The value of $^6P_6$ is 720

<h3>How to solve the expression?</h3>

The expression is given as:

$^6P_6$

The permutation formula is:

$^nP_r = \frac{n!}{(n - r)!}$

So, we have:

$^nP_r = \frac{6!}{(6 - 6)!}$

Evaluate the difference

$^nP_r = \frac{6!}{0!}$

0! = 1.

So, we have:

$^nP_r = 6!$

Evaluate the factorial

$^6P_6 = 720$

Hence, the value of $^6P_6$ is 720

PLEASE HELP The volume of a cube is defined by the function, V(x), where the volume is measured in cubic meters. Find a polynomi

olya-2409 [2.1K]

we have

$V(x)=x^3-12x^2+48x-64$

we know that

The volume of a cube is equal to

$V=b^{3}$

where

b is the length side of a cube

Using a graph tool------> find the roots of the polynomial

see the attached figure

x=4

$x^3-12x^2+48x-64=(x-4)^{3}$

therefore

<u>The answer is</u>

the length side of a cube is equal to (x-4)

grin007 [14]

Answer:

it would help her know how to prepare her teaching to match the students learning and expectations

Step-by-step explanation:

This idea of opening this tutoring service for students in these grades would prove a success if if martine has adequate knowledge of her students/customers. That is the learners requirements, their expectations, their experiences, and their strengths and weaknesses in particular subject areas.

Knowledge of these expectations would help to set Martine on the path of tutoring success and this would attract more students.

Simplified?

Answer:

Option B

Step-by-step explanation:

Given the following question:

In order to find the answer, we need to convert the scientific notation into standard notation and then simplify by subtracting the decimals. Then we convert the standard notation back into scientific notation.

$0.0007 - (4.9\times 10^{-7} )$
$4.9\times10^{-7} =0.00000049$
$0.0007-0.00000049$
$0.0007-0.00000049=0.00069951$
$=0.00069951$
$0.00069951=6.9951 \times10^{-7}$
$=6.9951 \times10^{-7}$

Your answer is "6.9951 × 10^-7" or option B.

Hope this helps.
