The points a b c and d lie on a straight line ab:bd = 1:4 are A line that extends to infinity on both sides and has no curves is called a straight line.AB:BC=3:4.
<h3>What do you call a straight line? </h3>
A line is simply an object in geometry denoted as an object with no width that extends on both sides. A straight line is just a line with no curves.
- AC=AB+BC=3+4=7; AC:CD=2:1, i.e. AC=2; because we get 2 different lengths for AC, we change the given ratio AC:CD to an equivalent one with AC=7 .
- As follows: AC:CD = 2 : 1 = 7 : 3.5 (multiply both sides by 3.5 ) Now we have AC:CD = 7 : 3.5 and AD = AC+CD= 7+3.5 = 10.5,, and the answer is: the ratio BC:AD = 4:10.5.

Answer:
JTextField
Explanation:
JTextField is a Swing control which can be used for user input or display of output. It corresponds to a textfield and can be included with other controls such as JLabel, JButton,JList etc. on a comprehensive user interface which is application dependent. JTextField supports a read-write mode where the user can enter a value and it also supports a read-only mode which can be used to display non-editable output to the user.
Answer:
False ( B )
Explanation:
Of the seven IT infrastructure domains The USER domain was not at risk because the User Domain is not task with handling the sharing of data or Mutual communication between users in a Typical IT infrastructure.
The domain charged with such responsibility is The LAN domain because the LAN domain is charged with the sharing of information between the USERS and maintaining good mutual communication, and since the relationship has become sour, the sharing of information between the users will suffer the most and it will be at a high risk
Answer:
No you can not tell that recursion is ever required to solve a problem.
Recursion is required when in the problem, the solution of the input depends on the solution of the subsets of the input.
Iteration is also another form of repetitive approach we follow to solve that kind of problems.
But the difference between recursion and iteration is :
- In recursion we call the function repeatedly to return the result to next level.
- In iteration certain bunch of instructions in a loop are executed until certain conditions met.
Explanation:
For example in the Fibonacci sequence problem, to find 
, we need to compute 
and 
before that.
- In case of recursion we just call the method Fibonacci(n) repeatedly only changing the parameter Fibonacci(n-1), that calculates the value and return it.
Fibonacci(n)
1. if(n==0 or n==1)
2. return 1.
3.else
4. return( Fibonacci(n-1)+Fibonacci(n-1) )
- But in case of iteration we run a loop for i=2 to n, within which we add the value of current
and 
to find the value of 
Fibonacci(n)
1. if(n<=2)
2. result = 1
3. else
4. result1 =1 and result2=1.
5. { result = result1 +result2.
6. result1= result2.
7. result2 = result.
8. }
9. output result.
