Problem 2.3.Suppose that you enter into a short futures contract to sell July silver for $17.20 per ounce. The size of the contract is 5,000 ounces. The initial margin is $4,000, and the maintenance margin is $3,000. What change in the futures price will lead to a margin call? What happens if you do not meet the margin call? Problem 2.4.Suppose that in September 2018 a company takes a long position in a contract on May 2019 crude oil futures. It closes out its position in March 2019. The futures price (per barrel) is $48.30 when it enters into the contract, $50.50 when it closes out its position. One contract is for the delivery of 1,000 barrels. What is the companys total profit? Problem 2.11.A trader buys two July futures contracts on frozen orange juice concentrate. Each contract is for the delivery of 15,000 pounds. The current futures price is 160 cents per pound, the initial margin is $6,000 per contract, and the maintenance margin is $4,500 per contract. What price change would lead to a margin call? Under what circumstances could $2,000 be withdrawn from the margin account?

Acceleration due to Earth's gravity is known to be around -10(m)/(s^(2)). The negative sign represents the choice that "up" should be positive and "down" (toward Earth) is negative. This is the only acceleration experienced by an object in freefall. Suppose that a rock is dropped from the top of a building that's 45 meters tall. a. Find the height h(t) (in meters) at time t (in seconds) of the rock above the ground. (Hint: h(t) is a quadratic polynomial h(t)=at^(2)+bt+c with h(0)=45 (the initial height), h^(')(0)=0 (the initial velocity), and h^('')(0)=-10 (the constant acceleration). Can you find a,b,c ?)

larryfish Today at 2:22 PM For this Lab, you will create 3 classes: Counter Top, Laminate, Granite. The Counter Top will be the super class to the other 2 classes. The shared field variables will be the length, width and depth. The Laminate will have field variables for pattern. The Granite class will have a field variable for name and origin (country it came from). Use appropriate names and datatypes for all field variables. Create appropriate constructors for each class (a default and one that passes in the data). Create the appropriate get and set methods. All classes should have a toString method. The subclasses should utilize the super class's toString method. Inside the Counter Top class, create a main method. Inside the main method, make an ArrayList that stores Counter Top objects. Create at least one of each class and add it to the ArrayList. Then loop through the ArrayList and output the details for each object. Message @larryfish
