The answer is A) √3
cot(-5π/6)=1/tan(-5π/6)
=1/tan(-(5π/6)
Use the property: tan(-x)=-tan(x)
=1/tan(5π/6)
-(1/tan(5π/6))
tan(5π/6)=-√3/3
-(1/-√3/3)
-(1/-√3/3)
=√3
Answer:
من نفی فحمم کی فو چیمه کی روش در این دنیا و آخرت را به
Answer: Qualquer temperatura menor que -3,4°C. Ou seja, -3,5 ; -3,6 ; ...
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Given the inequality 
, we need to solve for "x".
We can subtract 
to both sides:
(This step is shown in the exercise)
Now, we can add 10 to both sides:
(This step is not shown in the exercise)
And finally, divide both sides by -3:
(This is shown in the exercise)
Therefore, the missing step is:
Answer:
i√17 ≈ 4.123106i
Step-by-step explanation:
The square root of a negative number is "i" times the square root of its absolute value. It is an imaginary number.
_____
i is generally the symbol used for √(-1). In some fields, such as electrical engineering, where i has a different meaning, the symbol j may be used instead.
