Xét các số phức z=a+bi (a, b€ R) thỏa mãn |z -4-3i|=5. Tính a+b khi biểu thức T=3|z+2i|²+2|z-4+i|²+|z+2-2i|² đạt giá trị lớn nhất.

e) none of the above because the measure of angle cba is 101°

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.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
