Vertical stretch by a factor of 3 and a reflection over x-axis is g(x)= -3|x|
Answer:
150
Step-by-step explanation:
15*10
Lets get rid of the 0 for now
15*1
That is 15 added to itself 0 times so it is 15
Now lets put the 0 back
and we will get
150
A dilation is a transformation, with center O and a scale factor of k
that is not zero, that maps O to itself and any other point P to P'.
The center O is a fixed point, P' is the image of P, points O, P and P'
are on the same line.
Thus, a dilation with centre O and a scale factor of k maps the original figure to the image in such a way that the<span>
distances from O to the vertices of the image are k times the distances
from O to the original figure. Also the size of the image are k times the
size of the original figure.
In the dilation of triangle TUV</span>, It is obvious that the image <span>T'U'V' is smaller than the original triangle TUV and hence the scale factor is less than 1.
</span>The ratio of the
distances from A to the vertices of the image T'U'V' to the distances
from A to the original triangle TUV is the scale factor.
The scale factor = 3.2 / 4.8 = 2/3
If you mean the measure of angle A then the answer is 28°
