Plants and algae use sunlight to make food. They do this with the process of photosynthesis, and they create excess oxygen as a waste product. The oxygen is vital for other living organisms to survive and perform their daily functions.

They use the sun to make food (glucose) and the by product of oxygen. They are then used by other animals to live.

Let $S$ be the set of complex numbers of the form $a + bi,$ where $a$ and $b$ are integers. We say that $z \in S$ is a unit if t

lakkis [162]

Answer:

Number of units possible in S are 4.

Explanation:

Given S is a set of complex number of the form $a+bi$ where a and b are integers.

$z\in S$ is a unit if $w\in z$ exists such that $zw=1$ .

To find:

Number of units possible = ?

Solution:

Given that:

$zw = 1$

Taking modulus both sides:

$|zw| = |1|$

Using the property that modulus of product of two complex numbers is equal to their individual modulus multiplied.

i.e.

$|z_1z_2|=|z_1|.|z_2|$

So,

$|zw| = |1|\\\Rightarrow |zw| =|z|.|w| =1\\\Rightarrow |z|=\dfrac{1}{|w|}$ ......... (1)

Let $z=a+bi$

Then modulus of z is $|z| = \sqrt{a^2+b^2}$

Given that a and b are integers, so the equation (1) can be true only when $|z| = |w| =1$ (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:

$1.\ 1 + 0i = 1\\2.\ -1 + 0i = -1\\3.\ 0+ 1i = i\\4.\ 0 -1i = -i$

Hence, number of units possible in S are 4.

Economic efficiency is

Marina CMI [18]

Answer:

The correct answer is option A.

Explanation:

A market outcome will be considered economically efficient if the marginal benefit earned from the last unit is equal to the marginal cost incurred in the production of the last unit while the economic surplus or the sum of consumer surplus and producer surplus is at maximum.

If the marginal cost and benefit are not equal then the outcome is said to inefficient. It means that either the resources are not being allocated efficiently or the production is not efficient.

05) Assume that prices and wages adjust rapidly so that the markets for labor, goods, and assets are always in equilibrium. What

Kay [80]

Answer:

Explanation:

a. A temporary increase in government purchases would result in a reduction in savings, which would, in turn, lead to the implementation of higher taxes by the government so as to match prices and wages.

This would: make output to remain unchanged, real interest to increase and current price level to increase as well.

b. A reduction in expected inflation would lead to an increment in the demand for real money, as people do not expect inflation to increase for a while. Thus, more demand creates a reduction in the price level. Everything else remains unchanged. This would: make output remain unchanged, real interest remain unchanged and the current price level to decrease.

C. A temporary increase in labor supply would make more people have jobs and therefore more people can save. If more people save the interest rates are liable to decrease therefore money demand will increase. This would: make output to increase, real interest to decline and current price level to decrease.

d. An increase in the interest rate paid on money will lead to a higher demand for money. With an unchanged nominal money supply and higher money demand, the price would decline but everything remains unchanged. This would make: output remain unchanged, real interest remains unchanged and the current price level decrease.
