Answer:
A. In pedometer, ped comes from the Latin pedis, which means "foot."
Explanation:
Etymology is the study of the history of words. Basically, you want to find out the origins of the word. Therefore, A is the correct choice as it describes how the word "pedometer" came to be, originating from the Latin word meaning foot. Etymology is not the synonyms, definition, or pronunciation of a word and thus you can rule out B, C, and D.
Overall, either by ruling out choices or by the definition of etymology, A is the correct answer.
A. The y-intercept of the function is equal to the value of y when x = 0, so y = 8 ft

This means that the horse is already 8 ft away from the barn initially.

B. The average rate of change represents the slope of the equation. This can be calculated using the formula:
<u><em /></u>
m = (158 – 58) / (3 – 1) = 50 ft / hour
<u><em /></u>
C. Since we already have our y-intercept and slope, we can establish the line equation:
<u><em /></u>
y = 50 x + 8
<u><em /></u>
When y = 508 then x is,
<u><em /></u>
508 = 50 x + 8
<u><em /></u>
50 x = 500
<u><em /></u>
x = 10 hours
<u><em /></u>
<u><em>It takes 10 hours to reach a displacement of 508 ft.</em></u>

It is a sentence where the subject performs the action and it is stated by the Verb.
