You are to write a program using Java that will simulate a slot machine with four wheels. It will determine the amount of money won for each spin. The four wheels spin and stop showing a value between 0 and 9 inclusive. It costs $2 to play.

•You win $500 (but not the $2 you bet) if you get 4 wheels the same.

•You win $10 (but not the $2 you bet) if you get exactly 3 of a kind.

•You win $5 (but not the $2 you bet) if you get two pairs.

•You win $2 if you get 2 wheels the same (That is, you break even).

•You win nothing and lose your $2 bet if you get no matches.

Your program must use 4 methods:

1.One to randomly generate the 4 wheel values.

2.One to output the result of the spin.

3.One to compute the win or loss and print the correct message

4.Finally, one to output new balance and a nice line break graphic as seen below.

Input and Output:Your program will randomly generate a starting balance between $100 and $200 inclusive. Your program will randomly generate four integers (1 for each wheel).Your program will output a description of the input combination and the amount you won or lost.Your program will output your new balance after each spin.

5. [6 pts] A particle moves along a coordinate line and has an acceleration given by a(t) = 4t+ 6 cm/sec2 . If the particle’s initial velocity is v(0) = −2 cm/sec, and its initial position is s(0) = 4 cm, find its position function s.

The management of Electronics Company is considering to purchase an equipment to be attached with the main manufacturing machine. The equipment will cost $8,000. The useful life of the equipment is 4 years. Management projected that annual cash inflow for four(4) years as follow: year-1 $1,000, year-2 $3000, year-3 $3500 and year-4 $4000. There’s maintenance cost for the equipment, and management should expense: $600 on year-2 and $800 on year-4. The management wants a 14% return on all investments. a. Compute net present value (NPV) of this investment. b. Should the equipment be purchased according to NPV analysis?

Suppose there are two consumers, A and B.

The utility functions of each consumer are given by:

UA(X,Y) = X^1/2*Y^1/2

UB(X,Y) = 3X + 2Y

The initial endowments are:

A: X = 4; Y = 4

B: X = 4; Y = 12

a) (10 points) Using an Edgeworth Box, graph the initial allocation (label it “W”) and draw the

indifference curve for each consumer that runs through the initial allocation. Be sure to label your graph

carefully and accurately.

b) (3 points) What is the marginal rate of substitution for consumer A at the initial allocation?

c) (3 points) What is the marginal rate of substitution for consumer B at the initial allocation?

d) (2 points) Is the initial allocation Pareto Efficient?
