foki 20t-t^2

Lösung

foki

20 t - t^{2}

Lösung

(10, \frac{399}{4})

Schritte zur Lösung

Rewrite

y = 20 t - t^{2}

in the standard form

4 (- \frac{1}{4}) (y - 100) = (t - 10)^{2}

(h, k) = (10, 100), p = - \frac{1}{4}

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

p

from the center

(10, 100)

along the y-axis

(10, 100 + p)

= (10, 100 + (- \frac{1}{4}))
