A manufacturer estimates that when q units of a certain commodity are produced, the total cost will be

C(x) rand where

C(q) = q2

25 + 80 000 − 104q.

Answer the following questions:

(i) Use marginal analysis to determine the production level at which the cost will be a minimum.

(ii) Determine the minimum cost.

Evaluate limits involving the expressions (sin t/t), (1 - cos t)/t) and ((e ^ t- 1)/t) and indeterminate forms type "0/0"

Directions: Create example of limits of functions and evaluate their limits.

1.(sint)/t

2.(1 - cos t)/t

3.(e ^ t - 1)/t

1.(sint)/t

2.(1 - cos t)/t

3.(e ^ t - 1)/t

Evalute limits involving the by constructjng their respective table of values

1.lim t -> 0 t/(sin t)

2.lim t -> 0 (sin t)/(2t)•(1 - cot t)/t

3.lim t -> 0 (e ^ t - 1/t)

A company determines that in order to sell x

x

 items the price per item, in dollars, must be p(x)=1830

p(x)=1830. The company also determines that the total cost, in dollars, to produce x x

 items is given by C(x)=3100+610x+1.5x2C(x)=3100+610x+1.5x2. 

How many items must the company produce and sell in order to maximize profit? 

The company must produce and sell
