<p>let me try to put the circle question to rest…
(x-3)^2 + (y+1)^2 = 25 was the original equation. the center is at (3,-1). if you want it to shift it 5 units right and 2 units down, the center would be at (8,-3). thus, the new equation would be (D) (x-8)^2 + (y+3)^2 = 25</p>
<p>^the equation is rite, but im not sure about the letter</p>
<ol>
<li>perfect cube question p^2r^5t^7 or something like that where p, r, and t are all distinct primes. dunno answer</li>
</ol>
<p>i got 3^9 x 5^9 x 7^9. not sure if thats the lowest though :[ im hoping</p>
<ol>
<li>Arithmetic sequence: started at 1, kept on adding 7, answer was something like 92?</li>
</ol>
<p>i got something in the seventies i think</p>
<p>we shud be trying to complete the list guys, our memory will fade soon =/</p>
<p>okay i agree with you physicsboy32 about 17, but if you go back someone else put an explanation with a different answer i still am not sure.</p>
<p>HUBRID:
The center of the original circle was (3, -1). If you shift it 5 units right and 2 units down, the center changes to (8, -3), which gives (x-8)^2 + (y+3)^2 = 25. If the question said 2 units up, then the new center would have been (8,1) and your answer ( (x-8)^2 + (y-1)^2 = 25 ) would be correct. Can someone confirm it was DOWN 2, not UP 2?</p>
<p>it was down 2 confirmed. </p>
<ol>
<li>f(x) = 1/(x^2+2) For which value of x is f(x) closest to 0.01. That one has two correct answers! Both 9 and 10 give pretty much the same answer.</li>
</ol>
<p>the answer was 10. confirm?</p>
<p>Is there a fast way to do the aritmethic sequence one? I simply kept adding 7 on my calculator until I got all the answers 
But I felt dumb.</p>
<p>yes, answer was 10 for that one</p>
<p>I put 10 too but the difference between 9 and 10 was like 0.000002 ***</p>
<p>im wrong about the cube one. I did it on my calc and got a number.999999. during the test i just saw the decimal and eliminated it… im stupid ._. .999999999 = whole number so previous poster was rite</p>
<p>just double confirming 10 is rite</p>

<p>i did the same way</p>
<p>does anybody else have an idea for the graph of the -abs(f(x))? i put the one that was entirely below that y-axis and exited in the 3rd and 4th quadrants… which i think was choice B. im sitting at 2 wrong and 3 omit right now, so this is the question that will make me or break me</p>
<p>chopstick, i put it entire below the y axis</p>
<p>because the absolute value makes it entirely above and then the negative switches all the y values below the x-axis. that was my logic</p>
<p>^ yep. just hoping someone has a definitive answer</p>
<p>my raw is sitting at a 44 rite now D;</p>
<p>the clock at my room wasn’t working. ***. there was a working clock behind the broken clock they put up, and they wudn’t take down the broken clock. ._. I also got the answer to the last 1, but was sitting rite in the front and the test just ended. such bad luck lol</p>
<p>Do you guys remember this question? sin x < cos x
was the answer 0<x<45</p>
<p>yes i got that</p>
<p>wait… i think i put <= 45. was there also a < 45 choice??</p>
