<p>Quick question, for the problem that was (x+3)(x+5)> (I’m unsure of the sign) 0, was it x=-6 or was it x=-4?</p>
<p>chkw94:
Are you joking?
A decreasing slope can still be positive. The y-value obviously kept growing, but the slope was clearly getting smaller. (on my problem, at least)</p>
<p>Also, it wasn’t a line. It was a curve. Hence the slope changing.</p>
<p>i agree with “otherwindow”</p>
<p>by the way,what did choose?otherwindow.</p>
<p>Azhong, it was -6 I’m pretty sure.</p>
<p>Also, can someone refresh my memory on the specifics of the knitting question(I’m trying to remember which section was my experimental, I’m only sure it was math).</p>
<p>We mustve had different questions… It was a line y=mx+b with positive m (slope).</p>
<p>What do you guys think the curve will be for math this year?</p>
<p>i know the slope is positive,but the slope is increasing at the “decreasing rate.”</p>
<p>I give you an example,the car is driving ,but is’s slowing down.
Same here,the car is driving at the positive speed but at the “drecreasping rate.”</p>
<p>So,the slope is decreasing,but it’s still positive number!</p>
<p>That is why i talk about calculus.
I m not trying to confuse u guys,but tat is waht i want to say.</p>
<p>That was, like, question 5… why would anything remotely related to Calculus be involved in an easy question like that…</p>
<p>haha,ok.~~~~~~~~~~:D</p>
<p>It was a graph. That you looked at. Like honestly, guys, even I got that one! :P</p>
<p>I put 5200. TBH, it’s probably wrong if others that say 5700 with the same question. </p>
<p>And tenors, it def. didn’t require calculus, you just had to notice it wasn’t a line. I recall it being a question mid-way through the section also. </p>
<p>Who knows; we’ll see when the scores come out, I don’t want to stress over a question like this for the next 18 days!</p>
<p>haha.u r rite.otherwindow!</p>
<p>Yeah, putting 5200 I can understand (I’m pretty sure I’m right; I like quintuple-checked that one), but I really don’t see why we have to keep debating and keep debating it. There are two possible answers. One of them is right. 5700 is the consensus. Now let’s shut up for 18 days. Haha.</p>
<p>does anybody remember the question about the circle with a 45 degree angle? were you supposed to find the length of the arc AB or the area of the shaded section. apparently i might have read through it too fast…</p>
<p>@nymets</p>
<p>I think it was area.</p>
<p>I’m pretty sure it was arc length. =/</p>
<p>…wait…</p>
<p>did you guys get a fraction as the answer?</p>
<p>That answer was 3pi
Radius was 6, meaning circumference was 12pi. 90 degree angle made it a fourth of 12pi, or 3 pi.</p>
<p>I remember a 3pi arc length. I don’t think it was shaded though. Different question maybe?</p>
