Answer: 8.49cm

Step-by-step explanation:

Given Data:

Let a be no of side = 6

Therefore

d = √2 * a

d = √2 * 6

d = 1.4142 * 6

d = 8.49cm

The diagonal is 8.49cm

Answer:

The length of the diagonal of a square of length 6 cm is 6√2 cm = 8.485 cm

Step-by-step explanation:

English Translation

Determine the length of the diagonal of a square with a side of 6 cm.

Solution

Let the length of the diagonal be d.

And the length of each side of the square be s.

Note that s = 6 cm

The two sides of the square and the diagonal form a right angled triangle with the diagonal serving as the hypotenuse.

Using Pythagoras theorem, the square of the hypotenuse is equal to the sum of the individual squares of the two other sides of the right angled triangle.

d² = s² + s²

d² = 2s²

d = √(2s²)

d = s √2

note that s = 6 cm

d = 6 × √2 = 6√2 cm = 8.485 cm

Hope this Helps!!!

Let r3 have the euclidean inner product. let u = (-1, 1, 1) and v = (-7, 6, 15). if ||ku + v||= 7, what is k? give the exact ans
amm1812
Mak\mathbf u+\mathbf v=k(-1,1,1)+(-7,6,15)=(-k-7,k+6,k+15)

Recall that for a vector \mathbf x\in\mathbb R^n, we have \|\mathbf x\|=\sqrt{\mathbf x\cdot\mathbf x}. So we have

\|k\mathbf u+\mathbf v\|=\sqrt{(k\mathbf u+\mathbf v)(k\mathbf u+\mathbf v)}=7
\implies k^2\mathbf u\cdot\mathbf u+2k\mathbf u\cdot\mathbf v+\mathbf v\cdot\mathbf v=49
\implies3k^2+56k+261=0
\implies k=-9,-\dfrac{29}3

Danielle wants to know if a new dresser will fit next to her bed. The dresser she would like to buy is 73 centimeters wide. She
zhannawk [14.2K]

Answer:

No.

The dresser's width(28.74in) is greater than the remaining free width(10in) in the room.

Step-by-step explanation:

First, convert the chest width into inches,73cm=28.74 \ in

To find the excess width after fitting the bed in her room, we subtract the bed width from the room's width:

Width_R=86 \ in\\Width_B=76 \ in\\\\Width_{excess}=Width_R-Width_B\\\\=86\ in -76\ in\\\\=10\ in

Since 10in is less than 28.74in, the dresser will not fit next to her bed.
