Nicole is really getting tired of the loud group behind her in BioCalculus class, so she decides to spread a rumor about them to her closest friends. Nicole is very popular and has many friends. The number of friends of Nicole, N(t) , who have heard the rumor by time t in hours since the rumor started to spread can be approximated by a function of the form N(t ) = L 1 + Ce-ki If you are given the following values for the variables of the function L = 169 C = L - 1 (that is whatever your value of L equal take minus 1 for the value of C) k = 0.11 How many people knew the content of the rumor when it began spreading?
