Our x equals 0 so the answer is 0
Greater because a centimeter is smaller than an inch.
People per hour because the dependent quantity is the hours.
The number of people that enter depends on the number of hours the park is open
We have to find the domain of y = cotx
We know that cotx = cos
x / sinx
And also when sinx becomes zero cotx becomes undefined
And again we know that value of cosx and sinx can be between -1 to 1
But value of cotx can lie in between -∞ to +∞
Just for example cot30 is cos30 / sin30
= √3/2/1/2 = √3
Therefore domain of cotx is x
x ∈ R , x ≠ πn for any integer n
Yes. Yes triangles are congruent
