(USING MATLAB!) Write a function that will return a random number (float number). If no arguments are passed to the function, it will return one random number from 0 to 1. If one argument is passed, it is the max and the returned one random number will be from 0 to max. If two arguments are passed, they represent the min and max and the function will return one random number within the range of [min, max].

An integer is said to be prime if it’s greater than 1 and divisible only by 1 and itself. For example, 2, 3, 5 and 7 are prime, but 4, 6, 8 and 9 are not. a)  Write a function that determines whether a number is prime. b)  Use this function in a script that determines and prints all the prime numbers between 1 and 10,000. How many of these 10,000 numbers do you really have to test before being sure that you have found all the primes? Display the results in a <textarea>. c)  Initially, you might think that n/2 is the upper limit for which you must test to see whether a number is prime, but you need go only as high as the square root of n. Why? Rewrite the program using the Math.sqrt method to calculate the square root, and run it both ways. Estimate the performance improvement. Please write the code in JavaScript HTML5.

(python) Speed of Sound is a constant 343 m/s Create a function that will return the Frequency Heard based on the above equation.  The function should accept the following parameters: speed of sound, velocity of receiver, velocity of source and frequency of source. Make sure to prompt the user for the input data and call the function. Example Values/Results: Frequency of  Source: 935 HzVelocity of receiver: 24 m/sVelocity of source 43 m/sHeard frequency is 888.977 Hz
