What is the value of the element at h21? H= [6, 52, -4]
[15, 9, 75]
[-1, 23, 2]

Answers

Answer 1
Answer:

Answer:

Thus, value of h_(21)=15

Step-by-step explanation:

H=\left[\begin{array}{ccc}6&52&-4\n15&9&75\n-1&23&2\end{array}\right]

Here,h_(pq) represents position of element of matrix h represented by p row and q column.

So, h_(21) represents position of element of matrix h represented by 2 row and 1 column.

Thus, value of h_(21)=15
Answer 2
Answer: hrc
r=row
c=collumn

so go the 2nd row
(15,9,75)
and go to the 1st collumn
15


the value is 15

Steve is turning half of his backyard into a chicken pen. His backyard is a 24-meter by 45-meter rectangle. He wants to put a chicken wire fence along the west side of the yard, the south side of the yard, and along the diagonal connecting the northwest to the southeast corner of the yard. How many meters of fencing will Steve need to fully enclose this area?

Answers

The diagonal line is equal to \sqrt{24^(2) + 45^(2) } using pythagoras' theorem of a^(2) + b^(2) = c^(2). This gives us a value of 51m for the diagonal line.

TOTAL; 51+24+45=120m of fencing 

Answer:

51 meters

Step-by-step explanation:

We can use the Pythagorean Theorem to find the length of the diagonal line.

The equation for the Pythagorean Theorem is

a^2 + b^2 = c^2a  

2

+b  

2

=c  

2

a, squared, plus, b, squared, equals, c, squared

where aaa and bbb are the lengths of the two legs of the triangle, and ccc is the length of the hypotenuse.

In this case a=24,b=45,a=24,b=45,a, equals, 24, comma, b, equals, 45, comma and c=xc=xc, equals, x.

Hint #33 / 4

\begin{aligned} 24^2+45^2 & = x^2\\ 576+2025 & = x^2\\ 2601 & = x^2\\ \sqrt{2601} & = x\\ 51 & = x \end{aligned}

What is the most precise term for quadrilateral ABCD with vertices A(4, 4), B(5, 8), C(8, 8),and D(8, 5)?
square
rhombus
kite
Parallelogram

Answers

The most precise term for quadrilateral ABCD with vertices A(4, 4), B(5, 8), C(8, 8) is a kite.

Option C is the correct answer.

What is a kite?

A kite is a quadrilateral where the adjacentsides are equal which means there are two pairs of equal sides.

We have,

Quadrilateral ABCD:

A = (4, 4)

B = (5, 8)

C = (8, 8)

D = (8, 5)

Now,

A__________B

|                      |

|                      |
|                      |

D_________ C

We see the distance between the two points.

AB = √(8 - 4)² + (5 - 4)² = √(4² + 1) = √17

AD = √(5 - 4)² + (8 - 4)² = √(1² + 4²) = √17

AB = AD

BC = √(8 - 8)² + (8 - 5)² = √9 = 3

CD = √(5 - 8)² + (8 - 8)² = √9 = 3

BC = CD

AB and AC are adjacent sides.

CD and DB are adjacent sides.

So,

The quadrilateral ABCD is a kite.

Thus,

The quadrilateral ABCD is a kite.

Area of room is 320 and width is 4/5 of length

Answers

Area is w*l and w=\frac{4l}5, thus the area is \frac{4l^2}5. Make it equal to 320 and you get l^2=400, thus l=\pm{20}, the minus one not being meaningful in our context. Thus the length is 20, while the width is 16.
