1/2(1 - cos(2x))*1/2(1 + cos(2x)) = (2 - √2) / 16
1/4(1 - cos^2(2x)) = (2 - √2) / 16
1/4(1 - 1/2(1 + cos(4x)) = (2 - √2) / 16
1/8(2 - 1 - cos(4x)) = (2 - √2) / 16
1/8(1 - cos(4x)) = (2 - √2) / 16
1 - cos(4x) = (2 - √2) / 2 = 1 - √2/2
cos(4x) = √2/2
4x = arccos(√2/2) = π/4
x = π/16
The solutions are: nπ - 15π/16, nπ - 9π/16, nπ - 7π/16, nπ - π/16.
I'm assuming they are equivalent...
Solve for m and get 3.

Answer:
7/23
Step-by-step explanation:
First you make it an improper fraction, which gets you 23/7. Then to find the reciprocal, you simply flip it over. Therefore you get 7/23.
There you go! Have a nice day. Mark brainliest if possible please ;)
Answer:
12.36%
Step-by-step explanation:
For year 1:
T(1) = 1000(1.06)¹
T(1) = 1060
After two years, t = 3
T(3) = 1000(1.06)³
T(3) = 1191.06
The percent of the increase is
[(T(3) - T(2)/T(2)]*100%
[(1191.06 - 1060)/1060]*100%
12.36%
I believe it is a parallelogram.
Reasons:
1. It is a quadrilateral. Quadrilaterals have a total amount of 360 degrees. 80+100+100+80=360
2. It has oposite sides that are equal
3. If you look at a parallelogram it has two obtuse angles and two acute.
100= obtuse angle 80= acute angle
