Answer:
- <u><em>a reflection of the line segment across the y-axis </em></u>
Explanation:
The transformations of the end points are:
Preimage Image
The means that, for every end point, the x-coordinate changes the sign and the y-coordinate remains unchanged.
That rule is:
- (x, y) → (- x, y): this is<em> a reflection across the y-axis</em>.
Keeping the y-coordinate and changing the sign of the x-coordinate is a reflection across the y -axis. It is like a mirror image, where the mirror is placed along the y-axis. The figure keeps the same distance from the y-axis (the mirror) but changes sides, which is represented by the change of x to - x, while the altitude (the y-coordinate) keeps unchanged.
<u>Answer:</u>
From the perspective of human health, the three inhuman farming practices that need to be changed are as follows:
- Use of chemical pesticides like norflurazon, phorate, chloropicrin, etc.
- Use of steroids to stimulate the growth of animals.
- Use of chemical supplements to increase animal produce.
<u>Explanation:</u>
- The use of chemical pesticides like norflurazon, phorate, chloropicrin, etc. is also responsible for killing the useful bacteria in the soil.
- The usage of steroids to stimulate animal growth causes the meat of such animals to become harmful to consume.
- The chemical supplements used to increase the yield obtained from dairy animals causes the metabolism of the animals to suffer badly.
Answer:
Construction jobs, textile production, and manufacturing are examples of the second economic sector.
Explanation:
The economic activities are divided into four major groups in accordance with their characteristics and at which level of economic development they are dominant. The four economic sectors are the primary, secondary, tertiary, and quaternary sectors. The secondary is an economic sector typical for developing countries that are in the process of industrialization.
Because these countries are rapidly industrializing and transitioning from agricultural societies, their labor force is not very skilled, so they are suitable for jobs that are of a lower level, or rather where particular skills are not required. This makes a situation where the construction, textile, and manufacturing industries prosper the most, with the labor force being abundant for them. This is a typical secondary economic sector.
Answer:
On a geologic map, if the contacts between sedimentary rock units form a bull’s-eye pattern of concentric circles, with the oldest unit in the center, the underlying structure is a syncline.
