The first one, bc the equation simplified equals the first one
Answer: ( 1. ) Negative Correlation.
Use bottom info to Justify answer.
Step-by-step explanation:
As x increases y decreases = Positive Correlation
As x increases y decreases = Negative Correlation
As x increases y stays the same = No Correlation.
Hope this helps. :)
Answer:
Step-by-step explanation:
Here, given :
sin 2 x - 2 sin x = 2 .... (1)
Now, by <u>TRIGONOMETRIC IDENTITY</u>:
Sin 2Ф = 2 SinФ CosФ
⇒ sin 2 x = 2 sin x cos x
Putting back the value in (1), we get:
sin 2 x - 2 sin x = 2 ⇒ (2 sin x cos x) - 2 sin x = 2
or, 2( sin x cos x - sin x) = 2
or, sin x cos x - sin x = 1
or, (sin x) ( cosx - 1) = 1
⇒ Sin x = 1 / ( Cos x - 1)
Hence,
Answer:
I think it would be 21, because 105 / 5 is 21, and if the denominator is the holder spot, it should be 21
Answer:
see the procedure
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
we have
The remaining length (L) of 120-inch rope after x inches have been cut off
we have
L ---> is the dependent variable (output variable)
x ---> the independent variable (input variable)
The linear equation is
The equation not represent a proportional relationship, because the line not passes through the origin
