To find the distance between the mother and the baby we have to calculate the distance in x and the distance in y so:
[tex]\begin{gathered} x=7-(-7)=14 \\ y=7-2=5 \end{gathered}[/tex]Now we can use the pythagorical theorem to find the distance so:
[tex]\begin{gathered} d=\sqrt[]{5^2+14^2} \\ d=\sqrt[]{25+196} \\ d=\sqrt[]{221} \\ d=14.866 \end{gathered}[/tex]
