<p>They said letters can be repeated… so I put 26^5(10)</p>

<p>it was 26^5 * 10. Since you are allowed to repeat letters, you can pick any of the 26 letters, 5 times. Thus 26<em>26</em>26<em>26</em>26 or 26^5. Then it’s 10 digits between 0-9 to choose from so it’s 26^5*10. It was 7.5 since it was asking for the height of the triangle created by the two intersecting lines. That happened to be half of the distance of the width since of line F</p>

<p>it said the letters can repeat. so it was 26^5(10) one.</p>

<p>****tt you right damnit</p>

<p>so wait was the anser to the last one E? The one with the square root of r/s…</p>

<p>The one with the letter and number combination said you could repeat letters. So for each of the 5 letters there are 26 different possibilities. 26 x 26 x 26 x 26 x 26 x (amount of numbers 0-9) so 26^5(10)</p>

<p>"anybody get (26)^5(10)? or maybe im high on something. lol. "</p>

<p>THAT WAS the asnwer. I did change it and got it right.</p>

<p>It said letters CAN Repeat
so do it this way</p>

<hr>

<p>6 spaces
first 5 are letters, last is a number
therefore</p>

<p>26 x 26 x 26 x 26 x 26 x 10 (10 represents 9 digits)</p>

<p>What was the letter for the 5/2 sine problem?</p>

<p>oh yeah you’re right! thats why i changed my answer to 26^5, because i saw that <em>letters can repeat</em></p>

<p>Oh what about the one at the top of the page where it was a diagram and there was a point F that onnected the midpoints of the two sides and then a line is drawn from B to F, what is the distance from the one intersection to the side? Anyone know what Im talking about? I put 7.5 i think</p>

<p>^ yup! 10 chars</p>

<p>7.5 seems to be the general consensus</p>

<p>for that one i think i got (10) (26)(25)(24)(23)(22) or something, i forget. i just remember it looked like that.</p>

<p>for the last math question, i chose the (E) answer. the one that had to do with R and S. </p>

<p>for the x-|x| did you guys get always sometimes negative? i remember putting always zero, but i realized thats wrong when you plug in any negative number :P</p>

<p>i got 5 for the tent, 7.5 for the distance, and 88 degrees for the angle. it was 132 divided by three, which is 44. then you took 48+44 and subtracted that from 180 to get 88 degrees.</p>

<p>I think i got that one wrong… i put just the length of the very left side lol</p>

<p>^ never positive</p>

<p>never posotive for x-abs(x)</p>

<p>For the x-|x| I put never positive</p>

<p>x - |x|</p>

<p>is never positive</p>

<p>which one is not true
a=c?</p>

<p>The last one was E as for as I remember. I plugged in number accordingly and it came out to that.</p>

<p>A= B
C^2= D
C= sqrt(B)</p>

<p>ergo, A doesn’t equal C</p>

<p>and x is NEVER positive</p>
