p>I thought the test was incredibly hard.
The question that included the (2,5)s I had no idea, so I tried substituting all the values into the equation and none of them turned out to be 0! So I guessed A, which you guys said is right.</p>
<p>I didn’t know how to do standard deviation.
Or that average speed one - the 80 km/hr and 60 km/hr, when the whole trip is 240km?
I think I guessed D, because I “narrowed it down” to C and d?</p>
<p>For the average speed/train one, I just made t (# of hours) a random number, then did guess & check with the answers till one worked out.</p>
<p>For the one with 3 rectangles and the ln curve, was it 21? And I think D for 60 & 80 one but what were the choices??</p>
<p>Hardworking21 -> for the ln (x^2) curve i got 21.01, yes :)</p>
