Final answer:

To find out how far Randy's baby is from the starting point after crawling in the described pattern, one needs to use the Pythagorean theorem. The net distances north-south and east-west are used as sides of a right triangle, and the hypotenuse represents the total distance from the start. The calculation yields a distance of 37 inches away from the starting point.

Step-by-step explanation:

The question is asking to determine the distance from the starting point after moving in a specific pattern. To solve this problem, we can use the Pythagorean theorem, which relates the lengths of the sides of a right triangle.

Randy's baby crawls 18 inches north, then 35 inches west, and 6 inches south. To find the distance from the starting point, we need to determine the resultant displacement vector by finding the net distance north-south and the net distance east-west.

The net north-south distance is 18 inches north - 6 inches south = 12 inches north. The westward distance remains 35 inches since there was no movement eastward.

By treating these as sides of a right triangle, the distance from the starting point (the hypotenuse of the triangle) can be calculated using the Pythagorean theorem:

c = √(a² + b²)

Substituting the distances, we have:

c = √(12² + 35²)

c = √(144 + 1225)

c = √(1369)

c = 37 inches.

Hence, Randy's baby is 37 inches away from where he started.
