leitkurve-5t^2+20t

Lösung

leitkurve

- 5 t^{2} + 20 t

Lösung

y = \frac{401}{20}

Schritte zur Lösung

Rewrite

y = - 5 t^{2} + 20 t

in the standard form

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

(h, k) = (2, 20), p = - \frac{1}{20}

Parabola is symmetric around the y-axis and so the directrix is a line parallel to the x-axis, a distance

- p

from the center

(2, 20)

y-coordinate

y = 20 - p

y = 20 - (- \frac{1}{20})

Fasse zusammen

y = \frac{401}{20}
