Answer:
315 miles
Step-by-step explanation:
4.5 hours = (4.5 x 60 min) = 270 minutes
70 miles in 60 minutes
z miles in 270 minutes
Cross multiplication:
z = (70 x 270)/ 60
z= 315 miles
Answer:
X=20
Step-by-step explanation:
Verticals angles have same degree.
3x=x+40
x=20
The first integral has a well-known beta function representation, so the second one should too. The beta function itself is defined as
and satisfies the identity
Later on, we'll also use the so-called reflection formula for the gamma function; for non-integer z,
as well as the identity
Replace in both integrals, so that
Now replace :
So, the original integral (which I condense here to a double integral) is
