General Equation of a Conic:
(a) Determine the Type of Conic
I figured out that its a hyperbola: ac - b2 =
(-1/4)
(b) Determine if the Conic is Degenerate
I figured out that its not degenerate: acf + 2bde -
ae2 - b2f - cd2 = 1
(c) Sketch a graph of the Conic without using a graphing
calculator

ch3ch2oNa is weak?) and a strong nuc (is it also a strong nuc?
confused) means an SN2 reaction. However, Ethanol is a polar protic
solvent, and I thought SN2 reactions require APROTIC??? How is this
possible?
