Consider the complex number z = a + bi that represents a point in the complex plane. The modulus of this number, denoted by |z|, is the distance from the point that z represents to the origin of the complex plane. Knowing that a complex number z1 has a real part of 3 and an imaginary part of 4, and that a complex number z2 has a real part of -2 and an imaginary part of 2, calculate the modulus of the complex number resulting from the sum z1 + z2.
a.
√39
b.
√35
c.
√37.
d.
√36
e.
√34

In a class about complex numbers, the teacher states that all numbers can be represented in the form of a complex number. He challenges his students to find out what is the imaginary part of a complex number formed by 5 - the real part, with the representation of the complex number in the form a + bi. What is the imaginary part of this complex number?

A martial arts school is holding a competition and decides to use complex numbers to represent the coordinates of the points where the participants are located on a mat. A competitor is at the position (3 + 7i), and the organizer wants to know what is the conjugate of this position for further analysis. What is the conjugate of the point where the competitor is?

A car is traveling at a speed of 80km/h when it crosses a section of 1200 meters in length. Knowing that from the beginning of this section the driver brakes abruptly until the car stops, determine the time required for the complete stop. Consider that the car's deceleration is constant and -5m/s². (The problem must be solved by forming a quadratic equation, finding the roots, and interpreting which one is the correct answer for the stopping time).
