People say that they are controlling the rattlesnake population, which in fact they are decimating the population. They believe that rattlesnakes has no part in the ecosystem, which is entirely false. If they like it so much, why not just raise them for that purpose and then leave the wild ones alone. Rattlesnakes are both important as predators and prey. They help maintain balance in the rodent populations.

I need to prove that if A and B are matrices such AB and BA exist, and AB is symmetric (so AB = (AB)transpose ), show that AB=Ba.

So far I can prove that AB and BA have the same size, but I can't figure out how to prove that they have the same entries.
Proof of size:
A is m*n, B is n*p. So AB is m*p, but since BA exists too m must = p. So now A is m*n, and B is n*m. This leads to AB being m*m and BA being n*n. And since AB=BA m must = n so all of the mentioned matrices must be n*n in size.
now i just need to prove that the entries of AB and BA are the same.

If it is true (now) that Pi has infinite decimals, then does that mean you can never know EXACTLY what the circumference of a circle is? (2(Pi)r).
Yet you can draw a circle that has an exact length? Or take a string of known exact measurable length and make a circle out of it.

What am I missing?
