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).
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.
i think it is an exponent hard to describe without seeing
9 if you mean only a single digit
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.
The mean of a single number is the number itself. So the answer is 969.
There is no single mathematical formula and no single inventor. Furthermore, there are sometimes different (though equivalent) formulaefor the same calculation.
