<p>did u guys get 1 for the question where two periods of a function was shown and it asked for f(100)?</p>
<p>anybody remember the length of the diagonal of the parallelogram? I bubbled 30 something</p>
<p>that works too, it's 8</p>
<p>Nick89 - I put 1/7 at first too, but then I realized that my signs were just messed up. 2 of the slopes were positive if I remember correctly (It was a sideways, kind of slanted triangle), so I knew that the slope had to be negative, since neg X pos X pos = neg</p>
<p>pink, i put it was zero but im not sure.</p>
<p>I guess even I did the same..</p>
<p>I think so pinki, it was the same as f(9) whatever that was (think it might have been one) since I believe the functin repeted every 7</p>
<p>yea...i got f(9) also. i think that was one</p>
<p>Pinki10583: I think that I got 1.5... It repeated after 7 numbers on the x-axis, so I just kept adding 7 on my calc until I got to like 104 or something like that... So I backtracked 4 numbers and it lined up to 1.5 on the y-axis... Did anyone else get the same?</p>
<p>@Pinki
"Y/(2x-y)=something and X/(2y-x)=?"</p>
<p>Its Y/(2x-y)=10, and its 11/29 like you put</p>
<p>But OMG i found that question so hard. At first i tried to do it algebraically with variables which took waaaayyy too long. So then I said to myself that CB would never set a question that couldn't be done in 30s so I just plugged in numbers for x and y to find the answer.</p>
<p>what was the answer to the paired gloves question?? it was like, what is the minimum number to pick out to guarantee a match? idk, but i put two. that question was weird though.</p>
<p>sillbill, that was the right method but you got it wrong since the function did not start at the origon</p>
<p>also wat was the answer to the counterexample question? </p>
<p>there was also a prime number question.....what was the answer for that?
i put 4 for the glove question</p>
<p>yea it was f(9). The function repeated every time x increased by 7 if i remember correctly.</p>
<p>Anyone remember the one about polar coordinates?</p>
<p>what DOES not points equal (1, pi/2)?</p>
<p>i chose (-1, -5pi/something) cuz it was the only one with negative and x and negative y value. Not sure at all though.</p>
<p>@artstar: i think the ans was 4.. it was definitely not 2 though..</p>
<p>dang! i was going to put four, but eh whatevs.</p>
<p>prime question was none (there is no formula to find primes). Not 100% sure though.</p>
<p>and for the gloves it was 4 </p>
<p>(BB GG RR) gloves, if pick out 3 you can get different pairs. Once u pick 4th then u have 1 pair. Sorry m8 but i think you're wrong.</p>
<p>@pinki: prime no. ques.. the ans was r+s+1... as 5+7+1=13 which is prime..</p>
<p>Yes, because if you pick three, you could get a red, blue, and green glove. Only when you pick a fourth glove are you -guaranteed- to have a pair.</p>
<p>For the prime number question, I also put none. 3 and 5 are prime, but 3+5+1=9.</p>
<p>@atomicbomb: there is no formula.. but the ques stated "could" be possible...</p>
