<p>@stevenydc It’s easier to do if you draw a triangle, but not necessary. To find the length of the hypotenuse, use sqrt(a^2+b^2), so you get sqrt(4+k^2). Since sine is opposite over hypotenuse, it was k/sqrt(4+k^2)</p>
<p>YES I PUT III ONLY FOR THE LAST ONE</p>
<p>Another answer was 0 or 2/3
i forget the question</p>
<p>ahhh…yeah some how i thought acute means angle bigger than 90…</p>
<p>Re: n^k question…</p>
<p>Didn’t the question ask which number n could make n^k divisible by 180?</p>
<p>@cortana431 - Yea I recall “0 and/or 2/3” being an answer too</p>
<p>@Daisie - Yes it did, the answer was 30.</p>
<p>Does anyone remember what # 49 was exactly? It said that if the number was even then the term was 2?</p>
<p>@cortana: At which points does f(x)=? equal to 1</p>
<p>For the last one I is correct too right? Why would the third plane not be able to intersect the other two planes?</p>
<p>@Rennir I got 0 and 2/3 for that one.</p>
<p>what was the question in 49?</p>
<p>Thanks, btbam1.</p>
<p>Alex,</p>
<p>If n was odd, the nth term was the remainder of n/7. I got 12.</p>
<p>EDIT: Oh no!!! 12 is even!!!</p>
<p>isntthat ^k one 6? 6^6 =36, 36x5=180
i mean 6^2</p>
<p>@Daisie: I thought it was the other way around…does anyone remember the exact wording of that question because it definitely wasn’t “divisible by 180”. I thought the wording was rather confusing for that one…</p>
<p>Also, it’s not 12 because it said even terms=2</p>
<p>I got 2 different answers for the last one, I think I and III. It said what COULD, so it doesn’t have to work all the time.</p>
<p>What about the one where it said all test scores were increased by 5 or whatever? I put standard deviation.</p>
<p>@xAlex452 - Something along the lines of…</p>
<p>“In a certain sequence, if the term n is even, it is equal to 2, if it is odd, it is equal to the remainder when n/7. What term n is equal to the 5th term?”</p>
<p>The choices were:
a) 10
b) 12
c) 19 <- The correct answer
d) 21
e) 35</p>
<p>10 and 12 are even - and thus ruled out
19/7 and 5/7 have the same remainder
21 and 35 are both divisible by 7</p>
<p>But the remainder of 5/7 isn’t 2 is it? The remainder of 7/5 is 2. I can’t remember if i put 19 or 12 ahh!!!</p>
<p>@Rennir: Their wording sucks.</p>
<p>could someone explain the “0 or 2/3” i put 2/3 in and it wasn’t right.</p>
<p>@chewydog - I agree wholeheartedly.</p>
<p>another one was “what is the smallest integer n that divides n/2 n/3 n/5 n/9”</p>
<p>I got D for that one. E worked but D did also and is smaller. It was like 2 x 3 x5 x6 or something</p>
