All right. I need help!! :) Understanding the problem.
A comet’s path (as it approaches the sun) can be modeled by one branch of the hyperbola , where the sun is at the focus of that part of the hyperbola. Each unit of the coordinate system is 1 million miles.
Find the coordinates of the sun (assuming it is at the focus with non-negative coordinates). Round to the nearest hundredth.
How close does the comet come to the sun?
