Select the correct answer. A mistake was made in the steps shown to simplify the expression. Which step includes the mistake?
1 + 32
5
+ |-10 = 2
Step 1: = 1+ 32 + 10 = 2
Step 2: = 1 + 9 + 10 = 2
Step 3: = 5 + 10 = 2
Step 4: = 2 + 10 = 2
Step 5: = 12 = 2
Step 6: = 6

If p(x) is the total value of the production when there are x workers in a plant, then the average productivity of the workforce at the plant is a(x) = p(x) x . (a) find a'(x). a'(x) = xp'(x) − p(x) x a'(x) = xp'(x) − p(x) x2 a'(x) = p'(x) − p(x) x a'(x) = xp'(x) − p'(x) x2 a'(x) = p'(x) − xp(x) x2 why does the company want to hire more workers if a'(x) > 0? a'(x) > 0 ⇒ a(x) is ; that is, the average productivity as the size of the workforce increases. (b) if p'(x) is greater than the average productivity, which of the following must be true? p'(x) − xp(x) > 0 p'(x) − xp(x) < 0 xp'(x) − p'(x) > 0 xp'(x) − p(x) < 0 xp'(x) − p(x) > 0
