• 10.3 Hyperbolas Day TwoRomans 6:4 "Therefore we are buried with him by baptisminto death: that like as Christ was raised up from the dead bythe glory of the Father, even so we also should walk innewness of life."
• 1. Find the equation of the hyperbola in standard form with vertices of ( ± 2, 0 ) and foci ( ± 3, 0 ) .
• 1. Find the equation of the hyperbola in standard form with vertices of ( ± 2, 0 ) and foci ( ± 3, 0 ) . 2 2 2 a=2 c=3 c = a +b 2 9 = 4+b 2 b =5
• 1. Find the equation of the hyperbola in standard form with vertices of ( ± 2, 0 ) and foci ( ± 3, 0 ) . 2 2 2 a=2 c=3 c = a +b 2 9 = 4+b 2 b =5 2 2 x y − =1 4 5
• 2. Find the equation and the foci of the hyperbola with vertices ( 0, ± 4 ) and asymptotes y = ± 4x .
• 2. Find the equation and the foci of the hyperbola with vertices ( 0, ± 4 ) and asymptotes y = ± 4x . a a = 4 and = 4 ∴b = 1 b
• 2. Find the equation and the foci of the hyperbola with vertices ( 0, ± 4 ) and asymptotes y = ± 4x . a a = 4 and = 4 ∴b = 1 b 2 2 2 c = a +b 2 c = 17 c = 17 ≈ 4.1
• 2. Find the equation and the foci of the hyperbola with vertices ( 0, ± 4 ) and asymptotes y = ± 4x . a a = 4 and = 4 ∴b = 1 b 2 2 2 c = a +b 2 c = 17 c = 17 ≈ 4.1 2 y 2 Equation : − x =1 16 foci : ( 0, ± 17 )
