Answer:
The answer is "Option c".
Explanation:
In Java programming, the API stands for "application programming interface", which is also known as the lists of all classes in the JDK. It contains all packages, classes, and interfaces, with their techniques, fields. It is a built-in class, which gives the programmer a great deal of usability, and correct choices can be described as follows:
In option a, It is correct because it imports the package to use API. In option b, It allows you to "re-invent the wheel" by developers, that's why it is correct.Dr. Garcia is a business professor at a large state college.

Common concerns with backups are disk failure, lack of redundancy, and the necessity of future growth of disk capacity. Which backup method adresses these concerns and has multiple levels of use depending on how you want to prioritize features like performance, capacity, or reliability
Answer:
RAID Array
Explanation:
Backups are needed in the IT industry to take care of some harm that can affect data resulting in its lose. RAID is the acronym for Redundant Array of Independent Disks. RAID combines multiple physical disks into a large virtual disk. It has different levels which range from 0, 1, 5, 6, and 10.

(Enter your answer using interval notation.) Changed: Your submitted answer was incorrect. Your current answer has not been submitted.
Answer:
The answer to this question can be defined as follows:
Explanation:
Given value:
[tex]x = t^2 + 5......(1)\\\\ y = t^2 + 5t........(2)[/tex]
To find:
[tex]\bold {\frac{dy}{dx} \ \ \ and\ \ \ \frac{d^2y}{dx^2} = ?}[/tex]
Differentiate the above equation:
equation 1:
[tex]\frac{dx}{dt}= 2t.......(1)\\[/tex]
equation 2:
[tex]\frac{dy}{dt}= 2t+5[/tex]
Formula:
[tex]\frac{dy}{dx}= \frac{\frac{dy}{dt}}{\frac{dx}{dt}}\\\\[/tex]
[tex]\boxed{\bold{\frac{dy}{dx}=\frac{2t+5}{2t}}}[/tex]
To calculate the [tex]\bold{\frac{d^2y}{dx^2}}[/tex] we Differentiate the above equation but before that first solve the equation:
Equation:
[tex]\frac{dy}{dx}=\frac{2t+5}{2t}[/tex]
[tex]=\frac{2t}{2t}+\frac{5}{2t}\\\\= 1+\frac{5}{2t}\\\\=1+\frac{5}{2} t^{-1} \\[/tex]
Formula:
[tex]\bold{\frac{d}{dx} \ x^n = nx^{n-1}}[/tex]
[tex]\frac{dy^2}{dx^2}= 0+\frac{5}{2} (-1 t^{-2})\\\\[/tex]
[tex]= -\frac{5}{2} t^{-2}\\\\= -\frac{5}{2 t^2} \\\\[/tex]
[tex]\boxed{\bold{\frac{d^2y}{dx^2}=-\frac{5}{2t^2}}}[/tex]

The barometric height in a town is 65cmHg. Given that the standard atmospheric pressure
is 76cmHg and density of mercury is 13600kg/m", determine the altitude of the town. (Density of
(3mks)
air is 1.25kg/mº).
Answer:
Altitude of the town(h1) = 1,196.8 m
Explanation:
Given:
Height of barometer(h) = 65 cm Hg = 0.65
Standard atmospheric pressure = 76 cm Hg = 0.76
Density of mercury(Pm) = 13,600 kg/m³
Density of air (Pa) = 1.25 kg/m³
Find:
Altitude of the town(h1)
Computation:
Pressure due column = Δp mercury column
(Pa)(h1) = (Pm)(h)
(1.25)(h1) = (13,600)(0.76-0.65)
(1.25)(h1) = 1,496
Altitude of the town(h1) = 1,196.8 m

What process is used to convert numbers between the binary system and the decimal system? (A.)Enter the number in a calculator, divide by 2, and multiply by 10.,(B)Convert each binary number to a letter, then use the letter’s place in the alphabet as the decimal representation ( e.g., A = 1, B = 2),(C.)Add up the digits in the binary number and place the sum behind a decimal point,(D.)Look up the number on a binary-to-decimal conversion table.
Answer:
(D.)Look up the number on a binary-to-decimal conversion table.
Explanation:
Though there are other ways of converting binary-to-decimal but from the given list of options, the best option that describes this conversion is option D.
Analyzing each of the options;
Option A
A binary number can't be converted to decimal by merely dividing it by 2 and multiplying the result by 10;
Take for instance; 11 in binary;
Divide by 2
11/2 = 5.5
Multiply result by 10
5.5 * 10 = 55
This final outcome is incorrect; as 11 in binary = 3 in decimal
Option B
This is also incorrect because as there is no room for alphabets in binary representation of numbers
Option C
This will also give an incorrect result;
Take for instance 11
Add up the digits
1 + 1 = 2
Place a decimal point behind;
This gives 2. or 2.0
This final outcome is incorrect; as 11 in binary = 3 in decimal
Option D
Looking up the number on a conversion table gives the accurate result
There are different types of conversion process. The process used to convert numbers between the binary system and the decimal system is to Look up the number on a binary-to-decimal conversion table.
Binary to decimal conversion is often done to show a number that is listed out in binary number system to its equivalent usually in decimal number system.
For easy conversion, one can Divide the binary number by 2 and write out the remainder. Thereafter you can divide by 2 again and write remainder and this process continue till the last remainder becomes 1 .
After that write all the remainders in the (0 , 1) order. With this, the decimal is converted into binary.

Referential integrity states that:______.
A. Something assigned to an attribute when no other value applies (N/A) or when the applicable value is unknown;
B. Values of an attribute must be taken from a pre-defined domain;
C. No primary key attribute (or component of a primary key) can be null;
D. Each foreign key value MUST match a primary key value in another relation or the foreign key value must be null;
Answer:
D. Each foreign key value MUST match a primary key value in another relation or the foreign key value must be null.
Explanation:
In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.
Basically, there are four (4) types of integrity constraints and these are;
1. Key constraints.
2. Domain constraints.
3. Entity integrity constraints.
4. Referential integrity constraints.
Referential integrity states that each foreign key value must match a primary key value in another relation or the foreign key value must be null.
For instance, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.
Hence, the referential Integrity constraints ensures that the relationship between the data in a table is consistent and valid.

The properties that Andy must add to his code to accomplish his goal is (B), border-collapse: separate.
What is border-collapse?The border-collapse property in CSS determines how the borders of table cells are collapsed. The default value of border-collapse is collapse, which means that the borders of adjacent cells are merged together. To make the borders of the cells in Andy's table distinctly visible, he needs to set the border-collapse property to separate.
The other possible answers are incorrect. The border-spacing property determines the amount of space between the borders of adjacent cells. The border-spacing: initial value sets the border spacing to the default value, which is 0 pixels.
