<p>there goes my 36. great.</p>
<p>hmm it was 30 dollars per small and 70 per large…so thats 180+140=320</p>
<p>whereas 70 times 8=560…pretty sure it was 0 smalls and 8 larges</p>
<p>DD says O smalls and 8 larges.</p>
<p>i used a horrible calculator …might have screwed me cuz it always took a lot of effort to type in and wouldn’t register every button i hit
…darn</p>
<p>ti89 < 3</p>
<p>I’m pretty sure it was all large too.</p>
<p>hmm i’m still not so sure a/b the triangles having equal area…i dont think that the sin of the triangles came into play in the way ur claiming</p>
<p>Wow.</p>
<p>I love how the 3 questions everyone is discussing are the only 3 questions I had trouble on.</p>
<p>The two triangles one - I said 30…</p>
<p>The x^2 + mx + n one - I had NO CLUE. I thought it was impossible… I guessed -3 then changed to 9…</p>
<p>The maxed out one - It was all larges, 560 or something, I’m sure of that.</p>
<p>One other question:</p>
<h1>of lines of symmetry - 8?</h1>
<p>I got all larges but I may have missed the area/triangle question…I either put 30 or 25. O well, I got a 35 on it b4 and Rice superscores the ACT = D.</p>
<p>I got 16 lines of sym…for the sequence sum question wat did u get?</p>
<p>ok, good. what was the one about m and n towards the end? did anyone just plug in -3 and then see what values for that variable could work? i have a feeling i did it wrong.</p>
<p>was the determinant question 4? i forgot what a determinant was…
anyway, thats what i put</p>
<p>thats wut i did chair and i also got 16 lines of sym</p>
<p>yes, it was 4. and the lines of symmetry was 8.</p>
<p>im pritty sure it was 16…cuz I drew 16 and they all worked</p>
<p>you can’t just count each vertice to be a line of symmetry because one vertice’s line is the same as the one opposite of that one. so i think it’s 8.</p>
<p>The two triangles should have the same area (30). I don’t know how I did it, I just mentally saw the two triangles ahd squished the 110 degree one and it became the 70 degree one haha</p>
<p>Yay, I put 8 too!</p>
<p>I put 8 larges.
and the area was 30 I think for the 110 angle using heron’s formula or some obscure crap i learned in precalc. </p>
<p>and then for the x^2 + mx + n where x could only equal -3, the answer was 6 because if you separate it out, the equation factors into (x+3)^2… if you multiply that, you’ll get m = 6</p>
<p>I know…I physically drew them all and counted them and each “vertice pair” I only counted once. There were some lines other than directly through the vertices. Anyone else have any thoughts on this question?</p>
<p>The m question was 6, right?</p>
<p>I thought it meant that it was just (x+3)^2, and expanded it’d be 6?</p>
<p>Was the x^2 + mx + n question -6?</p>
