<p>For math discussion</p>
<p>I thought this section was a bit harder than usual, but nor harder than I had ever seen. I really started to run out of time at the end.</p>
<p>I had to guess on the triangle dots one, and I guessed the second largest number.</p>
<p>I had to guess on the one where you were given x^2+kx+17, and you were supposed to find k so that it would have two real roots. I think I just put down 16 or something.</p>
<p>I also had to guess on the system of linear equations</p>
<p>Last question. Was it A/F?</p>
<p>omgg… same
i ran out of time!</p>
<p>For k question, you had to graph it. I can’t remember the answer, but that’s how I got it.</p>
<p>What was the answer to the basic distance word-problem about this girl going from one destination that took 80 miles, to another location, and then finally back to her origin? It gave you the following ratio: 5:2:4, so what was the answer? Also with that triangle with the 68 and 58 degrees, they had answers like sin68/50=sin58/60, what was the answer to that?</p>
<p>For that question I plugged it into my quad equation on my calculator, the answer was -18 i think</p>
<p>I got -18 for the x^2+kx+17 one</p>
<p>@elevit you had to do 80/5 = 16 then 16x2 + 16x4 + 80 for the answer. I don’t remember the other one.</p>
<p>I believe the distance equation may have been 130, but I’m not sure if I’m remembering correctly. And the x^2 +kx +17 was -18. Other than using a calculator, you could have tried that answer choices and plugged in -18 and “backwards-foiled” the equation to solve for x.</p>
<p>for the girl one, I divided 80 by 5, and then found the value was 16. then you multiplied 16 by the other numbers in the ratio, and added it to 80. for that trig problem, I think it was b.</p>
<p>yes, I am thinking it was a negative number for that quadratic problem, I just guessed randomly. For some reason I just ended up running out of time and not being able to plug in the answers, as I skipped that question and came back to it at the very end.</p>
<p>@TedJones omg… i got it wrong
didnt even thought that problem was hard ■■■.</p>
<p>What did you guys put for the cube on in the beginning asking for the ratio of the smaller diag to the larger?</p>
<p>Hopefully it will be as nice of a curve that the act can have. maybe there will be room for one extra error somewhere around 34 or 35, and then maybe another one near 30.</p>

<p>The question about the inscribed angle, was the sum of the two angles 67.5 degrees?</p>
<p>I am pretty sure it was 45 degrees. this is because the inscribed angle behind the 90 is half of the central angle, so it was 45. if you split that shape into two it made two obtuse triangles with obtuse angles of 135. the 45 was divided in half. this means that each of those top angles is half of 45, making their sum 45.</p>
<p>yes, this section was harder than usual. How many questions did you guys think you got/ guessed on?
I had to guess on like 12 because of the darn time limit but i was sure about the rest. I think I got 50-51 right</p>
<p>I know I missed two, and there was one that I had to guess on and could have missed. overall, I think 4 or 5 wrong.</p>
<p>what was the answer to the dots one??? i picked the second biggest answer</p>
