Question

Given the points A ( -2 , 1 ) and B ( 3 , -10 )
What is the length of the segment AB?

Answer 1

length of segment AB = 146)^1/2

Answer 2

Answer: (146)^1/2

Explanation:

|B-A|=

|(3, -10)-(-2, 1)|=

|(3-(-2), -10-1)|=

|(3+2, -11)|=

|(5, -11)|=(5, 11)

Distance Formula: a^2+b^2=c^2

5^2+11^2=c^2

25+121=c^2

c^2=146

c=(146)^1/2 ==> length of segment AB
