Answer:C
Step-by-step explanation:
A.B.C+A.B'.C+A'.B.C+A.B.C'
By distributive law : A.B.C+A.B.C' = A.B(C+C')
By complement law: C+C'=1, so
A.B(C+C')=A.B
Therefore the answer will be A.B'.C+A'.B.C+A.B
Answer: x = 9 is the x-intercept. Step-by-step explanation: We have given the coordinates (-6,10) and (12,-2).

Answer:
The terminal point is (1, 0) ⇒ D
Step-by-step explanation:
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.
- The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0
- The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1
- The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0
- The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1
In a unit circle
∵ Ф = 2π radians
∵ 2π radians = 360°
→ By using the 1st rule above
∴ The terminal point is (1, 0)
