Unformatted text preview: ±ocus: ( √ 10 , 0) Directrix: x = √ 2 ±rom this information, we get c = √ 10 and a e = √ 2. Use this to get that a 2 = √ 20, e = 4 √ 5, b 2 = 10√ 20. Thus, the standard form equation is x 2 √ 20y 2 10√ 20 = 1, and the asymptotes are y = ± r 10√ 20 √ 20 x . Bonus (1 pt): How many di²erent people have been President of the United States? There have been 43 presidents, but Grover Cleveland served nonconsecutive terms (i.e. he was the 22nd and 24th president). Thus, there have only been 42 di²erent presidents. 1...
