((x-0.31))/(1.9)+(y^2)/(4.09)=2

解

\frac{( x - 0.31 )}{1.9} + \frac{y ^{2}}{4.09} = 2

(h, k) = (4.11, 0), p = - 0.53815 \dots

解答ステップ

\frac{x - 0.31}{1.9} + \frac{y ^{2}}{4.09} = 2

\frac{x - 0.31}{1.9} + \frac{y ^{2}}{4.09} = 2

を標準的な形式で書き換える:

4 (- 0.53815 \dots) (x - 4.11) = (y - 0)^{2}

ゆえに放物線の特性は:

(h, k) = (4.11, 0), p = - 0.53815 \dots
