The coordinate of D is (1,1).

Step-by-step explanation:

Given,

The coordinates of the square are A(1,5), B(5,5), C(5,1)

To find the the coordinate of D

Formula

We know that the diagonals of a square bisects each other.

And mid point of any two coordinates (x_{1} ,y_{1} ) and (x_{2} ,y_{2} ) will be  \frac{x_{1}+x_{2}  }{2} ,\frac{y_{1}+y_{2}  }{2})

Let,

O be the mid point of diagonal AC

So, coordinates of O is (\frac{1+5}{2} ,\frac{5+1}{2} ) = (3,3)

Hence, O is also the mid point of diagonal BD.

Let, coordinates of D is (x,y)

According to the formula

\frac{5+x}{2} = 3 and \frac{y+5}{2} = 3

or, 5+x = 6 and y+5 = 6

or, x=1 and y=1

So,

The coordinate of D is (1,1).

General form of the equation of a circle with its center at (-2, 1) and passing through (-4, 1)
jonny [76]

 

hello :<span>
<span>an equation of the circle Center at the A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -2 and b = 1 (Center at the A(-2,1))
r = AP......P( -4 , 1)
r² = (AP)²
r² = (4+2)² +(1-1)² = 36
an equation of the circle that satisfies the stated conditions.
Center at </span></span> A(-2,1), passing through P(-4, 1) is : (x+2)² +(y-1)² = 36
