Given:
A(5,0)
B(-2,-7)
[tex] r_{A} =3[/tex]
[tex] r_{B} =7[/tex]
[tex]Ratio: \frac{ r_{A} }{ r_{B} } = \frac{3}{7} [/tex]
req'd:
P(x,y)
Formula:
[tex] P_{x}= \frac{ A_{x} r_{B} + B_{x} r_{A} }{ r_{A} + r_{B} } [/tex]
[tex] P_{y}= \frac{ A_{y} r_{B} + B_{y} r_{A} }{ r_{A} + r_{B} } [/tex]
Solution:
[tex] P_{x}= \frac{ (5)(7) + (-2)(3) }{ 7 + 3 } [/tex]
[tex] P_{x} =2.9[/tex]
[tex] P_{y}= \frac{ (0)(7) + (-7)(3) }{ 7 + 3 } [/tex]
[tex] P_{x} =-0.7[/tex]
[tex]P(2.9,-0.7)[/tex]
