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=$\sqrt{(x2-x1)^2+(y2-y1)^2}$

Plug the corresponding values in to the equation.

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

Then simplify the rest of the equation.

d=$\sqrt{(-3)^2+(-4)^2}$

d=$\sqrt{9+16}$

d=$\sqrt{25}$

d=$5$

The distance of the two points CD is 5.
