Answer:
Option B. contraction
Step-by-step explanation:
The vertices of a pre-image are located at the points (-6, 3), (0, 0), and (3, 6).
The end image triangle has the vertices at (-2, 1), (0, 0), and (1, 2).
Here we can see that one point (0, 0) is common in both the triangles and rest two vertices in end image are changed from the pre-image.
Now we find the ratio of x and y coordinates from end and pre-image we find a ratio of in x-coordinates.
similarly for y coordinates .
Now we can say that there is a contraction in the vertices of end image about the origin (0, 0).
Therefore Option B. Contraction is the correct option.
Answer:49.5 meters
Step-by-step explanation:
It is simply 45 x 1.1 for your answer
Sounds like the situation in the sketch below...
There is a theorem that says the angle (BAD) formed by a tangent (AB) and a secant (AD) to a circle (O) is half the difference of the intercepted arcs (BD and BD'):
Triangle BAD is a right triangle, so
