a) para calcular dónde está la imagen podemos usar esta fórmula de lente,
\frac{1}{f}=\frac{1}{v}-\frac{1}{u}
Según la nueva convención de notación cartesiana, debemos asignarle valores.
\frac{1}{-3}=\frac{1}{v}-\frac{1}{10}
v=-\frac{30}{7}=-4.28\:cm
entonces la imagen mide 4,28 cm en el lado derecho
