Answer:
Relationship vs N-ary Relationship
Explanation:
It is not part of the design choice in ER model because N-ary reflects an indefinite form or better still creates an identifying attribute in an ER relationship. Example is the process of creating an auto-generated ID value
Give the type and value of each result of the following Java expressions. a. (5 / 2) * 2.0 type is float value is 4.0 b. (5/2.0) * 2 type is integer value is 5c. "1.3" + "5.2" type is string value is 1.35.2d. 1 + 7.0 + "2" + "x" this will produce an error because we cannot add variables of different type
Answer:
Place holder
Explanation:
In computer programming, placeholder is a word, character or series of characters that is used to take up the space until the time when the space is actually needed. It is widely used in the sign up or login forms for web and mobile applications. For example, First Name, Last Name etc.
A programmer might have an idea that he will require this number of characters or values but he don't knows what the input will be, that’s why he uses the place holder.
Hope it helps!
Circles
Area of Circle is 
Total percentage increase in the area of the modified circle is 69%
Explanation:
(a) Given the diameter of the circle be d
Then the radius of the circle = r = d/2
and the area of the circle is given by:
Area(A) = 
A = 
A =
The area of circle is
(b)
The increase in percentage while changing the dimensions is given by the formula :
Total % increase = a% + b% - (a% * b%)/100
Where ,
a% is the percentage increase in side a
b% is the percentage increase in side b
Let the percentage increase in radius is : a%
Since a% = b%
So the formula is
Total increase % = a% + a% + (a% * a%)/100
Given here the diameter of the circle increases by 30% so a =30
Therefore, putting the value of a in the formula
Total increase % = 30% + 30% + (30% *30%)/100
Total increase % = 60% + 9%
Total increase % =69%
Therefore the total percentage increase in the area of the modified circle is 69%
