What is the perimeter of rhombus wxyz?

Mathematics
2 answers:
Lunna [17]3 years ago

For this case, the first thing we must do is define the formula of distance between points.

We have then:

d = \sqrt{(x2-x1)^2 + (y2-y1)^2}

From here, we look for the distance between two points of rhombus.

YZ = \sqrt{(5-3)^2 + (5-2)^2} \\YZ = \sqrt{2^2 + 3^2} \\YZ = \sqrt{4 + 9} \\YZ = \sqrt{13}

Then, since all sides have the same length, then the perimeter is given by:

P = 4YZ

Substituting we have:

P = 4\sqrt{13}

Answer:

The perimeter of the rhombus is:

P = 4\sqrt{13}

option 3

One of the properties of rhombus is its sides are congruent. Therefore, we will only need to find the length of one side using the distance formula. At line YZ, the distance is \sqrt{ (x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2}}

D = \sqrt{ (5 -3 )^{2} +(5 -2) ^{2}  }  = √13

To get the perimeter, multiply one side to 4. Hence, the perimeter is 4√13 (C)

Answer: 49

Step-by-step explanation:

The missing constant term in the perfect square is 49.

x^2 + 14x + 49

We need a squart root of something to make the factor add up equal to 14x. If it's a perfect square, we could divide 14 by 2, 14/2 = 7, and we multiply 7^2, we get 49, which is a perfect square.

58 is the difference of Janelle's height and 24.
abruzzese [7]

Answer:

Janelle's height is 82 units.

Step-by-step explanation:

Let j represent Janelle's height.

It is mentioned that, 58 is the difference between Janelle's height and 24.

Mathematically, we can write it as :

j-24 = 58

We can solve it as follows :

Adding 24 both sides,

j-24+24 = 58+24

j = 82

Hence, Janelle's height is 82 units.

an internet passcode consists of a digit followed by a letter, followed by another digit. Assuming the digits are 0-9, how many
anyanavicka [17]
There are 10 single-digits (0 through 9) and 26 letters (A through Z)

For the first slot there are 10 choices which represents selecting a single digit
For the second slot there are 26 choices because we choose a single letter here.
Finally there are another 10 choices for the third slot (assuming repeats are allowed)

Multiply the values out: 10*26*10 = 260*10 = 2600

Answer: 2600
