Your task is to design a curved arch similar to the a tunnel for cars. with a horizontal span of 100 m and a maximum height of 20 m.(adsbygoogle = window.adsbygoogle || []).push({});

Using a domain of {x:-50<=x<=50} and {y:0<=y<=20} determine the following types of equations that could be used to model the curved arch.

the equation of a hyperbola in the form [tex] \frac {(x-h)^2} {a^2} - \frac {(y-k)^2} {b^2} = -1 [/tex] where b=10 and the lower arm of the hyperbola would represent the arch.

How do i find a and the center (h,k) please help me I am struggling on this question.
