A parabola can be drawn given a focus of (8, 6) and a directrix of x=4 Write the equation of the parabola in any form.

The equation of the parabola in vertex form is .

Step-by-step explanation:

Since the directrix is of the , then the equation of the parabola in vertex form is of the form:

(1)

Where:

- Dependent variable.

- Independent variable.

- Least distance between focus and directrix.

, - Coordinate of the vertex.

The least distance between focus and directrix is determined by Pythagorean Theorem:

Now, we determine the location of the vertex by the following vectorial formula:

(2)

If we know that and , then the location of the vertex is:

And the equation of the parabola in vertex form is .

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
