<p>I was probably in a rush and read it as sum instead of product. x_x There wasn't enough time for me to even go back and attempt the 10 problems I skipped.</p>

<p>lol, yea i learned that if u skip it, u pretty much omit it lol</p>

<p>Guys for the dog one here's what I remember.</p>

<p>for I it asked you if the simple equation f=42x (dunno if its 42) was equal to xx. This was true.</p>

<p>II was not true; i'm pretty sure about this.</p>

<p>III i dunno if it was true. The question asked g(x) starts (???) to give a smaller value at 6 years. I remember getting a result at f(6)=47-49 (i don't remember exact values) and g(6)=42-44. But when i put f(5) i got=40-44 and g(5) i got 38-39. I figured out that that g(x) gives smaller values starting at 5 years not at 6 years. So in the end i don't know whats right or wrong :(</p>

<p>Anybody still have the functions on their calculator?????</p>

<p>For what question number was this the answer "time between max height and when the ball hits the ground 1 sec"? I don't remember it so i hope its number 49 or 50 which i omitted.</p>

<p>Also I had (-1,-5pi/4) for the point not in the same quadrant as (1, pi/2). I'll ask my math teacher tomorrow if I'm right and I'll post the answer.</p>

<p>i personally put the same answer for the polar coordinate one, atomicbomb, but wouldn't (1, 13pi/4) not work either? that was the consensus earlier.</p>

</ol>

<p>yea 1, 13pi/4 shouldn't work either lol, idk weird</p>

<p>I still can't believe I circled the wrong choice for the sinx.cosx one. Arrghhh !!!</p>

<p>lol wht did u say?</p>

<p>wasn't the dog question on I and II? I think II stated something like after F(4) the second equation starts to increase more...something about a 28. idk but i remember that being right.</p>

<p>idk i completely forgot dog one</p>

<p>there were definitely two that worked..choice I and the other choice with g(x) starts to increase faster than f(x) after 6, i just dont remember if that one is choice II or III. GRRRR my memory.</p>

15 What value of K is needed for the equation to work? the equation had an absolute value thing [x-3]=K if [3x-9]=1. K=1/3?</li>
</ol>

<p>ok so we got 15/50 lets get two more problems each and then when i check back (1-2 hours) we'll have over 25 problems done!</p>

<p>minimum number of gloves to pull out in order to guarantee a match pair: 4</p>

<p>F(100) for a graph: 1</p>

<p>s+1 r+1 roots: x^2+9x+10</p>

<p>Range of y=cos (x)..</p>

<p>A question about from 1940-1970, x amount of money triples...so what is the annual rate of increase from 1970-2000..</p>

<p>Probability of picking two even numbers from a set {1,2,3,4,5,6,7,8,9}</p>

<p>And I think there was a half-life question? About something being reduced to 25%.. Or maybe I'm mixing up chem and math..hahaha</p>

<p>i think the probability is 1/6?</p>

<p>I put (4/9)^2. I suck at probability though.</p>

<p>oh i did it by (4/9)(3/8) = 1/6</p>
