Which equation has a graph that is a parabola with a vertex at (-2,0)

Step-by-step explanation:

Given the vertex of parabola at (-2,0).

We know that equation of parabola along x- axis when vertex  at (h,k)

Given vertex (-2,0)

h= -2 and k=0

It means parabola along x- axis and passing through the point (-2,0).

The vertex of parabola is the highest or lowest point

Or

The vertex of parabola is the point of maximum or minimum.

The vertex is the point of where parabola intersect the axis.

We are given vertex (-2,0)

It means parabola intersect the x- axis at point (-2,0).

Put the value of vertex in the equation of parabola when its axis parallel to  x- axis

Equation of parabola

Put h=-2 and k=0 in the equation of parabola

Then we get the equation of parabola

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
