<u>Answer:</u>

The value of f(x) = 2x^2 + 1 when x=3 is 19, hence the correct option is ‘d’.

<u>Solution:</u>

A two degree polynomial equation is given in the question.

The equation is:

F(x)=2 x^{2}+1

We need <em>to find the value of f(x) when the value of x is 3. </em>

To solve a question like this we have to substitute the given value of x in the given equation and then simplify it.

Now let's substitute the value of x in the given equation.

F(x)=2(3)^{2}+1

First we square the number 3 and then multiply it with 2 and then add 1.

This is done because of the BODMAS rule, in which multiplication is given higher preference as compared to addition.

On solving the equation we get,

F(x)=2×9+1

F(x)=18+1

F(x)=19.

Therefore the value of f(x) when x=3 is 19.

Hence the correct option is ‘d’.

hram777 [196]

Solve 10x = 4.1 for x.  Divide both sides of this equation by 10:  x = 4.1 / 10.

x = 0.41

Step 3: Now multiply the values to get 14,918,904,000. That is almost 15 billion passwords.
Troyanec [42]

The number of passwords that would be allowed if users were allowed to reuse the letters and numbers is 30891577600

<h3>How to determine the number of passwords</h3>

The given parameters are:

Password length = 8

Letters = 6

Numbers = 2

There are 26 letters and 10 digits.

Since the letters and the numbers can be repeated, then the number of passwords is:

Count = 26^6 * 10^2

Evaluate

Count = 30891577600

Hence, the number of passwords that would be allowed if users were allowed to reuse the letters and numbers is 30891577600
