Answer:
65.17°
Step-by-step explanation:
→ Inverse cosine -0.42
65.17°
→ As the domain is between 0 and 360, any negative values can be ignored
The answer is: D. -1/3 !! hope that helps
Answer:
We can find the sum of all the coefficients by substituting all the variables in the expansion with one.
a. u=1,v=1
sum==
b.u=1,v=1
sum==1
c.u=1,v=1
sum==-1
d.u=1,v=1
sum==-
e.i=1
sum==
f.i=1
sum==0
g.i=1
sum==
h.i=1
sum==
Match of the equation with the verbal description of the surface would be :
Equation 1 = C. plane
Equation 2 = F. Circular cylinder
Equation 3 = C. plane
Equation 4 = E. sphere
Equation 5 = A. cone
Equation 6 = E. Sphere
Equation 7 = F. Circular cylinder
Equation 8 = B. Eliptic or circular paraboloid
Equation 9 = A. cone
Hope this helps
