Answer:
5.4 units
Step-by-step explanation:
1) Using the given distance formula of [tex]d = \sqrt{(x_2-x_1)^2+(y_2-x_1)^2}[/tex], find the distance between the pair of points. Substitute the x and y values of the points (8,4) and (3,2) into the formula and simplify:
[tex]d = \sqrt{(8-3)^2+(4-2)^2}\\d = \sqrt{(5)^2+(2)^2} \\d = \sqrt{25+4} \\d = \sqrt{29}[/tex]
So, the distance is [tex]\sqrt{29}[/tex] units. Put that value into the calculator and round the result to the nearest tenth, or the first place to the right of the decimal point. The distance is 5.4 units.
