The reason I'm asking this question, is because I'm thinking about moving to Canada where I'll have more freedom and there won't be as many laws that don't make any sense.

I'm stuck with a journal problem (CMJ), but I can get past it if I can just justify that the cube of the average of three positive real numbers is less than or equal to the average of the cubes of the same three numbers.

i.e. prove ( (x + y + z) / 3) ^ 3 <= (x^3 + y^3 + z^3)/3.

I suspect it is true for any real numbers, but the problem I am working on only requires the numbers to be positive.

I am sure this is either some theorem or some consequence of some theorem. Someone with more stats/number theory experience than me, please help!

Should we just ignore them, or should a more pro-active approach be taken (though I'm not sure what!)?

Freddy the farmer has three fields. One field is an equilateral triangle, one field is a circle, and one field is a square. The square field is 75% larger in area than the triangular field, and 50% larger in area than the circular field. In order to completely fence all three of the fields, exactly 4000 metres of fencing is required.

What is the total area of all three fields, in square metres? Please round to the nearest whole number.

Something that does NOT contain any animal products.
And as I say above, something which is deemed "safe". Safe may be an arbitrary term, but none the less...on today's market there are things the consumer needs to be careful with/about.

The fertilizer can be mineral, it can be synthetic, it can be organic, or it can be a combination of all three.mentioned categories

thanks

Some people that answered my last question need to not answer this 1. If you do not know calculus don't try to answer the question. The answer is : -5 sin (5x) Jay H is getting the points. (Could that be Jay Haramy?). Next problem: S(-2Sin(Sin(2x))*Cos(2x))dx

why does this not have a similar graph to an exponential?
dy/dx=y(1-x)

Also, if you solve this, do you get the same answer as me?
problem: dy/dx=y(1-x) , y(0)=2 , y(x)>0
answer: y(x)=2e^(x-.5x^2)

I just want to make sure I am doing this right.
