1. A comet's path (as it approaches the sun) can be modeled by one branch of hyperbola 1600 = 1 where the sun is at the focus of that part of hyperbola. Each unit of the coordinate system 39204 represent 1 million miles. Find the coordinates of the sun (assuming it is at the focus with non- negative coordinates). How close does the comet come to the sun? 2. The towers of a bridge connecting two cities are 2560 meters apart and rise 320 meters above the road. The cable between the towers has the shape of a parabola and the cable just touches the side of the road midway between the towers. What is the height of the cable 400 meters from a tower? Round to the nearest meter.

Question

solve the following problems involving conic sections.

(please make the solutions easier to understand and study)

1.
A comet's path (as it approaches the sun) can be modeled by one branch of hyperbola
1600
= 1 where the sun is at the focus of that part of hyperbola. Each unit of the coordinate system
%3D
39204
represent 1 million miles. Find the coordinates of the sun (assuming it is at the focus with non-
negative coordinates). How close does the comet come to the sun?
2.
The towers of a bridge connecting two cities are 2560 meters apart and rise 320 meters above
the road. The cable between the towers has the shape of a parabola and the cable just touches the
side of the road midway between the towers. What is the height of the cable 400 meters from a
tower? Round to the nearest meter.
