To solve this question, you need to do 421 divided by 9.
421 divided by 9 will get you a long number, which is 46.7777778.
Round your number up by the hundredths place. You will get 46.78.
The average speed in miles per hour would be 46.78 MPH.
Answer as an inequality: 
Answer in interval notation: [2, 7]
==========================================================
Explanation:
The range is the set of all possible y outputs of a function.
The lowest point occurs when y = 2
The highest point occurs when y = 7
The range is the set of every y value between 2 and 7, including the endpoints.
The range as an inequality is 
It is equivalent to [2, 7] in interval notation. The square brackets include each endpoint.
Answer:
Step-by-step explanation:
<u>For visible light:</u>
-We can see it. We use visible light to see everything around us, with our eyes at least.
-Visible light has a lower energy than UV light. UV light is what gives us sunburn.
<u>For both:</u>
-They are both forms of electromagnetic radiation (light). They are simply at different energy values and wavelengths. Our eyes can only see the visible part of the spectrum, hence why it is called the "visible" part.
-They are both emitted by the Sun. The Sun lets off many types of radiation.
<u>For UV light:</u>
-UV light is very high in energy relative to visible light. Visible light doesn't give us sunburn, but UV light will. This is what we use in tanning beds.
-UV light cannot be seen with our eyes because it does not fall into the same category as visible light.

It’s the same as 12 plus 10
I think the answer would be 28. Hope this helps!
