leaving the freeway, denise slows from 55 mph to 35 mph in 4 seconds. what was her rate of deceleration?

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

5x+10 is the correct one

hope this

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.
