When a news story breaks, it can generate a lot of interest, but it does not take long before another story diverts that interest. At right is a graph depicting the number of daily views for a news story about Syria and the United Nations. Homework Help ✎
Write an equation to model the situation.
If this model is typical of how interest declines for a news story, what is the half-life of interest in the story?
Write an equation that models this phenomenon for any initial value of views (I).
This is exponential decay. Write an equation of the form y = a·bx.
Since there are 3600 initial views, determine how long until there are 1800 views.
See the hint in part (a). Then let a = I.
