Answer:

Amplitude =2 ,

Time period =   \frac{2\pi }{1}.

Phase shift =  π.

Step-by-step explanation:

Given :  f(x) = 2 sin(x + π) − 4.

To find : What are the amplitude, period, phase shift, and midline.

Solution : We have given that f(x) = 2 sin(x + π) − 4.

Standard form of sine function : y=Asin(Bx+C) + D.

Where, A = amplitude , Time period =  \frac{2\pi }{B},  C = phaseshift

Midline , D = vertical shift.

On comparing

amplitude =2 ,

Time period =   \frac{2\pi }{x}.

Phase shift =  π.

Therefore, amplitude =2 ,

Time period =   \frac{2\pi }{1}.

Phase shift =  π.

Given that f(x)=2sin(x+π), the standard form of sine function is y=A=sin(Bx+C), with:
A=amplitude
2π/B=period
C/B=phase-shift
A=2=amplitude
B=1
period=2π/B=2π/1=2π
C=2π/1=2π

Which situation represents the equation: 5x - 18 = 42
Nookie1986 [14]
The correct answer is C. She makes an amount of money per hour x, then she works five hours so 5x, she then spends 18 on pizza so 5x-18, and then has 42 left over. 5x-18=42

I don't know how to do this. Any help?
Brut [27]

Answer:

cos 37=x/b (second one)

sin 37= a/b (third one)

tan 37=a/x (sixth one)

Step-by-step explanation:

Cos is defined by the adjacent side over the hypotenuse. Cos 37 would be x/b. Clearly, that is option 2. Sin is defined by opposite over hypotenuse. Sin 37 would be a/b. That is the 3rd option. Tan is defined by opposite over adjacent. Tan 37 would be a/x or the 6th option.

The difference between the square of two numbers is five. Twice the square of the second number is subtracted from three times t
svet-max [94.6K]
Let us assume the first number to be = x
Let us assume the second number to be = y
Then
x^2 - y^2 = 5
x^2 = y^2 + 5
And
3x^2 - 2y^2 = 19
Multiplying the first equation by -2, we get
- 2x^2 + 2y^2 = - 10
Now subtracting the two equations, we get
x^2 = 9
x = 3
Putting the value of "x" in the first equation, we get
(3)^2 - y^2 = 5
9 - y^2 = 5
y^2 = 4
y = 2

I hope that the procedure is clear enough for you to understand and this is the answer that you were looking for.
