There is initially 500 bacterial in a population in a dish. The bacterial are growing at a rate of 0.05; Such that () = 0^.
How many hours till the bacterial reaches a population of 15000

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb
