Which points are 4 units apart?

xz_007 [3.2K]

The points that are 4 units apart are B and D

<h3>Complete question</h3>

Which points are 4 units apart? On a coordinate plane, point A is at (-2, 4), point B is at (3, -6), point C is at (-1, 0), point D is at (3, -2).

B and C

C and D

A and C

B and D

<h3>How to determine the points?</h3>

To do this, we simply calculate the distance using the following equation

$d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2$

Using the given points, we have:

$BC = \sqrt{(3+ 1)^2 + (-6 -0)^2} = 7.2$

$CD = \sqrt{(-1 - 3)^2 + (0 +2)^2} = 4.5$

$AC = \sqrt{(-2 + 1)^2 + (4 -0)^2} = 4.1$

$BD = \sqrt{(3 - 3)^2 + (-6 +2)^2} = 4$

Hence, the points that are 4 units apart are B and D

A circle passes through point (-2, -1) and its center is at (2, -1). Which equation represents the circle?

Anastaziya [24]

Answer:

$\text{A)}\qquad (x-2)^2+(y+1)^2=16$

Step-by-step explanation:

The formula for a circle of radius r centered at (h, k) is ...

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

Both of the given points are on the line y=-1. The distance between them is the difference of their x-coordinates, 2 -(-2) = 4. So, the radius of the circle is 4 and the equation becomes ...

(x -2)^2 +(y -(-1))^2 = 4^2

(x -2)^2 +(y +1)^2 = 16 . . . . . . . . . matches choice A
