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:
There were 62 deaths
Step-by-step explanation:
In this question, we are asked to calculate the number of robberies in 2012.
From the question we can identify that the number of robberies were up 50% to 93. What this means is that the number is simply 150% of the old number.
Now, let’s represent the number of deaths in 2012 by x
Mathematically;
150% of x = 93
150/100 * x = 93
150x = 93 * 100
150x = 9300
x = 9300/150
x= 62
This means there were 62 deaths in the year 2012
Zero
C is the correct option.
Step-by-step explanation:
In the given graph, the given lines are parallel to each other and hence never intersect.
Now, we know that the intersection point (s) of two curves gives us the solution.
Here the lines are parallel to each other and hence do not intersect each other.
Thus, there would not be any intersection point.
Hence, the system of equations has no solution.
C is the correct option.
Hope this helps
