The additive inverse is a number, when added to another number, yields 0.
Its basically the opposite number.....same number, different sign.
so if the number m and 58 are additive inverses, then m = -58 <==
because -58 + 58 = 0
There are four main types of transformations: translation, rotation, reflection and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage.
First, find the fraction of the circumference represented by central angle 7pi/8:
7pi/8
--------
2pi
Then find the circumference; it is C = 2 pi r, or 2pi(6), or 12 pi units
Then the arc length is 7pi/8 7
-------- * 12 pi = -------- units, or 21/4 units, or 5 1/4 units.
2pi 16 pi
