Find the missing number. 1, 2, 6, 24, 120,?

1 answer:

8 0

The answer is A. Each time it is multiplied by a higher number so 1 x 2 = 2 . 2 x 3 = 6 . 6 x 4 = 24 . 24 x 5 = 120 . 120 x 6 = 720

Suppose that the functions p and q are defined as follows.

inessss [21]

The most appropriate choice for function can be given by

q $o$ p(3) = $\sqrt{15}+1$

p $o$ q(3) = $2\sqrt{3} + 10$

What is function?

A function from A to B is a rule that maps to each element of A a unique element of B.

A is called the domain of the function and B is called the co domain of the function.

We can do addition, subtraction, multiplication, division and composition on functions.

Let f and g be two functions

f $o$ g(x) = f(g(x)) and g $o$ f(x) = g(f(x))

This is known as composition of function.

Here,

$p(x) = x^2 + 6\\q(x) = \sqrt{x} +1$

q $o$ p(x) = q(p(x))

= $q(x^2+6)$

= $\sqrt{x^2+6}+1$

q $o$ p(3) = $\sqrt{3^2+6}+1$

= $\sqrt{15}+1$

p $o$ q(x) = p(q(x))

= p( $\sqrt{x}+1$ )

= $(\sqrt{x}+1)^2+6$

= $x + 1 + 2\sqrt{x} + 6$

= $x + 2\sqrt{x} +7$

p $o$ q(3) = $3 + 2\sqrt{3} +7$

$2\sqrt{3} + 10$

Identified the two consecutive integers in which each square root lies between.

belka [17]

1- $\sqrt{156}$

156 lies between 144 and 169

So $\sqrt{156}$ lies between 12 and 13.

2- $\sqrt{320}$

320 lies between 289 and 324.

So $\sqrt{320}$ lies between 17 and 18.

3- $\sqrt{249}$

249 lies between 225 and 256

So $\sqrt{249}$ lies between 15 and 16.

Answer:

Option C is incorrect.

Step-by-step explanation:

An infinite series is given by m + b, 2m + b, 3m + b, 4m + b, ... .

A) The above sequence is given by f(x) = mx + b for x = {1, 2, 3, ......}

For, x = 1, f(x) = m + b

For, x = 2, f(x) = 2m + b

.............

So, this is a valid definition of the above sequence.

B) The above sequence is given by f(x) = 2m + b + m(x - 2) for x = {1, 2, 3, ......}

For, x = 1, f(x) = 2m + b - m = m + b

For, x = 2, f(x) = 2m + b + 0 = 2m + b

.............

So, this is a valid definition of the above sequence.

C) The above sequence is given by $a_{n} = m - b + m(n - 1)$ for n = {1, 2, 3, ......}

For, n = 1, $a_{1} = m - b + m(1 - 1) = m - b$

For, n = 2, $a_{2} = m - b + m(2 - 1) = 2m - b$

.............

So, this is not a valid definition of the above sequence.

D) The above sequence is given by $a_{1} = m + b$ and $a_{n + 1} = a_{n} + m$ for n = {1, 2, 3, .........}

For, n = 1, $a_{1} = m + b$

For, n = 2, $a_{2} = a_{1} + m = (m + b) + m = 2m + b$

.............

So, this is a valid definition of the above sequence.

Therefore, option C is incorrect. (Answer)
