foki y^2=-10x

Lösung

foki

y^{2} = - 10 x

Lösung

(- \frac{5}{2}, 0)

Schritte zur Lösung

Rewrite

y^{2} = - 10 x

in the standard form:

4 (- \frac{5}{2}) (x - 0) = (y - 0)^{2}

(h, k) = (0, 0), p = - \frac{5}{2}

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

p

from the center

(0, 0)

along the x-axis

(0 + p, 0)

= (0 + (- \frac{5}{2}), 0)

x^{2} = 8 y

foki (x+6)^2+((y+4)^2)/(1/4)=1

f oc i (x + 6)^{2} + \frac{( y + 4 ) ^{2}}{\frac{1}{4}} = 1

(x^2)/(25)+(y^2)/(16)=1

\frac{x ^{2}}{25} + \frac{y ^{2}}{16} = 1

scheitelpunkte (y^2)/(36)-(x^2)/(64)=1

v er t i ces \frac{y ^{2}}{36} - \frac{x ^{2}}{64} = 1

x^{2} + (y + 2)^{2} = 4
