Use desmos graphing calculator
Answer:
a = -2 z^-3 c^6
Step-by-step explanation:
equations are given as
a = 2b^3 .....1 and
b = -1/ z c^-2 .....2
put the value of b in eq 1
a = 2(-1/z c^-2)^3
a = 2(-1/z^3 c^-6)
or a = -2 z^-3 c^6
Answer:
C
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosθ = 
= 
, then
θ = 
( ) ≈ 64° ( to the nearest degree )
