How many permutations can be made with the letters in the word Metallica
pentagon [3]
<h3>Answer:   90720 </h3>

===============================================

Explanation:

There are 9 letters in "Metallica", so there would be 9! = 9*8*7*6*5*4*3*2*1 = 362880 different permutations; however, this is only the case if we could tell the letters L and A apart.

We have two copies of each of those repeated letters, so we have to divide by 2!*2! = (2*1)*(2*1) = 4 to account for these repeats.

Because we can't tell the repeated letters apart, we really have (9!)/(2!*2!) = (362880)/(4) = 90720 different permutations.

What is the approximate distance between the points (1,-2) and (-9,3) on a coordinate grid
jeka57 [31]

<u>Answer</u>

5\sqrt{5} ≈ 11.1803398874989485


<u>Detailed Explanation </u>


We will be using the distance formula for this problem


\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}


Now, let's input the numbers into the formula.


\sqrt{\left(-9-1\right)^2+\left(3-\left(-2\right)\right)^2}


Solve.


Therefore, the distance between the two points is

5\sqrt{5} ≈ 11.1803398874989485
