Question 1161282: The height of a telephone line is given by the equation
h=x^2/7 +55, where h is the height of the telephone line and x is the
distance from the lowest part of the line to a telephone pole. If the
line hooks onto the pole at a height of 250 feet, what is the distance
between the two poles? Give answer to the nearest hundredth.

 + 55 = 250


 = 250 - 55 = 195

 = 195*7 = 1365

x =  = 36.946.


It is half of the distance between the poles;  

so the whole distance between poles is 2*36.946 = 73.89 feet (rounded as requested).    ANSWER

Solved.
