In this part, you will use data about Myspace usage to createmodels for the decay in the use of that site, as measuredby millions of unique visitors per month. Youevaluate those models for how well they predict usage at particulartimes, as well as time to reach particular usage levels.
C. In January 2014, Myspace had 49.7million unique visitors from the U.S. In January 2015, there were32.2 million unique Myspace visitors from the U.S
1.Create an explicit exponential formula relating thenumber of months after January 2014 (m)and the number of unique Myspace visitors from the U.S. inthatmonth (Um) Um=
Note: Remember to round as little as possible; you will need tokeep at least5 decimal places.
2. Based on your exponential model in #18, what was thenumber of unique U.S. visitors to Myspace in July 2015? (blank)millions of U.S. visitors per month
3. Based on your exponential model in #18, what was thenumber of unique U.S. visitors to Myspace in July2013? (blank) millions of U.S. visitors per month
4. Based on your exponential model in #18, when did/willthe number of unique U.S. visitors to Myspace be 1 million? (Give the month and year it will occur during. For example, if itwould happen this month, enter "July 2022"; if the result won'tever happen, enter "never".)
5. Based on your exponential model in #18, when did/will thenumber of unique U.S. visitors to Myspace reach zero? (Give themonth and year it will occur during. For example, if it wouldhappen this month, enter "July 2022"; if the result won't everhappen, enter "never".)
6. Do you think this exponential model could be a goodmodel for the decline in number of unique U.S. visitors toMyspace? Why, or why not?
7. Now create an explicit linear formularelating the number of months after January2014 (m) and the number of uniqueMyspace visitors from the U.S. in thatmonth (Um). Um=
Note: Remember to round as little as possible; you will need tokeep at least5 decimal places.
8. Based on your linear model in #24, what was the numberof unique U.S. visitors to Myspace in July 2015? (blank)millions of U.S. visitors per month
9. Based on your linear model in #24, what was the numberof unique U.S. visitors to Myspace in July 2013? (blank)millions of U.S. visitors per month
10. Based on your linear model in #24, when did/will thenumber of unique U.S. visitors to Myspace be 1 million? (Givethe month and year it will occur during. For example, if it wouldhappen this month, enter "July 2022"; if the result won't everhappen, enter "never".)
11. Based on your linear model in #24, when did/will thenumber of unique U.S. visitors to Myspace reach zero? (Givethe month and year it will occur during. For example, if it wouldhappen this month, enter "July 2022"; if the result won't everhappen, enter "never".)
12. Do you think this linear model could be a good modelfor the decline in number of unique U.S. visitors to Myspace? Why, or why not?
13. In reality, the average number of unique U.S. visitorsto Myspace in July 2015 was 17.9 million, in July 2013 was 18.6million, and the number has not yet dropped to one million orless. Considering this additional data, do you think eitherof your models is a good model for the decline in number of uniqueU.S. visitors to Myspace? Why, or why not?
