Gre4nikov [31]

Answer:

\frac {(x)^{2}}{8100}+\frac {(y)^{2}}{1900}=1

Step-by-step explanation:

center of the hyperbola  is  (0,0)  = (h, k)

c = the distance form the center to either focal point  = 100

c^{2} =100^{2}=10000

The differences  from the receiver to the transmitters  =  2a

2a =  180  miles

a   =  180/2=90 miles

a^2 =90^{2}= 8100

b^{2}= c^{2} - a^{2}

b^{2}= 100^{2}-90^{2}=1900

b^{2}=1900

The standard form is

\frac {(x-h)^{2}}{a^{2}}+\frac {(y-k)^{2}}{b^{2}}=1

\frac {(x-0)^{2}}{a^{2}}+\frac {(y-0)^{2}}{b^{2}}=1

\frac {(x)^{2}}{8100}+\frac {(y)^{2}}{1900}=1
