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:
Possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.
Step-by-step explanation:
Let the length of the silk fiber = x yards.
Let the number of silk fibres = a.
It is given that the silk fibers between 3 to 10 yards are combined to form a silk thread of 300 yards.
So, we get the equation,
, where 
i.e.
, 
So, the possible values of 'a' are 3, 4, 5, 6 an 10.
Thus, the possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.
