Answer:
θ = π/3, 5π/3
Step-by-step explanation:
2 cos θ - 1 = 0
2 cos θ = 1
cos θ = 1/2
θ = π/3, 5π/3
Answer: 53.40
Step-by-step explanation:
Tax = 7% of 43.45 = 3.04
Tip = 15% of (3.04 + 43.45) = 6.91
Total = 43.45 + 3.04 + 6.91
First look at the points and find their x and y values. So we have:
(-3,3), (0,0), (3,3)
Next separate the x values and the y values
x values: -3, 0, 3
y values: 3, 0, 3
The x values are your domain and the y values are are range
So the answer is b
