Answer:
a is the _amplitude_(Length of the blades)_
The vertical shift, k, is the _Mill shaft height_
Step-by-step explanation:
In this problem the amplitude of the sinusoidal function is given by the length of the blades.
The mill is 40 feet above the ground, therefore the function must be displaced 40 units up on the y axis. So:
We know that the blades have an angular velocity w = 3 rotations per minute.
One rotation =
1 minute = 60 sec.
So:
Finally:
a is the _amplitude_(Length of the blades)_
The vertical shift, k, is the _Mill shaft height_

Given:
The cost function
where x is the number of miles the truck has been driven.
Graph:
We must first construct the table. We start by manually calculating the valueof c(x) for every x starting with x = 0.
We may take any real values of x ≥ 0 to make our table. Here, I have chosen x = 0, 10, 20, 30, 40, 50, 60, 70.
We then plot the points of x on the x-axis and of c(x) on the y (or vertical) axis.
The graph as well as the table have been uploaded as images.
Concept & Explanation:
<u>Domain</u> - the domain of the given function is the set of all the values that x can take for the function to be valid.
<u>Range</u> - the range of the given function is the set of all the values c(x) will take for each value of x in the domain.
Here, x represents the number of miles driven and c(x) represents the cost of renting. Clearly, neither x nor c(x) can be negative. Moreover, both these values will be real numbers.
Note that x may be zero (if the renter doesn't drive the truck at all) or x may be positive.
Taking the case when x = 0,
Therefore, we have identified the lower limits of both the domain and the range.
Seeing as the moving company has not imposed an upper limit on the number of miles that can be written, we can not reasonable identify any upper bounds for the domain and range.
So, domain is the set 0 ≤ x < ∞
And, range is the set 70 ≤ c(x) < ∞
