Please explain to me as though I am a layman, I came across an article in which the noble laureates of last year had proved that beta function can be negative, but I didn't understand how.
P.S. I am a 16 year old studying in class 11.

b/c i need to keep the leaves alive and intact as long as possible.

The problem is x^2=5x+2.
The answer that I came up with is
x=5+/-sqrt 33/2.
The question is-how do I graph that? Or is there a separate formula used for this?

The above site gives the diagram to the problem that I am working with.

It shows three blocks attached by cords that loop over frictionless pulleys. Block B lies on a frictionless table; the masses are Block A = 6.00 kg, Block B = 8.00 kg, and Block C = 10.0 kg. When the blocks are released, what is the tension in the cord at the right?

I tried setting this problem up so that I subtracted my right tension equation (or atleast what I thought was my right tension) from my left tension equation, and it came out to a really small number. I've been attempting several ways and I just have no idea how to do this. Any help would be appreciated very much!!

Do Judaism and Islam allow use of porcine derived medical products?
Do Jews and Muslims, those who believe that swine are unclean, accept medical treatments and products that are derived form swine? Small intestinal submucosa and collagen from pigs, as two examples, are used in human medicine treatments. Do their dietary laws include prohibition of this as well? Also, do Hundus refuse bovine-based products based on their reverence for cows?
