A restaurant chain has several store locations in a city (with a name and zip code stored for each), and each is managed by one

manager. Managers manage only one store. Each restaurant location has its own unique set of menus. Most have more than one menu (e.g., lunch and dinner menus). Each menu has many menu items, and items can appear on multiple menus, and with different prices on different menus. Represent this situation of restaurants with an E-R diagram.

Define a function called 'findWordFreq, which takes two parameters. The first parameter, 'text" is an nltk.text.Text object and
MakcuM [25]

Answer:

import os

import nltk

import zipfile

from nltk. corpus import gutenberg

from nltk. text import Text

def findWordFreq(text, word):

   textfreq = nltk. FreqDist(text)

   wordfreq = nltk.FreqDist(word)

   maxfreq = max(textfreq)

   return wordfreq, maxfreq

if -_name__ == '__main__':

   text = input()

   word = input()

   if not os.path.exists(os.getcwd() + "/nltk_data"):

       with zipfile.ZipFile("nltk_data.zip", 'r') as zip_ref:

           zip_ref.extractall(os.getcwd())

   os.environ['NLTK_DATA'] = os.getcwd() + "/nltk_data"

   text = Text(gutenberg.words (text))

   word_freq, max_freq = findWordFreq(text, word)

   print(word_freq)

   print(max_freq)

Explanation:

The natural language package in python is used to get and analyse word from voice input. The python code above get words from a zipfile extract, and the 'findWordFreq' function gets the word count and the maximum number of alphabet used in the word distribution.

What is a limitation of 5G mmWave, despite its high speed?
Allushta [10]

The limitation of 5G mmWave, despite its high speed, is the fact that they have a short range.

  • 5G simply means the fifth generation of wireless technology that has great speed and provides connectivity to cellphones.

  • mmWave is the higher frequency radio band that is very fast. It should be noted that the 5G mmWave is super fast and is being used by large organizations to improve their work.

  • The main limitation of 5G mmWave is that for one to use it, one has to be close to the 5G tower. This is why it's hard for people living in rural areas to benefit from it unless it's situated close to them.

  • It should be noted that despite the fact 5G offers greater bandwidth, which is vital in relieving network congestion, there are still more improvements to be made in order for everyone to benefit.

In conclusion, the limitation of 5G mmWave, is that they have a short range.

What is the initial condition in this set of code?
marissa [1.9K]

Answer:An initial condition is an extra bit of information about a differential equation that tells you the value of the function at a particular point. Differential equations with initial conditions are commonly called initial value problems.

The video above uses the example

{

d

y

d

x

=

cos

(

x

)

y

(

0

)

=

−

1

to illustrate a simple initial value problem. Solving the differential equation without the initial condition gives you  

y

=

sin

(

x

)

+

C

.

Once you get the general solution, you can use the initial value to find a particular solution which satisfies the problem. In this case, plugging in  

0

for  

x

and  

−

1

for  

y

gives us  

−

1

=

C

, meaning that the particular solution must be  

y

=

sin

(

x

)

−

1

.

So the general way to solve initial value problems is: - First, find the general solution while ignoring the initial condition. - Then, use the initial condition to plug in values and find a particular solution.

Two additional things to keep in mind: First, the initial value doesn't necessarily have to just be  

y

-values. Higher-order equations might have an initial value for both  

y

and  

y

′

, for example.

Second, an initial value problem doesn't always have a unique solution. It's possible for an initial value problem to have multiple solutions, or even no solution at all.
