<p>@lolilaughed, oh yeah. The question was like a+b= 10 ab = 20 or something
What is the sum of the recipricals of a and b</p>
<p>I got 1/2</p>
<p>"@ hipster-I got n greater than or equal to 9! somebody said the answer was n greater than or equal to 6! but I don't remember that as an answer choice."</p>
<p>I got greater or equal to 9!. I don't think greater than or equal to 6! was an answer. It was like..</p>
<p>A. Blah
B. greater or equal to 3!
C. greater or equal to 9!
D. Blah.
E.Blah</p>
<p>Anyone get the y-intercept of f(x+2)? I think I got (0,2) because don't you move the graph two units to the RIGHT? not UP?</p>
<p>The correct answer on the cone one is 1500.</p>
<p>Radius was 15 and height was 20.</p>
<p>If you mixed them up, you got 2000, if you forgot to divide by 3, you got 4500, if you botched both, you got 6000.</p>
<p>Yea, I meant the sum of x+y = 10 but the reciprocal was .5 * sorry.</p>
<p>Hmm, if 25 was the slant then what I posted should be correct.</p>
<p>hey Pynne dont worry man/woman?, the answer was 1500pi</p>
<p>wt was the f(4) problem?
can anyone state the problem?</p>
<p>@wis3ly, the answers were</p>
<p>A. x > or equal to 3!
B. x > or equal to 6!
C. x > or equal to 9!
D. Divisible by 9
E. Divisible by something</p>
<p>Looks like the cone question won't be solved until the scores come out. Oh wells! Wis3ly, there was a choice for n>=6. And also, it was (0,5), wis3ly. You move it 2 to the left if it is f(x+2)</p>
<p>Edit: We have A LOT of answrs to questions floating around. Compilation?</p>
<p>whoooa, the posts are all over the place! :<</p>
<p>I thought the triangle rotating one was about the XY side, in which case, it should be 1500pi.</p>
<p>hahaa bigweight, thanks! xD</p>
<p>Go back like 2 pages. We talked about it there; They gave you two points. find f(4) or something.</p>
<p>nope WANTIVY, the answer to f(x+2) was (0,4), i drew it with my pencil. LOL</p>
<p>Who got 1:8 as a ratio for the spheres?</p>
<p>^ Oh yes, for the curve that shifted left. The answer was definitely (0,4); I drew it with my pencil too.</p>
<p>Yes, I got 1:8 too r to 2r under cubed is r^3 & 8r^3 : 1/8</p>
<p>Moi aussi. :}</p>
<p>what about the one where it asked for the x value of the maximum from [-2,4]...almost put the max i found on my calc until i saw the value at -2 :)</p>
<p>There was also a problem about the inverse of f(x) being equal to g(x). Does anybody remember that problem?</p>
<p>I got teh answer as -2 btw because endpoints are critical #s as well.</p>
<p>also, what about the one one where f(f(x))=x...which x makes it true?</p>
<p>Answers I remember at the top of my head</p>
<p>1:8 ratio
1500
Period: 2pi?
(0,4) for F(x+2)
(2,2) for equilateral triangle
2x+ 4 or something like that for -1000 function question
Also for the (-2,4) it was 2.41 or something</p>
<p>Wasn't the answer for the maximum at x=2.39?</p>
