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 :
 , 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:
Acute
Step-by-step explanation:
This should be an acute triangle because if this was a right angle, then the three sides should be figured out by the Pythagorean Theorem.
An obtuse angle wouldn't be right either, you need an angle to be over 90.
 
        
             
        
        
        
7.32
10 = 73.2
100 = 732
1000 = 7320
0.006
10 = 0.06
100 = 0.6
1000 = 6
The decimal place moves to the right depending on how many zeros the number has. 
For example, if you had 0.6 multiplied by 100, you would move 2 decimal places to the right because 100 has two zeros.
 
        
             
        
        
        
1_ 210+90= 300
2_ it's prime:
[1,19]
good luck
