Answer: 3. Point F.
Step-by-step explanation:
The missing statement is: Point F' corresponds to______
- Point D.
- Point E'.
- Point F.
- Point E.
The missing picture is attached.
By definition, the original figure (The figure before the transformation) is called "Pre-image" and the figure obtained after the transformation is called "Image".
You know that the triangle is obtained by transforming the triangle ; therefore, the triangle is the Pre-Image and the triangle is the Image.
Therefore, given the point (which is a vertex on the triangle ) you can identify that its image is (which is the corresponding vertex on the triangle ).
You can also verify it by seeing the angle and the angle . Notice tthat:
Therefore, based on the explained before, you can conclude that the point corresponds to the point .
Answer:
63.57817848
Step-by-step explanation:
all will be in degrees:
cos 40 sinx - sin 40 cos x = sin(x - 40) by the formula sin(A − B) = sinA cosB − cosA sinB
sin(x - 40) = 2/5
x - 40 = arcsin(2/5)
x - 40 = 23.57817848
x = 63.57817848 degrees
The graph is decreasing because the arrow is going down or starts off high and gets lower and lower.
