December 2007 MATH level 2

<p>or maybe they were both neg as sillbill said, but either way the one with 13pi I believe</p>

<p>That polar one was the only one I skipped >< Gah I thought it was easy, but now with all these replies I'm beginning to think I made some dumb mistakes.</p>

<p>By the way, if say a quadratic graph's formula is f(x), then how would f(x-4) change the graph?</p>

<p>Does anybody remember the length of the diagonal of the parallelogram??
I really need this answer people!!!</p>

<p>no it was (1, 13pi/4) sigh, i actually think that's the answer anyway</p>

<p>30 somthing..</p>

<p>anjoola, the graph moves 4 to the right, so the answer was B</p>

<p>@ Anoola...graph is shifter 4 units to the right...</p>

<p>@anjoola: it would move 4 units to right..</p>

<p>wot was the answer to the last ques...??????</p>

<p>@Pinki and Math </p>

<p>Oh great, that's allright. Cause I remember some problem on a practice test in which f(x,y) was a quadratic and f(x^2,y) actually made it a sideways parabola O_o</p>

<p>@Math for parallelogram </p>

<p>Remember parallelograms have complementary angles. So if one angle was (not trying to say any test problems since I signed the thing) 115 the other would be 65 and you'd do the law of cosines.</p>

<p>i just wished i had reached there lol</p>

<p>at anjoola..Yeah, i used teh law of sines instead</p>

<p>I don't remember the ques.. But there was some ques which had to be solved using law of sines... right..???</p>

<p>wait didn't the diagonal question ask which answer was the BEST estimate? i got 32 put i picked 34 coz that was the "best estimate" of all the answers.</p>

<p>i used law of sines, btw. i used law of cosines for something with a degree of 106.</p>

<p>@rashi
Yeah there was a question about parallelograms except with different numbers (don't want to break that contract)
I THINK there was one with sines I'm not quite sure...</p>

<p>What was the answer to the one about finding the area of the triangle?</p>

<p>even I wanna know the answer...</p>

<p>@SillBill
Was that the one with a double triangle? Like there was a big one and a smaller one was drawn in it?
I forgot, but I used the law of cosines and law of sines.</p>

<p>BTW for the trapezoid one, the one w/ a graph of log, was it 6?</p>

<p>And how come everyone takes the math exam? O_o just a weird question cause everyone in my testing center was taking math.. coincidence?</p>

<p>yep thats what I did...another way you could do this ques quickly was...
the 2 sides are 29 and 27 units..From the diagram, teh diagonal looked slightly, not alot, bigger than the sides...
options more than 29 were 34 and 42...and 34 seemed like a good bet...ofcourse to be completly sure, you had to use one of teh laws</p>
