Answer: Rotations, reflections, translations (A, C, and E)
Imagine you had a camera aimed at a triangular figure on a piece of paper. If you rotate the camera, then the image of the triangle appears to rotate. In reality it's the other way around. What this means is that the triangle is not changing at all. It keeps the same size, shape, area, perimeter, etc. This applies to when the camera pans left or right, ie shifts from side to side. The triangle will translate but again the triangle isn't changing at all. It's merely an illusion. Reflections are the same way. Imagine having a piece of glass or a mirror that reflects the image which is an identical copy; although everything is flipped.
Dilations are not isometries because the image is a different size then the pre-image. The same shape is maintained though. Note: the scale factor must be some number other than 1.
another note: "isometry" breaks down into "iso+metry" with "iso" meaning "same" or "equal", and "metry" meaning "measure". So if you had 2 identical yard sticks, then they are isometrical or equal in length.
Answer:
1% of 1200 is 12, so to find this we multiply 12 until we get 150
150/12 = 12.5
12.5%
6 2/5 - 3 1/4 = 63/
20
= 3 3/
20
= 3.15
Answer:3.15
Hope this helps :)
Answer:
7.5
Step-by-step explanation:
15/2
2 doesn't go into 1 so go over to the 15 and then 7 goes into 15 two times do subtract 15 and 14 and then you'll get one once you have 1 left over add a decimal next to the 7 on top right after that add a 0 next to the one then you'll get a 10 once you have a 10, you can know how much 2 goes into 10 which 5 and subtract 10 by it self then you'll get your answer 7.5
The linear function that maps the relation between kinetic energy and mass is given at the end of the question.
<h3>What is the kinetic energy of an object?</h3>
The kinetic energy of an object is given by the following formula:
E = 0.5mv².
In which:
- m is the mass of the object.
- v is the velocity of the object.
In this problem, we suppose a velocity of 2.5 m/s, hence the kinetic energy is:
E = 0.5m(2.5)² = 3.125m.
Hence the graph is plotted at the end of the answer.
