Answer:
The perfect square ( x -1 )² = 2
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given equation x² - 2 x = 1
⇒ x² - 2 x + 1 -1 = 1
⇒ x² - 2x + 1² = 1 +1
⇒ ( x -1 )² = 2
Answer:
g(-1) = -1
g(1) =5
Step-by-step explanation:
g(x) = x^3 + (x + 1)^2
If x=-1 substitute this into the equation
g(-1) = (-1) ^3 + (-1+1)^2
g(-1) = 1+0 =-1
If x=1 substitute this into the equation
g(1) = (1)^3 + (1+1)^2 = 1+2^2 = 1+4 =5
The reference angle is the angle that always uses the x-axis as a frame of reference. The reference angle is the smallest angle between the terminal side and the x-axis.
In the 1 st Quadrant: reference angle is the same ( x ).
In the 2nd Quadrant: 180° - x.
In the 3rd Quadrant: x - 180°.
In the 4th Quadrant: 360° + x.
An angle that measures 305° is in the 4th Quadrant:
360° - 305° = 55°
Answer: the reference angle is 55°.
