Answer:
Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate platform independence.
Step-by-step explanation:
Hierarchical layers of abstraction in computers:
Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate platform independence.
In Hierarchical layers, users work independently at each level of the hierarchy.
example:
Abstraction in computing is language abstraction
Development of programming languages from machine language to assembly language and then high-level language is an example of Hierarchical layers of abstraction. Here each stage is a base for the next stage.
we know that
the standard form of the equation of the circle is
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have
<u>Convert to standard form</u>
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square twice. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
the center of the circle is 
the radius of the circle is 
therefore
<u>the answer is</u>
the radius of the circle is
