Professor Very Busy needs to allocate time next week to include time for office hours. He needs to forecast the number of students who will seek appointments. He has gathered the following data:

  
What is this week's forecast using exponential smoothing with alpha = .2, if the forecast for two weeks ago was 90?

1. Using graphing software such as Excel^®, graph the results of Activity 1. Please see the Introduction to Graphing manual for guidance.

             a. What are the two variables that you graphed?

             b.Which is the independent variable? Should it be on the X- or Y-axis? Why?

             c. Which is the dependent variable? Should it be on the X- or Y-axis? Why?

Note: This a chemistry experiment, where we try to dissolve a Alka-Seltzer^® tablet in 3 different temp of water. C = Cold , RT = Room temp, H = Hot. Then we record the time the tablet takes to dissolve in each cup of water (we do this 3 times for each cup with different temp). I know that the independent variable is the temp and the dependent variable is the time the tablet takes to dissolve, but I do not know how to graph the data on Excel or which needs to be on the x or y axis.

The following question must be answered in the C programming language and may not be written in C++ or any other variation.

Problem 5

This problem is designed to make sure you can write a program that swaps data passed into it such that the caller's data has been swapped. This is something that is done very frequently in manipulating Data Structures.

The Solution / Test Requirements

I want your program to demonstrate that you understand how to swap information passed into a function and have the calling routine print out the data before and after the call to verify the data has been swapped. Call your functions Swap and SwapStructs. Swap is a function that receives the information to swap. The information is two integers. How should Swap receive them? How should it process them? SwapStructs is a function that receives two structs to swap. How should SwapStructs receive them? How should it process them?

Your Test Main must:

1. Declare two integers and initialize them to the values 1 and -1.

2. Print out the integers.

3. Call Swap to swap the values.

4. Print out the values on return from the function.

5. Declare a struct that holds 2 integers using a typedef for the struct.

6. Dynamically allocate two separate variables using the typedef and fill the dynamically allocated structs, filling the first with the values 10 and 20 and the second with 30 and 40.

7. Print out the values in each of the structs

8. Call SwapStructs to swap the contents of the structs.

9. Print out the values in the structs on return.

10. Free the memory that was dynamically allocated.

For your convenience, here is an output of my program:

Before call..I= 1, J=-1 After call.. I=-1, J= 1

Before SwapStructs..ptr1 contains 10 and 20

Before SwapStructs..ptr2 contains 30 and 40

After SwapStructs..ptr1 contains 30 and 40

After SwapStructs..ptr2 contains 10 and 20

Process returned 0 (0x0) execution time : 0.034 s Press any key to continue.

if you could please use the data to find these parts even just including the excel equations would help extremely please try to explain. please make it easy to follow and label things. I will 100% upvote!!

Company C is considering a new project that is expected to last for 5 years. Its marketing group expects annual sales of $40 million for the first year, increasing by $10 million per year for the following four years. Manufacturing costs (i.e., COGS) and operating expenses (excluding depreciation) are expected to be 40% of sales and $7 million, respectively, from years 1-5. Developing the product will require upfront R&D and marketing expenses of $8 million total in period 0. The fixed assets necessary to produce the product will require an investment of $20 million in period 0. The equipment will be obsolete once production ceases and (for simplicity) will be depreciated via the straight-line method over the five year period for tax purposes. The company expects to incur a $1 million net working capital outlay at the start of the project (period 0) that is recovered at the end of the project (period 5). The company has a target of 60% equity financing (E/V=0.6), a cost of debt of 5%, a cost of equity of 12%, and pays a 35% corporate tax rate. The economy-wide risk-free rate is 4%. Calculate the Net Present Value of the project. Assume the project has the same riskiness as the overall firm. Please answer in millions of dollars (e.g., if the answer is one billion dollars enter 1,000 not 1,000,000,000).

The Empire Company issues $3 million in bonds on January 1, Year One. The bonds are for three years with $1 million paid at the end of each year plus interest of 6 percent on the unpaid balance for that period. These bonds are sold to yield an effective rate of 8 percent per year. The present value of $1 at an 8 percent interest rate in one year is $0.92593, in two years is $0.85734, and in three years is $0.79383. The present value of an ordinary annuity of $1 at an 8 percent interest rate over three years is $2.57710.

a. What amount of cash will Empire pay on December 31 of each of these three years?

b. What is the present value of these cash payments at an 8 percent effective annual interest rate?

c. What journal entry or entries is recorded on December 31, Year One?

d. What journal entry or entries is recorded on December 31, Year Two?
