Question

Find the distance CD rounded to the nearest tenth.
C=(5,6) and D (2,2)
CD=

Answer 1

Use the distance formula to find the distance between points C (5,6) and D (2,2).

d=
`√((x2-x1)^2+(y2-y1)^2)`

Plug the corresponding values in to the equation.

d=
`√((2-5)^2+(2-6)^2)`

Then simplify the rest of the equation.

d=
`√((-3)^2+(-4)^2)`

d=
`√(9+16)`

d=
`√(25)`

d=
`5`

The distance of the two points CD is 5.
