<p>yayy
did anybody get the “at how many points does the xy^5+2y=3x-x^2 curve intersect the x axis?” or something like that O_o</p>
<p>I said one…I had no clue what was happening with that one haha.</p>
<p>What was the one with the point within 6 of a plane them something 12…hehe SAT has killed my brain</p>
<p>for that one i put like 113 or something
it was either that or 4something</p>
<p>Two: plug in 0 for y, and move the x’s to one side. You get (x^2)-2x = 0. Solve for x, and you get two roots, which are the two x-intercepts.</p>
<p>@Corey91: There is a circle of points on the plane within 12 inches of point P. Make a right triangle: 6 is one leg and 12 is the hypotenuse. Use the phythagorean theorem, and the one leg is the square root of 108. Square it and times it by pi, because that leg is the radius of the circle of points that point P touches. Answer should be 339ish.</p>
<p>I knew it had something to do with that but my brain just couldn’t figure out how it worked. Anyways I guessed that number, it was the one in the middle ^.^</p>
<p>I thought this exam was wayyy easier than the practice tests. And I was really nervous that they were going to put something on the test about vectors or matrices, like they say in the Princeton Review book. Thank god they didn’t, because I have no idea.</p>
<p>i know, unfortunately vectors and matrices were the topics i spent the most time on reviewing…=</p>
<p>also i couldnt seem to get the question with 4 digit numbers where 3 is followed by 2…=</p>
<p>anybody got the answer to the last one?</p>
<p>the 4 digit number thing was 6</p>
<p>answers anyone?!</p>
<p>Yeah. it was 6
1234
1423
2314
2341
4231
4123</p>
<p>I got 6, I did it by hand just to make sure</p>
<p>@Sciencegurl: what was the last one?</p>
<p>Lolloll. I skipped 7, and guessed on about 3 or 4. </p>
<p>I guess i’ll be around the mid-700’s.</p>
<p>I dunno, I really didn’t care/study hard for this test. Cause…is there really that much of a difference between an 800 and 750 on this math II test?</p>
<p>It was like f(x/4) = some radical function
what was f(a/2)</p>
<p>i put D.</p>
<p>did anyone get 1/9 for a probability question</p>
<p>What was the answer to the graphs & standard deviation question?</p>
<p>I completely forgot what standard deviation was.</p>
