A satellite dish has cross-sections shaped like parabolas. The receiver is located 13 inches from the base along the axis of sym
horsena [70]

Answer:

Depth = 3.3 inches

Step-by-step explanation:

 Given that the shape of the satellite looks like a parabola

The equation of parabola is given as follows

x^2=4\times a\times y

Where

a= 13

Therefore

x^2=4\times 13\times y

x^2=52\times y

Lets take (13 , y) is a

Now by putting the values in the above equation we get

13^2=52\times y

y=\dfrac{13^2}{52}=3.25

y=3.25 in

Therefore the depth of the satellite at the nearest integer will be 3.3 inches.

Depth = 3.3 inches
