Which is the equation of the parabola that opens to the right, has a focus at (3.0), and
has a directrix at x=-3?

The equation of the parabola will be:

Step-by-step explanation:

The vertex  (h, k)  is halfway between the directrix and focus.

Find the  x  coordinate of the vertex using the formula

x = (x-coordinate of focus + directrix)/2

 = (3-3)/2

 = 0/2

 =0

The  y -coordinate will be the same as the y-coordinate of the focus.

so the vertex will be: (0, 0)

Finding the distance from the focus to the vertex

The distance from the focus to the vertex and from the vertex to the directrix is |p|.

Subtract the  x  coordinate of the vertex from the x -coordinate of the focus to find  p .

Substitute in the known values for the variables into the equation

Therefore, the equation of the parabola will be:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
