<p>I just multiplied the thing’s height by it’s base (pir^2). And I don’t think it was a cone because it’s surface was curved.</p>
<p>Also yeah, what was the answer to that 1/g(x) question? I put the horizontal asymptote answer.</p>
<p>So what did you get for the answer for the cone one?</p>
<p>yeah and the yahoo answers also said something about a cylinder. truncated cone? haha but probably shouldn’t rely on yahoo answers.</p>
<p>what about the AB:BC one? C looked good to me but it seemed too easy.</p>
<p>Overrated, the question you linked to is a triangle rotated around x = 2. The difference is that it doesn’t touch the line, so there would be a cylinder removed from the middle.</p>
<p>Isn’t the embargo still on?</p>
<p>The cone was like 8.8 or something like that. I integrated and got it in 5 secs.</p>
<p>I put x = 3 for the 1/g(x) one.
It was g(x) x f(x) = 1, which is also g(x) = 1/f(x), then for f(x) = 0, there would have to be an asymptote, so I picked the x on the original f(x) graph that had an asymptote (3).</p>
<p>Is that right?</p>
<p>The line was rotated about the x axis not x=2</p>
<p>oo true. </p>
<p>what’s an embargo?</p>
<p>can someone explain how the curve works? i dont really get it. </p>
<p>i dont remember getting 8.8 for the cone. shuckss</p>
<p>Protagonizer: x = 3</p>
<p>The 2/5 and 3/5 lines, I got 9. something for the angle?</p>
<p>Thought it was pretty easy… it was definitely 987 for the satellite one and what was the 2/5 and 3/5 lines question again cause i don’t remember having too much trouble with it</p>
<p>i got x=2, 3 was definitely too obvious. and i got 9. something for the angle too choice a</p>
<p>It was just asking for the angle between them. Something like tan(3/5) - tan(2/5).</p>
<p>What was the answer of the absolute value question??</p>
<p>absolute value question u could figure out by just plugging in values for a and b, i dont remember what the answer was</p>
<p>The answer was b, which I think was answer choice D.</p>
<p>…
it was obvious because it was right?
it was the x at which the asymptote occurs and the value for g(x) = 1 / f(x) when f(x) = 0 (since the 1/0 expression is impossible or whatever math term you use to describe it)</p>
<p>That was so incredibly easy compared to the Sparknotes #1 Practice Exam. I think I got an 800.</p>
<p>Hehe, I spent about 5 minutes trying to do the (0, 2), (pi, 1) problem because I was solving for distance rather than slope. Can we get a consolidated answers list going?</p>
<p>k lets start doing the list</p>
<p>for the 2/5 3/5 question the answer was defiantly 9.something because i had a program in my calc that can find the angle between two slopes. and for the rotate around the x-axis question i could not figure question out what it was asking me to do, but i got 18.something for that</p>

<p>It wasn’t 987 for the satellite one. You make a triangle and convert feet to miles and add it to 255. Then you use tan of the angle they give you and you find the answer. My friend explained that if you used sin, you would get the answer you got. Therefore, the answer was D and 1000 something.</p>
<p>haha well i competely failed it >.< does leaving 5 blank still give me a chance at 800? what answer did you guys get for the one about 0<y<4, what happens if y = 5 or somethin</p>
