A man in a tower spots three hot air balloons flying at the same altitude. Balloon A is 5 miles east and 8 miles south of the tower. Balloon B is 7 miles west and 10 miles north of the tower. If Balloon C is located four-ninths the distance from Balloon A to Balloon B, find the location of Balloon C relative to the tower.

a) 2 miles east and 2 miles north
b) 3 miles west and 4 miles south
c) 4 miles east and 6 miles north

Final answer:

The location of Balloon C relative to the tower is approximately 2 miles east and 2 miles north. The correct answer is option a).

Step-by-step explanation:

To find the location of Balloon C relative to the tower, we first need to find the coordinates of Balloon A and Balloon B.

Given that Balloon A is 5 miles east and 8 miles south of the tower, its coordinates are (5, -8). Balloon B is 7 miles west and 10 miles north of the tower, so its coordinates are (-7, 10).

Next, we can find the distance between Balloon A and Balloon B:

Distance = sqrt((5 - (-7))^2 + (-8 - 10)^2)

= sqrt(144 + 324)

= sqrt(468)

= 6sqrt(13) miles.

Since Balloon C is located four-ninths the distance from Balloon A to Balloon B, the distance between Balloon A and Balloon C is

(4/9)(6sqrt(13))

= 8/3sqrt(13) miles.

To find the coordinates of Balloon C, we can use similar triangles. The vertical distance between Balloon A and Balloon C is 8/9 times the vertical distance between Balloon A and Balloon B, which is -8/3 miles. Similarly, the horizontal distance between Balloon A and Balloon C is 8/9 times the horizontal distance between Balloon A and Balloon B, which is -36/9 miles.

Therefore, the location of Balloon C relative to the tower is approximately 2 miles east and 2 miles north.
