Kite 'N String: Maximum Profit Using Linear Programming

Kite 'N String manufacture old-fashioned diagonal and box kites from high-strength paper and wood. Each diagonal kite nets the company a $3 profit, requires 8 square feet of paper and 5 feet of wood. Each box kite nets $5, requires 6 square feet of paper and 10 feet of wood. Each kite is packaged in similar containers. This week Kite 'N String have 1500 containers, 10000 square feet of paper and 12000 feet of wood.

a) How many of each type should Kite 'N String make to maximize profit? What is the maximum profit?
b) Which constraint(s) is/are binding?
c) If an additional 2000 square feet of paper is available, how many of each type to make to maximize profit? What is the maximum profit?
d) Which constraint(s) is/are binding for part 3?

a) How many of each type should Kite 'N String make to maximize profit? What is the maximum profit?
b) Which constraint(s) is/are binding?

Using regular arrangement of data:
Paper (in square feet) Wood (in in square feet) Profit
Diagonal kite (x) 8x 5x 3x
Box Kite (y) 6y 10y 5y
Total 10000 12000
Maximize: 3x + 5y
subject to: 8x + 6y = 10000
5x + 10y = 12000

A linear program has the objective of maximizing profit = 12X + 8Y. The maximumprofit is $8,000. Using a computer we find the upper bound for profit on X is 20 and the lower bound is 9. Discuss the changes to the optimal solution (the values of the variables and the profit) that would occur if the profit on X were increased to

Please find the horizontal and vertical components of F in the problem below:
A kite string exerts a 12-lb pull (F=12) on a kite and makes a 45° angle with the horizontal. Find the horizontal and vertical components of F.

The Apex Television Company has to decide on the number of 27" and 20" sets to be produced at one of its factories. Market research indicates that at most 40 of the 27" sets and 10 of the 20" sets can be sold per month. Maximum number of work hours available is 500 per month. A 27" set requires 20 work hours and 20" set requires

Using the information below, in a linearprogramming problem, maximize the profit for product A and B.
Maximize profit $80A+$60B
Subject to the following constraints
15A+10B<=1200
19A+5B<=1000
A,B=>0
How many of each product should be produced and what is the profit at that level?

A kite 100ft above the ground moves away horizontally at a speed of 8ft/sec. At what rate is the angle between the string and the horizontal decreasing when 200ft of string has been let out?

Which of the following could be a linearprogramming objective function?
Z = 1A + 2B / C + 3D
Z = 1A + 2BC + 3D
Z = 1A + 2B + 3C + 4D
Z = 1A + 2B2 + 3D
all of the above.

Lines with special relationships to the sides and angles of a triangle determine proportional segments. When you know the length of some segments, you can use a proportion to find an unknown length.
You are making the kite shown on the right (see attachment) from five pairs of congruent panels. In parts (a) - (d) below, use
