The equation of the circle is given as (x-h)² + (y-k)² = r². Then the value of y will be ± √5/3.
<h3>What is an equation of a circle?</h3>
A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at (h, k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
(x-h)² + (y-k)² = r²
The equation of the circle has the center at the origin and the radius is one unit. Then we have
x² + y² = 1
The point P = (-2/3, y) lies on the unit circle. Then the value of y will be
(-2/3)² + y² = 1
y² = 1 - 4/9
y² = 5/9
y = ± √5 / 9

Answer:
Step-by-step explanation:
hello :
450×21/8=1181,25
37/28 or 1and9/28 you have to find the common denominator
Hello there ^ _ ^
2x - 2y + 5z - 2x - y + 3z
The first thing you need to do is to put all the common terms together.
2x - 2x - 2y - y + 5z + 3z
2x - 2x = 0 or nothing so we don't need to put that in the solution
-3y + 8z
The correct option is D
