If vector u=(5,-7) and v=(-11,3), 2v-6u= and ||2v-6u||≈

In this problem we have two vectors:

So we need to find two things:

and:

FIRST:

In this case we have the multiplication of vectors by scalars. A scalar is a simple number, so:

SECOND:

If we name:

Then, is the magnitude of the vector . Therefore:

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.
