Minimize any apps/webpages on it you have open (your background has to be visible), left click with the mouse, hit Personalize, and it should have Backgrounds on the page if you scroll down. You can hit Browse to look through your files on the desktop for what you want.
A: SSD, HDD, CPU or RAM
Whether you go with the faster SSD or slower but larger HDD, keep in mind you may end up needing a drive large enough to run a dual boot system if you plan on coding in multiple environments. Virtualization of other operating systems is another option, but that requires a fast CPU and a large amount of RAM to work well.
B: Ram because its larger than the others, and will work better.
C: i don't really have a suggested system but here
You may appreciate the seamless experience iOS offers, the flexibility of Android or the familiarity of Windows with your everyday PC. It might take some time to acclimate to a new system, so it may be best to stick with what you know.

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%
Answer:
(c) the dynamic type of reference will determine which of the methods to call.
Explanation:
Polymorphism in Object Oriented Programming typically means the same method name can cause different actions depending on which object it is invoked on. Polymorphism allows for dynamic binding in that method invocation is not bound to the method definition until the program executes.
So in the case of Animal superclass and Mammal subclass, both having a method called eat() with identical signatures and return types, depending on which reference, the correct method eat() will be called dynamically upon execution.
For example, if we have the following;
================================
<em>Mammal mammal = new Animal();</em>
<em>mammal.eat()</em>
================================
The eat() method that will be called is the one in the Mammal subclass.
However, if we have;
================================
<em>Animal animal = new Animal();</em>
<em>animal.eat()</em>
================================
The eat() method of the Animal superclass will be called.
