Answer:

Step-by-step explanation:

Factorial is applicable only for natural numbers and 0.

0! =1 trivially.

FOr other numbers, factorial is defined as 1x2x...n

For example 1! = 1

2! = 1x2 = 2

and so on.

i.e. n! = product of all natural numbers from 1 to n

= 1x2x....n

Using the above

we have n =4

Natural numbers from 1 to 4 are 1,2,3,4

Find the product of these 4 natural numbers to get 4!

4! = 1x2x3x4 = 24

I'm assuming that the number after the variable is supposed to be the exponent.

$5x^{5}+8 x^{2} +2x-3x^{9}-8x^{4}-4x^{5}$

Combine like terms to get:

$-3x^{9}+x^{5}-8x^{4}+8x^{2}+2x$

Hence the answer is 480ml

Step-by-step explanation:

Given Elena wonders how much water it will take to fill her cup. She drops her pencil in the cup and notice it just fit diagonally. The pencil is 17cm long (hypotenes) and the cup is 15cm tall.

To find how much water it can hold

SOLUTION

$\sqrt{x {} ^{ 2} + x {}^{2} + 15 {}^{2} = 17 }$
