<p>Hell yes, yes I did sither...</p>
<p>15 and 22 are correct...though i may have put 21 forgetting the 0 haha</p>

Was that the one that was like (x+2)^=9? If so, then I'm pretty sure I put 8 too.

</p>
<p>Yeah:</p>
<p>(x+2)^2 = 9
(x+2)(x+2) = 9
x^2+4x+4 = 9
x^2+4x+3 = 8
(x+3)(x+1) = 8</p>
<p>Excellent.</p>
<p>where is that guy who has a bunch of the math answers?</p>
<p>hhmm.</p>
<p>let me think of another one.... ok... what is that one that was perpindicular to 3x+2... is it (-1/3)+2?</p>
<p>the 3 digit with 3 conditions was 20 right?</p>
<p>I got y = -(1/3)x + 2 for the perpendicular problem as well.</p>
<p>i remembered a part of a few...</p>
<p>there was one where there were 3 jars.... one red in each jar... probability of all read would then be 1/27</p>
<p>there was one which i cant remember that well it was right before a grid-in... it was something like (ab)^2b=a^b times something else..maybe..I solved that by putting in a number.</p>
<p>Another one, which I didn't have enough time to solve, was a temperature problem where it started a 6 AM at 13 degrees, went at a constant rate to 3 pm and then decreased to 9 PM to 17 degrees</p>
<br>
<blockquote> <p>"what was the answer to the question where there was 1,2.8..11,13 and it said k is greater than 2/3 and what are the possible values of k?"</p> </blockquote>
<br>
<p>didnt it say that 2/3 of the numbers are greater than k..and was a grid in so u put either 1 or 2.8 ?<<</p>
<p>Err yeah, I assumed k was one of the six numbers, so I put 2.8...</p>
<p>does any 1 remember a problem that said something like 4/(x-1) and it asks for what value of x makes that expression an iteger and answers were a bunch of fractions.
NOTE: i dont remember what number was in the numerator, so i just put 4</p>
<p>i have a very important question!!! i am begging SOMEONE to answer it for me... so far no one has discussed the problem involving a circle with two tangential lines. it asked about the length of an arc on the circle. does anyone know if this section was experimental? usually i am good at math, but i really didn't know how to do that... help!!!</p>
<p>i remember only whole numbers as answe choices.. i think it was soemthing like 5, 6, 8, 10... something like that... there was a circle with two tangents which intersected each other to the left of the circle. the circle was set at the origin of a coordinate plane. the problem gave the angle (x) of the intersection point (x=40). it then asked for the length of a small arc on a part of the circle. i still cant figure it out.</p>
<p>For the integer problem, I thought it was 4/(2x - 1), in which case I put 3/4 as the x-value to give an integer for the function.</p>
<p>no its not experimental... and here is my explanation:</p>
<p>draw a triangle from the midpoint of the top circle to the 2 other circles so it forms a triangle
or... 2 right triangles
take a right triangle
you know the hypotenuse....8 because its the 2 radii
you know a leg.... 4 because its the 1 radius
\and then do pythagor
\so its square root of 48 for that side
so in the end its square root of 48 plus 8
or....4rad3 +8</p>
<p>ildjing whose problem are you answering?</p>
<p>the 3 circles</p>
<p>Does anyone remember the exact phrasing of the prime number question? (p is a prime number > 5, etc.)</p>

<p>I HAD THESE!! The red jar, I put 1/27 as well. There were three jars, each had 3 balls, where only 1 was red in each jar. It asked, what is the probability that a 3 red balls are to be drawn?</p>
<p>The 2nd one you're talking about is (ab)^(2x) = a^x*b^y something like that. And it said solve for y, or something. I just plugged in numbers, I forget what I got though.</p>
<p>The Time / Temperature. You find out how many Up's and Down's there were,and the difference from the ending temperature to the beginning teperature. It increased/decreased by 2degrees celcius throughout the day. The temperature at 2pm would've been 29. or maybe it was 27. I forget.</p>
<p>*Did this section have the question of (x^2+y^2 = u^2) and (x^2-y^2 = r^2, what's u^4 + r^4 in terms of x and y?) This is the one I didn't fill in and am hoping for it to be the experimental section.</p>

</p>
<p>Yeah that's what it was.</p>
<p>What about this question:
the integer k has a 3 in the ones place, what is the ones place value of k^1459
I put 3 because it seems that anything raised to a prime the last digit of it raised is the same as its last digit.</p>
<p>the temp at 2pm was 27...3pm was 29..so 27 is the answer
i think i got 4 for the 2nd one ( i think) and 1/27 for the jar one.</p>
