Battery dying and fans blowing every ten minutes

my battery on macbook pro dying pretty recently. im not sure if i'm doing on computer or if battery going bad.
problem have been having fans blowing on heating. again i'm not sure if i'm doing happened couple months ago , stopped awhile.

have on why doing this? i'm poor college student , enrolled in art school if computer dies ill in trouble.

 

launch activity monitor , change "my processes" @ top "all processes", click on cpu column heading once or twice, arrow points downward (highest values on top). see may consuming system resources, account high heat , quick battery drain.

should answer most, if not all, of battery questions:
