This would be a mentor-D. They role is to mentor or guide you with advice or assistance. A role model is a similar answer in that they respect you, but they might not offer advice or assistance which makes it incorrect.
English:
Recycling, in general, is good, it saves space in landfills and prevents pollution. Because some of the materials used to make the electronic piece are made with toxic ingredients its better to recycle them instead of having them end up in our oceans. Also, some pieces of electronics contain valuable metals like gold and copper. These Metals can be reused to make new better electronics with having to use the energy and money to produce new materials

El reciclaje, en general, es bueno, ahorra espacio en los vertederos y evita la contaminación. Debido a que algunos de los materiales utilizados para fabricar la pieza electrónica están hechos con ingredientes tóxicos, es mejor reciclarlos en lugar de que terminen en nuestros océanos. Además, algunos componentes electrónicos contienen metales valiosos como el oro y el cobre. Estos metales se pueden reutilizar para fabricar nuevos y mejores productos electrónicos con la necesidad de utilizar la energía y el dinero para producir nuevos materiales.
Answer:
Solution: In this case, the system can be modeled as a function with two output signals,

where

where(x(t), y(t)) is the position of the tail in they plane. This model Is Clearly not linear. If the Input torque doubles, for example, the output values will not double. In fact, the output values are constrained to lie on a circle centered at the origin, regardless of the Input. For this reason, the model is BIBO stable. The output is always bounded. Thus, while our previous model was linear and unstable, this one Is nonlinear and stable. Which model is more useful?
