Answer: The value of y=9.
Answer:
18.71
Step-by-step explanation:
Answer:

Step-by-step explanation:
Let the x-axis be the time (in years) and the y-axis the value of the fax machine (in dollars).
We know that the initial value of the fax machine is $100; in other words, when the time is zero years, the value is $100, or as an ordered pair (0, 100). We also know that after 1 year the value decreases to $80, so (1, 80).
Now we can find the slope of the line passing through those two points using the slope formula

where
is the slope
are the coordinates of the first point
are the coordinates of the second point
Replacing values:


Now, to complete our model we are using the point slope formula

where
is the slope
are the coordinates of the first point
Replacing values:




We can conclude that the correct linear depreciation model is 
Your question does not make sense unless you can estimate but the answer would be 20.625
Work:
You have to multiply 5.50 to 3.75 because 45 is 75 percent of 60
The pitch of the roof is given by the ratio of the rise to the run of the roof, which is the slope of the rafter

Please find attached the simple <u>diagram of the house</u> with all measurements labeled
The reason the above value for the pitch and the diagram are correct are as follows:
The given parameters are;
Width of the section of the house on which the gable of the roof is to be placed = 50 feet
Length of the over hang on the sides of the roof = 1 foot each
Total span of the roof = 52 feet
Horizontal length of each rafter, the run = 26 feet
The height of the ridge above the top of the frame, the rise = 12 feet
Required:
- To find the pitch of the roof
- To draw a diagram of the house showing measurements
Solution:

Please find attached the <u>diagram</u> of the house showing the measurements for the roof parameters and the section of the house where the gable roof is to be placed
