U = sec x ( substitution )
u² + 2 u = 0
u ( u + 2 ) = 0
u = 0, or u = - 2
1/cos x = 0 1/cos x = - 2
(not accepted ) cos x = -1/2
x 1 = 2π/3, x 2 = 4π/3
The answer would be 173.55.
Explanation: it just is
<u>Answer</u>:
equation: y = 24x
Step-by-step explanation:
if y and x is proportional,
y = kx
72 = k * 3
k = 24
→ Here the constant if 24
so the equation that relates x and y :
y = 24x
