Answer:

(a) fave = 8

(b) c = 64/9

Step-by-step explanation:

(a) The average value of the function is its integral over the interval, divided by the width of the interval.

$f_{ave}=\displaystyle\frac{1}{16-0}\int_0^{16} {3x^{\frac{1}{2}}} \, dx=\left.\frac{x^{3/2}}{8}\right|_0^{16}=8$

(b) We want ...

f(c) = 8

3√c = 8 . . . . . use f(c)

√c = 8/3 . . . . . divide by 3

c = (8/3)² . . . . square

c = 64/9

(c) c ≈ 7.111
