To be a function every input value can only have one output value
In the given problem the input value 12 has two different output values so this cannot be a function.
Answer: the relation is not a function because an input has two different outputs.
Answer:
The area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
Step-by-step explanation:
The Area is basically a measure of how much space in square units there is inside an object.
As the shape is shown on the centimeter grid.
- The shape clearly occupies the space of 5-centimeter squares.
We also know that If the scale factor > 1, the image is enlarged.
As we know to determine the area of the shape after it has been enlarged by scale factor 2, all we need to do is to multiply the area of the original shape by 2.
The area of original shape = 5 cm²
The area of the shape after the dilation by a scale factor 2 = 5 × 2 = 10 cm²
Thus, the area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
The scale factor of the dilation of polygon ABCD to polygon PQRS is: 3/2.
<h3>How to Determine the
Scale Factor of a Dilation?</h3>
Dilation means the enlargement or reduction of a polygon. If a polygon is enlarged, the new image formed after dilation is bigger than the original image. If the dilation is a reduction, the new image formed is smaller than the original image. The formula for determining the scale factor of a dilation is given as;
- Scale factor = Dimension of new image / corresponding dimension of original image.
We have the following:
Dimension of new image after dilation = PS = 3 units
Corresponding dimension of original image before dilation = AD = 2 units
The scale factor of the dilation = 3/2
In conclusion, the scale factor of the dilation of polygon ABCD to polygon PQRS is: 3/2.
