Answer

The total displacement vector is \( \left( 5 + \frac{3\sqrt{2}}{2}, -\frac{9\sqrt{2}}{2} - 3 \right) \) and the distance to walk straight home is calculated using the Pythagorean theorem.

The Deep Dive

Walking can be an enlightening journey, not just for the body but also for understanding vectors. When the person walks east, southeast, south, and southwest, each leg of the journey can be represented as a vector. For instance, the southeast direction means walking at a 45-degree angle, so you can break that into its x (east-west) and y (north-south) components. Fun fact: mastering vector decomposition gives you powerful tools to visualize and compute not just walking paths but even flight routes! Now, let's talk about the total displacement. When you add the components together, you can determine how far and in which direction the person would need to walk to return home. Displacement is like the straight line connecting the start and end points, ignoring all the twists and turns along the way. Calculating this is a blast—think of it as plotting a dynamic treasure map that leads you home!
