The function f(x)=−x2−7x+30 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diving board. What is a zero of f(x), and what does it represent? A) x = 10; the diver hits the water 10 feet away horizontally from the board. B) x = 3; the diver hits the water 3 feet away horizontally from the board. C) x = 10; the diver jumps in the pool at 10 feet per second. D) x = 3; the diver jumps in the pool at 3 feet per second.

In 2015, a large group of female walruses and their calves convened on a single beach in Alaska. Traditionally, walruses utilized sea ice as a resting and nursing ground for their young. However, due to anthropogenic activities and global warming, significant portions of the sea ice have melted. This situation could have several consequences for the walruses and their ecosystem over time. Firstly, the overcrowding on beaches can lead to increased mortality rates among calves due to stampedes when the walruses are startled. This could potentially result in a decline in the walrus population. Secondly, without sea ice, walruses are forced to swim longer distances to find food, which can be particularly strenuous for the young, possibly leading to starvation and reduced survival rates. Thirdly, the benthic habitats—the sea floor ecosystems—could be adversely affected due to the increased pressure from more walruses foraging in a concentrated area. This could lead to the depletion of food resources, affecting not only the walruses but also other species that rely on the same food sources. Lastly, there could be broader ecological impacts as the balance between predators and prey shifts. Other arctic animals that depend on sea ice for their life cycles may also be forced to alter their behaviors, potentially disrupting the entire marine food web.
