Modems create an analog signal that carries digital data on it,
and strip the digital data from an analog signal that they receive. 
That's what's needed to connect through the telephone system,
since the telephone system is still one big analog system.

Answer:

Following are the program in Python langauge

person_name = input() # Read the person name by the user

person_age=0  #declared a vaiable person_age  

person_age = int(input()) # read person_age by the user

person_age=person_age+5  # add 5 to person_age

print('In 5 years',person_name,'will be',person_age) # display the output

Output:

  Amy

   4

   In 5 years Amy will be 9

Explanation :

Following is the description of code:

  • Read the value of the "person_name" variable by the user by using the input function.
  • Declared a variable person_age and initialized 0 with them.
  • Read the value of "person_age" variable by user by using input function and convert into int by using int function
  • Add 5 to "person_age" variable and store again them into the "person_age" variable.
  • Finally, display the output which is mention in the question.

The molecule 2,2-diisopropylheptane is incorrectly named. what is the correct name?
pentagon [3]
Isopropyl is: CH3 - CH - CH3
                                |

Heptane is: CH3 - CH2 - CH2 - CH2 - CH2 - CH2 - CH3

Then 2,2 isopropyl heptane is:

CH3 - CH - CH3
           |
CH3 - C - CH2 - CH2 - CH2 - CH2 - CH3
           |
CH3 - CH - CH3.

There you can count that the longest carbon chain has 8 carbon atoms.
So the right name is of an octane.

I will rearrange the chain to show the 8 carbon chain in a row:

           CH3   CH3
           |          |
CH3 - CH -   C - CH2 - CH2 - CH2 - CH2 - CH3
                      |
           CH3 - CH - CH3

Now, you can see that the right name is 3 isopropyl - 2, 3 dimethyl octane

Write three functions in C/C++: one that declares a large array statically, one that declares the same large array on the stack,
Nikolay [14]

Answer:

See explaination

Explanation:

#include<iostream>

#include<stack>

#include <algorithm> // std::make_heap, std::pop_heap, std::push_heap, std::sort_heap

#include <vector> // std::vector

using namespace std;

void StaticArray()

{

unsigned int array[64536];

for(unsigned int i=0;i<64536;i++)

array[i]=i;

}

void Stack()

{

stack<unsigned int> mystack;

for(unsigned int i=0;i<64536;i++)

mystack.push(i);

}

void Heap()

{

unsigned int myints[64536];

for(unsigned int i=0;i<64536;i++)

myints[i]=i;

vector<unsigned int> v(myints,myints+64535);

make_heap (v.begin(),v.end());

push_heap (v.begin(),v.end());

}

int main()

{

StaticArray();

Stack();

Heap();

return 0;

}

Prove that f(n) = 20n3 + 10nlogn + 5 is O(n3)
sp2606 [1]

Answer:

The proof is in the explanation

Explanation:

f(n) is O(n^{3}) if f(n) \leq cn^{3} for n \geq n_{0}.

So, basically, we have to solve the following inequality

f(n) \leq cn^{3}

20n^{3} + 10n\log{n} + 5 \leq cn^{3}

Dividing everything by n^{3} to simplify, we have

20 + \frac{10\log{n}}{n^{2}} + \frac{5}{n^{3}} \leq cn^{3}

I am going to use n = n_{0} = 1. So

20 + 5 \leq c

c \geq 25

There is a solution for the inequality, which proves that f(n) = 20n^{3} + 10n\log{n} + 5 is O(n^{3})
