1 dzień temu · In this lesson, we will learn how to find the equation of a circle using its center and a given point or the radius and vice versa.
1 dzień temu · Solution. We begin by writing an equation for the circle centered at the origin with a radius of 5. x2 +y2 = 25. Substituting in the desired x value of 3 gives an equation we can solve for y. 32 +y2 = 25 y2 = 25 − 9 = 16 y = ± 16−−√ = ±4. There are two points on the circle with an x value of 3: (3, 4) and (3, -4).
4 dni temu · The equation of a given circle in general form is x2+ y2 − 8x + 12y + 27 = 0. Write the equation in standard form,(x − h)2 + (y - k)2 = r2, by completing the squares in the equation. Show your work in the table.

2 dni temu · In mathematics, a hyperbola is a type of smooth curve lying in a plane, defined by its geometric properties or by equations for which it is the solution set. A hyperbola has two pieces, called connected components or branches, that are mirror images of each other and resemble two infinite bows.
