Given:
The preimage and image of a triangle in the given figure.
To find:
The dilation scale factor.
Solution:
From the given figure it is clear that the vertices of the triangle ABC are A(-2,-2), B(-1,2) and C(2,1).
The vertices of the triangle A'B'C' are A'(-4,-4), B'(-2,4) and C'(4,2).
If a figure is dilated by factor K with (0,0) as the center of dilation, then
Let the scale factor be K, then the image of point A is:
From the given figure it is clear that the image of point A is A'(-4,-4).
On comparing both sides, we get
Therefore, the dilation scale factor is 2.
Jamestown- Why are there positive and negative interactions when cultures meet?
Answer:
B
C/15=3
Step-by-step explanation:
They devided the coconuts among 15 children
3x15 =45
45÷3 =15
So the number of coconut the kids gathered is 45
C/15=3 multiply by 15 on both side
15/1 ×c/15=3×15
C=3×15
C=45
Rational number are numbers which can be expressed in a ratio of two integers. Both numerator and denominator are whole numbers<span>, where the denominator is not equal to zero.</span>
An irrational number<span> on the other hand is a </span>number which cannot be expressed in a ratio of two integers. However there are similarities between them. For example: the product of both irrational numbers of born rational numbers can be rational number, both irrational and rational numbers can be negative and positive, and both can be expressed as a fraction.
