The number of people in a town of 10,000 who have heard a rumor started by a small group of people is given by the following function: N(t)=10,000/5+1245e^-.97t a. How many people were in the group that started the rumor? b. How many people have heard the rumor after 1 day? After 5 days? c. How long will it be until 1,000 of the people in the town have heard the rumor?
@satellite73 could you possibly help me with this one as well?
i should make a template for this, because it is maybe the 8th time i have seen this exact same question they really stretch for these word problems, don't they ? what book does it come from ?
they do, i'm not sure its from a test study guide
i will help, but i am almost certain you can do this first one replace \(t\) by \(0\) and get \[\frac{10,000}{5+1245}\]
second one, find \(N(1)\) and \(N(5)\) by replacing \(t\) by \(1\) and \(5\) respectively, use a calculator
so the answer to a is 8?
only the third one requires real work
yeah, 8
thanks
what would i do for b?
replace \(t\) by \(1\)
then replace \(t\) by \(5\) you need a calculator
in what equation?
@satellite73
is this correct? 2009.7463 @satellite73
