A) The cost to send a package that weighs 3.2 pounds is $4.13. Since this weight exceeds 3 pounds but remains below 4 pounds, we have to refer to the pricing that applies to 4-pound packages (see the attached document for pricing details).
b) To illustrate the Media Mail shipping costs based on the weight of the books, a line graph is appropriate. In this graph, the weight in pounds is represented on the x-axis and the shipping costs on the y-axis.
c) The graph depicting the Media Mail shipping costs as a function of book weight will be represented by the equation: f(x) = 2.69 + 0.48(x-1)
Answer:
To summarize the answer:
Step-by-step explanation:
Given:

Here is the graph associated with this question:
The second function, denoted as
, does not qualify as a function.
Keep in mind that the g(x) function is the inversion of the f(x) function. Recognizing this pattern indicates a reflection on the Y-axis.
Reflection on the axes:
In the x-axis:
Enhance the function by -1 to illustrate an exponential curve around the x-axis.
In the y-axis:
Decrease the input of the function by -1 to depict the exponential function around the y-axis.
Answer:

Explanation step-by-step:
Let
x represent Hermione's salary prior to the raise
Given:

Therefore, the equation that expresses this relationship is

To find x, divide both sides by 1.05:


Answer:
Begin by selecting two points from the data. Determine the difference between the second y-coordinate and the first y-coordinate. Next, take that difference divided by the difference between the second x-coordinate and the first x-coordinate.
