You are to design a road for a high mountain pass. there are two routes over the pass, but both have to cross steep ravines. use what you know about solving radical functions to design a bridge that will safely cross the ravine. 1. what is the horizontal distance that your bridge must span to clear the ravine? 100 feet 2. write a function that models the relationships among x, y, and r. (hint: use the pythagorean theorem.) then solve the equation for r in terms of x and y. 3. there are several possible heights at which the higher end of the bridge can be attached to the higher mountain. fill in the table below to use 5 possible values for y, and calculate the resulting values for r.
