In a spreadsheet what does the following symbol mean?
$
Answer:
$ = dollar sign
Explanation:
In a spreadsheet, the $ symbol is the symbol of the dollar. The dollar is the currency of the United States.
What is currency?Currency is a form of payment for goods and services. In a nutshell, it is money in the form of paper and coins that is usually issued by a government and is generally accepted as a form of payment at face value.
Currency exchange rates differ between businesses because each one distorts the interbank rate to maximize profits. We encounter numerous competitors who post interbank rates internet as bait to attract new customers, but once the customers are onboard, they drastically change the rate, typically not in the customers' favor.
Therefore, the $ symbol represents the dollar in a spreadsheet. The US dollar is the country's currency.

New cars use embedded computers to make driving safer. The given statement is true.
What is RAM?
The word RAM stands for random-access memory and it is known as memory of short term where data is stored and as required by the processor. This is not there to deal with long term data and it is working after the computer turned off.
Generally, there are three types of RAM and these are SRAM, ECC, and DRAM. The SRAM stands for static random memory, and DRAM stands for dynamic access memory.
CPU stands for central processing unit and commonly it is known as brain of the computer, the main function of CPU is to control the function of the computer or system and it gives command to the parts of computer.
Therefore, New cars use embedded computers to make driving safer. The given statement is true.

In numerical methods, one source of error occurs when we use an approximation for a mathematical expression that would otherwise be too costly to compute in terms of run-time or memory resources. One routine example is the approximation of infinite series by a finite series that mostly captures the important behavior of the infinite series.
In this problem you will implement an approximation to the exp(x) as represented by the following infinite series,
exp(x) = Infinity n= 0 xn/xn!
Your approximation will be a truncated finite series with N + 1 terms,
exp(x, N) = Infinityn n = 0 xn/xn!
For the first part of this problem, you are given a random real number x and will investigate how well a finite series expansion for exp(x) approximates the infinite series.
Compute exp(x) using a finite series approximation with N E [0, 9] N (i.e. is an integer).
Save the 10 floating point values from your approximation in a numpy array named exp_approx. exp_approx should be of shape (10,) and should be ordered with increasing N (i.e. the first entry of exp_approx should correspond to exp(x, N) when N = 0 and the last entry when N = 9).
Answer:
The function in Python is as follows:
import math
import numpy as np
def exp(x):
mylist = []
for n in range(10):
num = (x**n)/(math.factorial(n))
mylist.append([num])
exp_approx = np.asarray(mylist)
sum = 0
for num in exp_approx:
sum+=num
return sum
Explanation:
The imports the python math module
import math
The imports the python numpy module
import numpy as np
The function begins here
def exp(x):
This creates an empty list
mylist = []
This iterates from 0 to 9
for n in range(10):
This calculates each term of the series
num = (x**n)/(math.factorial(n))
This appends the term to list, mylist
mylist.append([num])
This appends all elements of mylist to numpy array, exp_approx
exp_approx = np.asarray(mylist)
This initializes the sum of the series to 0
sum = 0
This iterates through exp_approx
for num in exp_approx:
This adds all terms of the series
sum+=num
This returns the calculated sum
return sum
Davos has been reading about encryption recently. He begins to wonder how anything can be secure if everyone is using the same set of algorithms. After all, anyone using the same algorithm would be able to decrypt anything that had been encrypted using that algorithm. Which of the following helps make the data unusable by anyone else using that same encryption scheme without having this information?
a. Algorithm
b. Cipher
c. Key
d. Block
Answer:
The correct answer is B. Cipher.
Explanation:
Cipher is a system of reversible transformations that depends on some secret parameter, called key, and is designed to ensure the secrecy of transmitted information.
The cipher can be a combination of conventional characters or an algorithm for converting ordinary numbers and letters. The process of making a message secret with a cipher is called encryption. An important parameter of any cipher is the key - a parameter of the cryptographic algorithm, which ensures the selection of one transformation from the set of transformations possible for this algorithm. In modern cryptography, it is assumed that all the secrecy of a cryptographic algorithm is concentrated in the key.
Write an interface called Shape, inside, there is a method double area(); write a class called Box which implements the Shape. In Box, there are two data members: a double called length, and a double called width. Also implements constructor, and the method area() which calculates the area by multiplying the length and width. Then write a Tester class, which has a main method and creates a box object and displays the area.
Answer:
Explanation:
The following code is written in Java. It contains the interface Shape, the class Box, and a tester class called Brainly with the main method. Box implements the Shape interface and contains, the instance variables, the constructor which takes in the inputs for length and width, getter methods for length and width, and the defines the area() method from the interface. Then the object is created within the Brainly tester class' main method and the area() method is called on that object. Output can be seen in the image attached below. Due to technical difficulties, I have added the code as a txt file below.

Suppose that a minus sign in the input indicates pop the stack and write the return value to standard output, and any other string indicates push the string onto the stack. Further suppose that following input is processed:
this parrot - wouldn't voom - if i put -- four thousand --- volts - through it -
What are the contents (top to bottom) left on the stack?
a. through wouldn't this.
b. this wouldn't through.
c. it through wouldn't.
d. it through volta.
e. volts through it.
Answer:
e. volts through it
Explanation:
volts through it
The contents (top to bottom) left on the stack is volts through it. Thus, option E is correct.
What is standard output?When a computer program begins execution, standard streams are interconnected input and output channels of communication between the program and its surroundings. The three I/O connections are known as standard input (stdin), standard output (stdout), and standard error (stderr).
A negative sign in the input indicates that the stack should be popped, and the return value should be sent to standard output, whereas any other string means that the string should be pushed into the stack. Assume that the following input is processed: this parrot would not voom if I pushed — four thousand —- volts - through it.
The contents of the stack (from top to bottom) are volts via it. As a result, option E is correct.

The project downloaded contains a package (folder) named Q1 within the src folder. Inside Q1 is a Java class named Questions. The purpose of Question 1 is to examine your understanding of loops and branching conditions. You should implement all of your code for this question in the main method of the Questioni class. While significant detail is provided below to be sure you undertand what is required, please note that the amount of code required to solve this question (Parts a-c) is less than 10 lines (total). In the Question1 class, you are given a line of code that generates a random number between 0 and 1. Math.random(): //generates number between 0 and 1 val
You are to create a loop which, in each iteration, generates a new random value, assigns it to val using the line provided and checks to see if that val is greater than 0.5. If val is greater than 0.5, a variable named counter should be incremented. The loop should continue this process (generate random value, check if it is greater than 0.5) until a total of three random numbers generated are greater than 0.5 (values do not have to be consecutive). You should also use the variable named numIterations, which is included for you, to track how many iterations of your loop were required for you to generate three random numbers greater than 0.5. A printin() statement is included for you that displays the value of numlterations. As an example of how the program should behave, if the following sequence of random numbers are randomly generated from your loop
0.3, 0.7,0.2, 0.6,0.9
then numIterations would equal 5 (the third value greater than 0.5 occured on the fifth iteration).
If
0.6, 0.8, 0.75
was the random sequence of numbers generated by your loop, then numlterations would equal 3 (the third value greater than 0.5 occured on the third iteration).
These are two examples to illustrate the scenario given in Question 1. Since at each iteration of your loop the number generated is random, the value of numIterations that your program observes may be any value greater than or equal to 3. Note that your program does not need to print out each of the random values that it generates. The steps to solve Question 2 are broken down as follows.
a. Implement a branching condition that increases the variable counter by 1 if val is larger than 0.5 1
b. Add a loop around the code created in Part a that continues until counter equals 3.
c. Use the variable numlterations to count how many times your loop iterates.

Write a test program that prompts the user to enter the number of the items and weight for each item and the weight capacity of the bag, and displays the maximum total weight of the items that can be placed in the bag. Here is a sample run:
Answer:
The program in Python is as follows:
n = int(input("Number of weights: "))
weights= []
for i in range(n):
inp = float(input("Weight: "))
weights.append(inp)
capacity = float(input("Capacity: "))
possible_weights = []
for i in range(n):
for j in range(i,n):
if capacity >= weights[i] + weights[j]:
possible_weights.append(weights[i] + weights[j])
print("Maximum capacity is: ",max(possible_weights))
Explanation:
This gets the number of weights from the user
n = int(input("Number of weights: "))
This initializes the weights (as a list)
weights= []
This iteration gets all weights from the user
for i in range(n):
inp = float(input("Weight: "))
weights.append(inp)
This gets the weight capacity
capacity = float(input("Capacity: "))
This initializes the possible weights capacity (as a list)
possible_weights = []
This iterates through the weights list
for i in range(n):
for j in range(i,n):
This gets all possible weights that can be carried by the bag
if capacity >= weights[i] + weights[j]:
possible_weights.append(weights[i] + weights[j])
This prints the maximum of all possible weights
print("Maximum capacity is: ",max(possible_weights))
Rideshare companies like Uber or Lyft track the x,y coordinates of drivers and customers on a map. If a customer requests a ride, the company's app estimates the minutes until the nearest driver can arrive. Write a method that, given the x and y coordinates of a customer and the three nearest drivers, returns the estimated pickup time. Assume drivers can only drive in the x or y directions (not diagonal), and each mile takes 3.5 minutes to drive. All values are doubles; the coordinates of the user and of the drivers are stored as arrays of length 2. 289222.1780078.qx3zqy7
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static void main (String[]args){
Scanner input = new Scanner(System.in);
double user[] = new double[2]; double dr1[] = new double[2];
double dr2[] = new double[2]; double dr3[] = new double[2];
System.out.print("Enter user coordinates: ");
for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }
System.out.print("Enter driver 1 coordinates: ");
for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }
System.out.print("Enter driver 2 coordinates: ");
for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }
System.out.print("Enter driver 3 coordinates: ");
for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }
double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);
double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);
double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);
System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");
System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");
System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");
}
}
Explanation:
The following array declarations are for the customer and the three drivers
double user[] = new double[2]; double dr1[] = new double[2];
double dr2[] = new double[2]; double dr3[] = new double[2];
This prompts the user for the customer's coordinates
System.out.print("Enter user coordinates: ");
This gets the customer's coordinate
for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }
This prompts the user for the driver 1 coordinates
System.out.print("Enter driver 1 coordinates: ");
This gets the driver 1's coordinate
for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }
This prompts the user for the driver 2 coordinates
System.out.print("Enter driver 2 coordinates: ");
This gets the driver 2's coordinate
for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }
This prompts the user for the driver 3 coordinates
System.out.print("Enter driver 3 coordinates: ");
This gets the driver 3's coordinate
for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }
This calculates the distance between driver 1 and the customer
double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);
This calculates the distance between driver 2 and the customer
double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);
This calculates the distance between driver 3 and the customer
double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);
The following print statements print the estimated pickup time of each driver
System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");
System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");
System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");
