Solve the problem using trigonometric substitution. Hint: write each term in the radical as the square of another term. Find the average value of the function
f(x)=(20)/(\sqrt(9-25x^(2)))
on the interval from
a=0
to
b=(3)/(10)
. The average value of
f(x)(,)/(b)ar (f(x))=(1)/(b-a)x\xi nt_(a)^(b)f(x)dx
.
