Lulu has exactly enough fencing to go around her rectangular garden. She has 40 m of fencing and the garden is 8 m wide. What is

vesna_86 [32]

Answer:12 m

Step-by-step explanation:

Given

Width of garden $W=8\ m$

Total fencing $T=40\ m$

If Lulu has enough fencing to go around her rectangular garden then , it should be equal to perimeter of garden

Suppose L is the length of garden

Therefore perimeter is $P=2(L+W)$

$2(L+W)=40$

$L+W=20$

$L=20-8=12\ m$

thus length of fencing is $12\ m$

Please help me with this.

Swapping rows alters the sign of the determinant:

$\begin{vmatrix} x & y & z \\ -8 & 2 & -12 \\ u & v & w \end{vmatrix} = - \begin{vmatrix} x & y & z \\ u & v & w \\ -8 & 2 & -12 \end{vmatrix}$

Multiplying a single row by a scalar scales the determinant by the same amount:

$\begin{vmatrix} x & y & z \\ u & v & w \\ -8 & 2 & -12 \end{vmatrix} = -2 \begin{vmatrix} x & y & z \\ u & v & w \\ 4 & -1 & 6 \end{vmatrix}$

Then

$\begin{vmatrix} x & y & z \\ -8 & 2 & -12 \\ u & v & w \end{vmatrix} = -(-2) \begin{vmatrix} x & y & z \\ u & v & w \\ 4 & -1 & 6 \end{vmatrix} = 2\times(-6) = \boxed{-12}$

At 2063 ft, the KVLY-TV tower in North Dakota is the world’s tallest supported tower. How long would it take an object to fall f

IgorLugansk [536]

Use the equation of motion under gravity:-

s = 16t^2 where s is the distance and t = time

2063 = 16t^2

t^2 = 2063 / 16 = 128.94 s

t = sqrt 128.94 = 11. 4 seconds to the nearest tenth of a second
