Answer:
The correct options are (b) and (d)
There are two the same and correct options.
The name of the shape on the right is because it is the pre-image of the shape on the left.
Explanation:
A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.
A pre-image or is the two-dimensional shape before any transformation.
The image is the figure after transformation.
The five transformation's factors are:
Shear, Rotation, Reflection, Translation and Dilation.
Answer: Money
Explanation:
Both money and energy are part of a cycle.
What does this mean?
Energy is not created nor destroyed, it is transformed into other forms of energy (for example: thermal energy, acoustic energy, kinetic energy, among others). Something similar happens with the flow of money in economic transactions, in which <u>money is exchanged for products, work or services and continues its flow in the market.</u>
<u />
Therefore, energy is a physical quantity with properties somewhat similar to <u>money</u>.
Answer: 0.8
Explanation:
The efficiency is defined as the ratio of total imput energy that is actually utilized to the end of the device.
So if we have a total transfer of 1500j of energy, and 1200j are used to heat the thing inside the kettle, 300j are not used to the actual function of the kettle.
So the efficiency is n = 1200j/1500j = 0.8
This means that a 80% of the energy imput is actually used to heat the kettle.
Answer:
Time period, T = 403.78 years
Explanation:
It is given that,
Orbital distance,
Mass of the Earth,
Mass of the planet,
Let T is the orbital period of this planet. The Kepler's third law of motion gives the relation between the orbital period and the orbital distance.
or
T = 403.78 years
So, the orbital period of this planet is 404 years. Hence, this is the required solution.
