<p>for the one that had exactly 2 real roots was it (x^2-something)(x^2+something)=0
I think answer choice c, can’t remember… because I filled it in last second, lololo</p>
<p>Yeah, that’s right hookem168.</p>
<p>was the solution to a conic (2,-3), (-2,3), or something similar? </p>
<p>@INVENIAMVIAM:</p>
<p>“800 - 10(44-raw)”, meaning Scaled Score = 800 - 10*(44 - RAW)</p>
<p>it’s from the barron’s book. google isn’t turning up other charts the convert raw to scale score, but (i guess this only applies to me) a raw score of 26 equates to 620 via barron’s, 640 from PR, and 610 kaplan</p>

<p>pvtejasvi, “I omitted 8 and probably missed 2 - is that over a 700??”
safe to say that will be mid 700s</p>
<p>to solve the compound interest one I used the fact that of course ETS would put in the answers for (35)(1.05)^4 and (35)(1.05). I chose the one in between those two.</p>
<p>Pvte- that is probably a 750-780</p>
<p>^^Yeah… I’m pretty sure it was one of those two, otrebmu. Can’t quite remember which value had the negative, however.</p>
<p>someone earlier was talking about the the one where x = (some quadratic equation). but when you divide the x over, it is no longer a quadratic equation, so there cannot be two roots.</p>
<p>therifleman…all you do is compound it quarterly, so:</p>
<p>starting amount x (1 + rate/4)^(time x 4). I got 3800+ or something similar</p>
<p>You can’t divide x out of a quadratic, buddy…there’s a constant lurking at the end there lmao.</p>
<p>“Algebra EPIC FAIL” as my Physics teacher once told me :p</p>
<p>For that one I just imagined the line y=x and the quadratic y=ax^2 + bx + c. They can definitely intersect at two points…</p>
<p>what did everyone get on the parametric equations one?</p>
<p>I put E (possibly D, somewhere at the bottom lol) because it was an inverted parabola (-x^2), but there was a translation up 1, and when you plug in (x^2 + 1) as the x value, to invert, you have to make the constant negative. W/e I’m not making any sense haha</p>
<p>what was the the answer to the range problem that had a downwards parabola in the 1st quadrant?
also, there was an upwards parabola that asked for points or something that’s solutions was 0,1,2,3 infinite?</p>
<p>was the answer to the compound interest problem not:
X>store>1.052
3500*X
ansX
ansX
ansX
=4286.778</p>
<p>I put the answer where the t equaled the negative X^2 term, with the minus one on the end.</p>
<p>range was all real numbers less than or equal to 2, the limit of the parabola at x=whatever was infinite if I remember correctly</p>
<p>Same, iwaswalking.</p>
<p>same for both, inveniamviam.</p>
<p>Your SN piqued my interest! Did you happen to take Latin today as well?? My friends said it spanked them…</p>
<p>hookem168:"therifleman…all you do is compound it quarterly, so:</p>
<p>starting amount x (1 + rate/4)^(time x 4). I got 3800+ or something similar"</p>
<p>oh wow. so what i did was flat out quarterly interest rate… makes sense now</p>
<p>yeah, you just gotta remember that word compounded.</p>
<p>^come down brohamut</p>
<p>lol. otrebmu, u are screwed</p>
<p>^ BigWeight, be sensible. Just because he mildly effed up a single problem doesn’t mean anything about his chances as a whole. Otrebmu, keep the faith, sir!</p>
<p>
^lol, yep took Latin, it spanked me a lot harder, I bet. lol. SUB 700!!! ahaha probably</p>
