Answer:
(a) fave = 8
(b) c = 64/9
(c) c ≈ 7.111
Step-by-step explanation:
(a) The average value of the function is its integral over the interval, divided by the width of the interval.

__
(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
Answer:
9.899495
Step-by-step explanation:
=(0−(−7))2+(−6−1)2−−−−−−−−−−−−−−−−−−−√
d=(7)2+(−7)2−−−−−−−−−−√
d=49+49−−−−−−√
d=9–√8
d=9.899495
X would equal 9. Subtract 18 from both sides then divide by two to get 9 as X
2 significant digits should be represented in the product
