The complete question is in the attached file. So we have to choose between two graphs. On of them is a linear model while the other is an exponential model. From the statements, we have a relationship between time and the number of teams registered. So we can establishes variables in the following form:
We also know that each week 6 teams register to participate, so:
As you can see, as x increases one week, y increases at a constant ratio of 6. Therefore, this can be modeled by a linear function given by the form:
In conclusion, <em>the linear model (first graph below) is the one that bests represents the relationship between time and the number of teams registered.</em>
The length of the sticky notes is .
Further explanation:
Given:
The length of sticky notes is measured as 77 millimeters.
Calculation:
Since 1 meter contains 1000 mm, it can be written as follows:
Now, substitute 77 for x in above expression to obtain the length of sticky notes in meter as follows:
Thus, the length of the sticky notes is .
