Question
sylvia enlarged a photo to make a 24 x 32 - inch poster using the dilation d_q,4. what are the dimensions, in inches, of the original photo? 3 x 8 6 x 4 12 x 16 18 x 24
Step1: Identificar el factor de dilatación
El factor de dilatación $D_Q,4$ significa que el factor de dilatación $k = 4$.
Step2: Calcular las dimensiones originales
Si $l_{poster}=24$ pulgadas y $k = 4$, entonces la longitud original $l_{original}=\frac{l_{poster}}{k}=\frac{24}{4}=6$ pulgadas. Si $h_{poster}=32$ pulgadas, entonces la altura original $h_{original}=\frac{h_{poster}}{k}=\frac{32}{4}=8$ pulgadas.
