What is the equation of the line that passes through the points (–p, –q) and (p, q)?

Effectus [21]

slope (y2-y1)/(x2-x1)

m = (q--q)(p--p)

m = 2q/2p

m=q/p

point slope form

y-y1=m(x-x1)

y-q =q/p(x-p)

distribute

y-q=q/p *x -q

add q to each side

y = q/p *x

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
