The table shows the numbers of cellular phone subscribers S (in millions) in the United states from 1999 through 2004, where t represents the year, with t = 9 corresponding to 1999. Use the regression feature of a graphing utility to find a linear model for the data. Use the model to find the year in which the number of subscribers exceeded 200 million.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
