Both the coal and the petroleum are fossil fuels, and both of them produce lot of energy when burned or through combustion. They have their positives and negatives.

The coal is primarily extracted on land, so it easier to get to. As a positive is that the coal produces a lot of energy, thus it is capable to run the industry without any problem, until there are reserves that is. On the other hand, the extraction of coal is damaging the environment in the surrounding area, and it is also the fossil fuel that releases the most carbon dioxide into the atmosphere, thus it is a very heavy polluter.

The petroleum is primarily extracted from the sea, so it is harder to get to. As a positive is that the petroleum releases a lot of energy, it is easy for usage, and it is very efficient, so it is capable of running the industry until there are reserves of it. A negative from the petroleum is that its extraction is badly damaging the environment in the seas, and it also causes lot of pollution (though much less than the coal) to the air when burned. Another negative thing are the spills of it, as once it gets spilled into the water or on land, it manages to kill off pretty much everything alive.

Please show steps and explain

Answer:

$\frac{n-6}{3n} = \frac{n-5}{3n+1} \\\\\frac{n-6}{3n} - \frac{n-5}{3n+1} = 0\\\\\frac{(3n+1)(n-6)-3n(n-5)}{3n(3n+1)} = 0\\\\(3n+1)(n-6)-3n(n-5) = 0\\\\3n^2-18n+n-6-3n^2+15n=0\\\\3n^2-3n^2-18n+n+15n-6=0\\\\-2n-6=0\\\\2n+6=0\\\\2n=-6\\\\n=-3$

You can solve this equation by applying the zero product rule.

Firstly, you equate the expression to 0 in order to combine both fractions into one. As shown in Step 2, you find the LCM of both fractions and multiply accordingly. In this case, the LCM of both fractions is 3n(3n+1). Hence you cross multiply.

Next, you eliminate the denominator in order to solve the equation more conveniently. As you multiply the fraction by the denominator on the LHS, you do that to the RHS as well to maintain balance. 0×3n(3n+1)=0, hence Step 3.

Then, you expand the parentheses using the distributive law of multiplication, resulting in a quadratic equation.

Lastly, you solve the quadratic equation.

The answer is n=-3

Which of the following is the learned response to a conditioned stimulus?

Anni [7]

The learned response to a conditioned stimulus is: D. CR.

<h3>What is classical conditioning?</h3>

Classical conditioning can be defined as a learning process which typically involves repeatedly pairing two stimuli, which include the following:

Conditioned stimulus.

Unconditioned stimulus.

In classical conditioning, a response which is at first brought forth by the second stimulus would later be brought forth by the first stimulus alone.

This ultimately implies that, classical conditioning is a process through which a living organism can learn how to associate stimuli and as a result anticipating events.

In this context, we can infer and logically deuce that the learned response to a conditioned stimulus is conditioned response (CR).

If (x + yi) + 6i = 2, what is x + yi?

CaHeK987 [17]

The answer is: " 2 − 6i " ; or, write as: " -6i + 2 " .
_____________________________________________
Explanation:
_____________________________________________
Given: <span>(x + yi) + 6i = 2 ; What is: (x + yi) ?
_____________________________________________
Subtract "6i" from EACH SIDE of the equation ;
_____________________________________________
x + yi + 6i </span>− 6i = 2 − 6i ;
_____________________________________________
to get: x + yi = 2 − 6i ; or, write as: -6i +2 .
