2 * 10 ^-4

Step-by-step explanation:

We need the first number to be between 1 and less than 10

.0002

2  * 10 ^ exponent

We move the decimal 4 places to the right.  Since we move it to the right the exponent is negative and is the number of places we moved the decimal

2 * 10 ^-4

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.
