Final answer:
It is true that a satellite dish is shaped like a paraboloid as this allows it to effectively focus weak signals from satellites in orbit to a single point for reception.
Step-by-step explanation:
A satellite dish is indeed the shape of a paraboloid. This statement is true. The shape of a satellite dish is designed to be a paraboloid because it has the property that all incoming signals, which parallel to the axis of symmetry, are reflected and focused to a single point, known as the focal point. This is where the signal receiver of the dish is placed. The design ensures that even weak TV signals sent from satellites in orbit can be received effectively. This principle is similar to how a parabolic mirror works in a car headlight, where the light at the focal point is projected outwards in parallel beams.
