Answer:
B. (-5,-2)
Explanation:
When a point is reflected across y = x, we only need to switch the x and y values of the old coordinates to get the new ones. S is at (-2,-5), so by switching the x and y values, we can find that the S' is at (-5,-2).
Answer:
See Explanation
Explanation:
The question is incomplete as the value of s(t) is missing;
However, the following explanation will guide you;
I'll continue my explanation with the following assumption that:

Required
Determine the velocity at t = 8
To do this; first calculate s(t) by substituting 8 for t in 




Next, is to calculate the velocity by dividing s(t) by t where t = 8
i.e.

Substitute 8 for t

Substitute 72 for s(8)


<em>So: all you need to do is first calculate s(8), then divide the resulting value by 8 to get your result</em>
The processes of extracting and separating gold in remote regions often result in environmental contamination with Cyanide (Option B).
<h3>What is cyanide?</h3>
Cyanide is a substance that contains a group formed by Carbon and Nitrogen forming a strong chemical bond (C≡N).
Cyanide can be very toxic when forms soluble salts (e.g., sodium and/or potassium cyanide).
Cyanide was used as a chemical compound during gold extraction, thereby generating environmental contamination.

With the ocean providing over half the oxygen we breathe and being a major source of food for the world’s population, there is a critical need for action and we all have the ability to make change.
Each year, at least eight million tonnes of plastics flow into the ocean — which is equivalent to dumping the contents of one garbage truck into the ocean every minute. If no action is taken, this is expected to increase to two per minute by 2030 and four per minute by 2050.
It’s sad to look at this picture and NOT look at how hurt sea animals are being hurt, how this WILL affect us in the near future, maybe even affecting us right now and we are too blind to notice. It’s painful to think of these things because sooo much is being lost. I hope people can open there eyes and realize the damage they are causing.
