A rocket is launched vertically. At time t= 0, the rocket's engine shuts down. At that time, the rocket has reached an altitude of 500 m and is rising at a velocity of 125 m/s. Gravity then takes over. The height of the rocket as a function of time is 9.8 2+125t+500 for t>0 2 h(t) (a) Create a function called height that accepts time as an input and returns the height of the rocket. Use your function in your solutions to parts b and c. (b) Plot height vs. time for times from 0 to 30 seconds. Use an increment of 0.5 second in your time vector.

***in python only*** use turtle function Define the concentricCircles function such that: It draws a series of concentric circles, where the first parameter specifies the radius of the outermost circle, and the second parameter specifies the number of circles to draw. The third and fourth parameters specify an outer color and an other color, respectively. The outer color is used for the largest (i.e., outermost) circle, and then every other circle out to the edge alternates between that color and the 'other' color. The difference between the radii of subsequent circles is always the same, and this difference is also equal to the radius of the smallest circle. Put another way: the distance between the inside and outside of each ring is the same. Define concentricCircles with 4 parameters Use def to define concentricCircles with 4 parameters Use any kind of loop Within the definition of concentricCircles with 4 parameters, use any kind of loop in at least one place.

Write a function that takes a gross salary and calculates the net salary by deducting: • 7.65% for FICA • x for federal taxes • y for state taxes • z for local taxes Also, deduct $75 for parking fees and $22.50 for a gym membership. The federal tax rate must be between 10 and 37 percent. The state tax rate must be between 3.25 and 11.33 percent. The local tax rate may not be greater than 3%. If any of those values are outside the valid range, return INVALID_PERCENTAGE from your function. Federal, state, local taxes, and gym membership amounts should be passed in by value. FICA and parking should be a global constant. COMPUTER LANGUAGE IN C
Write a function to determine the resultant force vector R of the two forces F₁ and F₂ applied to the bracket, where 0₁ (positive, unit in degree) and ₂ (negative, unit in degree). Write R in terms of unit vector along the and y axis. R must be a vector, for example R = [R₂, R₂]. Note that is expressed in degrees. The coordinate system is shown in the figure below: F2 021 return R # import numpy as np. import math from math import * # Import all the math functions from the math library from numpy import array # Complete the function given the variables F1, F2, thetal (positive, degree), theta2 (negative, degree) and return the value as array #Hints: Use numpy.array to form the force vector and then add the force vectors # Remember to convert the degree to radian in the calculations and be careful of the sign def force_vec (F1, F2, thetal, theta2): R=np.array([0,0]) # Resultant force vector, Initiation of the value # YOUR CODE HERE # Check your answer F1=300 F2=200 0₁ Theta1=60…

6.7 A rocket is launched vertically. At time t= 0, the rocket's engine shuts down. At that time, the rocket has reached an altitude of 500 m and is rising at a velocity of 125 m/s. Gravity then takes over. The height of the rocket as a function of time is h(t) (a) Create a function called height that accepts time as an input and returns the height of the rocket. Use your function in your solutions to parts b and c. 9.8 2 + 125t + 500 for t > 0 (b) Plot height versus time for times from 0 to 30 seconds. Use an incre- ment of 0.5 second in your time vector.

A pandigital number contains all digits (0-9) at least once. Write a function that takes an integer, returning true if the integer is pandigital, and false otherwise. Examples isPandigital (98140723568910) true isPandigital (90864523148909) → false // 7 is missing. isPandigital (112233445566778899) → false
4. You are given the following functions: int functionA(int a) { printf ("a-sd\n", a); if (a==1) return 1; else return functionB (a-1) *2; int functionB (int b) { printf ("b=3d\n",b); if (b--1) return 1; else return functionA (b-1) *3; Write the main function. Your main function should prompt the user for input and then call the mutual recursion by passing in the user's input. The guidelines are described below. int main () { //declare int a to receive user input and int result to receive result of mutual recursion //using a while loop, prompt user for input. The number entered //must be bigger than 1, otherwise repeat user input with an error //message. //call functionA () with int a as input argument. Receive the result in int result. //print result return 0;
Computer Science Write in MIPS a function PAYMENT that takes a number of hours (integer) from $a0 and hourly rate (integer) from $a1. PAYMENT returns the amount of money earned in $v0. Function PAYMENT must use function MYMUL for multiplication. The function MYMUL takes integers from $a2 and $a3 and returns in $v1 their product. You don’t have to implement MYMUL, you just have to use it in your code. You have no idea how MYMUL is implemented. For you, it is just a correct MIPS function that does multiplication as specified. Function PAYMENT should follow all MIPS function calling conventions.
Complete the following TODO by defining a function called add_func(). Define a function called add_func() that takes two arguments. The function should adds the two arguments together using + and return the output. For example, if the input values for the arguments are 1 and 2, then 3 should be returned. Likewise, if the input arguments are "good" and " day", then "good day" should be returned. # TODO print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") todo_check([ (add_func(1,2) == 3,'add_func() did not return 3 when using input values 1 and 2.'), (add_func('good',' day') == "good day",'add_func() did not return "good day" when using input values "good" and " day"') ])
