Each downloaded song costs $1.19. ... Join now. 1 ... Write and solve an inequality to determine how many songs ... This means he can spend less than $10 or exactly $10;
Step-by-step explanation:
Set M = {20,22,24,26,28,30,32,34}
n(M) = no. of elements in set M
i.e.
n(M) = 8
Looks like your function is

Rewrite it as

Recall that for
, we have

If we replace
with
, we get

By the ratio test, the series converges if

Solving for
gives the interval of convergence,

We can confirm that the interval is open by checking for convergence at the endpoints; we'd find that the resulting series diverge.
Circle A would make more sense (I'm not exactly sure) because it shows the entire circle (if you know what I mean).
