Given:
Table of values.
The train travels at a constant speed.
To find:
The speed of train in miles per hour.
Solution:
From the given table consider any two points, i.e., (0.5,22.5) and (1,45).
The train travels at a constant speed. It means, there is a linear relationship between time and distance.
The average rate of change (Slope) of a linear relationship is





So, average rate of change in distance with respect to time is 45.
Therefore, the speed of the train is 45 miles per hour.
I believe what you would do is multiply $20 by 8% and get 1.6. So ten you would subtract 1.6 from 20 and get $18.40 on the book.
<u>Answer:</u>
The correct answer option is B. 0.21.
<u>Step-by-step explanation:</u>
We are to find the value of
using the law of cosines.
We know that the formula of the cosine rule is given by:

So substituting the given values in the above formula:





cos C = 0.21
