Answer:
The graph of the function rule will be a line segment connecting (0,2) and (40,22) as shown in the graph below.
Step-by-step explanation:
Given:
The function rule representing the total cost of ride and number of miles traveled is:
Now, the maximum value of is 40.
So, the maximum cost of ride is given as:
So, the graph of the given function rule has a domain between 0 and 40 and range is between 2 and 22.
The graph is shown below.
Answer:
The improve in speed is 3.9334 words/min
Step-by-step explanation:
we will find speed at both occasions and then we can subtract them
First test:
total number of word =694
total time =15 min
we know that
speed = (total number of words)/( total time)
now, we can plug values
speed is
word/min
word/min
Second test:
total number of word =753
total time =15 min
we know that
speed = (total number of words)/( total time)
now, we can plug values
speed is
word/min
word/min
So, improve in speed is
word/min
