Answer:
<em>= 4a + 11</em>
Step-by-step explanation:
a+7+3a+4
Combine Like Terms:
= a + 7 + 3a + 4
= (a + 3a) + (7 + 4)
<em>= 4a + 11
</em>
Answer: see below
<u>Step-by-step explanation:</u>
The coordinates on the Unit Circle are (cos, sin). Since we are focused on cosine, we only need to focus on the left side of the coordinate. The cosine value (left side) will be the y-value of the function y = cos x
Use the quadrangles (angles on the axes) to represent the x-values of the function y = cos x.
Quadrangles are: 0°, 90°, 180°, 270°, 360° <em>(360° = 0°)</em>
Together, the coordinates will be as follow:

10. 99
11. 4102
