Answer:
Number of units possible in S are 4.
Explanation:
Given S is a set of complex number of the form [tex]a+bi[/tex] where a and b are integers.
[tex]z\in S[/tex] is a unit if [tex]w\in z[/tex] exists such that [tex]zw=1[/tex].
To find:
Number of units possible = ?
Solution:
Given that:
[tex]zw = 1[/tex]
Taking modulus both sides:
[tex]|zw| = |1|[/tex]
Using the property that modulus of product of two complex numbers is equal to their individual modulus multiplied.
i.e.
[tex]|z_1z_2|=|z_1|.|z_2|[/tex]
So,
[tex]|zw| = |1|\\\Rightarrow |zw| =|z|.|w| =1\\\Rightarrow |z|=\dfrac{1}{|w|}[/tex]......... (1)
Let [tex]z=a+bi[/tex]
Then modulus of z is [tex]|z| = \sqrt{a^2+b^2}[/tex]
Given that a and b are integers, so the equation (1) can be true only when [tex]|z| = |w| =1[/tex] (Reciprocal of 1 is 1). Modulus can be equal only when one of the following is satisfied:
(a = 1, b = 0) , (a = -1, b = 0), (a = 0, b = 1) OR (a = 0, b = -1)
So, the possible complex numbers can be:
[tex]1.\ 1 + 0i = 1\\2.\ -1 + 0i = -1\\3.\ 0+ 1i = i\\4.\ 0 -1i = -i[/tex]
Hence, number of units possible in S are 4.
South Korea has developed amazingly, with huge corporations making vast amounts of money and giving everyone there a high standard of living, while the vast majority of people in the Central American nation of Guatemala are plagued by extreme poverty, violence, and poor living conditions. This is an example of:
Answer: Uneven Development
Explanation:
South Korea is one of the success stories of the last century. After the Korean War devastated large parts of the Korean peninsula, foreign aid poured in and the people embraced development fully. This led to the development of large corporations such as Samsung making vast amounts of money and giving everyone there a high standard of living.
Guatemala on the other hand has been ravaged by poverty and poor living conditions for a long time resulting from a bloody civil war that lasted for decades. This led to gangs been formed to compete for resources as well as illegal activities being carried out such as drug trafficking. This only made things worse.
These are 2 countries are a prime example of how countries in the world are experiencing Uneven Development. How in one nation the standards of living are high and people are safer but on the same planet and in another nation people are living in abject poverty and fearing constantly for their lives.

The market for plywood is characterized by the following demand and supply equations: QD = 800 – 10P and QS = 50P – 1,000, where P is the price per sheet of plywood and Q measures the quantity of plywood. What is the size of the deadweight loss if the government imposes a price ceiling of $25 per she
Answer:
$3,750
Explanation:
at $25 per sheet of plywood:
total demand = 800 - (10 x 25) = 800 - 250 = 550
total supply = (50 x 25) - 1,000 = 1,250 - 1,000 = 250
the equilibrium price is:
800 - 10P₁ = 50P₁ - 1,000
1,800 = 60P₁
P₁ = 1,800 / 60 = 30
the equilibrium quantity (Q₁) is:
Q₁ = 800 - (10 x 30) = 800 - 300 = 500
at 250 units, the price should be:
250 = 800 - 10P₂
10P₂ = 550
P₂ = $55
total deadweight loss = 0.5 x (P₂ - P₁) x (Q₂ - Q₁) = 0.5 x ($55 - $25) x (250 - 500) = 0.5 x $30 x -250 = -$3,750
