<p>anyone know the center of the ellipse? i got (-2, 5) maybe that is right?
also got only II for that one problem, got 99 % for last, skipped the one about congruency.</p>
<p>i dont remember the number 5.35 but i do remember 8sin42</p>
<p>yeah, the last few questions got most people. And i think you’re right about the (-2, 5), cause you had to complete the square.</p>
<p>^^^nigcrunch, I used Barrons and it totally overprepped me but when it was time to take the real test, it was easy</p>
<p>How did you answer the ellipse question? That was the only one I skipped because I wasn’t sure how to do it.</p>
<p>same, i used barron’s as well, their test preps are ridiculous.</p>
<p>DMOC: you had to use completing the square which i vaguely remembered, but it came out to (-2, 5) for me</p>
<p>Okay … 1 skipped, 0 wrong (?).</p>
<p>was the one about r=cos0, (.5,pi/3)?
that 0 is supposed to be a theta</p>
<p>yes powerbomb</p>
<p>overall I thought it was really really easy, which is nice. 800 here I come.</p>
<p>yeah, that’s what i got.</p>
<p>another answer</p>
<p>the angles alpha and theta can’t add to 150.</p>
<p>Hey did everyone have a section in their test (questions 25ish to questions 30ish) where they had several “A”'s in a row and then several “E”'s in a row? I thought that was a little interesting. :)</p>
<p>wat was the answer for the piecewise function. i think #48
the ? asked: what is the value if f(4.7)?</p>
<p>Here are my answers starting from the back, skipping some:</p>
<p>+99%tile
none exist
.7
150 (theta + a cant exist)
(-2,5) ellpise
tan(x) is odd.
-4.85
3.14
.5, Pi/3 (polar)
8.49
xyz plane with x-3 is a plane
sec67
167.6
RT
K<=o for x intercept
x(m-60t)</p>
<p>Why was one of your answers r*t? I thought it was just r becuase f(x) = rx + s so x is just the value that’s being put in and r is the slope.</p>
<p>Also … graphs do “intersect” even if they touch each other only at one point … like tangents, right?</p>
<p>yep it was rt.
just plug in for f(x) and g(x) like f(x)=2x+5 and g(x) = 3x-3 and do the composite and u get 6 which is rt</p>
<p>DMOC: it is (-2,5) because when you did the completing the square, it ended up being (2x-4)^2, meaning the x-coordinate of the center was at -2. (And there was only one option with that being the x-coordinate)</p>
<p>headsniped: I put 3.7, but I was not sure. I think the function was </p>
<p>f(x)= { x, 0<=x<1
{ f(x-1), x>=1</p>
<p>headsniped it was .7. or i may be wrong lmao.</p>
<p>what was the 3.14 question. I don’t remember that.</p>
