November 2010 MATH 2 Discussion Thread

<p>^ yep agreed michael209.</p>

<p>Michael209 that is what i was referring to i didnt remember the entire answer, is that what you put?</p>

<p>ihatetesttaking- I think that is what I circled. None of the other choices I tried worked on plugging in.</p>

<p>for the parametric question, was it (E) x=-t^2-1 and y=t? (i think)</p>

<p>What about the question in which an unknown function was given and points (-2,2),(1,4) and another one satisfied it. We were supposed to comment on the number of zeroes or something? What answer did that have?</p>

<p>yeah that’s what i put, ihatetestaking
pretty sure it’s right. calculators never lie :D</p>

<p>What was the answer to the first problem!</p>

<p>austrianpog- Do you remember the other choices? I don’t remember which one I circled for that.</p>

<p>perfect pixie- i think the points were (-2,-2) and (-1,4)
so there’s one zero in between -2 an -1</p>

<p>The probability question (I think it was the second or third last), it’s answer is 2/9?</p>

<p>Michael- Yay! That’s what I circled. Wait, no other zero right, I mean b/q the other point and one of these? Only one zero in the entire eqn?</p>

<p>austrianpog thats what i put</p>

<p>protoslg what was the first problem?</p>

<p>does anybody remember what the one with 4 points that made a square and then they doubled the x,y values, what would be the new area? i dont remember what i put</p>

<p>austrianpog, Yeah that was the answer.</p>

<p>Perfect- I got 2/9! </p>

<p>Proto- What was the first question…? haha</p>

<p>pianoman- i put 4 for the square one</p>

<p>for the question about the vertices of the square being doubled and the resulting area…was the answer 4?</p>

<p>Yea 4 times bigger for the area.</p>

<p>yea thats sounds right</p>

<p>and i put 2/9 also</p>

<p>last problem = abs(secx)?</p>

<p>Pianoman- For the area of the squares question, the answer was 4. The larger square’s area is 4 times the area of the original.</p>

<p>Michael- Yep. abs(sec x).</p>
