In Java, what is the advantage of using ArrayList over arrays? Write a program to perform following operations
a. Create a class named Rectangle with two
properties “height” and “width”. Create a parameterized
constructor to initialize “height” and “width” values.
b. Write method area() to calculate and return area of Rectangle.
c. Create an ArrayList to store Rectangle objects.
d. Create three Rectangle objects of width and height set to
(2, 3), (3, 3) and (4, 5) and add them to ArrayList.
e. Calculate and print area of all the Rectangle objects in
ArrayList. (Hint: Area = height x width)

1. Suppose there is a nation which produces and consumes just calculators and notebooks in the following amounts:

1. Using the CPI, compute the percentage change in the overall price level. Use 2018 as the base year and fix the basket at 2 calculators and 6 notebooks.
2. Using the GDP deflator, compute the percentage change in the overall price level. Also use 2018 as the base year.
3. Is the inflation rate in 2019 the same using the two methods? Explain why or why not.

Topic is Spirulina.

Spirulina is a micro-algae and as such has been growing naturally in our environment for millions of years, it is a tough plant able to withstand harsh growing conditions, in fact the micro-algae cell never really dies it goes dormant when weather conditions are not favourable, and as soon as these change and the environment is once again suitable for growth, spirulina begins growing and reproducing again. Naturally growing spirulina can be found in high alkaline lakes and in general it is said that where flamingos are, spirulina is sure to be found.

Question:

Describes your audience and how you will reach them. Share who you plan to sell your product/service to, being as specific as possible. While virtually anyone could purchase your product/service, is that realistic given how you will sell/market your idea? Who is your ideal customer? Give a good description of this individual. You should include a minimum of one source that shows why this audience is ideal.

Describe the best ways to communicate with your target market. This part should clarify the best medium/channel combinations to reach your audience as described in the previous paragraph and how they will be used. You need a minimum of one source to back up why you are using the channel(s) chosen.

A 0.26 kg mass is attached to a light spring with a force constant of 36.9 N/m and set into oscillation on a horizontal frictionless surface. If the spring is stretched 5.0 cm and released from rest, determine the following.

(a) maximum speed of the oscillating mass
m/s

(b) speed of the oscillating mass when the spring is compressed 1.5 cm
m/s

(c) speed of the oscillating mass as it passes the point 1.5 cm from the equilibrium position
m/s

(d) value of x at which the speed of the oscillating mass is equal to one-half the maximum value
m

.The integrated ownership of pipelines was initially used by some oil companies to gain control of oil-producing area. How did they use their transportation network to gain market control? What other reasons can be offered for integrated ownership? Are these reasons valid in today’s business environment?

A voltaic cell utilizes the following reaction and operates at 298 K. 3 Ce4+(aq) + Cr(s) 3 Ce3+(aq) + Cr3+(aq)

(a) What is the emf of this cell under standard conditions? V

(b) What is the emf of this cell when [Ce4+] = 2.0 M, [Ce3+] = 0.014 M, and [Cr3+] = 0.011 M? V

(c) What is the emf of the cell when [Ce4+] = 0.56 M, [Ce3+] = 0.82 M, and [Cr3+] = 1.3 M? V

The International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airports. The maximum possible rating is 10. Suppose a simple random sample of 50 business travelers is selected and each traveler is asked to provide a rating for the Miami International Airport. The ratings obtained from the sample of 50 business travelers follow.

Develop a 95% confidence interval estimate of the population mean rating for Miami (to 2 decimals).

CTC is an on-line retailer of prescription drugs and health supplements. Vitamin-C represents a significant percentage of its sales. Demand for Vitamin-C is 12000 bottles per year. CTC incurs a fixed order placement, transportation, and receiving cost of $150 each time an order for Vitamin-C is placed with the manufacturer. CTC incurs a holding cost of 25 percent. The price charged by the manufacturer is $4/bottle. Each time CTC places an order, the manufacturer has to process, pack, and ship the order. The manufacturer has a line packing bottles at a steady rate and does not keep any inventory. The fixed cost of filling each order is $350 for manufacturer.

1. Under the non-collaborative environment, the above supply chain uses CTC’s EOQ policy. Please evaluate CTC’s annual ordering and holding costs and Manufacturer’s annual ordering cost and holding cost under the CTC’s EOQ policy. What is the total annual ordering and holding cost for this supply chain under this non-collaborative policy?
