Step-by-step answer

P Answered by Specialist

Never true

Simple concept see below :

Given :-

$\dashrightarrow \sf ab = a$

$\\$

divide both side by a

$\dashrightarrow \sf \dfrac{ab}{a} = \dfrac{a}{a}$

$\\$

$\dashrightarrow \sf \dfrac{\cancel ab}{\cancel a} = \dfrac{a}{a}$

$\\$

$\dashrightarrow \sf \dfrac{b}{1} = \dfrac{a}{a}$

$\\$

$\dashrightarrow \sf b = \dfrac{a}{a}$

$\\$

$\dashrightarrow \sf b = \cancel\dfrac{a}{a}$

$\\$

$\dashrightarrow \sf b = \dfrac{1}{1}$

$\\$

$\dashrightarrow \bf b =1$

So here given b = 3

but it's clearly visible that b = 1

.°. b ≠ 3

therefore it's never true

In if statement, the result will be false if the hypothesis is true but the conclusion is false. Other combination will result in true.
Most of the statement will be always or never. Sometimes statement more frequently found in a problem with a case, not in a problem with an equation like this.
1:
p is true
q is true,
then ~ p --> ~ q
false --> false
is always true.

a: always
The result of the logical statement is true. So, it will always be true.

2:
p is true
~ q is false,
then p --> ~ q
true --> true
is never false.

b: never
The result of the logical statement is true. So, it will never be false.

3: If
p is true
q is false,
then p --> q
true-->false
is never true.

c: never
The result of the logical statement is false. So, it will never be true.

4:
p is false
q is true,
then p or q
false or true
is always true.

a: always
When using or statement, you only need 1 true statement to get a result as true.

5: If
p --> q is true
q is true,
then p is true.

b: always
The value of p will always true because if the value of p is false there is no chance that p-->q would result in true.
The answer will be different if q=false because in this case p=false still giving true result.

Read the diary entries. Nicholas’s Diary: April 2 and 3 Friday, April 2 Well, it’s only 10 more hours until my father and I leave for our treasure hunt. Every Saturday morning for as long as I can remember I have seen him leave, always by himself, to look for treasure. I have always longed to go with him, and he’s always told me that someday I would get the chance. I was so excited when he told me I would finally have my chance that I was bouncing off the walls like a rubber ball and springing from one place to the next the rest of the day. He

Answer:

Poem with highlighted words given below:

Step-by-step explanation:

It is another excuse for a party,

a tame affair with pizzas and Ping-Pong.

For the first time, he has said no.

The Bengali celebration, held on the closest Saturday,

forty guests, dazzling saris,

a group of men starting a poker game.

Gogol is the oldest child,

but he and Moushumi have nothing to say.

She reads Pride and Prejudice,

while the children watch TV.

Presents are opened, dictionaries, calculators,

ugly sweaters, and more.

His father gives him a book,

The Short Stories of Nikolai Gogol.

Gogol examines the picture,

relieved to see no resemblance.

He hates questions about his name,

hates having to explain.

His name is both absurd and obscure,

neither Indian nor American.

He wishes he could disguise it,

shorten it somehow.

He dislikes being Gogol,

his father's favorite author.

He wishes he had been named Nikhil,

but it's too late now.

Gogol hates his name,

its irrelevance and weight.

But his father feels a kinship,

a special connection with Gogol.

He keeps the explanation to himself,

a silent secret. G

ogol locks the door,

settles down with his lyrics.

And he realizes,

Gogol isn't his first name.

It's Nikolai,

a last name turned first name.
