Answer:
Step-by-step explanation:
Possible roots from point F to Ball 3 are:
- F ⇒ Ball2 ⇒ F ⇒ Ball1 ⇒ Ball3
- F ⇒ Ball2 ⇒ Ball1 ⇒ Ball3
- F ⇒ Ball1 ⇒ Ball2 ⇒ Ball3
Its not difficult to see the shortest root the the last one.
Let's find each part of the total distance:
- F ⇒ Ball1 = 9 yds
- Ball1 ⇒ Ball2 = [tex]\sqrt{9^2+12^2}=\sqrt{81+144} =\sqrt{225} =15[/tex] yds
- Ball2 ⇒ Ball3 = [tex]\sqrt{12^2+16^2}=\sqrt{144+256} =\sqrt{400} =20[/tex] yds
Total distance is:
