<p>that seemed relatively easy </p>
<p>skipped 3 and i can only think of 1 i got wrong (spheres intersection)</p>
<p>hoping for 800</p>
<p>what was the speheres intersection one? it never said they were not solid. what about the one with the 3 points and its largest angle?</p>
<p>spheres ARE solid tho....
ugh iono nemore
someone explain y its point and circle</p>
<p>If the spheres were solid, the intersection would be either a sphere or a point, which wasn't an answer. If they're hollow (which you have to now assume) then it's a circle and a point.</p>
<p>largest angle: tan^-1(3/2)*2; don't feel like getting a calculator</p>
<p>was largest angle in triangle (0,0), (-3,2),(3,2)</p>
<p>it said in the question to look at the intersection of the spherical surfaces</p>
<p>ergo...circle and point</p>
<p>well...for the circle...u just hvta kinda imagine it...for the point....say u take the two circles and defined each by like all its points....thus, when u take the intersection of the two sets (upside down u thing), then you hv one more of intersection</p>
<p>umm there's this one problem toward the end...something about f(0)=f(6) and there were 5 graphs...what was the answer?</p>
<p>the one that looked liek x^2 or something
the x's had to be the same</p>
<p>I thought the spheres were solid, as well.</p>
<p>f(0) = f(6) is just where x=0 and x=6 have the same y value</p>
<p>The question asks for intersection.</p>
<p>Think of the double cones and how they come up with conic sections.</p>
<p>^^ it was like C/D (dont remember) the graph that was a polynomial that was like yeah........</p>
<p>50-3<em>1-3</em>1.25 = 43
3Pac, You are on the border line for an 800!!! :)</p>
<p>hey shadow rider how about 5 omit and 3 wrong?</p>
<p>can someone explain me the "which does NOT change?" question?</p>
<p>(a median / b mean / c range / d stand deriv / e don't know)</p>
<p>5 blanks, 3 unsure.....score??</p>
<p>i'd say a 780 or more.</p>
<p>c. range. I'm positive.</p>
<p>really ....... for me? hopefully nothing more wrong! but at least 700 + rite guys?</p>
<p>In what area was the range 99-100 problem ... I DID NOT SEE that problem... did I do something wrong </p>
<p>so far </p>
<p>5 blank
-3 </p>
<p>looks like 730 -- 770 for me</p>
<p>wasn't r just 8... because it turned out to be 8+6i=r+si</p>
