ACT post-test

<p>it is no solution if its (x+y)^2 if i did the math right :)) so we r good on that one</p>

<p>good stuff, i'm still in the running for a 36 on math (haha i hope)</p>

<p>im worried about the enlgish tho cuz it seemed almost too easy it didnt really test anything important,, in fact i dont even remember having to rely on any rules AHHHHH</p>

<p>yea i never have missed a math ? on any test but the act always 800 on sat I And II but on my last act i was down to a 33 just because i got a 33 on math and a 31 on reading :(</p>

<p>lol, same here.</p>

<p>usually what i do, is like i read it to myself in my head, and replace the underlined portion with the way i would speak in real life... and that ends up working. so english usually isn't that hard, i don't remember having very many tough questions...</p>

<p>thats y im scared tho cuz if it seems to easy then it probably wasnt</p>

<p>just be confident, if you feel like you breezed through it, it may just of been an easy test for english, and there won't be as much of a curve.</p>

<p>yea who cares really i already got a 33 i just was tryin to get it to a 35 cuz thats what i feel i should be gettin, plus i need to make up for my 3.6 but
no need stressing out about it till scores r realeased lol</p>

<p>we can get scores in 2 weeks right?</p>

<p>i know sat scores take about 2 weeks so that sounds right but i heard someone say the 22 or 23 so thats a little sooner ;)</p>

<p>that would be great.... i am so anxious for scores....</p>

<p>December 20–22, 2005</p>

<p>Right off their website. Wow, that's next tuesday.</p>

<p>The conics equation is... infinitely many solutions</p>

<p>allow me to explain.</p>

<p>this is because (x+y)^2 = 10 and xy=3.</p>

<p>Expand: X^2 + 2xy = Y^2 = 10</p>

<p>Substitute: X^2 + 2(3) + Y^2 = 10</p>

<p>Simplify: X^2 + Y^2 = 4</p>

<p>This is a circle, which the graph was:</p>

<p>Circle with radius 2 on each side:</p>

<p>X^2 / 4 + Y^2 /4 = 1</p>

<p>The question asked: "how many REAL solutions are there."</p>

<p>Thus, there are an infinite number of REAL solutions. If it asked for integer solutions, there would've been none.</p>

<p>Hope this clears things up.</p>

<p>I got infinite also.</p>

<p>Does anyone remember the last science passage with the two scientists/students? P1 dissaproved student 2, right?</p>

<p>Oh wow. Now that I think about it. It is no solutions... yikes.</p>

<p>I discounted the fact that xy=3 for the other x and y variable.</p>

<p>I put no solutions on xy=3 (x+y)^2=10. What did everyone get on the one that used the law of sines? I put 71 i think.</p>

<p>it says that multiple-choice will be available on Dec 20-22 but for the writing do you have to wait until they send it in the mail??</p>

<p>and i also remember their being 6 events and the 1st and 6th were known. i put 1/24 for the answer.</p>

<p>I got infinite.</p>

<p>and I got 1/24.</p>

<p>Does anyone remember the last science passage with the two scientists/students? P1 dissaproved student 2, right?</p>

<p>i just graphed y=3/x</p>

<p>and y= +-10^.5-x</p>

<p>because i didnt trust my algebra skills</p>

<p>no intersections</p>
