Answer:
3√10 or about 9.49 units.
Step-by-step explanation:
To find the distance between any two points, we may use the distance formula given by:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Let (3, 5) be (x₁, y₁) and (12, 2) be (x₂. y₂). By substitution:
[tex]d=\sqrt{(12-3)^2+(2-5)^2[/tex]
Evaluate:
[tex]d=\sqrt{(9^2)+(-3)^2[/tex]
Square:
[tex]d=\sqrt{81+9}[/tex]
Simplify:
[tex]d=\sqrt{90}=\sqrt{9\cdot10}=\sqrt{9}\cdot\sqrt{10}=3\sqrt{10}\approx9.49[/tex]
The distance between (3, 5) an (12, 2) is 3√10 or about 9.49 units.
