Answer:
sell stock
Step-by-step explanation:
Taking f(X) to be y
Y = 11 - 3X
3X = 11 - y
X = (11-y)÷3
F^-1(x) = (11 - x)÷3 addING both equations
It gives = 0

Answer:
B. 
Step-by-step explanation:
Cos θ = Adjacent/hypotenuse
Adjacent = 7
Hypotenuse = √(23² + 7²) = √578 = 17√2
Thus:
Cos θ = 
Rationalize
Cos θ = 
Cos θ = 
Cos θ = 
Answer: 6mm
Step-by-step explanation: It is an equilateral triangle so all equal length so 18/3 sides equal to 6mm
