�t�e�s�t/619467: i know that a squared plus b squared equals c squared and I understand that (here is a problem that i made up) if side A is 5 feet and side B is 12 feet that it would come out to 144 + 25 which equals 169 and that that is side C and the hypotenuse but then, do you add 169 together or multiply it together but Im confused what to do after you add side A and B together. Please help. Thanks so much

Pythagorean-theorem/619429: thank you for your assitance-- i have had a llittle trouble in firguring out these type pythagoreum problems-- i am in my math book from school--i am older soon returning to school- so again thank you for saving me time from sitting here all day, literally trying to guess!! (charuethornhill@att.net) thank you again.
ok it says: there are two vertical poles of length 6 feet and 8feet stand 10 feet apart. a cable reaches from the top of one pole to some point on the ground between the poles and then to the top of the other pole. where should this point be located use 18 feet cable, the answers are 1.2 feet or 7.5 feet, i am aware of the P thereom thing, but still cannot figure out what going to produce 1,2 or 7.,5 thanks.

Answer 389668 by scott8148(6628) on 2012-06-10 16:03:01 (Show Source):
You can put this solution on YOUR website!the 18 ft of cable is the sum of the two hypotenuses of the triangles formed when the cable is strung
if the cable is anchored x ft from the 6 ft pole ___ sqrt(6^2 + x^2) + sqrt[8^2 + (10 - x)^2] = 18
rather than solving this formidable equation; I would suggest substituting the choices to find the solution(s)
___ there may be more than one
also; since the question didn't specify the location, you may be looking for 10-x rather than x
good luck going back to school

Answer 389541 by scott8148(6628) on 2012-06-09 20:24:04 (Show Source):
You can put this solution on YOUR website!the smallest value in the ratio is half of the largest value
this is also the relationship between the longest and shortest sides

Permutations/619244: in how many ways can a four letter set of words be formed using the vowels, a,e,i,o,u, assuming that repetitions are allowed?
n = 5
r = 4
nCr = 5!/r!(n-r)!
5! = 120
4! = 24
n-r = 1
nCr = 120/24*1 = 5
Is the problem with the 5?
This can't be right

Rate-of-work-word-problems/619220: Joe can do a job in 12 days after he has worked for 4 days he is joined by Casey and it takes them 2 days working together to finish the job. How long would it take Casey to do the whole job herself.
THIS IS WHAT I DID
Joe time + Casey time = both working together, but they only do 1/2 the job in a day
4(1/12) + 1/X = (1 - 4/12)/2
I get an answer of no solution so my problem must be set up wrong. Can you help?

Answer 389475 by scott8148(6628) on 2012-06-09 12:58:15 (Show Source):
You can put this solution on YOUR website!Joe finished 1/3 of the job before Casey came, so they finished 2/3 together
(2/12) + (2/C) = 2/3
in the 2 days they work together, Joe does another 1/6 of the job (so he does 1/2 total)
___ this means Casey does 1/2 of the job in 2 days

Trigonometry-basics/619215: I am using a texas instrument TI-84 Plus calculator, the problem I would like answered is, find the value of the indicated trigometric function.
Find tangent theta, given secant theta = 1.3698
find tan theta, given sec theta = 1.3698

Answer 389469 by scott8148(6628) on 2012-06-09 12:29:18 (Show Source):
You can put this solution on YOUR website!the secant is the inverse of the cosine
1/1.3698 will give you cos(theta)
there is also an identity ___ tan^2 = sec^2 - 1
either way should give the solution
