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)

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

THAT WAS the asnwer. I did change it and got it right.

It said letters CAN Repeat
so do it this way

_ _ _ _ _ _

6 spaces
first 5 are letters, last is a number
therefore

26 x 26 x 26 x 26 x 26 x 10 (10 represents 9 digits)

What was the letter for the 5/2 sine problem?

oh yeah you're right! thats why i changed my answer to 26^5, because i saw that *letters can repeat*

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

^ yup! 10 chars

charlieharper · 10-24-2009, 02:27 PM

7.5 seems to be the general consensus

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

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

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

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.
