Question

What is 2/3 of the distance between the points U (-1,4) and B (8,5)

Answer 1

6.037

Explanation:

`d=√((x_2-x_1)^2+(y_2-y_1)^2)\\\\U (-1,4)\quad\implies\quad x_1=-1\,,\ \ y_1=4 \\\\B (8,5)\quad\implies\quad x_2=8\,,\ \ y_2=5\\\\\frac12d=\frac23√((8+1)^2+(5-4)^2)=\frac23√(81+1)=\frac23√(82)\approx6.037`
