If you can help me understand this.. i basically understand the examples in my book but when it comes to problems I run into factoring problems.
Find the zeros algebraically.
#1 f(x)=2x^4-2x^2-40
Then I also have to analyze it.. in these problems..
#2 f(x)=2x^4-6x^2+1
#3 f(x)=x^5+3x^3-x+6

these have to be done with a graphing utility to approximate the zeros and then check by calculating.. another problem my graphing calculator i s not very accurate.. it is not broken not old.. it just is not very exact.. it jumps when i have it on trace mode.. from like x=0.5 to next is x= -0.8 and i am wanting to find X=0 .. the only way to get to that is to not use the trace but still then it only gives me one decimal place when i should be getting 3..
if you know how to fix that then i will be happy.. but if you don't think it is much of a problem that is ok.. but i keep on getting the wrong answer for the 3 decimal points.

I have recently come up with a theory as to how astrology affects us. First of all, astrology can be the most grounded of all sciences as it is based on our universe and planets..i mean how much more grounded can you get?

What my theory is that: astrology is basically how the position of planets affect our mood and events surrounding us. each planet has a gravitational pull- some sort of magnetic power. Our brains have neurons, which also have electric charge and my theory was that depending on the position of the planets, our brains/neurons feel the pull of their gravity/magnetic power.

What do you guys think? I mean I was not able to write it very clearly, but that is the gist of it.

Thanks!

Since the earth is spinning there is a part of the force of gravity that is used for the centripetal force.

If we stopped spinning i would assume we would feel heavier. Would we notice it?

I think in the far future a meteor will hit the the earth but I think it won't be in our lifetime. Our the sun will fade away and the ice age would be back and our earth will freeze over. I know this sounds crazy but I do think it's possible. I'm saying like in a million years there's a chance but in our lifetime I don't think but you never know.

1. Is this expression false? Explain why or why not.
(square root of 2) + (square root of 6) = (square root of 8)

2. Find the area of the rectangle.
Top: square root of 3 + square root of 5
Right Side: square root of 3 + square root of 5
**This is not a typo. I'm supposed to find the area of the rectangle but it seems to me like it's a square. Please help explain.
