8 0

1) Either \ell \parallel p or \ell ∦ p (only two possibilities)

2) Assume \ell \parallel p (one of two possibilities)

3) \angle 1 \cong \angle 2 (if two parallel lines are cut by a transversal, the corresponding angles are congruent)

4) But \angle 1 is not congruent to \angle 2 (given)

5) So \ell ∦ p (only other possibility)

Anyone know the answer to this?
kiruha [24]

Answer:

42

Step-by-step explanation:

Angle ABD = Angle CBD + Angle ABC

You know ABD is 70, CBD and ABC are in terms of x

70 = 5x + 13 + 3x + 33

70 - 13 - 33 = 8x

24 = 8x

3 = x

Replacing x in Angle ABC:

3 * 3 + 33 = 42

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.

Solve the decay equation y' = -ky using the integrating factors method. Show work
Alex777 [14]

Answer:

y=\frac{c}{e^{kx}}

Step-by-step explanation:

\frac{\mathrm{d} y}{\mathrm{d} x} =-ky

\frac{\mathrm{d} y}{\mathrm{d} x} +ky=0

comparing with equation

\frac{\mathrm{d} y}{\mathrm{d} x} + Py=Q(x)

I.F.= e^{\int P dx}

I.F.= e^{\int k dx}

I.F.= e^{kx}

y=\frac{1}{I.F.} ( \int {Q(x)}  dx  +c)

y=\frac{1}{e^{kx}} ( \int {0}  dx  +c)

y=\frac{c}{e^{kx}}
