Ina aeronave parte desde un aeropuerto y toma la iguiente ruta: primero vuela hacia la ciudad A, localizada 175 km en dirección \( 30.0^{\circ} \) al noreste. A continuación, uela \( 150 \mathrm{~km} 20.0^{\circ} \) al oeste del norte hacia la ciudad B . inalmente, vuela 190 km hacia el oeste hacia la ciudad unto de partida.

\[ L=0.2(t-2010)+10 \] The lifespan of a certain bird has been tracked from the year 2010 , and the average lifespan is modeled by the equation above. In 2010 the lifespan of the bird was 10 years. What is the meaning of the number 0.2 in the equation? A) The lifespan in the year 2010 B) The life span increase each year from 2010 C) The lifespan increase every 10 year D) The life span decrease each year from 2010 D)
