Answer:
see the attachment for the graph
Step-by-step explanation:
The radius can be computed from the distance formula:
d = √((x2-x1)^2 +(y2-y1)^2)
d = √((7-5)^2 +(2-5)^2) = √(4+9) = √13
d ≈ 3.6056
The radius of the circle is √13, about 3.6056 units.
Answer:
a= m*(4g-h)
Step-by-step explanation:
hope it helps you
Vertex form is basically commplete the square
y=a(x-h)^2+k
y=x^2+14x+4
take 1/2 of 14 and square it, (7^2=49)
add that and its negative to right side
y=x^2+14x+49-49+4
factor perfect squaer
y=(x+7)^2-49+4
y=(x+7)^2-45
answer is A
Just subsitute 8 for n
1/2(8)^2-1/2(8)
1/2(64)-4
32-4
28
D
