37) Website popularity ratings are often determined using models that incorporate the number of visits per week a website receives. One model for ranking websites is P(x)= log(x– 4), where x is the number of visits per week in thousands and P(x) is the website's popularity rating. According to this model, if a website is visited 16,000 times in one week, what is its popularity rating, rounded to the nearest tenth? Graph y= P(x) on the axes below. y 4 4 6 8 10 12 14 16 18 20 Site Visits (in thousands) An alternative rating model is represented by R(x) =x-6, where x is the number of visits per week in thousands. Graph R(x) on the same set of axes. For what number of weekly visits will the two models provide the same rating? 2. 2. Popularity Rating

Transcribed Image Text:37) Website popularity ratings are often determined using models that incorporate the number
of visits per week a website receives. One model for ranking websites is P(x)=log(x-4),
where x is the number of visits per week in thousands and P(x) is the website's popularity
rating.
According to this model, if a website is visited 16,000 times in one week, what is its popularity
rating, rounded to the nearest tenth?
Graph y = P(x) on the axes below.

An alternative rating model is represented by R(x)=-x-6, where x is the number of visits per
week in thousands. Graph R(x) on the same set of axes. For what number of weekly visits will
the two models provide the same rating?
