Write the equation for a parabola with a focus at (2, 2) and a directrix at x = 8.

Bond [772]

Let P(x,y) be a point on the parabola. The definition of a parabola is the squared distance from P to focus F(2,2) equals the squared distance to the directrix x=8.

squared distance from P(x,y) to focus F(2,2)

(x - 2)² + (y - 2)²

squared distance from P(x,y) to the directrix x=8.

(x-8)²

Those are equal in a parabola,

(x - 2)² + (y - 2)² = (x-8)²

x² - 4x + 4 + y² - 4y + 4 = x² - 16x + 64

y² - 4y - 46 = -12x

That's a sideways parabola,

x = -(y² - 4y - 46)/12

An 11-m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 14 m. Find the lengt

Arte-miy333 [17]

Answer:

8.66 m

Step-by-step explanation:

Given that,

The distance from the top of the building to the tip of the shadow is 14 m

The height of the building is 11 m.

We need to find the length of the shadow. we can see that the length of the shadow forms the base of the triangle.

The distance from the top of the building to the tip of the shadow form hypotensue and height of the building forms perpendicular. So, we can use Pythagoras theorem to find the base.

So,

$H^2=b^2+h^2\\\\b^2=H^2-h^2\\\\b=\sqrt{14^{2}-11^{2}}\\\\b=8.66\ m$

So, the length of the shadow is 8.66 m.
