Three values of x that would result in y = cot x being undefined are 
Given :
y=cot(x)
we need to find where cot(x) is undefined
We know that 
when the denominator is 0 then we can say cot(x) is undefined
Lets find out x values that makes sin(x) as 0
We know that sin(0)=0

x values values that makes sin(x)=0 are 
These x values makes the denominator of cot(x) as 0 and it is undefined
So , three values of x that would result in y = cot x being undefined are

Answer: Their combined age will be 90.
2x+x=54 will allow you to find their ages. Solve for x ( this is Timothy's age) and you get 18. Times 2 is 36 for Paul's age. Finally, Timothy will be 36 in 18 years and in 18 years Paul will be 54. Add their ages together and you get 90.
Answer:

capacity of truck = 1000 gallons
total number of trips = 3000/1000 = 3
total oil to reach the destination = 3000-3000=0
I hope this helps.
Answer:
Trinomial.
Step-by-step explanation:
Note how much terms there are in the given expressions:
Term 1: 
Term 2: 
Term 3: 
Note each meaning of the terms:
Monomial: Having only one term.
Binomial: Having two terms.
Trinomial: Having three terms.
Polynomial: Typically used to describe expressions with 4 or more terms.
In this case, there are only 3 terms, and so your answer is Trinomial.
