What is the length of segment CD question mark
mars1129 [50]

Answer:

CD = two square root of 10 end square root

Step-by-step explanation:

To find the length of a segment, use the distance formula. Substitute the order pairs for the endpoints of the segment. CD has the end points (-7, -4) and (-1, -2).

d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2} \\\\d = \sqrt{(-4--2)^2 + (-7--1)^2} \\\\d = \sqrt{-2^2 + -6^2}\\\\d = \sqrt{4 + 36}\\\\d=\sqrt {40} = 2\sqrt{10}

Find the distance between (6, -7), (3, -5) round your answer to the nearest tenth
saw5 [17]

Answer:

d ≈ 3.6 units

Step-by-step explanation:

calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (6, - 7 ) and (x₂, y₂ ) = (3, - 5 )

d = \sqrt{(3-6)^2+(-5-(-7))^2}

   = \sqrt{(-3)^2+(-5+7)^2}

   = \sqrt{9+2^2}

   = \sqrt{9+4}

    = \sqrt{13}

    ≈ 3.6 ( to the nearest tenth )
