Sometimes a dilation is an enlargement and sometimes it is a reduction. Explain what types of numbers for scale factors causes each.?
A scale factor whose absolute value is greater than one is an enlargement whereas if the absolute value is less than 1 it is a reduction.
What is a negative scale factor?
A negative scale factor is used to produce the image on the other side of the centre of enlargement (scaled to the absolute value of the scale factor).
A dilation is a reduction if the scale factor is?
A diliation is a reduction if the scale factor is: less than 1.
What is an enlargement with a negative scale factor?
It is a smaller shape on the other side of the centre of enlargement.
A problem in Math and you don't know how to solve it. Please help Sometimes a dilation is an enlargement and sometimes it is a reduction Explain what types of numbers for scale factors causes each?
If the dilation is >0 but <1, it is a reduction. If it is any number >1, it is an enlargement.
What type of dilation occurs with a scale factor of 14?
The type of dilation that occurs with a scale factor of 14 is enlargement. Any time the scale factor is larger than 1, it is enlargement.
What is the dilation of 22 if the scale factor is 2.5?
The dilation of 22 with scale factor 2.5 is 55.The formula for finding a dilation with a scale factor is x' = kx (k = scale factor), so x' = 2.5(22) = 55.
Sometimes a dilation is an enlargement and sometimes it is a reduction. Explain what types of numbers for scale factors causes each.?
A scale factor whose absolute value is greater than one is an enlargement whereas if the absolute value is less than 1 it is a reduction.
Is a scale factor of 1 a dilation?
No a scale factor of 1 is not a dilation because, in a dilation it must remain the same shape, which it would, but the size must either enlarge or shrink.
Every dilation has a?
Center and Scale Factor....
What is a negative scale factor?
A negative scale factor is used to produce the image on the other side of the centre of enlargement (scaled to the absolute value of the scale factor).
A dilation is a reduction if the scale factor is?
A diliation is a reduction if the scale factor is: less than 1.
Another name for scale?
Enlargement factor.
What information do you need to complete a given shape enlargement?
The scale or enlargement factor.
A transformation that proportionally reduces or enlarges a figure?
Scaling will proportionally reduce or enlarge a figure. The amount of scaling is given by the scale factor (greater than zero) If the scale factor is less than 1, the figure is reduced and it is sometimes called a contraction If the scale factor is greater than 1, the figure is enlarged, and it is called a dilation or enlargement. If a centre of enlargement is used, the distance of every point from the centre is multiplied by the scale factor. The scale factor can be negative in which case the distance to the new point is measured on the opposite side of the centre to the original point.
What is an enlargement with a negative scale factor?
It is a smaller shape on the other side of the centre of enlargement.
Does an enlargement of a photograph represent a dilation or a rotation?
Dilation
