The equation of a circle is (x - 4)² + (y - 3)² = 25. What's the center of the circle
A circle is a geometric shape that is a set of points that are all the same distance from a single point. That single point is called the center of the circle, and the line segment that runs from the center of the circle to any point on the edge of the circle is called the radius...
Answer to: Find a Cartesian equation for the curve and identify what type of equation it is (circle, ellipse, line, parabola). r = 9 \tan \theta...
Explanation: An average is the sum of all the numbers in a set, divided by the number of numbers in that set. To figure this one out, set up a simple equation and solve for X: (12 + 19 + X) ÷ 3 = 17 You want to isolate the X, so first multiply both sides by 3. 17×3...
Equation of a circle An equation of a circle represents the cirlce in the algebraic form and it is used for finding the coordinates of the center of the cirlce. (A) The standard form of the equation of a cirlce $$\begin{align} (x-h)^{2}+(y-k)^{2} &= r...
What is the opposite of perpendicular lines? What is the symbol for perpendicular lines? What is the equation for a perpendicular line? Take at home math practice to the next level Empowering parents and educators to make math practice more impactful. Plus, your kids will love it....
A circle is a geometrical shape. It is defined as having a center, and being the set of all points that are a certain fixed distance from that center. (The fixed distance is called the radius of the circle.) The circle is not of much use in algebra since the equation of a circle ...
Thus, the circumference of a circle is a function of the diameter. If x be a symbol to which different numerical values can be assigned, such expressions as x2, 3x, Log. x, and Sin. x, are all functions of x. Function A religious ceremony, esp. one particularly impressive and ...
