A circle has a radius of
37 units and is centered at (1.3, -3,5). What is the equation of the circle?

If the radius is 37 units, the equation of the circle is

x² + y² - 2.6x + 7y - 1355.06  = 0

If the units is actually 3.7 units, then the equation becomes

x² + y² - 2.6x + 7y + 0.25 =0

Step-by-step explanation:

The general equation of a circle is given as

(x - a)² + (y-b)² = r²

where a and are the center of the circle along the x and y axis respectively.

Hence a circle that has a radius of  37 units and is centered at (1.3, -3,5) may be given as

(x - 1.3)² + (y + 3.5)² = 37²

x² - 2.6x + 1.69 + y² + 7y + 12.25 = 1369

x² + y² - 2.6x + 7y - 1355.06  = 0

If the units is actually 3.7 units,

x² + y² - 2.6x + 7y + 0.25 =0

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.
