Laura has a backyard that she wants to renovate. Her

miskamm [114]

Answer:

Area of the walkway = 8<em>x </em>+ 24

Step-by-step explanation:

Area of the total backyard = $l\times b$

Area of total backyard = $(x+6)\times (x+4) = x^{2} +10x + 24$

Now, Area of the rectangular garden = $l\times b$

Area of the rectangular garden = $x (x+2) = x^{2} + 2x$

Now area of the walkway poured with concrete = Area of the backyard - Area of the rectangular garden

= $(x^{2} +10x +24) - (x^{2} +2x)$

= $x^{2} + 10x +24 - x^{2} -2x$

= 8<em>x</em> + 24

Find out the number of combinations and the number of permutations for 8 objects taken 6 at a time. Express your answer in exact

umka2103 [35]

Solution:

The permutation formula is expressed as

$\begin{gathered} P^n_r=\frac{n!}{(n-r)!} \\ \end{gathered}$

The combination formula is expressed as

$\begin{gathered} C^n_r=\frac{n!}{(n-r)!r!} \\ \\ \end{gathered}$

where

$\begin{gathered} n\Rightarrow total\text{ number of objects} \\ r\Rightarrow number\text{ of object selected} \end{gathered}$

Given that 6 objects are taken at a time from 8, this implies that

$\begin{gathered} n=8 \\ r=6 \end{gathered}$

Thus,

Number of permuations:

$\begin{gathered} P^8_6=\frac{8!}{(8-6)!} \\ =\frac{8!}{2!}=\frac{8\times7\times6\times5\times4\times3\times2!}{2!} \\ 2!\text{ cancel out, thus we have} \\ \begin{equation*} 8\times7\times6\times5\times4\times3 \end{equation*} \\ \Rightarrow P_6^8=20160 \end{gathered}$

Number of combinations:

$\begin{gathered} C^8_6=\frac{8!}{(8-6)!6!} \\ =\frac{8!}{2!\times6!}=\frac{8\times7\times6!}{6!\times2\times1} \\ 6!\text{ cancel out, thus we have} \\ \frac{8\times7}{2} \\ \Rightarrow C_6^8=28 \end{gathered}$

Hence, there are 28 combinations and 20160 permutations.
