A circle in the xy-plane is centered at (3, 0) and has a radius with endpoint (1, 8/3 ). Which answer choice is an equation of t
gayaneshka [121]

Answer: (x - 3)² + y² = \frac{100}{9}

<u>Step-by-step explanation:</u>

Circle Formula: (x - h)² + (y - k)² = r²  ; (h, k) is the center & r is the radius

Use the distance formula for (3, 0) and (1, \frac{8}{3})

r = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

r = \sqrt{(3-1)^{2}+(0-\frac{8}{3})^{2}}

r = \sqrt{(2)^{2}+(-\frac{8}{3})^{2}}

r = \sqrt{4+\frac{64}{9}}

r = \sqrt{\frac{36}{9}+\frac{64}{9}}

r = \sqrt{\frac{100}{9}}

r = \frac{10}{3}

****************************************************

Center (h, k) = (3, 0)   Radius (r) = \frac{10}{3}

(x - h)² + (y - k)² = r²

(x - 3)² + (y - 0)² = (\frac{10}{3})²

(x - 3)² + y² = \frac{100}{9}

• How do you use the distance formula and slope formula to prove properties of polygons?
patriot [66]

Answer:

distance formula= \sqrt{x} (x_{2} -x_{1} )^{2} + (y_{2} -y_{1} )^{2} = find the length(units) using coordinates.

slope formula= m=\frac{rise}{run} =\frac{y_{2}-y_{1}  }{x_{2} -x_{1} }= determines slope of a line using two points on the line(coordinates)

When working with polygons the main properties which are important are:

The number of sides of the shape.

The angles between the sides of the shape.

The length of the sides of the shape.

length , width

straight lines , angles, vertices, vertex

A polygon is any 2-dimensional shape formed with straight lines.

a plane figure with at least three straight sides and angles, and typically five or more.

Step-by-step explanation:

<h2><u>answer= use distance and slope to determine that opposite side of a polygon are the same length and same slope</u></h2>
