Answer:

28.28

Step-by-step explanation:

Using Pythagoras' identity on the right triangle

d² = 20² + 20² ← Pythagoras' identity

    = 400 + 400 = 800 ( take the square root of both sides )

d = \sqrt{800} ≈ 28.28 ( to 2 dec. places )

Find an equation of the circle that satisfies the given conditions. (Use the variables x and y.)
prohojiy [21]

Answer:

x^2 + y^2 = 52

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, (x_1,y_1) and (x_2,y_2). The distance between them is given by:

D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Equation of a circle:

The equation of a circle with center (x_0,y_0) and radius r has the following format:

(x - x_0)^2 + (y - y_0)^2 = r^2

Center at the origin;

This means that x_0 = 0, y_0 = 0

So

(x - x_0)^2 + (y - y_0)^2 = r^2

(x - 0)^2 + (y - 0)^2 = r^2

x^2 + y^2 = r^2

Passes through (4, 6)

The radius is the distance from this point to the center. So

r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

r = \sqrt{(4-0)^2+(6-0)^2}

r = \sqrt{16+36}

r = \sqrt{52}

So

r^2 = 52

Then

x^2 + y^2 = r^2

x^2 + y^2 = 52
