C = 2 × pi × r
C= 2 × pi × 2.5
Your answer is
C = 5 × pi
Yo sup??
For our convenience let h=x+1
therefore
when x tends to -1, h tends to 0
hence we can rewrite it as

This inequality is of the form 1∞
We will now apply the formula

plugging in the values of g(x) and f(x)

express coth² as cosh²/sinh² and also write cosh-1 as 2sin²(h/2)
(by applying the property that cos2x=1-sin²x)
After this multiply the numerator and denominator with h² so that we can apply the property that

Now your equation will look like this.

We will now apply the result

where x=h²
we get

we now multiply the numerator and denominator with 4 so that we can say



Apply the limits and you will get


Hope this helps.
Answer:
Step-by-step explanation:
10 hours - 2 hours 25 minutes - 3 hours 35 minutes
Lets just do this
2 hours 25 minutes + 3 hours 35 minutes
25 minutes + 35 minutes = 60 minutes
60 minutes = 1 hour
now we have 2 hours + 3 hours + 1 hour
2 + 3 +1 = 6
now we have 10 hours - 6 hours
10 - 6 is 4
4 hours.
