ENGR 1020 Freshman Engineering Seminar Final Assessment

Name

Date

Directions

SHOW YOUR COMPLETE WORK (steps, calculations, assumptions, etc.) if you would like to RECEIVE ANY CREDIT

NOTE 1: This is an Individual Assessment and NOT a Group Assessment. If any solutions are the same, then each of those students will receive a grade of a “0” on the Final Assessment and those students will repeat the course again next semester.

NOTE 2: For each problem, you can either solve the problem using R or MATLAB(R)/GNU Octave (no Microsoft Excel) and/or you can solve the problem by hand on engineering paper and/or here (feel free to use the backside). If using R or MATLAB(R)/GNU Octave, then include your complete source code (input) along with your answers (output).

Be sure to include units and use significant figures appropriately

Write neatly in pencil — work in pen will NOT be accepted

You will have until 4:55 PM on Wednesday, 2 December 2015 and no LATER to turn the Final Assessment in to me in Holland Hall 106, thus the Assessment can not be e-mailed to me.

Cite your references as needed (use the citations at the end of this Assessment and/or the Mid-Term Report for reference)

Read the directions carefully

[4 points total] *14) “… In all of these cases, the agenda to recycle has supserseded other design consider- ations.

F = P ∗ (1 + i)n

Write a function that will calculate the future worth of an investment for each year from 1 through n. The input to the function should include the initial investment P, the interest rate i (as a decimal), and the number of years n for which the future worth is to be calculated. The output should consist of a table with headings and columns for n and F. Run the program for P = £285,940.45 (British pound), i = 7.1284%, and n = 17 years. Provide the table in US dollars.
