How many distinguishable ways can the letters of the word millimicron be arranged in order?

soldi70 [24.7K]

total no. of letters = 11

millimicron

dissecting will give us:

no. of m = 2, no. of i = 3, no. of l = 2, no. of c = 1, no. of n =1, no. of r = 1, no. of o = 1

we are going to compute this by using permutation

total no. of ways to arrangement = 11!/ [ 2!* 3! * 2! * 1! *1! *1! *1!]

= 39,916,800/ 24

= 1,663,200 is the answer

zaharov [31]

Answer:

x = -2 ± 452i

Step-by-step explanation:

x² + 4x = 117

x² + 4x - 117 = 0

if you solve this quadratic by using the quadratic formula you get:

x = -2 ± 452i

452i is an imaginary number that equals $\sqrt{-452}$

Identify the values of m and b of the linear function y = mx + b, graphed below.

<h2>Finding the slope and y-intercept of a line given the graph</h2><h3>Answer:</h3>

$b = 4$

$m = -\frac{1}{3}$

<h3>Step-by-step explanation:</h3>

An equation of a line written in its Slope-intercept Form, $y = mx +b$ , has $b$ as its $y$ -intercept and $m$ as its slope.

$b$ or the $y$ -intercept is the $y$ -coordinate when $x = 0$ . On the given line, we can see that when $x = 0$ , $y = 4$ . It's $y$ -intercept is the point $(0,4)$ so $b = 4$ .

The slope, $m$ , of the line can be calculated by $\frac{y_2 -y_1}{x_2 -x_1}\\$ where $x_n$ and $y_n$ is the $xy$ -coordinates of any point $n$ on the line. In the given line, we can see that $(5,3)$ is on the line so this can be point $1$ . $(0,4)$ is also on the line (yes, you can also use the $y$ -intercept in calculating the slope of the line) so this can be our point $2$ .
