Answer:
The transformation is called Translation.
Step-by-step explanation:
We have different types of transformation:
Translation: A translation or slide is an isometry in which all points of a figure move the same distance and in the same direction.
Reflection: A reflection is an isometry in which the preimage and the image have opposite orientations. In other words, the image appears backwards.
Rotation: A rotation is an isometry in which a figure has been rotated or turned around a point called center of rotation.
Dilation: A dilation could be an enlargement or a reduction.
In Geometry, "Translation" simply means Moving without rotating, resizing or anything else, just moving.
To Translate a shape: Every point of the shape must move;
the same distance
in the same direction.
So, in this question XYZ translate to since every point move in the same distance and same direction.
Answer:
A
Step-by-step explanation:
The profit for selling <em>x</em> pairs of shoes is given by:
And we want to determine the number of pairs that needs to be sold in order to maximize profit.
Since the function is a quadratic with a negative leading coefficient, the maximum profit will occur at its vertex point. The <em>x-</em>coordinate of the vertex of a quadratic is given by:
In this case, <em>a</em> = -4, <em>b</em> = 32, and <em>c</em> = -39. Substitute and evaluate:
So, in order to maximize profit, only four pairs of sohoes should be sold.
Our answer is A.
