Question

Find the distance between points p(8, -2) and q(-3, 4) to the nearest tenth

Answer 1

Use the formula:


`A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\|AB|=√((x_B-x_A)^2+(y_B-y_A)^2)`

We have:


`P(8;\ -2);\ Q(-3;\ 4)`

substitute


`|PQ|=√((-3-8)^2+(4-(-2))^2)=√((-11)^2+6^2)\\\\=√(121+36)=√(157)\approx12.5`
