The first situation describes an arithmetic sequence, where the number of people that got the text about the game is increasing by 8 everyday.
After day 1, 8 perple were aware of the game. After day 2, 8 + 8 = 16 people were aware, and after day 3, 8 + 2(8) = 8 + 16 = 24 people were aware.

For the movies, this describes a geometric sequence, where the number of people that got the text about the movie is increasing by a power of 8.
After day 1, 8 people were aware of the movie. After day 2, 8 + 8^2 = 8 + 64 = 72 people were aware. And after day 3, 8 + 8^3 = 8 + 512 = 520 people were aware of the movie.

Therefore, more people got the text about the movie than about the text.

Determine the period of the function g(x) = (cos ;)
Romashka [77]

Answer:

6\pi

Step-by-step explanation:

The period of a sinusoidal function in the form a * cos (b (x + h)) + m is \frac{2\pi }{|b|}. Therefore, we can see that "b" in g(x) is 1/3 and 1/3 substituted into \frac{2\pi }{|b|} is 2\pi/1/3 which is 6\pi.
