The height h above the roadway of the main cable of the Golden Gate Bridge can be modeled by the function h(x) = 1/9000x^2-7/15x+500, where x is the distance in feet from the left tower.

a. Complete the square, and write the function in vertex form.

b. What is the vertex, and what does it represent?

c. The left and right towers have the same height. What is the distance between them?

Aquality characteristic of new iphone x made at the amsterdam plant at apple computers has a manufacturing specification (in mm) of 0.200 +/- .07. historical data indicates that if the quality characteristic takes on values greater than 0.27 or smaller than 0.13 the component fails at a cost of20.19. based on these data: determine the taguchi loss function (must show work) calculate an estimated loss for a quality characteristic of .30 calculate an estimated loss for quality characteristic of .40.
