Answer:
Only points on the circle satisfy the given inequality.
Step-by-step explanation:
Given: Unit circle
To find: portion of the unit circle which satisfies the trigonometric inequality
Solution:
In the given figure, OA = 1 unit (as radius of the unit circle equal to 1)
= side opposite to
/hypotenuse
= side adjacent to
/hypotenuse
So, coordinates of A =
For any point (x,y) on the unit circle with centre at origin, equation of circle is given by
Put
So, satisfies the equation
For points inside the circle,
For points outside the circle,
So, only points on the circle satisfy the given inequality.
Check the picture below.
as we can see in the picture, the lengths for YZ and ZX are very straight, let's get the side YX
Answer: -0.64
Step-by-step explanation:
We know that the coefficient of determination in a simple linear regression model is denoted by , which gives the proportion of the variance in the dependent variable that is predictable from the independent variable.
Given, the coefficient of determination in a simple linear regression model is 64%.
i.e.
As there is negative relation between the dependent and independent variables.
Then, the correlation coefficient = -0.64
