Park rangers in yosemite estimared the number of racoons in one hiking area. the rangers tagged 15 racoons in the hiking area. the following week they captured 40 racoons. if the park rangers estimated there were 75 racoons in the area, how many of the captured racoons were tagged?

8 racoons

Step-by-step explanation:

15/75=1/5 so 1/5 of the racoons are tagged. 1/5 of 40 is 8.

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.
