Question

Help please explain!
write standard equation for a circle endpoints of diameter at (-4,-2) and (8,4).

Answer 1

find the distance and midpoint associated with the points

Answer 2

given points A,B ... midpoint is (A+B)/2

distance is sqrt(A-B)^2 perse

Answer 3

(8, 4)
(-4,-2)
--------
4 , 2 : /2 midpoint is 2,1


(8, 4)
- (-4,-2)
---------
12, 6 ; sqrt(12^2+6^2) is the diameter; half it for a radius

Answer 4

for a center (h,k) and a radius (r): the equation of a circle is defined as\[(x-h)^2+(y-k)^2=r^2\]

Answer 5

okay thanks a bunch!!

Answer 6

good luck
