Answer: 46.53
Step-by-step explanation:
0.99 x 47
Because 21 is more than 1
Answer:

Step-by-step explanation:
We know that the transformations of a cosine equation can be shown as:
y=±a(b(x-h))+k
Where 'a' is the amplitude
'b' is the horizontal change (Do 2π/b to find the period)
'h' is the horizontal shift
and 'k' is the vertical shift or midline.
------------------------------------------------------
If the amplitude is 4, we can assume a=4.
Since the period is 4/7, we can solve for the 'b' value by:

Next, since the midline is 2, we know that a vertical shift of 2 occurred. Thus, the 'k' value is 2.
Writing this equation gives us:

Step-by-step explanation:
Given

The question has missing details; as what's required is not stated.
However, since it is a linear equation, possible questions could be
1. Determine the slope
2. Determine the D-intercept
3. Calculate the amount in dollars for (say) 5 miles
An equation is represented as:

Where


By comparing:
to 
and 
This means that the slope is 0.3 and the d intercept is 25
To get the amount for 5 miles, we substitute 5 for x in 



<em>The cost of 5 miles is $26</em>
