Chapter 15, Problem 9RQ
You are studying the properties of tiny spheres generated by an automated process. You collect data on a large number of the spheres and record this data in the two-row matrix SphereData Each pair of values (each column) represents the data for a specific sphere. The first row of sphereData contains the diameters of the spheres in millimeters; the second row contains the masses of the corresponding spheres in micrograms. Write a single MATLAB command to achieve each of the following tasks.
a. Create a third row in sphereData that contains the volumes [cubic millimeters] of the corresponding spheres represented in the first two rows of sphereData
b. Create a fourth row in sphereData that contains the specific gravities of the corresponding spheres represented in sphereData
c. Create a column
First element: Average diameter of all spheres
Third element: Maximum diameter of all spheres

How do I input this code for this MATLAB problem? Thanks!
I need help with the purple line the line that you see one the graph on the picture needs to be on the graph.
Use this code to add the purple line and make sure it’s crossing the orange line. Please make sure the lines are positioned the same way it is shown on the picture with the graph.
Use this code on MATLAB and add the purple line.
% Sample data for Diesel and Petrol cars
carPosition = linspace(1, 60, 50); % Assumed positions of cars
% Use the 'seed' function instead of 'rng'
seed = 50; % Define your seed here
rand('seed',seed);
% Assumed CO2 emissions for Diesel and Petrol
CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel
CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol
% Fit polynomial curves with a reduced degree of 2

Hi I need help to make the line change into a different color, I half of the line to be orange and I need the other half of the line towards the end to be purple as shown in the picture. Also I need there be a box saying Diesel, petrol, diesel best fit, petrol best fit. This part is also shown in the graph.
Please use this code and fix it in MATLAB:
% Sample data for Diesel and Petrol cars
carPosition = linspace(1, 60, 50); % Assumed positions of cars
% Fix the random seed for reproducibility
rng(50);
% Assumed positions of cars
CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel
CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol
% Fit polynomial curves
pDiesel = polyfit(carPosition, CO2Diesel, 3);
pPetrol = polyfit(carPosition, CO2Petrol, 3);
% Generate points for best fit lines

- I created a MATLAB code to plot the orbit of a satellite at an altitude of 300 km (LEO). I wanted to propagate my code for 2 revolutions but instead I used (180*60) because it takes 90 minutes to make a full rotation around the earth in LEO. Is that correct? Also, if I wanted to use revolutions how would I propagate it for 2 revs? Would my t = [0 4*pi].arrow_forwardMatlab Codearrow_forwardUse MATLAB please make code for this.arrow_forward
