<p>does anyone remember getting 33 as an answer? lol pretty vague but…</p>

<p>Yes. I do!</p>

<p>Thanks so much Frontium!</p>

<p>I definitely remember that one now, and I am sure that I got (9,0).</p>

<p>What was 33 an answer to?</p>

<p>whats 3/4 of 3/4</p>

<p>@miami</p>

<p>(3/4) times (3/4) </p>

<p>= 9/16</p>

<p>What was 33 the answer to???</p>

<p>what was 33</p>

<p>for the area of the triangle problem the answers were like A) 6 B)7 C) 10.5 D) 16 it was c right</p>

<p>I just put the formula into excel, calculated it for the first 20 numbers, and it approaches 0. Please, let’s not bicker over this! I think what some people may be thinking is that if you keep adding numbers into the sequence what will the sequence approach, which would obviously be 1. But you have to multiply. Ergo, 0.</p>

<p>Do you guys remember getting 140 degrees for one of them?</p>

<p>@nbasuns, wasnt that question in like the first 10 problems?</p>

<p>What was 33 the answer to?</p>

<p>@nbasuns2: Possibly? I don’t usually remember exact numbers for answers or questions but if you can re-create the problem (feel free to use fake numbers–it’s the concept that’s important) people–including me–will be able to help you better.</p>

<p>@miamiheat305: If you remember the problem why don’t you help out instead of passive-aggressively insulting nbasuns2 for not understanding an early problem? And if you were talking about the ramp problem in your earlier post, the exact answer was 6(1.75) and the answer to the question was the closest option to that.</p>

<p>@redditor13: That’s exactly what I did during the test on my calculator! Haha. Once I got to 0.07 or something and realized it was steadily decreasing I just put in 0. I actually recognized the problem as a product sequence but I was too lazy to do it the fancy math way. And because I knew that if I needed to use anything beyond trig I was making things more complicated than they needed to be.</p>

<p>Regarding the multiplying fractions problem:
The proper and unnecessary mathematical notation for the multiplying fractions problem it would be <a href=“http://■■■■■■/4sj7P[/url]”>http://■■■■■■/4sj7P&lt;/a&gt; but the only difference between that and what was actually written on the test is spelling. The math behind it is doable with math knowledge up to trig, but difficult because most have never seen a similar problem before.</p>

<p>@nbasuns2: Yea I remember putting 140 degrees down for that problem. I’m not sure if it that’s right as I fail at geometry. The problem showed two parallel lines and a line through the middle asking for an angle.</p>

<p>Do any of you remember what the exact problem was where 140 degrees was the answer? I don’t recall getting 140 degrees as an answer and I don’t know if it’s because I got a different answer for that question or if I just forgot.</p>

<p>@ wrcurly- Oh my god will you please shut up?</p>

<p>It was a geometry problem. There were parallel lines with a line intersecting them. I believe there was a right angle somewhere in it too along with a given angle of 130.</p>

<p>@miamiheat I know it’s an easy question. I was just trying to get more questions out in the discussion.</p>

<p>Yeah it involved two parallel lines and basic angle geometry. I’m also confirming that 140 degrees is correct.</p>

<p>Okay, so I think that I have proof (or as much as we will get) that the answer is 0. </p>

<p>In the problem, it said that x had to be greater than or equal to 3. For them to include that in the problem if they were only wanting to know the last number or the product of the last 2 numbers of the sequence as x increases would make no sense since it would be irrelevant. </p>

<p>HOWEVER, it would be absolutely necessary for them to include it if they wanted you to take the product of the entire sequence because if they didn’t, you would get one fraction that had a 0 in the denominator which is undefined, making the problem impossible.</p>

<p>Bump… Thoughts?</p>
