In an experiment, 20 g soil sample has been taken from the field and taken to the lab. A. From this 20 g, 10 g is air dried, grinded and sieved. It is then mixed with 20 mL distilled water to prepare 1:1 soil-water suspension, and pH of suspension is recorded which was 7.8. B. The rest 10 g soil is dried at 105 ᴼC, cool, oven dry soil weight was 8g and Bulk Density was recorded to be 2.5 g cm-3.

the answers c

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.

answer: 0.26
