Answer:

<u>B.</u><u> It contains tables with fields that are associated with one another.</u>

<em>Further explanation of concepts:</em>

What is a relational database?

A relational database is a database that stores data in the form of tables. The tables are then linked together by relationships. This makes it easy to access data in the database and to create new relationships between data.

What are queries?

Queries are how you search for and manipulate data in a relational database. Queries can be used to find specific data, to update data, or to delete data.

miskamm [114]

Answer:

  • 1. <em>For the amount to double</em>: <u>9.37 years</u>
  • 2. <em>For the amount to triple</em>: <u>14.85 years</u>

Explanation:

The equation for continuosly compounded interest is:

  • F=P\times e^{rt}

Where:

  • P is the amount that you invest today: $1,300
  • F is the value after t years: the double or triple of $1,300
  • r is the annual interest rate: 0.074

<u>1. For the amount to double:</u>

Substitute the values and solve for t:

             2\times \$1,300=\$1,300\times e^{0.074t}\\ \\ 0.074t=\ln 2\\ \\ t=\ln 2/0.074=9.37years

<u>2. For the amount to triple:</u>

<u />

            3\times \$1,300=\$1,300\times e^{0.074t}\\ \\ 0.074t=\ln 3\\ \\ t=\ln 3/0.074=14.85years

Nastasia [14]

The exact meaning of the signals exchanged between a sender and a receiver is called as a Network protocol.

<h3>What Is a Network Protocol?</h3>

A network protocol is a set of rules that determine how data is transmitted between different devices in the same network.

Because of the Network protocols we can easily communicate with people all over the world, and thus play a critical role in modern digital communications.

Similar to the way that speaking the same language simplifies communication between two people, network protocols make it possible for devices to interact with one another because of predetermined rules built into devices’ software and hardware.

Neither local area networks (LAN) nor wide area networks (WAN) could function the way they are doing today without the use of network protocols.
