Note the speed of sound s is approximately 1100 to 1200 feet per second. Just count the number of seconds that pass between a flash of lightning and the crack of thunder that follows it then. Many of us have heard that if you determine the lightning distance from you to a strike by counting the number of seconds between hearing thunder and seeing a lightning strike that is how far away in miles the lightning is not true.
In algebra a quadratic equation from the Latin quadratus for square is any equation that can be rearranged in standard form as ax²bxc0 where x represents an unknown and a b and c represent known numbers where a 0.
