Question

g A satellite dish has the shape of a parabola when viewed from the side. The dish is 56 inches wide and 49 inches deep. How far is the receiver from the bottom of the dish if the receiver is placed at the focus?

Answer 1

Answer:

The receiver placed at the focus is 56.43 from the bottom of the dish

Explanation:

Let the receiver be R

The satellite dish is 56 and at the focus is 28

49 is the depht

We can get R using the Pitagoras Theorem

a² + b² = R²

28² + 49² = R²

Do calculations

784 + 2401= R²

3185 = R²

R= √3185

R= 56.4358
