interval [0, 27).
COS X - 1 = -COS X
<= U

X = π/3, 5π/3

I think thats the answer

Step-by-step explanation:

hope i helped

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.
