<p>I believe the slope was 3/4…it could not have been negative as the tangent line proceeded horizontally and vertically up simultaneously. The center was 3,-4. Rise/run was -4/3. the line through the center is perpendicular to the tangent line as it contains the radius. Take the opposite reciprocal…+3/4.</p>
<p>i got 3/4 because its the opposite reciporacal of -4/3</p>
<p>Spkrap: The Langston question was along the lines of: Some year saw the publication of Langston’s story, blah blah blah, which had lain on his desk for blah years. Since there is no direct object, it might be no error. Someone should try to use the reference I found to figure it out because I myself cannot come to a clear conclusion (I’m leaning towards E).</p>
<p>i got 4… but im not really sure- anyone else?</p>
<p>lain is used to recline. wasnt the sentence referring to music? so the music couldnt have been lain down. ?</p>
<p>3/4 for slope of tangent line.
(you know you’re in calculus when you read “slope of tangent line” and you think derivates -.-)</p>
<p>the question was:
y = h / sqr(x)
x = kz</p>
<p>when x is 4, y is 9, and and z is 8
it worked out so that k = (1/2) and h = 18
then it asked what is z when y is 2?</p>
<p>for y to be 2, the square root of x has to be 9, so x has to be 81. Since x is equal to half of z, z must be 162</p>
<p>Dentrix the slope was 3/4</p>
<p>What was the question that you guys got 4 as an answer? (Not the % problem, but on the grid-in one)</p>
<p>KenDoll I had that question too. Was that section experimental? I really hope not because that section was pretty easy. Also, the other question with the three bullets dealing with direct and indirect proportionality did you have that section?</p>
<p>Haha calculus for the win, and spkrap I believe it was about Langston’s story that was published but had previously lain on his desk for a number of years prior to publication. I am caught in between lain and laid because lain does not need an object, which probably applies to this situation, but at the same time refers to reclining which is probably not applicable. Oh well</p>
<p>firered I had 4 math sections and still did not have a bullet question dealing with proportionality. That section is certainly experimental if you are in the right thread (right test with dolphin and human behavior, physics, sensei cartography, etc.)</p>
<p>i got x to be 15</p>
<p>because y was 30, I extended it to be a triangle that would be equilateral because the two lines were parallel. that meant the reaming angles had to be half of (180-30) = 75. if you dropped a line perpendicular to that, it would be 90-75 = 15.</p>
<p>sorry the explanation isnt very good. I kinda nned a picture to explain it</p>
<p>@kendoll222- we were talking about different problems, sorry. yeah i got E for that one i think.
do you remember the one that was like “x is proportional to y. y is inversely proportional to z.”</p>
<p>YES i had all those passages! I am so happy right now, because I left two completely blank in that section.</p>
<p>Alright lets talk CR now-</p>
<p>For Dolphin one, did you say:</p>
<p>Humor for a defense
or
Flippancy for an undesirable situation</p>
<p>How did the author of that physics passage view that stupid theory (not inertia) that Physics students still believed in? Wrong but plausible?</p>
<p>And TV, Teachers, and parents all “impart knowledge”?</p>
<p>Skorpius, I chose “Flippacy” because he seemed to be more accusatory of people who acted that way, and his defense did not come until later. I was very unsure though.</p>
<p>yes and yes…did you get “surprised”?</p>
<p>I do not believe that was experimental- multiple friends of mine had that!
and i do not recall a problem about bullets and proportionality- sorry!</p>
<p>i got ironic and something. I was debating between that and flippancy for the answer to the tone about how one would react to woof! but thought it was ironic because you are talking to a person but treating them like an animal… not sure though.</p>
<p>so you’re saying that section was not experimental?</p>
