Question

Find the distance cd rounded to the nearest tenth c=(5,6) d=(2,2) cd=?

Answer 1

I have the Same answer as the first person.

Answer 2

c=(5,6) d=(2,2) cd=?
distance cd = sqrt [(2-5)^2 +(2-6)^2]
distance cd = sqrt[(-3)^2 +(-4)^2]
distance cd = sqrt(9+16)
distance cd = sqrt(25)
distance cd = 5

answer
cd = 5
