<p>Probably regular (-6 or -5=800)…</p>
<p>And last standard deviation is 99%?
any one reemember the question and answer?</p>
<p>i took the sunday test and there were a few that i was completely stumped on…for example x^2-7x+2 has roots s and t, what is the factor of s+1 and t+1 </p>
<p>honestly it was harder than i expected it to be so i came ill prepared, i think i couldve done better if i new shorter ways to solve the questions. if i do bad i can retake it right?</p>
<p>I now understand the radius question</p>
<p>I was thinking that when you were cutting the cone, you took the bottom half (which is some demented trapezoidal cylindrical shape) rather than the top, which is now a new cone</p>
<p>Whatever, nothing I can do about it now</p>
<p>I felt soooo stupid after that cone one…</p>
<p>This problem has caused me much pain… as every time I look at an ice cream cone… I remember it. hahah. No, but in all seriousness, was it in the Barrons book…that when you cut a cone it does this? Or was this just common sense (that I clearly lacked…)?</p>
<p>This was not on the SAT math level 2 test, but I figured you math whizzes could help me on these pre cal problems. I think it may be factor by grouping </p>
<p>a2 x2 - 6x-9 </p>
<p>2c5 +4c3+8c2+4</p>
<p>a^2-x^2-6x-9
a^2-(x^2-6x+9)
a^2-(x+3)^2
(a-(x+3))(a+(x+3))
(a-x-3)(a+x+3)</p>
<p>2c^5+4c^3+8c^2+4
2(c^5+2c^3+4c^2+2) [Do you have a typo here? The only way to factor here is GCF]</p>
<p>apcalc1 thank you so much :)</p>
<p>I don’t think there’s a typo… when I got to that problem on the test I was like *** because I couldn’t see how it could be simplified any further.</p>
<p>I just took the sat 2 math 2 and im really nervous. I omitted 4 problems and i think i got 6 or 7 wrong. Im shooting for a score hopefully above a 720, is this possible at this point? what do you guys think?</p>
<p>Also, i think people were talking about this earlier in the thread, but the last question on the may test was something like, f(x) is a periodic function, f(x+1)=1, f(x-3)=-3, whats f(x-2)? (i dont remember the exact numbers, but the question looked like that.) i said the answer was -2, because that seemed like the most obvious choice, but i feel like it was a trick question…did anyone else answer it like that?</p>
<p>anyone have a consolidated list? and i don’t remember the z=0 question? anyone remember it? and what was this about the periodic? i don’t recall the question.</p>
<p>z=0 one:</p>
<p>What is the set of points equidistant from (0, 0, -5) and (0, 0, 5)?
Answer: z = 0 (aka xy plane)</p>
<p>periodic one:</p>
<p>Function p has a period of 3.
p(a-1) = -1
p(a) = 0
p(a+1) = 1</p>
<p>What is p(a+2)?
Answer: -1</p>
<p>I missed both of these, that is why I remember them. :p</p>
<p>Would you guys saying that an average score for Barron’s practice tests in the 780-800 range is an indicator that I have a <em>very</em> good chance at getting an 800? Or is there still a decent chance that i’ll get less?</p>
<p>ahhh i recall those! lol for the z one, i think i just did the midpoint formula for the z point, was that the right way?</p>
<p>and for the period its just cause it repeats every 3 right? and therefore if you add one, its a new period and therefore its -1?</p>
<p>@mistervert, if you’re getting 780-800 on the Barron’s tests, I would be shocked if you didn’t get an 800 on the real one</p>
<p>I got a 650 on the Barron’s practice, then got an 800 on the real</p>
<p>Was getting 740-760 on Barrons with time being an issue, got an 800 with time to spare on this test. phew</p>
<p>Barron’s diagnostic: 610. Actual: 800</p>
<p>Barrons diagnostic - 780
Kaplan diagnostic - 740 ish
Sparknotes - 790
Real - 800</p>
<p>Just take a College Board Practice Test.</p>
<p>CollegeBoard Practice Score: 790
CollegeBoard Actual Score: 800</p>
<p>Not saying they are correlated, but hey, it doesn’t hurt to practice using instructions from the test makers (CB).</p>
<p>Barrons: 690-720
Real: 770</p>
<p>Barrons diagnostic: 610 real: 800</p>
