In a lab experiment, 510 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 20 hours. How long would it be, to
the nearest tenth of an hour, until there are 1220 bacteria present?
what’s the answer

yrahh maybe it can be a bit if its not a its b

3 is greater then both of those numbers

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
