<span>Federalism means the way of government where there are
various levels of government. As different level government system is more
accessible for general people where they can say what they want or express
their opinions about something being right or wrong. So in my opinion for the most
part Federalism is a tool for the protection against "majority
tyranny" and therefore a protection for the minority.</span>
<span>To
explain this in an example, if a state banns all the women to be employed at
any level, the federal government will intervene and stop this unjust decision,
or vice versa. </span>
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

The correct answer is A) prevent monopolies.
Financial regulatory agencies focus on preventing monopolies because monopolies can be negative in a capitalist economy.
A monopoly is when one company has almost complete control over one specific market. For example, John D. Rockefeller was considered a monopoly by many people as his company Standard Oil controlled roughly 90% of all oil created in the US during the late 19th century. This type of control by one company can have a negative effect on the consumers. This is due to the fact that the monopoly has very little competition. Since there are few (if any) companies that can compete with the monopoly, the company that has cornered the market may have the chance to raise prices as high as they want. This is due to the fact that there is no other source to get this good from. This is why the government regulates the development of monopolies.
I'd say everything can be used but only what is needed for particular patient.
