QUESTION 3 5 points Save 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? Round to the nearest person. QUESTION 4 20 points Save Ans 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 (number given in previous problem) 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 kt Based on the values you were given in the previous question, when is the rumor spreading the fastest (in hours rounded to two decimal places) and how many people heard the rumor at this time
