The coordinates of point D is (0, 7)
<h3><u>solution:</u></h3>The midpoint M of CD has coordinates (2, 5)
Point C has coordinates (4, 3)
To find: coordinates of point D
The midpoint of line AB conatining points and
is given as:
Here in this problem,
Midpoint (C, D) = (2, 5)
Subsituting the values in formula we get,
On comparing both the sides we get,
Thus the coordinates of point D is (0, 7)
Answer:
Step-by-step explanation:
y=a(x-h)^2+k
-12=a(1-h)^2+k
16=a(3-h)^2+k
subtract
a(3-h)^2-a(1-h)^2=28
a[(3-h)^2-(1-h)^2]=28
a=2
2[(3-h)^2-(1-h)^2]=28
(3-h)^2-(1-h)^2=14
9+h^2-6h-(1+h^2-2h)=14
9+h^2-6h-1-h^2+2h=14
-4h+8=14
-4h=6
h=-3/2
16=2(3+3/2)^2+k
16=2×81/4+k
k=16-81/2=-49/2
so y=2(x+3/2)²-49/2
