<p>kevinscool, for the one you said "y>2, and xy=y+x"... whatever that question was... all you had to do is just plug in really big numbers and really small ones into the equation. i did that and saw the answers were either approaching 1 or 2... canceling out the answer 0<x<2</p>
<p>im 99% sure i guessed 1<x<2. Sweet lol</p>
<p>what was the number of that equation? the one with 1 < x < 2</p>
<p>anyone remmber the gridin question with the cynlinder and cone with the liquid? (gave u formula for vol.)</p>
<p>The grid in with cone and cylinder was 2</p>
<p>cone/cylinder was 2</p>
<p>i got 2 too</p>
<p>math is easy this time, but there was one ques i wasn't sure about</p>
<p>how did you get that, and do you remmember the question?</p>
<p>For the cylinder and cone question, i found the volume of both. for the cone it was 18pi and the cylinder was 54pi. then i made a ratio:</p>
<p>(18pi/54pi) = (x/6)</p>
<p>x= 2 inches</p>
<p>simple as that!</p>
<p>y>2, xy=y+x
I wrote a simple proof on this trivial problem.
First of all, it cannot be less than 1
y>2 means they're not including 2. If you put 2 as y
it gives the answer as 1. So it cannot be equal to or less than 1.</p>
<p>1.5<em>3=4.5
1.5+3=4.5
x</em>3<x+3, where x<1</p>
<p>So, I picked 1<x<2</p>
<p>I got the abc question wrong, because I forgot that a, b, and c had to be (positive) integers. My answer worked, but it wasn't an integer.</p>
<p>Yeah, I got the same thing, whatiscollegeok. It's (1/2)hb, and both of those were x, so it was (1/2)(x^2)+3y, the area of the rectangle.</p>
<p>its (x-3)^2... this was already discussed and agreed upon.</p>
<p>its x-3, not x. the reason is because there was a drawing where x was an entire side, yet the triangle's height did not represent that entire distance. x-3 was correct, because on the other side it labeled the difference as 3.</p>
<p>i am 100% sure.</p>
<p>Where? <.<</p>
<p>Wats the 256 for? is that in the grid in. Wat was the exact question... doe anybody remember</p>
<p>Does anyone remember what the exact question or information was for the last grid-in problem (Ans: 13.5)?
That's the only problem I think I may have missed... so I really need to know because I don't remember what I put.</p>
<p>the graph and the x and y intercept. then theres a rectangle. u graph it on ur calc, find y, find x, multiply to find the areaof the rec</p>
<p>what was that question where u had some complicated graph, and u were suppose to represent the angle of x with y? or was that experimental?</p>
<p>the one about the plane and circle with 6pi, shouldnt it be more than 4 or infinite since u can rotate the circle any way inside the plane u want?</p>
<p>and the one about rotating with roman numerals was it I and II or I II and III?</p>
