The scale factor is 1.5. The dilation rule is : (x,y)-------(.15x,1.5y)
Step-by-step explanation:
Dilation is a transformation that maps an object to an image of the same shape as the original object to form a different size image.When a larger image is produced it's called an enlargement where as when a small image is produced, it's called a reduction.
The rule of dilation, with center as the origin follows;
(x,y)------(sx,sy) where s is the scale factor. To find the scale factor, select one of the vertices of the object and of the image at divide the coordinate of image with that of object.
Taking O(2,16) and O'(3,24), the scale factor will be;
s*2=3
2s=3
s=3/2 =1.5
or
s*16=24
16s=24
s=24/16=3/2=1.5
The scale factor is 1.5, hence the dilation rule is;
(x,y)-------(.15x,1.5y)

Answer:
So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is -3/2°c
T = To + (-3/2°c)x
Where x is the fraction of 4 in hours
Step-by-step explanation:
Its a very simple Expression.
First we consider the first temperature at first time which is 0°c at 12 noon which I initial time, i.e t= 0.
For every four hour change , the temperature adds -3/2°c .
So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is -3/2°c
The expression to know the temperature is
T = To + (-3/2°c)x
Where x is the fraction of 4 in hours
