y is bigger than or equal to 0

x is smaller than or equal to 3

3x + 2y is bigger than or equal to 6

2y is smaller than or equal to x + 2


What are the coordinates of the 4 vertices's of the feasible region?

The feasible reason is:

left of
x is smaller than or equal to 3

above
y is bigger than or equal to 0

To the right of
3x + 2y is bigger than or equal to 6

Below
2y is smaller than or equal to x + 2


Please Help

Evolutionists are telling us that we came from ape and after billion of years in the process we became man.
They also told us that in the begining, life forms in earth originated from bacteria that leaves in the water and transformed into another life form and so on until the multitude of living species evolved.
Evolutionists also tell us that EVOLUTION is CONSTANT CHANGE.., now, my question is WHAT EXACTLY WILL BE OUR CONFIGURATION AFTER ONE BILLION YEARS AHEAD IF THERE IS CONSTANT CHANGE? is evolution a fact or a lie?

Did anyone see the article on rethinking the paranormal last night on MSN? I saw the picture for it but didn't read it, and I can't find it now. Does anyone have a link to it? Thanks!

Looking at all the facts, the species Homo Sapien (human) seems to have the longest record by far for tending/raising their own offspring.

Most animals in the wild only 'put up' with their children until they are sexually mature.

Humans can sexually mature anywhere from 9-15 years of age.

How is it then, it that case, that:

1) We keep raising our children so much longer than biologically necessary?

2) Most women become fertile again either immediately or soon after giving birth, which suggests that our biological law requires us to produce one offspring at least once a year. How on Earth would a single human (or even a partnership of humans) raise and tender to all of their children if they had at least one every single year?

Ok, when you apply shoe polish, shoes become matt (!) first, and only when you've polished them with a brush, they become all shiny. Is it because of the molecules or what? :)))

1) Looking at the equation for intensity I=4(I sub o)cos(pi*d*y/wavelength*L)^2, as you increase the distance between the screen and the 2 slits why does intensity increase?

2) Also if you increase the slit width, by the equation, the intensity doesn't change. Intuitively I thought it should change intensity somehow.

3)If you increase only one slit width of the two slits, the intensity should be skewed somehow. How is it changed?

I have some sample problems to study with, but I can't figure this one out.

Solve this equation:
e^x-12e^-x -1=0

Please show me the steps.

How many kilometers will the car travel in 4 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.
