What is the complex number of z 2 - Ii?
The complex number of the equation z = x + iy is x.
What are complex root?
The complex roots of an equation are the complex numbers that are solutions to the equation.
In the standard equation for a circle centered at any point a horizontal movement of the circle results in a change in which number?
the number that is part of the x-term
When you make the circle bigger or smaller which number of the standard equation for a circle centered at the origin changes?
Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9
How is solving a quadratic equation with complex numbers like solving a quadratic equation with real numbers?
Because of how close the two are. The only difference between the two is that a complex number is any whole number along side of a fraction, while a real number is any positive number.
What number changes in the equation for a circle when you move the circle horizontally?
the number that is the x-coordinate
What is the complex number of z 2 - Ii?
The complex number of the equation z = x + iy is x.
What is an algebraic number?
An algebraic number is a complex number which is the root of a polynomial equation with rational coefficients.
When you make the circle smaller which number in the standard equation for a circle centered at the origin decreases?
The radius of the circle decreases when you make the circle smaller.

What equation Describes the circle With the radius 9?
(x2 + any number) + (y2 + any number) = 81

The equation of the inner circle is x2 plus y2 equals 4 the radius of the outer circle is four times the radius of the inner circle write the equation of the outer circle?
The inner circle is x2 + y2 = 4. The radius of the inner circle is the square root of 4, which is 2. To find the radius of the outer circle, multiply 2 times 4. The radius of the outer circle is 8. Square 8 (82 or 8 x 8) to find the number to put into the equation of the outer circle. This is 64. The equation for the outer circle is x2 + y2 = 64.
What is the solution set of an equation of a circle?
The solution set is all points on the circle.
