The image below shows where coal deposits are found in the United States. Explain how these coal deposits are energy sinks and c

ould be potential energy sources.

Rudik [331]3 years ago

Answer:

It is a little bit trivial:

As we know:

Energy sink: is anything that uses energy.

Energy source: is anything that produces energy.

How the caol deposits can be energy sinks? well, you want to extract the coal from those deposits, and to do it, you need to "use energy" (the type of energy can depend on the extraction method, for example, if you use a pickaxe to extract the coal, you are using mechanical energy)

These coals are potential energy sources because coal is an energy source, potential means that, given some circumstances, something can transform into other things.

So potential energy source in this situation means that those coal deposits can be potential energy when we extract the coal and use it as an energy source.

The graph of g(x) is obtained by reflecting the graph of f(x)=2|x| over the x-axis.
Lera25 [3.4K]
Answer: Choice C) 
g(x) = -|2x|

You get this answer by simply sticking a negative out front of the original function. In other words, g(x) = -f(x) or more technically, g(x) = -1*f(x).

The negative will flip every y coordinate from positive to negative (or vice versa)

You'll also use the idea that |2x| = 2|x|. The two can be pulled out since we can say |x*y| = |x|*|y|
So |2*x| = |2|*|x| = 2|x|

Find the missing value when given the modulus.
kolbaska11 [484]

Solving the complex number, we get the value of the missing value that is ‘a’ = -6

We  have been given the expression as

          |a – i| = √37          (1)

Which is an expression of complex number. The general expression of complex number is given as

    z = x + iy

 where x is the real part and iy is the imaginary part

To find the modulus value, the formula is given by,

  |z| = |x + iy|

   |z| = √[(real part)2 + (imaginary part)2]

 |z| = √(x2 + y2)

According to the question, |z| = √37         (2)

Equating equation (1) and (2), we get

√(a2 + 1) = √37

(a2 + 1) = 37

a2 = 37 – 1

a2 = 36

a = √36

a = ±6

Now value of a can be 6 or -6. We have been given that the modulus is in third quadrant.

Hence the value will be negative. Therefore, the missing value will be -6.

Greeley [361]
Hey - I need the graph to be able to help you. If you're on a computer, and it's a PC, you can use the snipping tool found in the start menu. Snip the graphs, then copy and paste them into a new question. If you're on a mac, command+shift+4 will get you a screenshot. Screenshot the graphs, go to finder, go to desktop, find your screenshot, then copy and paste it into a new question. :)

Sorry I can't help but I need the graph. :)
