The image of the triangle is to be formed by rotating ΔXYZ 180 degrees about the (2, -3) as shown in the graph.
<h3>What is Geometry?</h3>
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Triangle XYZ has vertices X(0, 2), Y(4, 4), and Z(3, –1).
If the triangle is ΔXYZ. Then the image of the triangle is to be formed by rotating ΔXYZ 180 degrees about the (2, -3) as shown in the graph.

To find what a is, consider the equation v=at (v=velocity, a=acceleration, t=time interval), making a=v/t. Take the given v of 853m/s, and divide that by your time IN SECONDS, so 1.2ms=1.2*10^-3s.
a=(853)/(1.2*10^-3)=7.11*10^5 m/s^2.
Now Having F=ma, where a is your acceleration, and m=mass (which is 49*10^-3 kg),
F=(49*10^-3)(7.11*10^5)=3.48*10^4 N
Hope this helps!
Answer:
Chemical reaction.
Explanation:
Changes in color and temperature indicates a chemical reaction has taken place.
A chemical reaction involves two species combining to give a product. They are usually a product of chemical changes between two combining species.
In a chemical change;
- New kinds of products are formed
- There are heat changes accompanying such reactions.
- We can have color changes but it is not all indicative.
Answer:
Transformer
Explanation:
Transformers can increase (step up), or it can decrease (step down) voltage.
