## Which is the standard equation for a circle centered at the origin with radius r answers com?

The standard form for the equation of a circle with radius r , center at (h, k) is given as (x – h)2 + (y – k)2 = r2. Since the origin is given as the center, h and k are both equal to zero.

## Which is the standard equation for a circle centered at the origin with radius R apex?

x2 + y2 = r2. This is the equation of a circle with center at the origin and radius r.

## Which of the following is the equation for a circle with a radius of R and center at H K?

The equation of a circle with center (h,k) and radius r units is (x−h)2+(y−k)2=r2 .

## Which of the following is the equation for a circle with a radius of r?

We know that the general equation for a circle is ( x – h )^2 + ( y – k )^2 = r^2, where ( h, k ) is the center and r is the radius.

## Which of the following is the equation for a circle with a radius of RAND Center?

(x – h)^2 + (y – v)^2 = r^2. The answer would be C.

## What is the equation of the circle with center 0 0 that passes through the point (- 8 3?

The equation of the circle is x^2 + y^2 = 25 Given that the center of the circle is the point (0,0).

## Which equation represents a circle with a center?

In the diagram, a circle centered at the origin, a right triangle, and the Pythagorean theorem are used to derive the equation of a circle, x2 + y2 = r2.

## Which of the following is the equation for a circle with a radius of R and center at HV?

Answer: (x – h)² + (y – v)² = r². Step-by-step explanation: Given : A circle with a radius of r and center at (h,v).

## What is an equation of a circle with its center at 3 and a radius of 4?

1 Answer. The equation of the circle with center (−3,−4) and radius 3,in standard form, is: (x+3)2+(y+4)2 = 9.

## When you move a circle vertically?

Yes, if you move a circle vertically, the y-coordinate of the center changes.

## Which of the equations below could be the equation of this parabola 1 4?

Answer: Option D. x = (1/4)y². Parabola defined by this equation has the axis of symmetry parallel to the x axis and opening at right of the x axis.

## What is the name of the line that you use to define a parabola?

A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola, and the line is called the directrix .

## What is the extreme point on a parabola?

One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function.

## Which of the following has the steepest graph?

Answer: Option D. is the correct option. Step-by-step explanation: Since all the given graphs are of a straight line therefore the graph which will have the maximum slope will be the steepest.
