The equation of a parabola can be expressed ineither standard form (y = ax? + bx + c) or vertex form (y = a(x – h)² + k).Write a program that prompts the user to enter a, b, and c as integers in standard4ac – band k-bform and displays h2a| in the vertex form. Display h4aand k as rational numbers. i

1. Write a program that prompts the user to enter the length from the center of a pentagon to a verte and computes the area of the pentagon, as shown in the following figure. 5 x s? The formula for computing the area of a pentagon is Area = (€) 4 x tan Where s is the length of a side. The side can be computed using the formula s = 2r sin where r is the length from the center of a pentagon to a vertex. Round up two digits after the decimal point.
Write a program that asks user to enter number of vertices in an undirected graph and then the adjacency matrix representing the undirected graph. The program, then, must display whether the given graph is connected or not. Sample 1Enter number of vertices: 3Enter adjacency matrix:0 1 11 0 01 0 0The graph is connected.
Write a program that enables the user to addor remove points by clicking the left or right mouse button and displays a noncrossedpolygon that links all the points, as shown in Figure a.

You can plot shapes in Python using line graphs in matplot lib by providing the coordinates of the vertices of the shapes as x, y pairs and using the matplotlib.pyplot.plot (i.e. plt.plot) function. Draw a triangle, square, pentagon, hexagon and heptagon. Note: Use symmetry, starting with the origin at (0,0), and set the distance from the origin to the vertex to be of length 1.0 (otherwise this becomes very complicated for some shapes).
Given below are two statements: S1: If a Graph G is n colorable then it's also n+1 colorable. S2: Every Bipartite graph is 2 colorable Which of the above statement(s) is/are correct?

Using Javascript and HTML: An interesting application of computers is drawing graphs and bar charts (sometimes called histograms). Write a script that reads five numbers between 1 and 30. For each number read, output HTML5 text that displays a line containing the same number of adjacent asterisks. For example, if your program reads the number 5, it should out HTML5 test that displays *****.
Create a program that provides visualization for three-dimensional plane: Animate your solution using any animation programming language like matlab please. (so the output should show graph of the exponential function inputted by the user)the system should be user-input, and the output should show graph of the exponential function inputted by the user) The topic is all about Inverse Laplace Transform on Exponential function.
A popular word game involves finding words from a grid of randomly generatedletters. Words must be at least three letters long and formed from adjoining letters.Letters may not be reused and it is valid to move across diagonals. As an example,consider the following 4 * 4 grid of letters: A B C DE F G HI J K LM N O P The word “FAB” is valid (letters in the upper left corner) and the word “KNIFE”is valid. The word “BABE” is not valid because the “B” may not be reused. Theword “MINE” is not valid because the “E” is not adjacent to the “N”. Write a program that uses a 4 * 4 two-dimensional array to represent the gameboard. The program should randomly select letters for the board. You may wishto select vowels with a higher probability than consonants. You may also wish toalways place a “U” next to a “Q” or to treat “QU” as a single letter. The programshould read the words from the text file words.txt (included on the website withthis book) and then use a recursive algorithm to…
please code in python You place a pawn at the top left corner of an n-by-n chess board, labeled (0,0). For each move, you have a choice: move the pawn down a single space, or move the pawn down one space and right one space. That is, if the pawn is at position (i,j), you can move the pawn to (i+1,j) or (i+1, j+1). Ask the user for the size of a chessboard, n (integer). Find the number of different paths starting from (0,0) that the pawn could take to reach each position on the chess board. For example, there are two different paths the pawn can take to reach (2,1). Look at the diagrams below to convince yourself of this. You can see the four paths that you can take by move 2. Start -> Move 1 -> Move 2 (0,0) -> (1,0) -> (2,1) (0,0) -> (1,0) -> (2,0) (0,0) -> (1,1) -> (2,1) (0,0) -> (1,1) -> (2,2) Print the board with the number of ways to reach each square labeled as shown below. For example: Enter a board size: 4 1 0 0 0 1 1 0 0 1 2 1 0 1 3 3 1
IN JAVA Alice and Bob are playing a board game with a deck of nine cards. For each digit between 1 to 9, there is one card with that digit on it. Alice and Bob each draw two cards after shuffling the cards, and see the digits on their own cards without revealing the digits to each other. Then Alice gives her two cards to Bob. Bob sees the digits on Alice’s cards and lays all the four cards on the table in increasing order by the digits. Cards are laid facing down. Bob tells Alice the positions of her two cards. The goal of Alice is to guess the digits on Bob’s two cards. Can Alice uniquely determine these two digits and guess them correctly? Input The input has two integers p,q (1≤p<q≤9) on the first line, giving the digits on Alice’s cards. The next line has a string containing two ‘A’s and two ‘B’s, giving the positions of Alice’s and Bob’s cards on the table. It is guaranteed that Bob correctly sorts the cards and gives the correct positions of Alice’s cards. Output If Alice can…
