Below is the proof that the sum of two odd numbers is always even.

First, remember that an even number is written as:

x = 2*n

Where n is an integer number.

While an odd number will be written as:

y = 2*n + 1

Now, let's say that we have two odd numbers:

A = 2k + 1

B = 2n + 1

If we add these we get:

A + B = (2k + 1) + (2n + 1) = 2k + 2n + 2 = 2*(k + n + 1)

And k + n + 1 is an integer number, then we can write:

k + n + 1 = N

So we get:

A + B = 2N

Then the sum of A and B is an even number.

Thus, we proved that for the sum of any two odd numbers, the outcome will always be even.

The function of the female reproductive system is to promote fertilization and serve as a container for the new individual until the end of its gestation.

It is in charge of physically and biochemically promoting the encounter between the sperm and the ovules generated by a female.

This union occurs in the uterus and, once the cells have been fertilized, a zygote is generated which, after nine months of growth, will become a new human individual.

Therefore, we can conclude that the female reproductive system differs from other body systems since it allows the fertilization of the ovum, pregnancy and the birth of a new individual.

We are told that;

Number of new cars Nico surveyed = 300

Percentage of buyers that surveyed the new cars = 75% .

Thus, number of customers surveying this cars = 75% * 300 = 225 customers

If people are satisfied with their car's current company and brand and model,it means that they can also prefer the same thing again for the same better experience. Thus, the conclusion is that;

Step-by-step explanation:

The main interaction between the urinary system and the circulatory system is both of the following parts of the human body work for the kidney.

The human body is the collection of many systems like the cardiovascular system for the heart, the urinary system for filtering the body, the circulating system for movement, and so on. All these functions help the body to regulate the smooth functioning of the body.

When the blood enters the kidney through arteries they go through the tiny capillaries that are seen in the urinary system. The blood entered into the kidney later moves to nephrons, where the blood is purified with the help of filters.

The waste that is obtained after the purification of the blood is then transferred to the vital substance that absorbs the bloodstream. It helps the body to manage and control the level of pressure in the blood.

Here the job of the heart is to simultaneously send the oxygenated blood all around the body and send the unwanted, discharged waste to the kidney where it helps to observe the required elements from the waste and transpose it to the urinary system.

The main work of the circulating system is to transpose the oxygenated blood to every part of the cell and provide them with sufficient nutrients.

From this system it is understandable that the similarities between circulatory and urinary system is both of the parts functions to remove waste from the body.

A n example of Lesson 16.2 modeling exponential growth and decay is find out if y =5(2)ˣ is exponential growth or decay.

One can know if a function is an exponential growth or decay when it has a as positive and b is said to be greater than 1 (to be exponential growth).

If a is said to be positive and b is said to be lower than 1 but when it is also greater than 0, we can say that it is an exponential decay.

From the above, y =5(2)ˣ is an exponential growth because the base is said to be greater than 1 and the exponent contain a positive notation.
