The Institutional changes between the 1960s and 1980s shifted the public policy from emphasizing public interest to upholding and satisfying the regulations. Among the greatly affected was the educational system. The structures of the different learning institutions were changed to accommodate dynamic market models and work around the expected outcomes of learning.
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

Answer:
1775–1830
U.S. Indian policy during the American Revolution was disorganized and largely unsuccessful. At the outbreak of the war, the Continental Congress hastily recruited Indian agents. Charged with securing alliances with Native peoples, these agents failed more often than they succeeded. They faced at least three difficulties. First, they had less experience with Native Americans than did the long-standing Indian agents of the British Empire. Second, although U.S. agents assured Indians that the rebellious colonies would continue to carry on the trade in deerskins and beaver pelts, the disruptions of the war made regular commerce almost impossible. Britain, by contrast, had the commercial power to deliver trade goods on a more regular basis. And third, many Indians associated the rebellious colonies with aggressive white colonists who lived along the frontier. Britain was willing to sacrifice these colonists in the interests of the broader empire (as it had done in the Proclamation of 1763), but for the colonies, visions of empire rested solely on neighboring Indian lands. Unable to secure broad alliances with Indian peoples, U.S. Indian policy during the Revolution remained haphazard, formed by local officials in response to local affairs.
Europe has been going though deforestation since the neolitic times.
In North America deforestation can be found for example in Canada
South America is undergoing deforestation- for example in Bolivia
Asia is definitely undergoing deforestation- for example in Indonesia
so the correct answer is: none of the above!
