Radio Waves have multiple communication uses. Some of them are television and radio broadcasting, communications, and satellite transmissions.

Radio waves are not harmful to biotic life when absorbed by living matter and their transmission is unimpeded by air. Their transmission can also be absorbed, deflected, reflected, refracted, or diffracted by air molecules and the earth's surface.

Convert the algebraic expression below to C++ statement Do not use the pow function. Ans = 5x^2 + 15k + y^-2

Answers

Answer:

The C++ statement for the given algebraic expression 5x^2 + 15k + y^-2 is ( ( 5 * ( x * x ) ) + ( 15 * k ) + ( 1 / ( y * y ) ).

Explanation:

To convert the given algebraic expression 5x^2 + 15k + y^-2 into the C++ statement without using the pow function is:

In the given algebraic expression, there are three expressions combined using the + operator.

The first algebraic expression is 5x^2.

Here, x has a power of 2, and 5 is multiplied by the result of x^2. x having the power of 2 means x is multiplied itself twice. The C++ statement for this algebraic expression is (5 * ( x * x)).

The second algebraic expression is 15k.

Here, 15 is multiplied by k. The C++ statement for this algebraic expression is (15 * k).

The third algebraic expression is y^-2.

Here, x has a power of -2. it means [tex]1/y^{2}[/tex].  The C++ statement for this algebraic expression is (1/ (y * y).

The combination of all the three C++ statement is (5 * ( x * x)) + (15 * k) + (1/ (y * y).

I need help in raft survival ocean nomad I was traveling and now I can't enter the island or go back home (raft). Please help me

is solar energy reliable and powerful enough to be used in home or business​

Answers

Answer:

It all depends on what you are prepared to spend and what sort of system you install. I have both grid tie and stand alone systems installed at my home, and both work really well, although we initially had some inverter problems with the grid tie system until we decided to only use top shelf gear.

We have 6.6 kW grid tie system on the roof of the house which supplies around 3 times our requirements, and a 1.5 kW stand alone system that supplies the backyard workshop and pool pump. The grid tie system cost around $6500 to install, and the small stand alone system cost $4500 although this was designed and built by myself, so a purchased system may well be more (batteries are still expensive, but this price is coming down).

In the current configuration (top tier panels, Fronius grid tie inverter and Victron stand alone inverter and charge regulator), we have had no failures in several years, and power bills are something that happen to other people.

My advice is look at what your requirements are, then double that when you spec out your system and don’t go for the cheapest price. Buy your components based on the quality and reputation of the manufacturer, it will be expensive, but you will save money in the long run. A good manufacturer will guarantee their products for at least 12 years and you should expect to get at least 20 years of life out of them.

Explanation:

Solar energy is more than enough for any business or home, but if you want to know if it is cost effective, you need to run the numbers. It does have to be grid-tied though to provide electricity at night or when cloudy for multiple days. In most cases, batteries are not cost-effective at this time.

A regional bank implemented an automated solution to streamline their operations for receiving and processing checks/cheques

Answers

A regional bank implemented an automated solution to streamline its operations for receiving and processing checks/cheques. They would like to further enhance the solution to recognize signs of potential check fraud and alert their security teams accordingly.

Which technology could be combined with the current solution to do this?​

Answer:

Machine learning

Explanation:

The technology that could be used in combining with the current solution to do this is known as MACHINE LEARNING

Given that Machine Learning is a form of Artificial Intelligence, which is designed to possess the ability to act or mimic human beings and their functional characteristics to solve human problems.

Hence, because the regional bank prefers to streamline their processes of receiving and carrying out checks/cheques while also enhancing the solution to recognize signs of potential check fraud, then the technology they could use is called MACHINE LEARNING.

This is because Machine Learning will operate like humans to solve human problems efficiently.

Write the field for the table "BOOK" with its field type and also write the primary key for the table.

Answers

Answer:

Fields are the components that provide structure for a table. Fields in a table store the same category of data in the same data type. For example, if you have a NAME field in a table of customers, the entries for this field are all customer names and are stored as text.

A primary key is a field or set of fields with values that are unique throughout a table. Values of the key can be used to refer to entire records, because each record has a different value for the key. Each table can only have one

primary key.

The primary key of this table is the ISBN, which uniquely identifies a book. The title column relates to the book; this is the title of the book. Each row of this table is about one book.
