Question

100 points number 18 pls ASAP

Answer 1

• 44 yards

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 =
  `√(9^2+12^2)=√(81+144) =√(225) =15` yds
• Ball2 ⇒ Ball3 =
  `√(12^2+16^2)=√(144+256) =√(400) =20` yds

Total distance is:

• 9 + 15 + 20 = 44 yds
