3.) A rocket carrying fireworks is launched from a hill 80 feet above a lake. The
rocket will fall into the lake after exploding at its maximum height. The
rocket's height above the surface of the lake is represented by
h=- 16t2 +64t + 80. How many seconds after the rocket launched will it
hit the lake?

step-by-step explanation:

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.
