write the equation of a parabola with vertex (-5,8) and directrix x=2. show all of your work and put your equation in graphing/vertex form.

ANSWER

EXPLANATION

The given parabola has vertex at (-5,8).

and directrix at: x=2,

This implies that the axis of symmetry of the parabola is parallel to the x-axis.

This parabola has equation of the form:

where (h,k)=(-5,8) is the vertex.

and p =-5-2=-7

Hence the equation becomes,

The given parabola has vertex at (-5,8).

and directrion at: x=2,

So

axis of symmetry of the parabola is parallel to the x-axis.

This parabola has equation of the form:

(y - k)² = 4p(x - h)(y−k)

where (h,k)=(-5,8) is the vertex.

(y - 8)² = 4p(x -( - 5))(y−8)

and p =-5-2=-7

Hence the equation becomes,

(y - 8)²= 4( - 7)(x + 5)

(y-8)²+28(x+5)=0

is a required equation.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

the answer is 99.
