To find the values of a and b, we can use the given information about the function f(x) and its derivatives at x = 0.
First, we know that the value of f(0) is 1, which means that when we plug x = 0 into the function, we get f(0) = 20 + a0 + b*0^2 - 0 + 2 = 1. Solving this equation for b, we get b = -1.
Next, we know that the derivative of the function f(x) at x = 0 is ƒ'(0) = 1. The derivative of a polynomial function is given by ƒ'(x) = 2x + ax + bx^2 - 1. Plugging in x = 0, we get ƒ'(0) = 20 + a0 + (-1)*0^2 - 1 = 1. Solving for a, we get a = 1.
Therefore, the values of a and b are a = 1 and b = -1. The sum of these values is a + b = 1 + (-1) = 0.
I would say your answer is “B” but i’m not 100% sure!
As for the main disadvantage: the media need revenue. Revenue tends to be tied to reporting more dramatic events. In absence of truly dramatic events, the media develop tendency to "dramatize" (especially when it gets to political events). As a result we are observing what is usually called polarization. Media to the left and right of the center will tend to amplify certain aspects of reality. Viewers will then tend to focus on sources matching their own (political) affinities. Media source thus develop their own virtually separate audiences. A cycle of polarization emerges.
This is obviously bad for democracy which is based on the principle of educated decision making by every citizen. Citizenship has been more and more polarized and their decision making on issues delineated by political boundaries. Clustering is a problem. For instance, someone who cares about protecting the environment faces a decision whether to join a cluster of political views that include environmental protections (but also other views lumped together with environmentalism by the process of polarization), or completely stay away from that topic. That is bad for democracy.
The moment you see a person pronounced guilty vs. not-guilty by a vote that almost exactly splits down by the political affiliation of the voters, we know we are having a problem.
NOUN, the state of being in short supply.
Answer: n mid-December 1940, Roosevelt introduced a new policy initiative whereby the United States would lend, rather than sell, military supplies to Great Britain for use in the fight against Germany. Payment for the supplies would be deferred, and could come in any form Roosevelt deemed satisfactory.
