write the coordinates of the vertices after a dilation with a scale factor of 3, centered at the origin.

write the coordinates of the vertices after a dilation with a scale factor of 3, centered at the origin.

Answer

Explanation:

Step1: Identificar coordenadas originales

$R(-1,-1)$, $S(-1,1)$, $T(0,3)$, $U(1,1)$

Step2: Aplicar fórmula de dilatación

Para una dilatación centrada en el origen con factor de escala $k = 3$, la fórmula es $(x,y)\to(kx,ky)$. Para $R(-1,-1)$: $R'=(3\times(-1),3\times(-1))=(-3,-3)$ Para $S(-1,1)$: $S'=(3\times(-1),3\times1)=(-3,3)$ Para $T(0,3)$: $T'=(3\times0,3\times3)=(0,9)$ Para $U(1,1)$: $U'=(3\times1,3\times1)=(3,3)$

Answer:

$R'(-3,-3)$ $S'(-3,3)$ $T'(0,9)$ $U'(3,3)$
