yes, this is what i meant justlook......
i kow she is from poland but would like to know which part :-)
mikka where are you from? :-)
Is there a possibility to send an e-mail to a member or the staff?
thanks
it's not the scam guys. you are transferred to the website with links to sponsors but you don't have to click on them. just click on the stomach, that's all. it's one of the biggest charities in poland, so guys it's not a scam.
there are no pop-ups. you just click on the stomach, are transferred to another website - it says thank you ang gives the name of the sponsor but you DO NOT have to click on it.
thanks
Want to help to feed polish childeren?
Go to www.pajacyk.pl and click on the stomach. it takes only a few second (you can do it only once per day)
thanks guys
ok, here you go
ok, got it. however difficult for me to expalin.
check:

not the sane problem but might help
I'm getting 4sqrt2 but also imaginary numbers.
is the question about the triangle correct? haveing some problems with it :-(
difficult to recomend anything, at least for me. But i'm sure here are some guys who will be able to help.
4. canal
he gave 35*35 as an example. he said it works with 35 but asked why :-)
Raulito this we already know the question was about proving it.
if it's -7x^2 the function has a maximum (coordinates: (1/7; 1/7)
if its (-7x)^2 it wil have minimum
x= 1/7
you just leave it like this. i don't think you have to change it into decimal.
this is what i came up with:
(10a + 5)^2 and a<10
100a^2 + 100a + 25 as you see you will always have to add 25.
100a^2 + 100a = 100a(a + 1) so you multiply tens by tens plus one, by putting it in front of 25 you "multiply" by 100.
y1 = m1x + C1
y2 = m2x + C2
the lines to be parallel: m1=m2
Line 1 passes through (2; 3):
y1=m1x + C1
3 = 2m1 +C1
line two:
3x-2y+12 = 0
-2y=-3x-12
y=3/2x + 4 m2 = 3/2
m1=m2=3/2
line 1:
3=2*3/2 + C1
3=3 + C1
C1=0
equation:
y=3/2x
what do you mean by A[0,2]?
i can't do it
do not know how to put it here :-(
5. i^(-4k+3) = i^-4k * i^3 = 1/i^4k * (-i) = 1/ i^2^2k * (-i) = 1/-1^2k * (-i) =
1/1^k *(-i) = 1*(-i) = -i
solved 8 but dont know how to put it here :-(
how to paste equation from MS word? i have saved this bloody thing as a jpg try to paste it here but it does not work :-(
3. A` = [1,3] ?
4. [1,2)?
5. -i
n(AUB)=n(A) + n(B) - n(AandB)
40 = 18+24 - n(AB)
n(AB) = 2
probability that the firsy magnolia is north is 1/2
probabbility that the second is south 1/2
different side: 1/4
reversed *2
final: 1/2
mathsyperson, you are saying that there are nine trees in the row which is not the truth!! remember that we have to choose the correct side first
jkiller you were finding the number of ways not the probability
guys in my opinion we also have to remember that the trees have to be put on the same side of the road. here probablity is 1/2 * 1/2 = 1/4
in my opinion this is what we should start with.
