what is the area of this quadrilateral

Answer: [tex](-2,3)[/tex], [tex]r=5\ \text{units}[/tex]

Step-by-step explanation:

Given

the equation is [tex]x^2+y^2+4x-6y-12=0[/tex]

completing the square

[tex]\Rightarrow (x^2+2\times 2\times x+4-4)+(y^2-2\times3\times y+9-9)-12=0\\\Rightarrow (x^2+2\times 2\times x+4)+(y^2-2\times3\times y+9)-12-4-9=0\\\Rightarrow (x+2)^2+(y-3)^2=25\\\Rightarrow (x+2)^2+(y-3)^2=5^2\\\Rightarrow (x-(-2))^2+(y-3)^2=5^2[/tex]

Thus, the center of the circle is [tex](-2,3)[/tex] and radius is [tex]r=5\ \text{units}[/tex]

Answer: b

Step-by-step explanation:

Answer:

1.The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

2.The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. ... If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above.

3.There are no outliers. Explanation: An observation is an outlier if it falls more than above the upper quartile or more than below the lower quartile.

4.20. The "average" you're talking about is actually called the "mean". It's not exactly answering your question, but a different statistic which is not affected by outliers is the median, that is, the middle number. {90,89,92,91,5} mean: 73.4 {90,89,92,91,5} median: 90.

Answer:

x = 0.29 m

Step-by-step explanation:

Given :

The length of the hammer is = 0.29 m

The hammer is a tool that may be used in various operation or work by mechanics, plumbers, or masonries and even by normal people.

So let the length of the hammer be x.

The length of the hammer is expressed in meters or inches or centimeters.

Therefore, the expression of length of the hammer is expressed as x = 0.29 m.

Answer: the radius would be B

Answer:

64

8² = 64

4³ = 64

Answer:

17

Step-by-step explanation:

We can use this formula:

[tex]\sqrt{(x2-x1)^2 + (y2 -y1)^2}[/tex] where x and y indicate the coordinates of the two points

[tex]\sqrt{4-(-4)^2 + (8-(-7)^2} = \sqrt{64 + 225} = \sqrt{289} = 17[/tex]

Answer:

17

Step-by-step explanation:

You are given two points so you use the distance formula

[tex] \sqrt{( {x 2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]

Substitute your points into the formula

Answer:

s = 24.05

Step-by-step explanation:

Given

v² = u² + 2gs ← substitute v = 25, u = 12, g = 10

25² = 12² + (2 × 10 × s)

625 = 144 + 20s ( subtract 144 from both sides )

481 = 20s ( divide both sides by 20 )

24.05 = s

Step-by-step explanation:

Any positive number can. be a side length. It cannot pass 7 because a square with 49 sqr lnches as a area has side lengths with the measures of 7.

[tex]0 \leqslant x \leqslant 7[/tex]

Answer:

29013

Step-by-step explanation:

Do PEMDAS.  Multiply 69 and 420 and 1 and 44.  Then you will get 28980+77-44.  Then add and subtract from there.  Answer is 29,013.

Answer:

y = 1/2x + 2

Step-by-step explanation:

y = mx + b is the format you use.

m = slope (rise over run)

b = y - intercept

Answer:

25

Step-by-step explanation:

=> 5√3-5√2 × 5√3+5√2

=> 25×3 - 25×2 [(a-b) (a+b) = a²-b²]

=> 75 - 50=> 25

Answer:

Step-by-step explanation:

Convert each number to its decimal equivalent for easier comparison with the other numbers:

1/8 = 0.125        1 (smallest)

2/4 = 0.50         3

8/4  = 2.0           4

3/15  = 0.20        2

2 2/7 = 2.28        6  (largest)

20/10​ = 2.00       5 (next to largest)

The smallest number is 1/8 (see above), and the largest is 2.28 (2 2/7).

It rained 184 days out of 365:

It rained 50.41% of days

Answer:

8. 15

10. 90

12. 36

Step-by-step explanation:

8.

The mean of the 5 data is 51.

(55 + 60 + 35 + 90 + x) ÷5 = 51

(240 + x) ÷5 = 51

240 + x = 255

x = 15

10.

The mean of the 5 data is 127.

(100 + 112 + 98 + 235 + x) ÷5 = 127

(545 + x) ÷5 = 127

545 + x = 635

x = 90

12.

The mean of the 5 data is 40.

(34 + 56 + 45 + 29 + x) ÷5 = 40

(164 + x) ÷5 = 40

164 + x = 200

x = 36

Volume is always cubed.(³)

Area is always squared (²)

Plug it in.

Answer:

In mathematics, a set is closed under an operation if performing that operation on members of the set always produces a member of that set. For example, the positive integers are closed under addition, but not under subtraction: 1 − 2 is not a positive integer even though both 1 and 2 are positive integers.

$0.65 per pound

Step-by-step explanation:

9.75 divided by 15 = 0.65

Answer:

1. 31.3%

2. 34.35%

3.62.6%

Step-by-step explanation:

There were 131 acoustic guitars, and 41 of them needed neck repair.

41/131 = 0.3130 = 31.3%

There were 262 total guitars serviced by Emely. 60 of them were acoustic and needed a string repaired, and 30 of them ere acoustic and needed repair, so 90 of them were acoustic and did not need neck repair.

90/262 = 0.3435 = 34.35%

There were 131 electric guitars. 48 of them had a broken string and 34 of them needed body repairs. So 82 of them needed either string or body repairs.

82/131 = 0.6260 = 62.6%

Answer:

144

Step-by-step explanation:

It rotates out of 360 degrees, and since it is a pentagon that rotates from two of its vertices, then 360/5 would give us the amount it is rotating from one vertice. So 72. Then multiply it by two because you are moving from e to b.
