<p>question about -1<=x<=1 and -1<=y<=1 is pi/4, who remembers if that was C or D</p>
<p>sorry to keep posting it but i really need to know and hopefully someone whose looking at it does</p>
<p>@Rishab C297 which did you leave blank</p>
<p>x^2+2x+4=(x+2)^2+a(x+2)+b</p>
<p>if x = 0 then it would be </p>
<p>a+2b = 0 so then how did u find a to be -2</p>
<p>habesha: probably cause rather than guessing, if he gets it wrong by guessing it will hurt him more than just omitting</p>
<p>also for the babysitting problem did u get a</p>
<p>@ders12:</p>
<p>x^2+2x+4=(x+2)^2+a(x+2)+b
x^2+2x+4=(x^2+4x+4)+(ax+2a)+b
x^2+2x+4=(x^2)+(4x+ax)+(4+2a+b)
x^2+2x+4=(x^2)+(4+a)x+(4+2a+b)
so 2x=(4+a)x → 2=4+a → a=-2</p>
<p>i didnt know how to do babysitiing question. what was the answer</p>
<p>@jimjones: (32.5-2x)/3.5</p>
<p>What babysitting question lol I dont remember that</p>
<p>oh poopy… 4 omit andd 2 wrong so far. thats 800, but if i get more wrong im screwed</p>
<p>@Hiking7610 do you know if that was ans choice B?</p>
<p>also this is the same test as November 2008 js</p>
<p>@rishab: no idea what answer choice babysitting one was.</p>
<p>I skipped 8. I’m screwed.</p>
<p>omg ur right … -.-</p>
<p>There’s always next time. If I learned anything from today, it would be, don’t get too comfortable with the collegeboard practice tests.</p>
<p>Anyone want to predict the curve? </p>
<p>I omitted 7 and got at least 1 wrong, I’m dead</p>
<p>poster- thats like 790</p>
<p>I said AT LEAST 1 wrong. </p>
<p>I will probably end up between 670-730 :(</p>
<p>i was looking at the nov 2008 thread and a kid got a 780 with 9 omits to give a reference point, </p>
<p>any estimate with 0 omits and a range of 5-8 wrong</p>
<p>ders, thats 770-800</p>
