The composition of two rotations about the same point (Z) is the sum of the rotations. This can be proved using the matrix versions of the rotations.
This means
where
R=rotation operator
z=centre of rotation
t1,t2 are angles of rotation
In this particular case, the composition is commutative, i.e. order does not matter because addition of the angles is also commutative.
Thus substituting values, t1=170, t2=100
So the result of the composition is a rotation of 270 degrees about Z from the original position, which is also equal to a rotation of -90 degrees.

Answer:
0.25 = one time charge
Step-by-step explanation:
Given that:
Charging pattern of store for scanning documents :
(One time fee + fixed amount per page scanned)
The equation:
y=0.10x+0.25 ; gives the total cost of scanning x document pages
Comparing the equation and the charging pattern :
y = total cost
0.10 = fixed cost per page
x = number of pages scanned
0.25 = one time charge(not dependent on number of pages to be scanned).
