Final answer:
To find the length of the segment with endpoints at C(-23, 15) and D(-11, 4), you can use the distance formula: d = √((x2 - x1)^2 + (y2 - y1)^2). Substituting the values, we get: d = √((-11 - (-23))^2 + (4 - 15)^2). Therefore, the length of the segment CD is approximately 16.28 units.
Step-by-step explanation:
To find the length of the segment with endpoints at C(-23, 15) and D(-11, 4), you can use the distance formula:
d = √((x2 - x1)^2 + (y2 - y1)^2)
Substituting the values, we get:
d = √((-11 - (-23))^2 + (4 - 15)^2)
d = √((12)^2 + (-11)^2)
d = √(144 + 121)
d = √265
Therefore, the length of the segment CD is approximately 16.28 units.
