The number, , of people who have heard a rumor spread by mass media by time t is modeled by (t)=a(1−e−bt). There are 100,000 people in the population who hear the rumor eventually. If 20% of them heard it the first day, find b, assuming t is measured in days. Give your answer to three decimal places.

y/x=18

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
