Convert the following complex number into its polar representation -4i
maks197457 [2]

The expression which represent the polar form of complex number -4i when converted into the polar form is 4(cos π+ isin π)

<h3>What is complex number?</h3>

A complex number is the combination of real and imaginary number. In a complex number, real part and imaginary part of number is written together. For example,

a+bi

Here, (a) is the real part while (b) is the imaginary part.

The complex number which need to convert into its polar representation is,

n=-4i

It can be rewritten as,

n=0-4i

The radius r of the polar form is,

r²=0²+(-4)²

r²=0+16

r=4

The value of cos theta is,

tan θ=0/-4

θ=tan⁻¹(0)

θ=π

Thus, the polar form is,

z=rcos θ+(r sin θ)i

z=-4(cos π+ isin π)

Thus, the expression which represent the polar form of complex number -4i when converted into the polar form is 4(cos π+ isin π)

Question 1: What are three physical changes that happen to teen brains that make it difficult for someone like Gary to weigh ri
vovikov84 [41]

The three physical changes that happen to teen brains that make it difficult for someone like Gary to weigh risk and reward include:

  1. Remodeling of the brain
  2. Peak sensitivity to the neurotransmitter dopamine
  3. Influence of the steroidal hormones

<h3>What three physical changes occur in teen brains affect their ability to weigh risk and reward?</h3>

The brain is the most complex organ in the body which controls the functions of other bodily systems, organs, and processes such as thought, emotion, vision, breathing, movement, hunger and every other regulatory functions in the body.

During the teen years, the brain undergoes remarkable physical changes which affect the thought processes of the teenager in weighing risk and reward, such that the teen seeks more reward over risks.

These changes include:

  1. Remodeling of the brain in a back-to-front manner such the teen relies more on the back part of the brain, the amygdala, which is associated with strong emotions, aggression, and impulsive behavior for decision-making rather than the prefrontal cortex, which is associated with rational decision-making.
  2. Peak sensitivity to the neurotransmitter dopamine, which is linked to the reward system of the brain.
  3. Influence of the steroidal hormones produced during puberty.

In conclusion, a teenager like Gary will find it difficult to make rational decisions always because of these changes that occur in the brain during the teen years.
