10. Ross and his family like to visit a pizza restaurant that also has games.

2+2 +3+ + 7 tickets playing games. After
examining all the prizes he decided to
save for a prize with a price of
3t2 - 8t - 2 tickets. How many more
tickets does Ross need to earn on their
next visit to be able to buy the prize?

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.
