Answer:

True

Explanation:

If s=abcd is a string defined over {a,b,c,d}, it corresponds to a regular expression which can be represented using a finite automata. Then the reverse of the string essentially corresponds to another finite automata where the starting state becomes the accepting state and vice versa.Moreover all the directions of state transitions will be reversed for each of the transitions in the original automata.

With these modifications, the new finite automata will accept a string which is reverse of the original string ,namely, dcba and this string will ne part of the reverse language.

Write c++ program bmi.cpp that asks the user bmi.cpp the weight (in kilograms) and height (in meters).

Galina-37 [17]

Answer:

// here is code in C++(bmi.cpp).

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

float weight,height;

cout<<"enter the weight(in kilograms):";

//read the weight

cin>>weight;

cout<<"enter the height(in meters):";

//read the height

cin>>height;

// calculate the bmi

float bmi=weight/(pow(height,2));

// print the body-mass index with two decimal places

cout<<"BMI is: "<<fixed<<setprecision(2)<<bmi<<endl;

return 0;

}

Explanation:

Read the weight from user and assign it to variable "weight",read height and assign it to variable "height".Then find the body-mass index as (weight/height^2).Here weight should be in kilograms and height should be in meters.

Output:

enter the weight(in kilograms):75

enter the height(in meters):1.8

BMI is: 23.15

Levart [38]

R markdown notebook describes a notebook format in R programming which supports R programmers to run codes while also writing documents or explanation alongside. Hence, the missing option is Dashboard.

R markdown may be compared to jupyter notebooks which also supports writing in markdown language.

The R markdown notebooks can be created using the R studio, which allows the conversion notebooks of these notebooks into several different formats including the creation of dashboards.

Hence, R markdown notebooks can be converted to HTML PDF, word document, slide presentation and dashboards.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:

sdas [7]

Answer:

The modified program in Python is as follows:

import math

paint_colors = {'red': 35,'blue': 25,'green': 23}

wall_height = int(input('Enter wall height (feet):\n'))

wall_width = int(input('Enter wall width (feet):\n'))

area = wall_height*wall_width

print('Wall area:',area,'square feet')

paint_needed = area/350.0

print('Paint needed: {:.2f} gallons'.format(paint_needed))

print('Cans needed:',round(paint_needed),'can(s)')

color = input("Choose a color to paint the wall: ")

print("Cost of purchasing", color, "paint: $",paint_colors[color])

Explanation:

The italicized are given from the question [unchanged]

import math

paint_colors = {'red': 35,'blue': 25,'green': 23}

wall_height = int(input('Enter wall height (feet):\n'))

This gets input for width

wall_width = int(input('Enter wall width (feet):\n'))

Calculate the wall area

area = wall_height*wall_width

Print the calculated wall area

print('Wall area:',area,'square feet')

Calculate the amount of paint needed

paint_needed = area/350.0

Print the amount of paint needed to 2 decimal places

print('Paint needed: {:.2f} gallons'.format(paint_needed))

Print the amount of can needed to nearest integer

print('Cans needed:',round(paint_needed),'can(s)')

Prompt user for color of paint [here, we assume the user input is correct]

color = input("Choose a color to paint the wall: ")

Prints the corresponding amount for the color

print("Cost of purchasing", color, "paint: $",paint_colors[color])
