Answer:
D is halved
Step-by-step explanation:
Given :
If n is doubled :
- D' = -dv/60(2n)
- D' = -dv/120n
- D' = D/2
When n is doubled, D (<u>the drop factor</u>) is half of its original value.
Answer:
(x-5)^2 + (y+9)^2 = 144
Step-by-step explanation:
The equation of a circle can be written as
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x-5)^2 + (y- -9)^2 = 12^2
(x-5)^2 + (y+9)^2 = 12^2
(x-5)^2 + (y+9)^2 = 144
