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]

Find the area and the circumference of the circle. Round your answers to the nearest hundredth.
The Area Of The Circle Is 452.16
The Circumference Of The Circle Is 75.36
its a function or not fuction?
answer:
it's a function
step-by-step explanation:
according to g00gle- in mathematics, a function is a binary relation between two sets that associates to each element of the first set exactly one element of the second set. typical examples are functions from integers to integers, or from real numbers to real numbers.
but the simple definition is that a function is when the x value isn't being repeated. and since in your case it isn't, the table is a function
another way to solve-
for this, we will put the pairs into a graph then perform the line test-
as you can see each point has its own individual line, therefore, meaning it passed the vertical line test
good luck :)

A home business has an average income of $900.00 per month with a standard deviation of $15.00. If the income in a given month is $930.00, what z-score corresponds to this value?
Enter the answer to the nearest tenth. Z= ?
Answer:
2.00
Step-by-step explanation:
Z score is a statistical that corresponds to the standardization of the regular score to a normal distribution
The formula for Z score is Z = [X - mean ]./ (standard deviation)
Here X = 930.00; mean = 900.00; and standard deviation = 15.00
Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00

Answer:
100 cubic in
Explanation
step 1: divide the figure into two
step 2 : find area then multiply by height of the cuboid
step 3 : add both
Answer:
The answer is 100.
Step-by-step explanation:
Volume = weight times height times length = 5 times 1 times 8 = 40
Volume = weight times height times length = 5 times 2 times 6 = 60
So now that we have the volume of each rectangular prism, we must add them together to get the full volume.
60 + 40 = 100

Carl has $25.00 to spend o six packs of soda for the dance. If the cost of one-six pack is $2.50, which inequality could be used to represent this relationship?
Answer:
25 ≤ 2.5n
Step-by-step explanation:
Total budgeted amount = $25
Cost per pack of = $2.50
To represent the relationship using inequality :
Let the Total number of packs purchased = n
Hence,
Total budgeted amount ≤ (cost per pack * number of packs)
25 ≤ 2.5n
This means the total actual purchase made should be less than or equal to the budgeted amount.
Which goes to this inequality x + 1 < 3
A coat at a store is originally priced at $54.99. The store marks the price down to $32.99. To the nearest percent, what is the percent markdown of the coat?
Answer:
66.6%
Step-by-step explanation:
Step one
given
A coat at a store is originally priced at $54.99
The store marks down the price down to $32.99
Required
the percent decrease
Step two:
the percent decrease= change in price/ old price*100
the percent decrease= 54.99-32.99/54.99*100
the percent decrease= 22/ 32.99*100
the percent decrease= 0.666*100
the percent decrease= 66.6%

what is 3053.62805928 to the nearest cubic inch
Answer:
3054
Step-by-step explanation:
When you round to the nearest unit, in this case inch, you need to look at the tenths place.
5 or more raise the score
4 or less, let it rest.
------------------------------------------
Since the number in the tenths place is a 6, it will bump up the number to a 3054.
Good Luck!

The circumference of each of the smaller circles is 12 mm. Find the area of the shaded region.
Answer:
11.45mm^2
Step-by-step explanation:
Given data
Circumference= 12mm
The expression for the circumference is
C= 2πr
12= 2*3.14*r
12= 6.28r
r= 12/6.28
r= 1.91mm
Hence the area of each small circle is
A= πr^2
A= 3.14*1.91^2
A= 3.14*3.6481
A=11.45mm^2

Does Brainly help with Geometry?
Answer:
Yes!
Step-by-step explanation:
Brainly can function as an algebra practice tool, a geometry solver, and a fraction calculator.
What is Geometry?One of the first areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects. A geometer is a mathematician who specialises in geometry.
The three most popular types of geometry are solid geometry (which deals with items like the line, sphere, and polyhedron) and spherical geometry (which deals with objects like the spherical triangle as well as spherical polygon). Plane geometry deals with objects such as the point, line, oval, triangle, and polygon.
Thus, Brainly can function as an algebra practice tool, a geometry solver, and a fraction calculator.
