<p>(x)(x+1)(x+2) is divisible by 2 and 3, not 4.</p>
<p>Rustgust-</p>
<p>You are correct.</p>
<p>@rustgust yep, x^x was approaching 1. they were tricky…b/c if u viewed the calc to only 2 sig figs, u wouldve thought it was 0.8 and not 1…</p>
<p>@ rust: i just did 0^0 and got one</p>
<p>@rustgust confirmed.</p>
<p>oh for the ln x = e^ -x…was it 0.27?</p>
<p>@ daboomps
Gah, I knew that!</p>
<p>For the graph shift one…</p>
<p>f(x) = f(x-2) + 3</p>
<p>is shifted two to the right and 3 up, correct? Does anyone remember what #46-49 were? I skipped three.</p>
<p>i’m with kjw…i know i got it right but i don’t remember (8,12). can someone just explain that answer please? or the question or anything?</p>
<p>@member and luminouzz
yes.</p>
<p>@Luminouzz
Yiezz</p>
<p>praying for a decent curve…im surprised there were no vectors…a lot of trig though</p>
<p>Anyone know when scores come out?</p>
<p>Also, for consolidations’ sake, I guess, I remember that question where they gave side AB in a triangle as 10.2 and the angles were 30 and 50 (and the one you can get on your own is 100, obviously) and they asked to find BC.
What I did was law of sines: I hope I remember correctly, but I did
sin30/BC = sin50/10.2
BC=10.2(sin30)/sin50
Which is 6.66. Or 1.56, if I screwed up the order of the sines.</p>
<p>Plus, yeah, I remember getting (8,12). My solution was:
2√13=√(x-4)^2+(y-6)^2
(2(√13))^2=(x-4)^2+(y-6)^2
52=(x-4)^2+(y-6)^2</p>
<p>I just plugged and chugged until I got to (8,12):
52=(8-4)^2+(12-6)^2
52=16+36
52=52.</p>
<p>YOSH.</p>
<p>Ok can someone please explain the following:</p>
<p>I put ln.27 in my calculater and get -1.309 and e^.27 in and get .76, for every decimal less that 1 I enter for x I get a negative number for the ln x and a positive number for the e^x, doesnt that mean 0 is the only number that works?</p>
<p>You screwed up the order rust lol, It’s segment over sine, srry.</p>
<p>AH! Another remembered question to add to the list.
This one was x=√(2+√2) and asked to find (x^2-2)^2.
Which is just:
x^2=2+√2
x^2-2=√2
(x^2-2)^2=2.</p>
<p>Also someone said thatif you have a line with 5 distinct points on it it can be divided into 10 segments why is that?</p>
<p>Does anyone remember about what # these questions were? Were they around 46-49?</p>
<p>1) series question
2) f(3) - f(1) question
3) angle made by lines</p>
<p>Also, was the parametric question = -1/3? I saw 1/3 earlier, but I got a negative.</p>
<p>hey, do any of you guys think that the curve will be at 43? because… apparently there was a question that had no answer or something…-_-</p>
<p>law of sines can go either way</p>
