Pierce manufacturing determines that the daily revenue, in dollars, from the sale of x lawn chairs is r(x)equals0.006 x cubed plus 0.02 x squared plus 0.5 x. currently, pierce sells 50 lawn chairs daily. a) what is the current daily revenue? b) how much would revenue increase if 54 lawn chairs were sold each day? c) what is the marginal revenue when 50 lawn chairs are sold daily? d) use the answer from part (c) to estimate r(51), r(52), and r(53).

a) $825

b) $205.10

c) $47.5

d) R(51) = 872.5, R(52) = 920, R(53) = 967.5

Step-by-step explanation:

We are given the following information in the question:

where x is the number of lawn chairs.

a) Current daily revenue

Thus, $825 is the current daily revenue when Pierce sells 50 lawn chairs daily.

b) Revenue increase if 54 lawn chairs were sold each day

Thus, revenue increase $205.10 if 54 lawn chairs were sold each day.

c) Marginal revenue

Thus, $47.5 is the marginal revenue when 50 lawn chairs are sold daily.

d) R(51), R(52), and R(53)

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64
