a.
To complete the given table.
a.

Explanation of Solution
Table:
Number of songs downloaded | Total cost($) | Total Cost/Number of Songs Downloaded |
2 | 4 | 2 |
4 | 8 | 2 |
6 | 12 | 2 |
Conclusion:
Hence the above table has been completed according to data.
b.
To explain how the cost changes with the number of increase of the songs downloaded.
b.

Explanation of Solution
Given:
Number of songs downloaded | Total cost($) | Total Cost/Number of Songs Downloaded |
2 | 4 | 2 |
4 | 8 | 2 |
6 | 12 | 2 |
Interpretation:
When the table is observed, it is clear that, when there is a increase in Number of songs downloaded, the total cost also increases.
Which means, if there is ‘ n’ times increment in the number of songs downloaded, there will be ‘ n’ times increment in the Total Cost.
Conclusion:
The above interpretation makes it clear that the Number of songs downloaded and Total Cost bear a linear relationship.
c.
To interpret the value of Total Cost divided by Number of songs downloaded.
c.

Explanation of Solution
Given:
Number of songs downloaded | Total cost($) | Total Cost/Number of Songs Downloaded |
2 | 4 | 2 |
4 | 8 | 2 |
6 | 12 | 2 |
Interpretation:
Here, When the table is observed, the value of total cost divided by total number of songs downloaded
is constant and equal to 2. This means, numerically the value of total cost will be twice the value
of number of songs downloaded.

- Patterns in Floor Tiling A square floor is to be tiled with square tiles as shown. There are blue tiles on the main diagonals and red tiles everywhere else. In all cases, both blue and red tiles must be used. and the two diagonals must have a common blue tile at the center of the floor. If 81 blue tiles will be used, how many red tiles will be needed?arrow_forwardFind the values of n, if the points (n + 1, 2n), (3n, 2n + 3) and (5n + 1,5n) are collinear.

The water heater is shut off and the water cools to the temperature of the surrounding air, which is 60°F. The water cools slowly because of the insulation inside the heater, and the value of k is measured as 0.00351. a. Write a function that models the temperature T (t) (in °F) of the water t hours after the water heater is shut off. b. What is the temperature of the water 12 hr after the heater is shut off? Round to the nearest degree. c. Dominic does not like to shower with water less than 115°F. If Dominic waits 24 hr. will the water still be warm enough for a shower?
