If P = (-4,-3) and Q = (2, 1) are the endpoints of the diameter of a circle,
find the equation of the circle.
(x - [?])2 + (y - [ ])2 = [
]​

Step-by-step explanation:

To find the centre of the circle, find the mid - point of PQ :

Diameter = 2 x Radius , To Find the diameter, find distance between P and Q:

PQ is the diameter , therefore radius :

Equation of a circle :

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
