Answer:

import math

angle = float(input('Enter Angle: '))

shadowLength = float5(input('Enter Shadow Length: '))

tree_height = math.tan(angle)*shadowLength

print('Tree Height = {}'.format(tree_height))

Explanation:

From the equation given, the first step is to derive the equation for calculating the Tree Height.

$tan(angleElevation) = tree height / shadow length\\\\tree height = tan(angleElevation) * shadow length$

In order to calculate the tangent of an angle, the math module has to be imported. math module allows the program to perform advanced math operations.

The program then prompts the user to input values for angle and shadow length.

The inputted values are converted to floats and used in the equation that was derived for Tree height.

Three height is evaluated and the result is printed to the screen

Write a function listLengthOfAllWords which takes in an array of words (strings), and returns an array of numbers representing t

vesna_86 [32]

Answer:

public static int[] listLengthOfAllWords(String [] wordArray){

int[] intArray = new int[wordArray.length];

for (int i=0; i<intArray.length; i++){

int lenOfWord = wordArray[i].length();

intArray[i]=lenOfWord;

}

return intArray;

}

Explanation:

Declare the method to return an array of ints and accept an array of string as a parameter
within the method declare an array of integers with same length as the string array received as a parameter.
Iterate using for loop over the array of string and extract the length of each word using this statement int lenOfWord = wordArray[i].length();
Assign the length of each word in the String array to the new Integer array with this statement intArray[i]=lenOfWord;
Return the Integer Array

A Complete Java program with a call to the method is given below

import java.util.Arrays;

import java.util.Scanner;

public class ANot {

public static void main(String[] args) {

String []wordArray = {"John", "James", "David", "Peter", "Davidson"};

System.out.println(Arrays.toString(listLengthOfAllWords(wordArray)));

}

public static int[] listLengthOfAllWords(String [] wordArray){

int[] intArray = new int[wordArray.length];

for (int i=0; i<wordArray.length; i++){

int lenOfWord = wordArray[i].length();

intArray[i]=lenOfWord;

}

return intArray;

}

}

This program gives the following array as output: [4, 5, 5, 5, 8]

An organization’s IRP prioritizes containment over eradication. An incident has been discovered where an attacker outside of the

emmasim [6.3K]

Answer:

The correct answer is (a) Remove the affected servers from the network.

Explanation:

Solution:

Now, since the organisation top priority is more of containment over eradication, an outbreak code that is hostile as an can be suppressed effectively by removing the web server completely from the over all network facilities or infrastructure.

Also, if the affected servers are not removed, it might affect the integrity, confidentiality of sensitive materials or documents which will be exposed to the outside world by the attacker.
