A circle has the equation (x−4)2+(y−1)2=34.
What are the coordinates of the center and the length of the radius?

The center is at (4,1), and the radius is 34−−√ units.

The center is at (4,1), and the radius is 34 units.

The center is at (1,4), and the radius is 34 units.

The center is at (1,4), and the radius is 34−−√ units.

A

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 4)² + (y - 1)² = 34 ← is in standard form

with centre = (4, 1 ) and r² = 34 ⇒ r = → A

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
