Suppose sigma ∞ to n=1 of (an) converges absolutely. Define (pn) = max(0, (an)) and (qn) = min(0, (an)).
Then both sigma ∞ to n=1 of (pn) and sigma ∞ to n=1 of (qn) converge.

Step-by-step explanation:

The steps are in the (2) pictures below.

can you make your screen more see able?

then i might be able to .

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
