(x+23/5)^2+(y-2/5)^2=(sqrt(373))/5

解

(x + \frac{23}{5})^{2} + (y - \frac{2}{5})^{2} = \frac{373}{5}

(a, b) = (- \frac{23}{5}, \frac{2}{5}), r = \frac{373}{5}

解答ステップ

(x + \frac{23}{5})^{2} + (y - \frac{2}{5})^{2} = \frac{373}{5}

(x + \frac{23}{5})^{2} + (y - \frac{2}{5})^{2} = \frac{373}{5}

を標準的な円のequationの形式で書き換える

(x - (- \frac{23}{5}))^{2} + (y - \frac{2}{5})^{2} = \frac{373}{5}^{2}

ゆえに円の特性は:

(a, b) = (- \frac{23}{5}, \frac{2}{5}), r = \frac{373}{5}
