It's in an answer of a question. It's stated there that genes can only lose information over replication (and therefore there must be something else that created all these species). I highly doubt this by the way. The original answer is here (by answerer 12)

6) For what values of k is 5x+ky=3 parallel to 2x-3y? For what values of k are the two lines perpendicular?

13) Remembering that for even functions f(-x)=f(x) and that for odd functions f(-x)=-f(x) show whether the following functions are even, odd or neither
a. y=x^4
b. y= x-x^4
c. y= 1/((x^2) -4)
d. y= -2(x^3) +4x

21) Simplify each of the following
a. ((2/3)x^(-3))(15x^7)
b. (x^3)((2yz^2)^3)
c. ((3(x^3))(4(x^5))) / ((x^2)^3)
d. ((2(y^4))((3(y^2))^2)) / ((y^3)^4)
e. (3(a^(-2))(b^3))^(-3)

22 )Simplify by removing all possible factors from the radical
a. sqroot (9(a^8)b)
b. cubed root (24(a^4)(b^8))
c. sqroot (75 / (a^6))

23) Factor each of the following completely
c. 4(x^16) -9(y^6)
d. 6(x^2) + 7x - 20
e. 3(x^2) -5x + 2
h. (x^2) +4x + 4 + 9(y^2)

Additional Details:
I'm not really just wanting answers.. as it says i just need someone to remind me how to do these... so i can do them.. i have already learned all this just forgotten how to do it

Is there any reason they would turn off wind turbines in a wind field due to efficiency? I know the fans are braked if winds exceed a certain velocity and possibly due to energy needs they may stop some of them. However in a debate with a friend he argued that it would be more efficient and produce more energy to have fewer running versus more. This is counter intuitive can someone shead some light on this topic. I refuse to accept my friend logic.
