Answer:

Step-by-step explanation:
Give that:
the surface equation is 
from the family of traces in x = n given that
, the equation can be represented as :


This represents a family of hyperbola for all values of n expects that n = ± 1
So, if n = ± 1,
Then

(y-z) (y+z) = 0
y = ± z
So, for n = ± 1, it is a pair of line for y = z, y = -z
Answer:
0.2
Step-by-step explanation:
y^t=3^2=9
x/y^t=2/9=0.2
Answer:
That would be 19.6875 in decimal form.
