Answer:

The robot's location from its initial location after 7 minutes is (233, 386)

Distance moved from initial location = 451.56 yards < 59.2° North-East

Explanation:

Since the robot moves 33 yards east and 55 yards north each minute, the distance it moves east in 7 minutes is 33 yards/minute × 7 minutes = 231 yards.

The distance it moves north in 7 minutes is 55 yards/minute × 7 minutes = 385 yards.

The robot's location from its initial location after 7 minutes is (2 + 231, 3 + 385) = (233, 388)

The distance moved from the initial location is

r = √(231² + 385²)

= √(53361 + 150544)

= √203905

= 451.56 yards

Its direction is gotten from tanθ = distance moved north/distance moved east = 388/231 = 1.680

θ = tan⁻¹(1.680) = 59.23° ≅ 59.2°
