Ahhhhhhhhhhhhhhhhhhhhhhhhhhhh
The supply curve will be composed of the following points
(10, 1000) from the statement: 1000 shoes in the market at $10
(25, 1200) from the statement: 12000 shoes at $25 per pair
(40, 1400) from the statement: <span>$40 per pair, the existing firms increase production to 1400 each</span>
<span>The membrane lining the interior of the thoracic cavity is called the 3. parietal pleura.
Thorax is the part between the neck and the abdomen. Parietal, in anatomy, refers to the walls of a hollow structure, such as the thoracic cavity in the human body. Pleurae are the sacs surrounding your lungs.

Arguments used in defending against a criminal would be 1) Infancy 2) Duress 3) XYY chromosome (makes men men aggressive), 4) Necessity, and 5) Entrapment (forced to commit a crime).
The first thing you have to realize is that
tangent is the
slope of a curve on a given point. You can solve for the slope by finding the derivative of the given function. So:

Next use
product rule (I recommend watching videos if you're confused):
![= [sin(x)] + [x*cos(x)]](https://tex.z-dn.net/?f=%3D%20%5Bsin%28x%29%5D%20%2B%20%5Bx%2Acos%28x%29%5D)
Next substitute you x-value (π/2) into your derivative:
![= [sin( \frac{ \pi}{2} )] +[ \frac{\pi}{2}*cos( \frac{\pi}{2})]](https://tex.z-dn.net/?f=%3D%20%5Bsin%28%20%20%5Cfrac%7B%20%5Cpi%7D%7B2%7D%20%29%5D%20%2B%5B%20%5Cfrac%7B%5Cpi%7D%7B2%7D%2Acos%28%20%5Cfrac%7B%5Cpi%7D%7B2%7D%29%5D%20%20)


So our slope at π/2 is 1. Next we use our slope-form and substitute our given value and solve for y-intercept (algebra-stuff)


So we get our equation:

So our answer is E
