Type the equation for the graphbelow.Pi/3 2piy = [?] sin([ ]x)
Pie

To find the equation of the graph, what we do is to recognize some characteristics of a sine function:

- Amplitude: The amplitude of the sine function is the distance from the middle value or line running through the graph up to the highest point. In this case, the amplitude is 1.

- Period: The period of a sine function is defined as the length of one complete sine wave or one complete cycle of the curve. It can be found using the equation: P=2pi/B.

Why are these characteristics important?

Because the sine function has the following general form:

In this problem, we have A=1 and we know that the period equals 2pi/3. So,

Therefore, the equation of the graph is:

What is the coefficient of x?
belka [17]

Answer:

Step-by-step explanation:

+ We have: Divided polynomials have degree 5, division polynomials have degree 1, so the polynomial will have degree 4.

Then -1          -2         -1           - 5               -10 are coefficients for

         x^4      x^3       x^2        x           term constant

So the coefficient of x is -5

Hey can you please help me posted picture of question
Gennadij [26K]

 We have the following equation:
 4x2 + 3x-3 = 0
 Using the resolver we have:
 x = (- b +/- root (b2 - 4ac)) / 2a
 Substituting values we have:
 x = (- (3) +/- root ((3) 2 - 4 (4) (- 3))) / 2 (4)
 Rewriting:
 x = (- 3 +/- root (9 + 48)) / 8
 x = (- 3 +/- root (57)) / 8
 The results are:
 x = (- 3 + root (57)) / 8
 x = (- 3 - root (57)) / 8
 Answer:
 
x = (- 3 + root (57)) / 8
 
x = (- 3 - root (57)) / 8
 
option D and F
