<p>Was the volume question V(t) = 3t + 50 on Level 1 or on Level 2 (I can't remember)?</p>
<p>thats true, but it said set of ALL points. the 4 points would be included in the circles, 2 in each circle.</p>
<p>Yeah, exactly. Set of ALL points. The circle would have the set of all points. There's more than 4 points that applied.</p>
<p>argh thats 42 raw then....hopefully no more wrong and i get a 790</p>
<p>just a question.. about the heartbeat one... do you guys really think that a question that far into the test (almost at the end) would be just about plugging and chugging? or was i thinking about it too much?</p>
<p>I have -6 for the 6 I skipped. I'm wondering what questions I MISSED though. Hopefully no more than 2... or else 800 is not possible.</p>
<p>Yeah, it was ~#44, which is why I question how plugging in 60 to get 120 would be correct. It was nearly the end, and it did not seem possible that you could get an answer that quickly?</p>
<p>Can anyone else comment on the perp. line question? Was it circles or 4 points?</p>
<p>ahh, I see. For some reason, I thought they meant that you would include not just the points on the circle but inside the circle. Oh well, I was in a hurry.</p>
<p>I feel kinda dumb! lol</p>
<p>how many did everyone skip? I thought they were all do-able and I only skipped 1...</p>
<p>I skipped the plane one with the lines...because I didn't study that and just got lost in the wording =P</p>
<p>Edit:
For probability, I got: 5! - 10!/5!</p>
<p>And for the function one, it was f(1) < g(1) through process of elimination =P</p>
<p>Petri dish was 322....pretty sure.</p>
<p>The 1/f(x) one was reflected across the y=x line right?</p>
<p>skipped: last probability question, plane/line question, and the functions f and g...f-g for x=1 is below the x-axis</p>
<p>not sure about: pet dish (ALKSJDLAKDSJ I PUT 396 i was in such a dilemma choosing between C or D..), heartbeat, and one that showed a graph and asked what the graph of y= 1/ f(x) looked like.</p>
<p>Oh yeah. That was the question. What was 1/f(x) supposed to be? Was it A or C??</p>
<p>the inverse of an f(x) graph is its reflection over x=y</p>
<p>How does plugging in work for the Sin(2pie t) question. That would give you Sin (120 pie) which is 0 and that can't be the answer.</p>
<p>aquamarinee-it was A</p>
<p>That was C then right? I think I put C... Was it the one where it crossed y=an integer number I cannot remember?</p>
<p>for the sin (or was it cos?) qtion about the periods, i remember the original as being sin(2x+4) or something, so the pd is 2pi/2, but i specifically remember seing a choice that was sin(x+2), which did not have the same pds as the others... am i just making this up?</p>
<p>1 / f(x) was 'A'</p>
<p>sky 2345: I think the equation was 120 + sin(2pit)</p>
<p>Therefore it would become 120 + 0 = 120</p>
<p>Circles or 4 points. I still don't know that one either... I'm slightly confused right now... I'm pretty sure it's circles??</p>
<p>Was the 1/f(x) graph the one where the graph crossed the y-axis at some integer number, since the original crossed at y=1?</p>
<p>i skipped 4
and missed 3 .. so far: the hb one, the salary one(...), and the pet dish area </p>
<p>this is depressing</p>
