Answer:
θ = π n + π/2 for n element Z
Step-by-step explanation:
Solve for θ:
1 + 2 cos(2 θ) + cos^2(2 θ) = 0
Write the left hand side as a square:
(cos(2 θ) + 1)^2 = 0
Take the square root of both sides:
cos(2 θ) + 1 = 0
Subtract 1 from both sides:
cos(2 θ) = -1
Take the inverse cosine of both sides:
2 θ = 2 π n + π for n element Z
Divide both sides by 2:
Answer: θ = π n + π/2 for n element Z

Answer:
k = 31
Step-by-step explanation:
17 = (-14) + k
Add 14 to both sides
k = 31
Answer:
24*0.5=12
Step-by-step explanation:because when ever you multiply by a decimal you take that percent away from the original amount--- .5=50%, so you take away 50% of 24 and you get 12
