<p>Overall, this was an easier test than expected, but there were some tricky questions that fooled a lot of people. Expect a similar curve.</p>
<p>thank you :)</p>
<p>How accurate is sparknotes Math 2 scale?</p>
<p>i think it is infinite because it asked specifically for “non-congruent triangles”.</p>
<p>It would be 0 if it asked for “congruent triangle”, which it didn’t.</p>
<p>isnt the one about the parabola intersecting the x. k<0 ,because if k is 0, it doenst intersect, the graph doesnt go beneath the x axis… it goes above it. intersect the x axis means go through the line y=0, but y=x^2 doesnt go through, it just touches. so i think it was k<0… and i think it was 3.7 for the piecewise, because for the first part, if x is between the -1<=x<=1 ,then… thats your y-value, just x. but if x is >1 then tis watever the x-value -1</p>
<p>widly05: sparknotes uses the same scale found in the blue collegeboard book.
So it is pretty accurate</p>
<p>what was the one on which function is odd. it was like either cos x, tan x, log x, etc.
i put log x, but im starting to think i got it wrong.</p>
<p>^ Wuchu: i believe it was tanx</p>
<p>okay so far: 1 wrong 5 skipped…</p>
<p>i remember 3.14 question. The tangent was 3 and the radius was 1. Angle was 30. They wanted the hypotenuse of the traniagle with a segment of that tangent and the diameter. So that segments was 3-tan 30. Then using pythagoras I got 3.14</p>
<p>ilovecars- if k = o, then the graph is y=x^2 which touches the x axis.</p>
<p>For 49, the answer is no triangles. Use the law of sines, and when you solve the ratio, it says the sinx = 1.xxxxx which is greater than the range for sin, hence u get an undefined in ur calculator.</p>
<p>y=x^2 does intersect the x axis… at 0,0.</p>
<p>does anyone remember that cone problem where the diameter was 8? was the height 10 or was it the lateral height?</p>
<p>nope ilovecars on both. it was .7 and k could equal 0 because it still intersects the y axis (even though it only touches it)</p>
<p>The triangle one was ZERO not infinate. Because no such triangle (with given sides and the angle) can exist. Law of sines says so. </p>
<p>I dare you to construct a triangle with the given conditions. Good luck, because it isn’t possible :)</p>
<p>if it intersects the x axis… then there MUST be a y-value <0 … otherwise its not intersecting…</p>
<p>that just isn’t true Ilove cars.</p>
<p>10 was the lateral height.</p>
<p>sqrt(84) was the height.</p>
<p>x(m-60t)
was that the answer for the D=RT problem?</p>
<p>i thought it was x(m-t/60)??</p>
<p>AND THIS IS REALLY EMBARRASING LOL</p>
<p>but what was the answer to the domain problem? like number 5 haha?</p>
<p>the bottom was x^2+1</p>
<p>what score will skipped 6, 7 wrong get u?</p>
<p>I dont agree with cars, cuz i mean even if its y=x^2 and anyone asks for the point of intersection with the x axis you would say 0,0. U wouldnt say it doesnt intersect the x axis</p>
<p>ok and there were only 50 problems, right? I forgot to check lol.</p>
<p>if its t per minute, then 60t per hour.
the domain problem was all reals because x^2+1 is never 0.</p>
<p>No because if x is zero, k has to be 0. therefore, for all values it’ll have to be <= 0</p>
<p>for the k problem that is.</p>
<p>domain was all real numbers btw, and the other answer was m (because 1 machine produced m in an hour) - 60 t (second one produced t in a minute). This gave the diff per hour. then multiply by x</p>
<p>actually… yeah it is <=0… iono i guess i thought it corsses the x-axis. can someone explain the .7 thing cuz i htought it was 3.7…</p>
