The name and chemical symbol of the elements are
- Carbon = C
- Lead = Pb
- Antimony = Sb
- Sodium = Na
- Aluminum = Al
<h3>What are chemical symbols?</h3>
Chemical symbols are which are used to represent the elements in the periodic table.
The chemical symbol assigned to elements are usually an abbreviation of the name of the element or the Latin form of the name.
The name and symbol of the given elements are as follows:
- Carbon = C
- Lead = Pb
- Antimony = Sb
- Sodium = Na
- Aluminum = Al
The chemical symbols are used frequently in writing the formula of compound formed from the elements. For example, the compound sodium aluminate which contains sodium, aluminum and oxygen is written in a simplified form as: NaAlO₂.

Answer:
Vertically Shrunk by a factor of 1/6
Explanation:
Parent Formula: f(x) = a(bx - c) + d
<em>a</em> - vertical shrink/stretch and x-reflections
<em>b</em> - horizontal shrink/stretch and y-reflections
<em>c</em> - horizontal movement left/right
<em>d</em> - vertical movement up/down
Since we are only modifying <em>a</em>, we are dealing with vertical shrink/stretch:
Since a < 1 (1/6 < 1), we are dealing with a vertical shrink of 1/6.
Since a > 0 (1/6 > 0), we do not have a reflection over the x-axis.
To find the mean of a number of numbers, First you add them up.
9.99 + 10.01 + 9.97 + 10.8 = 40.77
Then, you divide the result by how much numbers you have (in this case 4)
40.77 / 4 = 10.1925
So, the mean value is 10.1925.
The deviation is the difference between the number and the mean.
(number - mean = Average deviation)
So you get:
9.99 - mean = 9.99 - 10.1925 = -0.2025
10.01 - 10.1925 = -0.1825
9.97 - 10.1925 = -0.2225
10.8 - 10.1925 = 0.6075
Now to find the Average deviation, you do the same steps as finding the mean. Add them up, and divide by 4 (because there is 4 numbers)
P.S. Negative numbers become positive.
0.2025 + 0.1825 + 0.2225 +0.6075 = 1.215
1.215 / 4 = 0.30375
So, the Average Deviation is 0.30375
Hope this Helps :)
Cornea - lens - retina
Explanation:
The pathway of light into the eyes goes from the cornea through the lens where it gets focus on the retina and optic nerves picks up the signal where the brain interprets the image. The eye is the organ of sight.
- When light rays from objects hits the human eye, it goes through the cornea first. In the cornea the image begins to form and using the pupil located in it the amount of light that enters is regulated.
- From the cornea, light goes into the lens. The lens allows for the rays to focus on the retina.
- The retina receives the rays and the image forms .
