Create a nicely formatted table (See solution for In-Class 1) that shows the value of x, the volume of the box, and the surface area of the box. Use 1 sx s 3, with an increment of 0.25 cm. Problem 2 Burning one gallon of gasoline in your car produces 19.4 pounds of CO1. Calculate the amount of CO, emitted during a year for the user's vehicle. You should ask the user for the vehicle's fuel efficiency in mpe, and total mileage traveled in one year, your solution will return the amount of C02 emitted by the user's vehicle during that one year. Mileage Problem ii Chemical reaction rates are proportional to a rate constant k that changes with temperature according to the Arrhenius equation k = koe- For a certain reaction, Q = 8000 cal/mol R 1.987 cal/mol K ko = 1200 min-1 Find the values of k for 11 linearly equally spaced temperatures (T) from 100 K to 500 K inclusively.

Answer 1

%% Script by:
% Introduction to Engineering I - Section:
% Spring 2019 - MATLAB Homework I
% April 16, 2019

%% Problem 1
clear,clc;
x=[1:.25:3]'; %create x with increaments of 0.25
h=6; %height of the box
base_area=x.*x; %This is the area of the base
volume_box=h.*base_area; %volume of the box;
surface_area=h*4*x+2*x.*x; %Surface area of the box
display(table(x,volume_box,surface_area));

%% Problem 2
clear,clc;
efficiency=input('Please Enter the Fuel Efficiency of your Vehicle in miles per gallon (mpg): ');
mileage=input('Please enter the total mileage in one year: ');
emissions=19.4*(mileage/efficiency);
fprintf('The total amount of Carbon dioxide emission in one year is %f pounds\n',emissions);

%% Problem 3
clear,clc;
T=linspace(100,500,11); %creates 11 equally spaced values between 100 and 500
Q=8000;
R=1.987;
k0=1200;
k=k0*exp(-Q./(R*T)); %exp is used for exponential function
display(table(T',k','VariableNames',{'Temperature' 'Rate'}));

%% Problem 4
clear,clc;
a=[15 3 22;3 8 5;14 3 82]; %This is the matrix a
b=[1;5;6]; %This is the matrix b
c=[12 18 5 2]; %This is the matrix c
