Official June Math IIC Discussion!

<p>Yes. It was 30%</p>

<p>jeans was 30</p>

<p>for the triangle perim. weren't the sides of the cube 7 and not 3?? so the triangles were the diagonals of the cube. 7(root 2) * 3 = 29.69? Im pretty sure that was the answer, confirm??</p>

<p>Was it just me, or were the last like 7 questions rediculously hard? I looked at the last 2, and left them blank, I think i got the probability of the fire alarms working wrong.</p>

<p>I know i left a total of 6 blank, and i think i got some wrong.</p>

<p>Also, early in the test it had a triangle with 2 sides being radii and an altitute which bisected an angle into 2 congruent angles. I didnt know what the side was in comparison to Thetas.</p>

<p>Let us start!</p>

<p>The fire alarm question I think was the highest answer because it was the only one where the probablity was greater than the probabily of either fiire alarm alone.</p>

<p>2100 i think i put 2sin(theta) for that one</p>

<p>lets make a list of all the questions and answers. This will help us see if we should cancel our scores or leave them. If you don't remember, look at your calculator and press 2nd entry(for TI-83/84) and look through all the problems you put in your calc.</p>

<p>WHAT WAS #1?</p>

<p>i put sin2theta, but i just completey guessed</p>

<p>Let's compile our answers, for me (I had form 5C2):</p>

<p>x great or equal 3
39.55 for the bouncing one
2sin(theta) for the length of chord AB
3*7root(2) or 29.67 for the perimeter of the triangle on the cube
x = y or t = 0
-x^2 + 2
4.8 for the height of the smaller cone
30% profit for the selling
sec^2(x)
for g(x) = f(x -1), I chose the graph that shifts f(x) one unit to the right
lines AB, BC, AC are all needed in the law of cosine to find angle ABC
(-2, 4, 0) for the double distance but opposite direction</p>

<p>?? two different polynomials, each has two distinct real-zero solutions one; at least for one value x that f(x) and g(x) have in common; how many distinct real-zero solutions do f(x) * g(x) --> I put 3 or 4 ??? no idea on this one</p>

<p>please confirm or make correction</p>

<p>"I think i got the probability of the fire alarms working wrong."</p>

<p>You had to find the probability of neither alarm working (1 - prb alarm one working x 1 - prob alarm two working), and then subtract that from one.</p>

<p>As I recall, the answer was 0.997</p>

<p>"Also, early in the test it had a triangle with 2 sides being radii and an altitute which bisected an angle into 2 congruent angles. I didnt know what the side was in comparison to Thetas."</p>

<p>A: 2 sin (x)</p>

<p>Unfortunately, I went back to do that problem right at the end of the test. I figured it out, and the proctor was just about to call time as I was just about to fill in the bubble. I quickly rushed to fill it in, and accidently bubbled in B!</p>

<p>Everything above is confirmed.</p>

<p>Can someone please tell me how you got 4.8? I don't remember if that's what I got.</p>

<p>im pretty sure the answer to #1 was 2.</p>

<p>how many can you miss and still get 800?</p>

<p>Are we sure about the cube tragnle question?</p>

<p>i put 2sin(theta) as well, and i got 30% for the jeans</p>

<p>what was the cone ques? with the 75 volume instead of 80?</p>

<p>that stinks, i think it was 4 for the factor one</p>

<p>i think it was 2 or 4 only pudding??</p>

<p>the bouncing one was much smaller than 39. it was under 10 but i cant remember exactly what</p>

<p>For sec^2(x), I think I put a^2 + 1 because of the identity,
tan^2 + 1 = sec^2</p>
