A community skating rink is in the shape of a rectangle with semicircles attached at the ends. the length of the rectangle is 20 feet less than twice the width. the thickness of the ice is 1/16 of a foot.
Write the volume equation V, as a function of the width X.
Please Help...
I have like two crappy speakers from a broken Sony boombox and i want to bolt them onto the bike rack of my Schwinn. I hooked up end of speaker wire to a headphone jack and tried out Ipod but volume is way low. I know i need an Amp for power and a small battery, would i need anything else?
