Question:
The graph shows the distance in miles of a runner over x hours. What is the average rate of speed over the interval [9, 11]?
A. 2/5
B. 1
C.2
D.5/2
The image of the graph is attached below.
Answer:
Option D: 5/2 is the average speed over the interval [9,11]
Explanation:
The graph shows the distance in miles of a runner over x hours.
Now, we need to determine the average rate of speed over the interval
The x-axis represents the time taken.
The y-axis represents the distance.
To find the average speed, let us use the formula for speed which is given by
Thus, substituting the coordinates and
, we have,
Hence, the average speed over the interval is
Vectors are elements of the vector space, and they can be illustrated by diagrams.
<h3>How to draw the vector 2u - 1/3v</h3>The vector expression is given as:
2u - 1/3 v
Split the vector expressions, as follows:
See attachment for the graphs of y1 and y2.
Next, we have:
So, we have:
The above expression means that, we add the vectors y1 and y2 to get vector y
