The support functions For the next few questions, we'll be working on finding the roots for the following quadratic equation: f(x)=x²-1.5 which has the derivative: f'(x)=2r Before we get started on the root-finding, however, you are to write two functions that will come in handy later: f(x), which takes a number or numpy arrayx and returns f(x) as defined above. • f_prine(x), which takes a number or numpy arrayx and returns f'(x) as defined above. Paste these two functions into the answer box below. Note: Each function can easily be written using just a return statement. If you're doing more than this, yo For example: Test x = 2 print(f(x0)) print(f_prine(x@)) Result 2.5 4 Answer: (penalty regime: 0, 10, 20, ... %) s, you're probably overthinking it.

The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() function, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1 Ex: If the input is: 7 the output is: fibonacci (7) is l3 Note: Use recursion and DO NOT use any loops.
Write a fraction calculator program that adds, subtracts, multiplies, and di-vides fractions. Your program should check for the division by 0, have and use the following functions:(a) subtract - finds the reduced difference of a pair of given fractions, by makingthe second fraction negative then using the add function.(b) multiply - finds the reduced product of a pair of given fractions.(c) divide - finds the reduced quotient of a pair of given fractions by inverting the second fraction then using the multiply function
Counting Operations to Produce Polynomials In the following section, I will present you with multiple different bodies of code, and it is your job to analyze each code section and build a polynomial that represents the number of abstract operations the code performs. Once we’re done here, we’ll have built a polynomial that we will analyze further (in terms of g(x), c, 5 and k) in the next section. For the following code segments below, count the operations and produce a corresponding polynomial representation. f(x)= public static boolean isEmpty() {return head == null;} f(x) public static int num_occurrences(int n) {int count = 0;for(int i = 0; i < n; i++) {for(int j = 0; j < n; j++) {if( i == j ) continue;if(strings[i] == strings[j]) {count++;}}} return count;} f(x) public static void c(int n) {for(int a = 0; a < n; a++) {System.out.println( a * a);}num_occurrences(n);} f(x) public static boolean isPrime(int n) {if(n == 1) return false;for(int i = 2; i <n; i++) {if( n % i…
please code in python MCQ are a very popular form of assessment because they can be automatically graded…and the students can choose an answer at random if they don’t know.The goal of this exercise is to write a function scoreMCQ(attempt, correct), where attempt is a string that contains the answers of the student and correct is a string with the correct answers.The function should return the number of correct answers.Check first that both strings have the same length, otherwise raise an exception.If both strings are empty the score should be 0 of course.To test your code, you can copy paste the following assert statements as your main function:assert(scoreMCQ("","")==0), "First test failed"assert(scoreMCQ("TFTF","TTTT")==2), "Second test failed"assert(scoreMCQ("TTTT","TTTT")==4), "Third test failed"assert(scoreMCQ("CCCC","ABCD")==1), "Fourth test failed"print("All tests succesfull")
Profile the performance of the memoized version of the Fibonacci function defined in Project 6. The function should count the number of recursive calls. State its computational complexity using big-O notation, and justify your answer. The fib function header has been modified to include the counter as the second parameter. Define the Counter class, it should have three methods: __init__, increment, and __str__. When an instance of the Counter class is passed as a parameter, the count property of that instance should be incremented based on the number of recursive calls. The __str__ method should return the count property's value as a string. ----------------------------------------------------------------------------------- """ File: fib.py Project 11.7 Employs memoization to improve the efficiency of recursive Fibonacci.

Write the code in python to define the function has_adjacent_repeats(mystr), which takes a string parameter and returns a boolean result. - If mystr has at least one instance of adjacent characters being equal, return True - Otherwise, return False Hint: You can iterate over the positive indices i for characters in mystr: 1, 2, 3, ...., len(mystr)-1 with a for loop. For each i, if the character at index i matches the character at index i - 1, return True. Otherwise, if no doubled character is found in the entire string, return False. For example: Test Result if not (has_adjacent_repeats("NOODLES") is True): print("error") if not (has_adjacent_repeats("Bananas") is False): print("shwoopsie") if not (has_adjacent_repeats("Hanoverr") is True): print("error")
thanks for answering the first question this is the follow up question b) Now that we have have our data, we need to split this into a training set, and a testing set. But before we split our data into training and testing, we also need to split our data into the predictive features (denoted X) and the response (denoted y). Write a function that will take as input a 2-d numpy array and return four variables in the form of (X_train, y_train), (X_test, y_test), where (X_train, y_train) are the features + response of the training set, and (X-test, y_test) are the features + response of the testing set. Function Specifications: Should take a 2-d numpy array as input. Should split the array such that X is the year, and y is the corresponding population. Should return two tuples of the form (X_train, y_train), (X_test, y_test).
A robot moves in a 2D lattice. The robot can only move north (N), south (S), east (E), and west (W) by a certain number of steps. Assume that the robot always starts at (0,0), and that the x axis is oriented east, while the y axis is oriented north. Write a Python function that, given a set of moves, calculates the final position of the robot. For example, if the set of moves provided as input is: N 2 E 4 S 1 W 3 then the final position of the robot is (1,1). The integer that follows a move is always positive. Follow this code skeleton: def robot_move (moves): X = 0 y = 0 # your code here return (x,y) The moves are provided as an array of tuples. The array can have any number of moves in any order. The example above is passed as input as follows: [('N',2), ('E',4), ('S',1), ('W',3)]
Computer Science C++ please, use Monte Carlo integration to calculate the volume of a d-dimensional hypersphere of radius r = 1. (Note that for d=1, 2, and 3, the common names for d-dimensional volume are length, area, and volume, respectively.) Print out each volume and narrow the answer down to 4 digits with 99% confidence. How far can you push d for this method?
Describe an efficient way of putting a VECTOR representing a deck of n cards into random order in C++. You may use the function randomlnt(n), which returns a random number between 0 and n-1, inclusive. Your method should guarantee that every possible ordering is equally likely. What is the running time of your function?
The Fibonacci sequence begins with O and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the Fibonacci() function, which has an index n as a parameter and returns the nth value in the sequence. Any negative index values should return -1. Ex: If the input is: 7 the output is: Fibonacci (7) is 13 Note: Use a for loop and DO NOT use recursion. 1 #include NM in N 2 3 int Fibonacci(int n) { 4 /* Type your code here. */ 5} 6 7 int main(void) { 8 int startNum; 9 scanf("%d", &startNum); main.c 10 11 printf("Fibonacci (%d) is %d", startNum, Fibonacci (startNum)); return 0; 12 13 14
