Answer:
Neither
Step-by-step explanation:
2,5,10,17
Differences between numbers:
2->5 (3)
5->10 (5)
10->17 (7)
There is no common difference between numbers so its neither.
a4 is 17 because that is the 4th term in the sequence.
Answer: the line goes the way the arrow is pointing.
Step-by-step explanation:
9<-18 It’s goes <<<< that way. Towards The -19
18/25 is already simplified. There is no number that can go in both 18 and 25.
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
