Mathematics

Answer:

Option (C)

Step-by-step explanation:

From the graph attached,

In ΔABC and ΔA'B'C',

∠A ≅ ∠A'

∠B ≅ ∠B'

Therefore, ΔABC ~ ΔA'B'C'

Corresponding sides of these triangles will be proportional.

\frac{\text{AB}}{\text{A'B'}}=\frac{\text{BC}}{\text{B'C'}}=\frac{\text{AC}}{\text{A'C'}}=\frac{2}{6}

Therefore, ratio of the sides, AC : A'C' = 1 : 3 shows that image triangle A'B'C' is a dilated form of pre-image ABC with a scale factor of 3.

Option (C) will be the correct option.

What is subjective?? (Science)
natita [175]

Answer:

Hypotheses are always made by one individual or by a limited group of scientists, and are therefore subjective—based on the prior experience and processes of reason employed by those individuals, rather than solely on objective external process. 

According to this view, human attitude is associated with human sciences; but as far as natural science is concerned there is no scope for any subjective elements. Scientific knowledge is purely objective, and it is an objective description of the real structure of the world.

Step-by-step explanation:

Pertaining to or characteristic of an individual; personal; individual: a subjective evaluation.

Phrase collocation :

  1. subjective idealism
  2. subjective test
  3. subjective brightness

Bilingual example Used as an adjective (adj.) :

  1. Whatever is subjective in you, is the truth.
  2. The answer is not easy and, in this case, it is largely subjective .
  3. Marxism is not true and is not science, but so what? The hermeneuticians tell us that nothing is objectively true, and therefore that all views and propositions are subjective.
  4. His arguments were never subjective.
  5. He took a subjective view of the problem.
  6. Grading of oral tests is quite subjective.
