<p>What did you guys put for the one that asked for AC in terms of k? They gave you a triangle, it said that Angle A was 90, AB is 6, BC is x. I got like the root of 9-(3/k)^2</p>
<p>I remember another one that ask for the absolute value of y, it was really easy.</p>
<p>^do u remember the perimeter question?</p>
<p>guys what was the answer to the last problem that said something like if it increased from 1million to 10million, how long would it take from 2million to 20million or something? the last question… what was the alphabet?</p>
<p>The perimeter question was easy… make the larger triangle into 2 triangles…</p>
<p>vertex angles were 42 degrees and base was 25cm</p>
<p>so find what the 3rd angle is… now you have a full angle but just one side…
now to make it easy, cut the triangle in half and you should have two similar triangles with angles 90, 42, 24 and a base 12.5. </p>
<p>Find the hypotenuse of the “smaller” triangles and multiple that hypotenuse by 2 and add 24.</p>
<p>@winston94 It was 8 years… i think it was B or C not sure though</p>
<p>^ I am talking about the isosceles triangle one…</p>
<p>@king idr answer, but since you had the angles you could use law of sines</p>
<p>@ellan yah that is what I used but some people said the answer was 60 something so i got worried</p>
<p>Wait are you guys really saying that r=cos(ø) in polar?
Conversions are without a doubt:
x=rcos(ø)
y=rsin(ø)
r=sqrt(x^2+y^2)</p>
<p>It aksed for the polar corrdinates</p>
<p>What would a score of 6 omit 0 wrong be? How about 6 omit 1 wrong?</p>
<p>Sent from my SCH-I500 using CC</p>
<p>What would my score be if 2 omit and let’s say 6 wrong</p>
<p>@ Joshi13 790-800, depending on curve. usually, 800 cutoff is 44, but this test could range down to a 43 or even a 42 (I hope the latter since I had a raw score of 42 
)</p>
<p>but your 43 could be 790…then again could be as low as 780…most likely 790 tho</p>
<p>@KyleGC thats a raw score of 41, so probably 770 or 780, depending on curve</p>
<p>^ isn’t the curve probably 43 cutoff??</p>
<p>Anything above 750 would be awesome but I always mes more than I think :(</p>
<p>@king as far as i’ve heard, 44 is, but if the curve for this test is lenient, then prob 43.</p>
<p>what is everyone’s opinion about the curve?</p>
<p>also, if you guys remember problems 1-35, please discuss as we all want to get peace of mind about possibilites for careless mistakes (which usually crop up in the first half)</p>
<p>@tiger do u remember the one with the perimeter of the isosceles triangle with a base of 25??? Was it 84 something??</p>
<p>@Vyxl: No, we know the conversion. In the question, we were povided with the relationship r = cos(theta). </p>
<p>Also, for the isosceles perimeter question, how many of you got something around 67? Remember, there may be two different forms, so don’t freak out if you thought the vertex angle was 50 or so.</p>
<p>@King i agree with studious about the isosceles, however, i think we had the same form: I definitely got 84 something</p>
<p>also, can someone explain how to do the steam and leaf plot? I feel like an idiot for having to skip it (it was only number 8) but I just cant remember how to do those! :S</p>
