Task 4: Matplotlib Import the plotting function by the command: import matplotlib.pyplot as plt Plotting multiple lines Compute the x and y coordinates for points on sine and cosine curves and plot them. on the same graph using matplotlib. Add x and y labels to the graph as well. Note:

make the following 2 codes into a graph. import matplotlib.pyplot as plt # Stock prices at expirationstock_prices = [45, 50, 55, 60, 65]# Profit/Loss calculationsprofits_losses = [price - 55 for price in stock_prices] # Plotting the graphplt.figure(figsize=(10, 6))plt.plot(stock_prices, profits_losses, marker='o', linestyle='-', color='b', label='Buy and Hold Stock') # Adding labels and titleplt.xlabel('Stock Price at Expiration ($)')plt.ylabel('Profit/Loss per Share ($)')plt.title('Profit/Loss for Buying and Holding Lotus Stock')plt.axhline(0, color='gray', linewidth=0.5)plt.axvline(55, color='gray', linewidth=0.5, linestyle='--')plt.legend()plt.grid(True) # Show the plotplt.show() ----- import matplotlib.pyplot as plt # Stock prices at expirationstock_prices = [45, 50, 55, 60, 65]# Profit/Loss calculationsprofits_losses = [price - 55 for price in stock_prices] # Plotting the graphplt.figure(figsize=(10, 6))plt.plot(stock_prices, profits_losses, marker='o', linestyle='-', color='b',...

Awesome! the program is running perfectly! Lastly, instead of using a Hashmap, can this be done just using a LinkedList where the output should stay the same, but not using a Hashmap?

DO NOT COPY FROM OTHER WEBSITES Code with comments and output screenshot is must for an Upvote. Thank you!!!

Please help with the program below. Need to write a program called dfs-stack.py in python that uses the algorithm below without an agency list but instead uses an adjacency matrix. The program should prompt the user for the number of vertices V, in the graph.Please read the directions below in the image I will post a picture of the instructions and the algorithm.

The implementations of the methods addAll, removeAll, retainAll, retainAll, containsAll(), and toArray(T[]) are omitted in the MyList interface. Implement these methods. Use the template at https://liveexample.pearsoncmg.com/test/Exercise24_01_13e.txt to implement these methods this the code i have for the write your own code part import java.util.Iterator; interface MyList<E> extends java.util.Collection<E> { void add(int index, E e); boolean contains(Object e); E get(int index); int indexOf(Object e); int lastIndexOf(E e); E remove(int index); E set(int index, E e); void clear(); boolean isEmpty(); Iterator<E> iterator(); boolean containsAll(java.util.Collection<?> c); boolean addAll(java.util.Collection<? extends E> c); boolean removeAll(java.util.Collection<?> c); boolean retainAll(java.util.Collection<?> c); Object[] toArray(); <T> T[] toArray(T[] a); int size();} and its...

Is there a consequence for adding a new key-value pair to an existing map entry?

Implement the following by extending the Cubes project. For all shapes, there should be no colocated vertices. For the meshes, you may use arbitrary indexed convex-polygon faces that G3D will automatically tessellate into triangles on load. This project's report requires you to plan your approach before you begin writing code, so read the whole document before beginning implementation. Create data-files/model/cube.off, an axis-aligned cube with unit edge lengths, centered at the origin. You may make this file in a text editor directly, or write a procedure to generate it. Create a procedure (function or method) named makeCylinderthat generates a file data-files/model/cylinder.off given a radius and height. This file should be an indexed convex-polygon mesh for a cylinder about the yy-axis that is centered at the origin. Create a user interface for invoking makeCylinder. Use number boxes for the parameters and a button labelled "Generate" to actually launch the execution. Display a...

The sink contains two labels, the first label indicates its predecessor of the edge and the second label indicates the number of units we can change along the edges in the path. O True O False K

new JAVA code can only be added between lines 15 and 17. as seen in image.

implement a grid transformation that reduces the size of the grid, while retaining the information in it in python 3 __init__(self, size: int): create a square 2-D grid of ints with size rows and size columns. Initialize all values to 0. set_value(self, i: int, j: int, val: int): set the value in the i-th row and j-th column to val. squish(self, k:int): Sum up the elements of k by k blocks of the grid. This method does not return anything, but rather modifies the grid object. The size of the modified grid is n / k where n was the original size. You can assume that the grid's size is divisible by k.
