For maximum cardinality we are most interested in either 1 or many or (1/M), because maximum cardinality defines the types of relationships. For minimum cardinality we are most interested in either 0 or 1 or (0/1), because minimum cardinality defines if the relationship is mandatary or optional. Quite often the maximum cardinality is clear. But minimum cardinality is based on the context or business rules. If we examine the cardinality from student to course.


a. What would you say is the maximum cardinality?

b. What would you say is the minimum cardinality?

c. What does it imply/require if you choose the minimum cardinality to be 0 or 1? Explain.

To promote economic growth and improve quality of life, infrastructure development entails building the fundamental support systems.

Transportation, communication, sewage, water, and educational systems are a few examples of infrastructure. A region's economic growth and prosperity depend on infrastructure investments, which are frequently expensive and capital-intensive.

Result for the phrase "infrastructure development" Infrastructure projects include making new roads, creating new power plants, maintaining sewage systems, and supplying public water sources. Public infrastructure projects are the responsibility of the federal government or the state governments of a nation.

Infra- means "below," hence infrastructure is the "underlying structure" of a nation and its economy, i.e., the permanent fixtures required for its operation. Roads, bridges, dams, water and sewage systems, railways and subways, airports, and harbors are a few examples.

Named ranges are a very important tool in Microsoft Excel. It is used in assigning a name to a particular number of cells. It is great for automation and makes formula much easy to understand and use.

One way to create named ranges is theory the Name Box.

To create named ranges in the design marketing sheet we do this;

1) We click on cell B8 and then navigate to the name box at the top right corner of the sheet just above the column A.

•The name box is where the cell address of any cell that is active is displayed.

•You would see that “B8” is displayed on the name box.

• Double click on the name box and type in the appropriate name, in this case - Design_Fee.

• Press enter and you have your named range.

You do the same for the other named ranges.

Note that: Named ranges must contain letters, numbers or underscore.

The given statement "Combining data across vertical partitions is generally more difficult than combining across horizontal partitions" is true because vertical partitioning involves storing data across multiple tables with different sets of columns, while horizontal partitioning involves splitting data into rows in the same table.

When it comes to databases, data partitioning or sharding is the process of dividing a large database into smaller and more manageable parts. The process of data partitioning makes it simpler to manage databases, particularly large databases. A partition may be a block of records or a portion of a database table.

In the case of horizontal partitioning, rows with identical values are divided into various parts of a table. A table can be divided into several parts, and each partition may be saved in a separate database, making it easier to manage. A table is divided into several pieces in vertical partitioning, with the table's columns being separated into separate tables.

It's generally more challenging to combine data across vertical partitions since it necessitates combining information from different tables. It is, therefore, correct that combining data across vertical partitions is generally more difficult than combining across horizontal partitions, according to the provided statement.

Answer:

\(A_{big} = 1143.33cm^2\)

Explanation:

The given parameters are:

\(V_{small} = 1080\)

\(V_{big} = 1715\)

\(C_{small} = 840\)

Required

Determine the curved surface area of the big cone

The volume of a cone is:

\(V = \frac{1}{3}\pi r^2h\)

For the big cone:

\(V_{big} = \frac{1}{3}\pi R^2H\)

Where

R = radius of the big cone and H = height of the big cone

For the small cone:

\(V_{small} = \frac{1}{3}\pi r^2h\)

Where

r = radius of the small cone and H = height of the small cone

Because both cones are similar, then:

\(\frac{H}{h} = \frac{R}{r}\)

and

\(\frac{V_{big}}{V_{small}} = \frac{\frac{1}{3}\pi R^2H}{\frac{1}{3}\pi r^2h}\)

\(\frac{V_{big}}{V_{small}} = \frac{R^2H}{r^2h}\)

Substitute values for Vbig and  Vsmall

\(\frac{1715}{1080} = \frac{R^2H}{r^2h}\)

Recall that:\(\frac{H}{h} = \frac{R}{r}\)

So, we have:

\(\frac{1715}{1080} = \frac{R^2*R}{r^2*r}\)

\(\frac{1715}{1080} = \frac{R^3}{r^3}\)

Take cube roots of both sides

\(\sqrt[3]{\frac{1715}{1080}} = \frac{R}{r}\)

Factorize

\(\sqrt[3]{\frac{343*5}{216*5}} = \frac{R}{r}\)

\(\sqrt[3]{\frac{343}{216}} = \frac{R}{r}\)

\(\frac{7}{6} = \frac{R}{r}\)

The curved surface area is calculated as:

\(Area = \pi rl\)

Where

\(l = slant\ height\)

For the big cone:

\(A_{big} = \pi RL\)

For the small cone

\(A_{small} = \pi rl\)

Because both cones are similar, then:

\(\frac{L}{l} = \frac{R}{r}\)

and

\(\frac{A_{big}}{A_{small}} = \frac{\pi RL}{\pi rl}\)

\(\frac{A_{big}}{A_{small}} = \frac{RL}{rl}\)

This gives:

\(\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{L}{l}\)

Recall that:

\(\frac{L}{l} = \frac{R}{r}\)

So, we have:

\(\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{R}{r}\)

\(\frac{A_{big}}{A_{small}} = (\frac{R}{r})^2\)

Make \(A_{big}\) the subject

\(A_{big} = (\frac{R}{r})^2 * A_{small}\)

Substitute values for \(\frac{R}{r}\) and \(A_{small}\)

\(A_{big} = (\frac{7}{6})^2 * 840\)

\(A_{big} = \frac{49}{36} * 840\)

\(A_{big} = \frac{49* 840}{36}\)

\(A_{big} = 1143.33cm^2\)

Hence, the curved surface area of the big cone is 1143.33cm^2

Answer:

"3 to 4"

Explanation:

Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties. One of the most widely used communication channel or medium is an e-mail (electronic mail).

An e-mail is an acronym for electronic mail and it is a software application or program designed to let users send and receive texts and multimedia messages over the internet.

An email signature can be defined as a group of texts (words) that a sender adds to the end (bottom) of his or her new outgoing email message. It is considered to be a digital business card that gained wide acceptance in the 21st century. Also, an email signature is a good etiquette in all formal conversations because it provide the recipient some level of information about the sender of an email message.

Ideally, an email signature should be three to four lines and must contain informations such as name, website address, company name, phone number, logo, catch phrase or quote, social icons, etc.

Additionally, you shouldn't place an email signature at the top or anywhere else in the email except at the bottom, immediately after the closing line.
