In problem #14, find the Derivative of each expression. Use correct notation for each Derivative! NOTE: Algebraic simplification of each Derivative result is NOT required.

In problem #14, find the Derivative of each expression. Use correct notation for each Derivative! NOTE: Algebraic simplification of each Derivative result is NOT required. Then do each part of problem #5, an application of derivatives for Marginal Analysis.

1) y = (3x1.5 - 1.5x2 ) ( 12x3 + 135)

2) y = (6t4 - 3t2.5 + 800) (t3.5 + 25t-2)

3) f (t) = 11t3 - 8t1.5 /4t2.2 + 13

4) f(x) = 41x0.7 - 100x1.4 / 3600 + 8x2.5

Answer all parts of Problem #5 below. Show all work! (Refer to Module #4 for Examples and terminology.) 5) A local company makes and sells cabinet hinges for modular homes. Selling price "p" per hinge is related to weekly demand "X" by the relation: p = 12 - 0.002x ("p" measured in dollars). The company's total cost per week is given by: C(x) = 4.25X + 3250

a) Find the expression for the company's Revenue function.

b) Find the expression for the company's Marginal Revenue.

c) Find the Incremental Revenue associated with the 1801st hinge that is made and sold in a week. (Solve to the nearest penny.)

d) Find the expression for the company's Profit function.

e) Find the expression for the company's Marginal Profit.

f) Find the Incremental Profit associated with the 1000th hinge that is made and sold in a week. (Solve to the nearest penny)
