MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A cell site is a site where electronic communications equipment is placed in a cellular network for the use of mobile phones. The numbers y of cell sites from 1985 through 2018 can be modeled by 336,011 Y= 1 + 293e-0.236t where t represents the year, with t = 5 corresponding to 1985. + (a) Use the model to find the numbers of cell sites in the years 1998, 2008, and 2015. (Round your answers to the nearest whole number.) 1998 2008 2015 V = (b) Use a graphing utility to graph the function. Use the graph to determine the year in which the number of cell sites reached 280,000. The number of cell sites reached 280,000 in (c) Confirm your answer to part (b) algebraically.
