Because of its special reflective properties, a
parabola is an ideal shape for collecting
weak radio signals. The European Space
Agency has asked you to write an equation
for the parabolic dish of their new radio
telescope. It is parallel to the ground and
should have the following dimensions:
Width of dish: 60 m
Depth of dish: 10 m
Height above ground level (measured from
the bottom of the dish): 50 m
Horizontal distance from the bottom of the
dish to the control room (the origin): 100 m
