You seriously cannot answer this one yourself?

How do you manage to use a computer?

the slope is whatever it is.  If it's a fraction so be it.  So yeah, it would be 1/7 x

yeah it looks like it... what is this supposed to be?

59x(4x-82) = 154 ?

(59x)(4x) - 82 = 154 ?

something else?

\(x+2i - y = i y - i 3x\\ (3i +1) x + 2i =y(1+i) \\ y = \dfrac{(3i+1)x + 2i}{1+i}\\ y = \dfrac{(2+4i)x + (2+2i)}{2} = (1+2i)x+(1+i)\)

Now if both x and y are real you can apply EP's answer.

\(|t+2i\sqrt{3}||6-4i|=26\\~\\ |6-4i| = \sqrt{36+16} = \sqrt{52}=2\sqrt{13}\\~\\ |t+2i\sqrt{3}| = \dfrac{26}{2\sqrt{13}} = \sqrt{13}\\~\\ t^2 + 4\cdot 3 = 13\\ t=1\)

well you've given us... nothing... so I don't know what sort of answer you expect.

Overall the problem seems simple enough.  Each person pays a price to attend each show.

In some way estimate the number of people that will attend each show and multiply this by the price.

Add everything up.

In one of the Feynmann lectures he goes deeply into why a drop of oil on a water surface has all the colors it does.

It's one of the best explanations of the quantum nature of electromagnetic radiation there is.

I don't know if that link will cause this to go into moderation limbo or not... we'll see

It does.  Just youtube Feynmann lectures, and look for Part 1 - Photons Corpuscles of Light

this site has some pretty annoying bugs w/regard to posting links
