Find the center of the circle whose equation is (x-2)^2(y-4)^2=9.

guajiro [1.7K]

Answer:

B.(2,4)

Step-by-step explanation:

The equation for a circle is written as

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

where (h,k) is the center and r is the radius

(x-2)^2+(y-4)^2=9.

Rewriting this equation

(x-2)^2+(y-4)^2=3^2

The center is at (2,4)

If BA [a= (-2,-3) b= (1,2)] is extended all the way through A creating a BF and A becomes the midpoint of BF, then what are the

Irina18 [472]

Answer:

(-5,-8)

Step-by-step explanation:

If M(x,y) is the midpoint of the segment CD, where $C(x_1,y_1),\ D(x_2,y_2),$ then

$x=\dfrac{x_1+x_2}{2}\\ \\y=\dfrac{y_1+y_2}{2}$

You are given two points A(-2,-3) and B(1,2), let point F be the point with coordinates (x,y). Yuo know, that point A is the midpoint of BF, then

$x_A=\dfrac{x_B+x_F}{2}\\ \\y_A=\dfrac{y_B+y_F}{2}$

Substitute known coordinates:

$-2=\dfrac{1+x}{2}\Rightarrow 1+x=-4,\ \ x=-5\\ \\-3=\dfrac{2+y}{2}\Rightarrow 2+y=-6,\ \ y=-8$

So, point F has coordinates (-5,-8)
