A mariner is using a GPS, or global positioning system, to create a nautical chart that documents underwater objects and hazards. The mariner has found three hazards positioned in a circular pattern at points D(7,1), E(14,−4), and F(2,−6). If EF⎯⎯⎯⎯⎯ is a diameter of the circle, what is the equation of the circle that contains the three hazards? Write your answer in standard form.

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).

Over the course of the school year, you keep track of how much snow falls on a given day and whether it was a snow day. your data indicates that of twenty-one days with less than three inches of snow, five were snow days, while of the eight days with more than three inches of snow, six were snow days. if all you know about a day is that it is snowing, what is the probability that it will be a snow day?

What is the value of p in the equation y^ = -4x?
