<p>f(ab) = f(a) + f(b)
f(16) = f(4*4) = f(4) + f(4) = 24
the one with the n(n-3)/2 I put 65… did quadratic and got n = 13 and then I checked all other answers…</p>
<p>yea i think this math was not to hard but i think it was just design bad >.></p>
<p>susannach, the answer was 65 on that q right?</p>
<p>65 is correct ;D</p>
<p>f(16)=f(4x4)=f(4)+f(4)=12+12=24</p>
<p>yea i think this math was not to hard but i think it was just design bad >.>
^
ditto…</p>
<p>How are you guys doing overall?</p>
<p>So far for me:</p>
<p>-2 M
-1 or -2 CR
-0 W</p>
<p>kind of off topic: are we allowed to use programs weve programmed into our calculators? like for example quad formula?</p>
<p>i guess if u dont get caught ;D lol</p>
<p>No, it was not guess and check.</p>
<p>2 f(x) = F(x^2)</p>
<p>f (4^2) = 12 X 2</p>
<p>f ( 4 ^ 2) = 24.</p>
<p>Of course, one would have to recognize immediatly the 16 is the square of 4 before this is pratical… took me 7 minutes to figure that one out.</p>
<p>
</p>
<p>Dang, it’s so simple once you see it.</p>
<p>I got thrown off because I started off with f(64) = 12 + f(16) and tried to do something with that…</p>
<p>-0 M
-4 CR
-3 W </p>
<p>I dunno for sure… there’s still a lot of debate on the CR questions… I hope I didn’t do something stupid, like missbubbling, or not erasing clearly enough :/</p>
<p>Someone should definitely complain about the citrus question to CB :P. I’m angry</p>
<p>yea most of the questions got me thrown off at first tooo cuz we thinking to much</p>
<p>CR: If I get a 500, I’ll jump for joy. forever.
M: I am hoping for at least a 600
W: I think around a 600</p>
<p>Susannach, (-1,1) is correct.
Xatuutuax, I got all the same answers as you! :D</p>
<p>Also, for all those people that had two grid-in math sections, the one with the triangle(x,y,a,b) is the experimental. (and the answer to the triangle problem, #13, is 142)</p>
<p>for me i hope i get a 1270 m and r total lol im hoping for a 560 on reading but i doubt since i left 12 blank >.> math hopefully 730+</p>
<p>umm wat monoclide?</p>
<p>When do results come out? (sorry, I guess this is a bit offtopic)</p>
<p>what did you guys get for the one with like 4 intersecting lines and it was u+w+v = 330 and it asked you to get the sume of u+z+x or something like that? I got 210…but I have no idea</p>
