Which equation represents a circle with a center at (2, –8) and a radius of 11?

Answers

Answer 1
Answer:

(x-h)^2 +(y-k)^2 = r^2 is the equation for a circle centered at (h,k) and radius r

(x-2)^2 +(y- (-8))^2 = 11^2

(x-2)^2 +(y+8)^2 = 11^2

Answer:(x-2)^2 +(y+8)^2 = 11^2
Answer 2
Answer:

Answer:

(x-2)^2 + (y+8)^2 = 11^2

Step-by-step explanation:

The standard equation of a circle with center at (h,k) and radius r is

(x-h)^2 + (y-k)^2 = r^2.

Filling in the given info, we get:  

(x-2)^2 + (y+8)^2 = 11^2

The midpoint of AB is M (2,0). If the coordinates of A are (7, -2), whatare the coordinates of B?

Answers

Answer:

The coordinates of point B are (-3,2)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

M((x_1+x_2)/(2),(y_1+y_2)/(2))

we have

M(2,0)\n(x_1,y_1)=(7,-2)

substitute

(2,0)=((7+x_2)/(2),(-2+y_2)/(2))

Find the value of x_2

we have that

2=(7+x2)/(2)

4=7+x_2\nx_2=-3

Find the value of y_2

we have that

0=(-2+y_2)/(2)

0=-2+y_2\ny_2=2

therefore

The coordinates of point B are (-3,2)
