A ruptured pipe in a North Sea oil rig produces a circular oil slick that is y meters thick at a distance x meters from the rupture. Turbulence makes it difficult to directly measure the thickness of the slick at the source (where x = 0), but for x > 0, it is found thaty =0.5(x² + 3x)/x³ + x² + 4xAssuming the oil slick is continuously distributed, howthick would you expect it to be at the source?
