Tristan swam around a lake 8 times. the distance around the lake was 0.25 miles. he swam at an average of 60 minutes per mile. which explanation correctly tells how to calculate the time it will take tristan to complete his swim? a. step 1: figure out the total number of miles tristan swam (8 × 0.25). step 2: divide that distance into his average speed (60 ÷ 2). b. step 1: figure out the total number of miles tristan swam (8 ÷ 0.25). step 2: multiply that distance by his average speed (32 × 60). c. step 1: figure out the total number of miles tristan swam (8 ÷ 0.25). step 2: divide that distance by his average speed (32 ÷ 60). d. step 1: figure out the total number of miles tristan swam (8 × 0.25). step 2: multiply that distance by his average speed (2 × 60).

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
