Answer 1

Explicação passo-a-passo:

$$\begin{lgathered}\mathsf{(x_C-x_A)^2=(1-4)^2=(-3)^2=9}\\\mathsf{(y_C-y_A)^2=(9-5)^2=4^2=16}\end{lgathered}$$

$$\begin{lgathered}\mathsf{d_{A,C}=\sqrt{(x_C-x_A)^2+(y_C-y_A)^2}}\\\mathsf{d_{A,C}=\sqrt{9+16}}\\\mathsf{d_{A,C}=\sqrt{25}}\\\huge\boxed{\boxed{\boxed{\boxed{\mathsf{d_{A,C}=5~u\cd
