(a) Fermat's little theorem states that for any prime
, we have

for any integer
. Then

so 7 does indeed divide 999,999.
(b) Generalizing, we have

for positive integer
. Now, since 1 = 1001 - 1000 and
, it follows that
is its own inverse modulo 1001, i.e.

This means

which is what we wanted to show.

Answer:
Central angle of θ


Step-by-step explanation:
Suppose a sector of a circle with radius r has a central angle of θ.
Since a sector is a fraction of a full circle, the ratio of a sector's area A to the circle's area is equal to the ratio of the central angle of θ to the measure of a full rotation of the circle.
A full rotation of a circle is 2π radians.
This proportion can be written as: 
Multiply both sides by 

Simplify to get:

Where θ is the measure of the central angle of the sector and r is the radius of the circle.
Answer:
A biconditional statement is a combination of a conditional statement and its converse written in the if and only if form. Two line segments are congruent if and only if they are of equal length. ... A biconditional is true if and only if both the conditionals are true. there??
