Question

Use the distance formula to find the distance, to the nearest tenth, from S(5,-4) to W(-3,7)

Answer 1

Distance (d) =13.6

Explanation:

`d=√(\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2)\\\\(5,-4)=(x_1,y_1)\\(-3,7)=(x_2,y_2)\\\\d=√(\left(-3-5\right)^2+\left(7-\left(-4\right)\right)^2)\\\\d=√((-3-5)^2+(7+4)^2)\\\\d=√((-8)^2+(11)^2)\\\\d=√(64+121)\\\\d=√(185) \\\\d = 13.60147\dots \\\\\\d =13.6`
