Plot the following parabolic functions in Excel and then answer the discussion question below . Use at least 8 points for each plot: Each graph is worth 15 points and must include 8 points. 1) y=x2-6x+8 2) y=x2+4 3) y=(-1/2)(x2) 4) What is the maximum number and the minimum number of x-intercepts for a parabola? Why? (15 points) In order to obtain full credit, you will need to plot the functions in Excel or using the Open Office feature and attach the results to your response.

2.A 4-year project has a projected cash inflow of $5,000 in the first year, $10,000 in the second year, $15,000 in the third year, and $20,000 in the fourth year. It will cost $19,000 to implement the project. The required rate of return is 25%. What is the NPV?  

Write a method public static void minMax(int[] arr) that takes an array of unique ints of length at least two as an argument, and swaps the smallest value of the array into the 0th position and swaps the largest value of the array into the last position.

For example, if int[] a = {4, 3, 2, 6, 1, 5}, the method call minMax(a) should modify the array so that it is {1, 3, 2, 5, 4, 6}.

The method should make only one pass through the array.

The method should not return a value. Instead, it should modify the array in place.

Identify THREE (3) characteristics human share with other living organisms. Define differentiation. Which body system is associated with the regulation of fluid volume and composition? Provide the proper anatomical name for the following body regions: 1) head; 2) forearm; 3) wrist; 4) leg; 5) ankle. What anatomical plane divides the body into equal left and right halves? Define the following terms: 1) contralateral; 2) ventral; 3) inferior; 4) proximal. The ventral body cavity can be subdivided into which two cavities?

5 years ago P&G issue debt with following parameters: $1000 face value, 6% coupon, paid semi-annually, 10 years to maturity

1)It today current interest rate for bonds are selling at annual yield to maturity of 4% what is price of P&G bond today?

2)If you were to buy bond in part 1 at price you calculatedand 4 years later interest rates and maturities are now 2%

A. What is price of bond at that time?

B. What would total % return be?

Create a static method with the appropriate inputs and outputs. Call each of them in the main method.

Write a method called removeAllInstances() which takes in a List and item4 . The method then proceeds to remove each item in the list that matches the given item. For example, if the method is passed the List [1, 4, 5, 6, 5, 5, 2] and the Integer 5, the method removes all 5’s from the List. The List then becomes [1, 4, 6, 2]. It should return nothing, since the changes the List it was provided. 5

Five kilograms of ammonia (NH3) undergo a refrigeration cycle
detailed as:
• Process 1-2: isothermic expansion from saturated vapor at 10ºC, to P = 3 bar with
Q = 400 kJ.
• Process 2-3: isochoric cooling to 0 ◦C.
• Process 3-4: isobaric compression.
• Process 4-1: isochoric heating.

Calculate:

a) the P −v and T −v diagrams.

b) the states table detailing P, v, T and u.
c) the process table for Q, W and ∆U.
d) the performance coefficient, β, of the cycle.
