Find the center and radius of the circle whose equation is x2 + y2 - 6x-2y+ 4 = 0
(3,1), r = 16
(-3,-1), r= V6
(3.1) r= 6
(9,1), r= 36

its definatley   this on your answer choice?

answer: the value of x is 7cm

step-by-step explanation:

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

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.
