P could equal +/- 1, +/- 2, +/- 11, +/-22
q could equal +/- 1, +/-2
so roots could be p/q = +/-1 , +/- 1/2 , +/- 2, +/- 11/2 , +/- 11, +/-22
That is the third choice.

Step-by-step explanation:
4 trillion pounds.
1 gigawatt-hour is equal to 1,000,000 kilowatt-hours.
Out of our 4,000,000 gigawatt-hours, 50% of it comes from coal; this is 2,000,000 gigawatt-hours.
2,000,000(1,000,000) = 2,000,000,000,000 (2 trillion) kilowatt-hours.
Since each kilowatt-hour is 2 lbs of carbon dioxide, 2 trillion * 2 = 4 trillion lbs of carbon dioxide.
Answer:

Step-by-step explanation:
Use the Product Rule for derivatives, which states that:
In the function we are given,
, we can break it up into two factors: -x is being multiplied by cos3x.
Now, we have the factors:
Before using the product rule, let's find the derivative of cos3x using the chain rule and the power rule.
Now let's apply the product rule to f(x) = -xcos3x.
Simplify this equation.
Multiply x and 3 together and remove the parentheses.
Therefore, this is the derivative of the function
.
