<p>thank you everybody thats what i put to make sure was that choice A?</p>
<p>kin3sis: i thot it was A too
but i chickened out and i left it blank xD</p>
<p>I put 2 and 3 only but not sure though either for the flags (logic) problem.</p>
<p>The periodic function question's answer was 3 you guys since the sinusoidal function returns to the same point(0,3) every 20 x-coordinates and thus f(100)=3.</p>
<p>Does anyone remember what the side of the cube was in the problem which contained a triangle in the middle of the cube. For that problem, I remembered using the Phytagorean Theorem to figure out one side of the triangle and then multiplying by 3 to figure out the perimeter of the entire triangle.</p>
<p>ALso, does anyone remember what the answer was to the question that asked about the height of one of the triangles of the triangular pyramid???</p>
<p>Man, that was a long test. Also, I disagree with you guys regarding the probability question since I got 0.06 as the answer. I'm 100 PERCENT sure they asked you what the probability was that you would get the two die to add up to 5.</p>
<p>Man, that was a long test.;)</p>
<p>^no it was greater than 5. im 100% sure it said greater than 5 because i spent a ton of time staring at it because i wasnt sure to use permutations or w/e
as for that problem, i doubt its 3
as for the cube,
its not the same length all the sides. one is 10 while the other two is each root(50)
as for the pyramid, it was base of 4 so from midpoint to center point of square is 2, height is 8, use pythagorean theorem (8.25)
for flag i put 2 only as well (B)
but then i wasnt sure if it was 2 only, or none?
-_-</p>
<p>just to sure as well the graph f(x) compared with f(x-2)+1 is shifted to the right and one unit up which is E right?</p>
<p>It was definitely II ONLY for the flag problem!!!</p>
<p>^yeah, the one on the right...there were 2 but lol thats all i rememebr; its shifted over 2 to the right and one up</p>
<p>it was a long test. i had a killer headache, and the room i was in; the heating system made this banging noise the WHOLE FREAKING TIME.</p>
<p>evil asian dictator ! No the question was that sum EXCEEDS 5?</p>
<p>I still think f(100)=1.
Yes, the probability was asking the SUM of the two numbers GREATER than 5. There are only 10 choices out of 100 to get LESS than 5. So the answer is 0.9.
I can't believe I got f(x-2)+1 wrong. Careless mistake :(</p>
<p>I got B for the absolute value problem, please say that's right lol!!!!</p>
<p>OH YEA, how did you guys do that one problem which stated that the square of the difference of a number and its reciprocal equals 7 and asked you thge find the number.
(x-1/x)^2=7 right??? Then how come none of the answers matched up grrrr!!!!:confused:</p>
<p>I'm pretty sure that 3 is right for the periodic function problem since periodic funtions repeat themselves, in a period of 20 in thsi case. All my friends got the same answer...oO well.</p>
<p>evil<em>asian</em>dictator</p>
<p>haha i got B for the abs. value problem as well.. but i'm still not sure if it's right. at least someone got the same answer as me lol. </p>
<p>for the difference of number/reciprocal blah blah thing.. i just plugged in the answer choices hahah. i forget what the answer was though sorry. one of the choices definitely matched up though</p>
<p>i still think the periodic function one was 1.. =/</p>
<p>The answer for that problem (x-1/x)^2=7 is when x=2.98. I used the calculator to plot 2 graphs and find pt of intersection, much faster!</p>
<p>it wasnt a period of 20...it started at 3 and period was 7. i think u misunderstood =|
that reciprocal problem was weird. i just plugged them in. its 3; i forget which letter that is</p>
<p>hey i remmebr that prime number problem
it was only x+y-1
or something (I only)
right?</p>
<p>I am 100% sure it is 1</p>
<p>That number and its reciprocal was D. (2.98 I think)</p>
<p>What were the choices for f(100).
1,3, (1/2), ?, ?</p>
<p>hey people the question for the maximum value of sinx cosx was 0.5 a choice? If yes, DARN!!! I was looking only at the value and didnt see a choice?</p>
<p>yeah it was .500 (C)?
LOL =x
yuck
i still have the equation for the ferris wheel in my calculator</p>
<p>flyaway, yah i think i got the same as you for hte prime number problem.. i think they used r and s though. but yeah i got I only =)</p>
