SAT II Math Level Two May 2012

<p>Oh **** now i remember how to do them…f*** i could have got that easy point :(</p>

<p>@tiger, yah i think we definitely did have the same form… i remember the question as being 50 degree vertex angle and 25 base… i then proceeded with using the sin rule and used 65 as the angle opposite to the equal sides. In short, I had two 29 length sides and a 25 length base… aka… 84 something. </p>

<p>Perhaps there were two forms… :(</p>

<p>^ why are you sad about two forms? lol</p>

<p>hahaha cuz it makes it harder to check answers!!!</p>

<p>did the stem and leaf ask for the median? I can’t remember.</p>

<p>^I think so. Don’t remember what I got though.</p>

<p>yes it was asking for median. i put like 56</p>

<p>^ Yeah, that’s what I got.</p>

<p>@king oh tsk duh wow im stupid xD</p>

<p>but at least they dont seem too off…</p>

<p>OH GOD, I don’t remember the isoceles triangle problem…</p>

<p>wait i remember it now. and yeah i had 50 degrees as the vertex angle, not 42. East coast here.</p>

<p>^AWESOME!!! So you had 84 something as well!!!</p>

<p>i had 84 for answer, 50 was the angle</p>

<p>I’m pretty sure the stem crap thing asked for mean… Maybe 2 forms again?</p>

<p>My vertex angle was 42. There must be two different forms.</p>

<p>Edit: And my stem plot definitely asked for a median.</p>

<p>^ my vertex angle was definitely 50… are you sure you haven’t confused it with the one asking how many triangle could be formed? cuz that one had an angle of 42.</p>

<p>@studious I dont think we had different forms cuz mine asked for median as well, but apparently we had to different vertex angles…</p>

<p>I’m certain I didn’t get confused. I calculated 22 or something for each of the equal sides. 22*2 + 25 = 69 which is around 67. I used law of cosines. Also, someone could just be remembering wrong for the stem plot. Both forms could have been median.</p>

<p>Hey guys for the p^3 one it was II and III because the 3 distinct factors (not prime) are P, P^2 and p^3. For the triangle i eerily remeber my angle being 50 but I think I put the answer as 67. Was that even an answer choice? B/c the correct answer is 84 and studious maximus, even if you had the angle 42, you would not get 67.</p>

<p>Actually, I just ran the calculations, and I may have gotten that wrong. I can’t seem to get to my answer. With 50 degrees, I got 84. With 42, I got something around 95. I think I might have made a mistake. This sucks. Anyone want to confirm?</p>

<p>I guess that’s omit 3, one wrong. That’s still safe, so I’m not too upset.</p>

<p>Edit: p^3 has four distinct factors. 1, p, p^2, and p^3. So the one saying it has three distinct factors is wrong.</p>

<p>Edit: I got 84. 67 is not possible anyway you do it. used cos of lower right angle and solved hyp. mult by 2 and add to 25</p>
