The radius is the distance from the center to any point. The distance from (2,1) to (0,1) is of course 2. The general formula for a circle with radius r and center (a,b) is
In our case we get
In our case we get

Answer:
Part 11) ,
Part 2) 4+3i
Step-by-step explanation:
Part 11) write a recursive rule for the sequence
Let
we know that
---->
---->
---->
This is an arithmetic sequence
In an Arithmetic Sequence the difference between one term and the next is a constant, and this constant is called the common difference (d).
In this problem the common difference is equal to
therefore
A recursive rule for the sequence is
substitute the value of d
where
Part 12) What is the complex conjugate of 4-3i?
we know that
The <u><em>complex conjugate</em></u> of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign
so
we have that
the real part of the given number is 4 and the the imaginary part is -3i
so
the imaginary part equal in magnitude but opposite in sign is +3i
therefore
the complex conjugate of the given number is equal to
Answer is as attached.
