Answer: 88.74
Step-by-step explanation:
Answer: Marginal cost = $46
The cost of production increases by about $46 when one additional unit is produced.
Step-by-step explanation:
Given : The cost to produce q items is
dollars.

The marginal cost of producing the 12th item= C(12)-C(11)
=1588-1542=46
Interpretation : It means , the cost of production increases by about $46 when one additional unit is produced.
Answer:
The first derivative of
(r(t)=5*t^{-2}) with respect to t is
(r'(t) = -10*t^{-3}).
Step-by-step explanation:
Let be
, which can be rewritten as
. The rule of differentiation for a potential function multiplied by a constant is:
, 
Then,

(r'(t) = -10*t^{-3})
The first derivative of
(r(t)=5*t^{-2}) with respect to t is
(r'(t) = -10*t^{-3}).
