Which of the following is a series ? Check all that apply . 1/2 + 1/4 + 1/6 + 1/16 + 3.14159 B. 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 20 2 3k D. 25 - 5 - 10 - 15 - - 125

A Series is always a periodic sum of terms, so only A and D will apply to that definition

(where A= 1/2 + 1/4 + 1/6 + 1/16 + 3.14159 and B=25 - 5 - 10 - 15 - - 125

M=22, hope this helps

Step-by-step explanation:

Set up Graham's altitude function A(m):

A(m) = 14040 - 50m <-- we subtract for descending

Set up Max's altitude function A(m):

A(m) = 12500 + 20m <-- we add for ascending

Set the altitudes equal to each other to solve for m:

14040 - 50m = 12500 + 20m

We type this equation into our search engine to solve for m and we get:

m = 22
