a rectangle has one side that is fixed at 10cm. how fast is the area of the rectangle changing at the instant when the other side is 12cm and increasing at 3cm per minute?

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.  

i think the amount would be $140.62

i believe that the answer is

b. y-1=-2(x-4)

hope this !

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.
