Answer:

x = 7

Step-by-step explanation:

The angles are alternate interior angles, so for the lines to be parallel, the angle measures must be equal.

7x - 7 = 4x + 14

3x = 21

x = 7

What is the amplitude of y = 4sin3x?<br><br> 1/2<br> 2<br> 3<br> 4
liubo4ka [24]

The most generic sine function you can write is

y = A\sin(\omega x + \phi) + k

Of all these constant, A affects the amplitude, \omega affects the wave length, \phi and k cause horizontal/vertical translation.

In your case, A = 4,\quad \omega = 3,\quad \phi = k = 0

And we are interested in the amplitude, so we focus on A = 4

The amplitude of the standard sine function is 1, so when you multiply by A, the new amplitude is A itself. In our case A = 4, so the amplitude is 4.

whihc question is not a good survey question? dont you agree that the financial crisis is essentially over? on average how many
Neko [114]

Answer:

The correct answer would be option A, Don't you agree that the financial crisis is essentially over.

Step-by-step explanation:

A survey questionnaire is a series of question which is set formally to be asked from a specific sample of a population to gather, analyze and interpret the data obtained from the sample population. So the questions in the survey must be structured, to the point, clear, short and straight. Survey questions are desirably closed ones and the ones which do not need much explanation by the person who is doing the survey. So the first question in this question require an explanation, and also the question is not structured, clear and to the point and thus is not a good survey question. Comparatively, the second question is more structured, clear and to the point and such questions are normally desirable in the surveys.
