Find the critical points of the given function and then determine whether they are local maxima, local minima, or saddle points. f(x, y) = x2 + y2 + 2xy the critical points are on the line ; they

y/x=18

step-by-step explanation:

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.  

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
