foki 40x-5x^2

Lösung

foki

40 x - 5 x^{2}

Lösung

(4, \frac{1599}{20})

Schritte zur Lösung

Rewrite

y = 40 x - 5 x^{2}

in the standard form

4 (- \frac{1}{20}) (y - 80) = (x - 4)^{2}

(h, k) = (4, 80), p = - \frac{1}{20}

Parabola is symmetric around the y-axis and so the focus lies a distance

p

from the center

(4, 80)

along the y-axis

(4, 80 + p)

= (4, 80 + (- \frac{1}{20}))
