It depends on the kind of transformation.
Dilation, rotation, reflection and translation
It means fully covered & completed.
The mean of a single number is the number itself. So the answer is 969.
It's a circle. The equation of a circle is x^2+y^2=r^2. So the equation you've given is a circle with a radius of 4 and, since there are no modifications to the x or y values, the center of the circle is located at (0,0).
In America it is math, in most European countries it is maths
Dilation, rotation, reflection and translation
A transformation is said to be rigid if it preserves relative distances.
It means fully covered & completed.
It can do, but it can go beyond that as well.
There was no single person.
Transformation in maths is when you shift a point or multiple points in terms of it's original point. Ie if you were to shift the point (2;1) about the x axis the transformed point would be (-2;1).
i think it is an exponent hard to describe without seeing
A transformation is how you move a shape from one place to another. For example rotations, translations and reflections are all ways of moving a shape.
9 if you mean only a single digit
The mean of a single number is the number itself. So the answer is 969.
To describe a particular transformation fully, it means to describe what has happened to shape B to make it into shape A. In this instance, you would start off your description with "Reflection". Next, you must identify the mirror line which is between shape B and A. Make sure to mark it in. Next, you would write Mirror Line= ?? (We will replace the ?? later). Because all transformations are on graphs with co-ordinates, you will need to work out where your mirror line lies. An example would be, Mirror Line: x=2. This means the mirror line is on the 2nd sector within the X axis. Hope this makes sense. It probably is a little confusing but with a few drawn examples it would be a lot better to understand.
There is no single mathematical formula and no single inventor. Furthermore, there are sometimes different (though equivalent) formulaefor the same calculation.
