Scale Factor
To dilate a figure means to resize it while maintaining its shape and proportions. This transformation involves expanding or contracting the figure from a specific point called the center of dilation, using a scale factor that determines how much larger or smaller the figure will become. For example, a scale factor greater than one enlarges the figure, while a scale factor between zero and one reduces it. The relative positions of points in the figure remain consistent, preserving the figure's overall geometry.
Take the 'reciprocal' of the given scale factor to go the other way. The 'reciprocal' of a number is 1/(the number). 3 ==> 1/3 5 ==> 1/5 1/7 ==> 7 2/3 ==> 3/2 etc.
A dilation with a scale factor of 0.5 reduces the size of the figure to half its original dimensions, resulting in a smaller figure. In contrast, a dilation with a scale factor of 2 enlarges the figure to twice its original dimensions, creating a larger figure. Therefore, the two dilations produce figures that are similar in shape but differ significantly in size, with the scale factor of 2 yielding a figure that is four times the area of the figure dilated by 0.5.
To find the scale factor of a figure to a similar figure, you can compare corresponding linear dimensions, such as side lengths or heights. Divide the length of a side of the original figure by the length of the corresponding side of the similar figure. The resulting value is the scale factor, which indicates how much larger or smaller one figure is compared to the other. Ensure that both figures are oriented similarly for an accurate comparison.
To find the surface area of the smaller figure, we can use the relationship between the volumes and surface areas of similar figures. The volume ratio of the larger figure to the smaller figure is ( \frac{2744}{729} = \left(\frac{a}{b}\right)^3 ), where ( a ) is the linear dimension of the larger figure and ( b ) is that of the smaller figure. Taking the cube root gives the linear scale factor ( \frac{a}{b} = \frac{14}{9} ). The surface area ratio, which is the square of the scale factor, is ( \left(\frac{14}{9}\right)^2 = \frac{196}{81} ). Given the surface area of the larger figure is 392 mm², the surface area of the smaller figure is ( 392 \times \frac{81}{196} = 162 ) mm².
The ratio
do managers want the contribution margin to be bigger or smaller
No it makes the figure bigger or smaller than the original
It is the smaller divided by the bigger. For 5 and 17, the 5 is 5/17 of the 17.
The two scale factors are reciprocals of one another.
it is called a outter figure shape

A scale factor of 2.
To find the scale factor, you need to compare the corresponding sides of two similar figures. The scale factor is calculated by dividing the length of a side on the larger figure by the length of the corresponding side on the smaller figure. For example, if the larger figure has a side length of 8 units and the corresponding side on the smaller figure is 2 units, the scale factor would be 8 divided by 2, which equals 4.
A dilation with a scale factor of 0.5 reduces the size of the figure to half its original dimensions, resulting in a smaller figure. In contrast, a dilation with a scale factor of 2 enlarges the figure to twice its original dimensions, creating a larger figure. Therefore, the two dilations produce figures that are similar in shape but differ significantly in size, with the scale factor of 2 yielding a figure that is four times the area of the figure dilated by 0.5.
