The medians of ΔMNO are concurrent. Proof:StatementsReasons1. ∆MNOGiven2. Use rigid transformations to transform ΔMNO to the congruent ΔM'N'O' so that M' is at the origin and M'O' lies on the x-axis in the positive direction. Rigid transformations result in congruent shapes.3. Any property that is true for ΔM'N'O' will also be true for ΔMNO. Definition of congruence4. Let r, s, and t be real numbers such that the vertices of ΔM'N'O' are M'(0,0), N'(2r,2s), and O'(2t,0).Defining constants5. Let P', Q', and R' be the midpoints of M'N', N'O', and M'O', respectively. Defining points6. P' = (r, s); Q' = (r + t, s); R' = (t,0)?7. Definition of slope8. Applying point-slope formula9. and intersect at point S. Algebra10. Point S lies on .The coordinates of S satisfy the equation of .11. All three lines share point S. Follows from 9 and 1012. The medians are concurrent.

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

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.
