What is 6P4<br> permutations and combinations
labwork [276]

Answer:

360

Step-by-step explanation:

Here we are required to find _^{6}\textrm{P}_{4}

It is a problem of Permutation and we must understand the formula for finding permutations.

The general formula for finding the permutation is given as below:

_^{m}\textrm{P}_{n}=\frac{m!}{(m-n)!}

Hence

_^{6}\textrm{P}_{4}=\frac{6!}{(6-4)!}

_^{6}\textrm{P}_{4}=\frac{6!}{2!}

Where

m!=m\times(m-1)\times\(m-2)\times\cdot\cdot\cdot\codt\cdot3\times2\times1

6!=6\times5\times4\times3\times2\times1

2!=2\times1

Hence

_^{6}\textrm{P}_{4}=\frac{6\times5\times4\times3\times2\times1}{2\times1}

_^{6}\textrm{P}_{4}=6\times5\times4\times3

_^{6}\textrm{P}_{4}=360

Yuri [45]

Answer:  y = 12.50x + 45

Step-by-step explanation:

if x is the number of hours  and you pay $12.50 per hour then we can come up the expression 12.50x

You will be charge $45 as an initial fee so it will be 12.50x + 45 and that has to equal the total cost which is y.

y = 12.50x + 45

If using the method of completing the square to solve the quadratic equation x2 + 3x - 17 = 0, which number would have to be add
MatroZZZ [7]

Answer:

Step-by-step explanation:

To solve using completing square, we need to write the equation as x2+3x=17.

The next step is to add a number such that the square can be completed. The number must be equal to (b/2a)^2, so here it will be (3/2)^2 = 9/4

The equation then becomes x2+3x+(9/4)=17+(9/4).

Solving it further will get you the final answer
