Aweb developer uses the equation y=110x+20, where x is the number of cents spent on advertising, to estimate the number of visitors a website receives in 1 day.

how many visitors should the web developer expect in a week (7 days) if he spends 5 dollars a day on ads?

385,140

Step-by-step explanation:

The number for one day is predicted to be 110·500+20 = 55020, so the number for 7 days is expected to be 7 times that value.

7·55020 = 385,140

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
