Is this the only problem you need help on ? Or is there more ?
Answer:
z^2 = -12y
or y = -(z^2/12)
Step-by-step explanation:
Answer:
z^2 = -12y
Step-by-step explanation:
Given the vertex at origin;
This is same as (0,0)
The focus (0,-3)
The general form is;
(z-h)^2 = 4p(y-k)
(h,k) is the vertex (0,0); so h = 0 and k = 0
The focus is given as;
(h,k + p)
so ;
k + p = -3
but k =0
so p = -3
Thus, the equation of the parabola is;
(z-0)^2 = 4(-3)(y-0)
z^2 = -12y
Log 2 200 = In 200 ã• In 2 = 7.6... â need 8 bits. If a signed number is being stored, then 9 bits would be needed as one as one would be needed to indicate the sign of the number.
8 (assuming unsigned numbers - i.e., you don’t reserve a bit for the sign.
It is 16 because 1/4 multiply 1/4 is 1/16 and 1/16 multiply 16 is 1 .But I may be wrong.
