Complex Numbers: Gauss Plane

Medium

(Originais Teachy 2023) - Question Medium of Mathematics

In an imaginary city, each point on the map is represented by a complex number in the Gauss Plane. The city hall is located at the coordinate point z = 3 + 4i and the nearest hospital is at the point w = 1 - 2i. The mayor of the city, who was at the city hall, needs to go to the hospital. Considering that each unit on the map corresponds to 1 km in the city, what is the minimum distance the mayor needs to travel to reach the hospital? Additionally, in which quadrant of the Gauss Plane is the hospital located?
a.
The minimum distance the mayor needs to travel to reach the hospital is 4√10 km and the hospital is located in the fourth quadrant of the Gauss Plane.
b.
The minimum distance the mayor needs to travel to reach the hospital is 2√10 km and the hospital is located in the second quadrant of the Gauss Plane.
c.
The minimum distance the mayor needs to travel to reach the hospital is 2√10 km and the hospital is located in the first quadrant of the Gauss Plane.
d.
The minimum distance the mayor needs to travel to reach the hospital is 2√10 km and the hospital is located in the third quadrant of the Gauss Plane.
e.
The minimum distance the mayor needs to travel to reach the hospital is 2√10 km and the hospital is located in the fourth quadrant of the Gauss Plane.

In a renovation, an architect decides to completely cover a right prism with a square base with ceramic tiles that are in the shape of squares. The prism is 3 meters high and the edge of the base measures 2 meters. The tiles are 20 cm on each side. The architect will need to calculate the amount of tiles to cover the entire surface of the prism. How many tiles will be needed to completely cover the prism?

During the cleaning of the cooling system of a factory, a technician must adjust a light reflector fixed on the ceiling of the room. The reflector has the shape of a right circular cone with the vertex pointing upwards and an opening angle of 75º. The technician wants to calculate the height and the radius of the base of the cone to determine the ideal dimensions of the mirrors that will be installed on the inner surface of the cone, so that the reflected light follows a beam parallel to the floor. Consider that the angle of incidence of light on the inner surface of the cone should be 15º with the normal to the surface at the point of incidence to ensure total reflection of light. Based on this configuration, determine the height and the radius of the base of the cone, and additionally, identify the value of the sine and cosine of 22.5º, an angle that arises in the resolution of the problem.
