write the equation in standard form for the hyperbola with vertices ( – 12,0) and (12,0), and foci ( – 13,0) and (13,0).

Mashcka [7]

Standard form for the hyperbola with vertices ( – 12,0) and (12,0), and foci ( – 13,0) and (13,0) is $\frac{x^{2} }{144}-\frac{y^{2} }{25}=1$

Hyperbola is a plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant.

Given,

The Vertices of the hyperbola = (-12,0) and (12,0)

Foci = (-13,0) and (13,0)

a=12

ac=13

c= $\frac{13}{12}$

We know,

c= $\sqrt{1+\frac{b^{2} }{a^{2} } }$

$c^{2}=1+\frac{b^{2} }{a^{2} } \\(\frac{13}{12} )^{2}=1+\frac{b^{2} }{144} \\\frac{169}{144}=1+ \frac{b^{2} }{144} \\\frac{b^{2} }{144} =\frac{25}{144}\\ b^{2}=25$

The equation of the hyperbola is

$\frac{x^{2} }{a^{2} }-\frac{y^{2} }{b^{2} }=1\\ \frac{x^{2} }{144 }-\frac{y^{2} }{25 }=1$

Hence, the standard form for the hyperbola with vertices ( – 12,0) and (12,0), and foci ( – 13,0) and (13,0) is $\frac{x^{2} }{144}-\frac{y^{2} }{25}=1$

Andy found these three ordered pairs for the equation y = 65x +250: (0, 250), (5,575), and (10,900). He graphed the ordered pair

Leni [432]

The range is the y values for the given x-values (domain). Here the graph runs from y = 250 to y = 900. Therefore the range is {y | 250 <= y <= 900}.
