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

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)

By definition of probability, the probability that a student surveyed was either a boy or had a bicycle is 62%.

Probability is the greater or lesser possibility that a certain event will occur.

In other words, the probability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.

The union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".

The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:

P(A∪B)= P(A) + P(B) -P(A∩B)

The intersection of events, A ∩ B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A ∩ B is verified when A and B occur simultaneously.

In first place, let's define the following events:

Then you know:

In this case, considering the definition of union of eventes, the probability that a student surveyed was either a boy or had a bicycle is calculated as:

P(A∪B)= P(A) + P(B) -P(A∩B)

P(A∪B)= 0.49 + 0.32 -0.19

P(A∪B)= 0.62= 62%

Then, the probability that a student surveyed was either a boy or had a bicycle is 62%.

The contract really worth today if global enterprises can earn 12 percent on its money will be 2.58 million.

The participants that sign the agreement agree to the statement's provisions as well as their commercial duties.

Global enterprises have just signed a $3 million contract.

The contract calls for a payment of $0.5 million today, $0.9 million one year from today, and $1.6 million two years from today.

Then the contract really worth today if global enterprises can earn 12 percent on its money will be

Contract really worth today = 0.5m + (0.9m/1.12) + (1.6m/1.12²)

Contract really worth today = $2.579 million

Contract really worth today ≅ 2.58 million

In the long run, diseconomies of scale will exist as the inputs are raised by 10 percent and the output by 5 percent.

Diseconomy is the disadvantage of the financial and the economical sector of the long-run businesses that arise when the input and the cost of production are increased.

The input and the output are dependent on each other and the cost of production determines the financial gain or loss in a business. So, if the input and the output both are increasing then it will lead to diseconomy.

Therefore, the 10 percent increase in input and 5 percent increase in output leads to diseconomy.

If R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.

In ring theory, a commutative ring can be defined as a ring in which the multiplication operation is considered to be commutative in nature.

Let R represent a commutative ring with characteristic K.

Therefore, we have: Kr = 0∀r ∈ R.

Assuming f(x) ∈ R(x)

Then, f(x) would be given by: [tex]a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0=0[/tex]

Also, in some instances ai ∈ R and n ∈ N.

Finally, we would have:

[tex]Kf(x) = K(a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0)\\\\Kf(x) = Ka_n x^n + Ka_{n-1} x^{n-1} +.......+ Ka_1 x^1 +Ka_0\\\\Kf(x) = 0\times x^n + 0\times x +.......+ 0[/tex]

Kf(x) = 0.

Therefore, we can infer and logically deduce that if R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.
