Answer:
The equation of the circle is [tex]x^2 + (y + 3)^2 = 11[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
Center (0, -3)
This means that [tex]x_0 = 0, y_0 = -3[/tex]
Radius square root of 11
This means that [tex]r = \sqrt{11}[/tex]
Equation of the circle:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - 0)^2 + (y - (-3))^2 = (\sqrt{11})^2[/tex]
[tex]x^2 + (y + 3)^2 = 11[/tex]
The equation of the circle is [tex]x^2 + (y + 3)^2 = 11[/tex]

Answer:
KRM = 44 degrees, MRD = 46 degrees
Step-by-step explanation:
This angle is a right angle so it equals 90 degrees. That means that equations 3g + 29 and 7g + 11 will amount to 90 degrees.
(3g + 29) + (7g + 11) = 90
Combine like terms:
10g + 40 = 90
10g = 50
g = 5
Plug in 5 to both equals (in this case the question only asks for 3g + 29 or KRM):
3(5) + 29 =
15 + 29 =

The radius of the sphere is approximately 4.2 feet.
What is the volume of the sphere?To find the volume of a specific sphere, we need to know its radius. Once we have the radius, we can plug it into the formula and calculate the volume.
The formula for the volume of a sphere is:
V = (4/3) x π x r^3
where V is the volume of the sphere, r is its radius, and π is a mathematical constant approximately equal to 3.14.
We are given the volume of the sphere, so we can plug it into the formula and solve for the radius:
384 = (4/3) x π x r^3
Dividing both sides by (4/3) x π, we get:
r³ = 384 / ((4/3) x π)
r³ = 72.825
Taking the cube root of both sides, we get:
r ≈ 4.243
The radius of the sphere is approximately 4.2 feet.

what is a secant of a circle
In geometry, a secant of a curve is a line that intersects the curve at a minimum of two distinct points. In the case of a circle, a secant will intersect the circle at exactly two points.
Which step is the same in the construction of a perpendicular line through a point on a line and the construction of a perpendicular line through a point off a line?
Create only one arc on the original line.
Create two arcs on the original line.
Place the compass on only one point off the original line.
Place the compass on only one point on the original line.
Step-by-step explanation:
Create two arcs on the original line.
Place the compass on two points on the original line, one after another for marking a point.
make a line from the original point on the line to the marked point (MP)
the sketch as attached
For making a perpendicular line through a point open the compass to a radius that is less than half of the segment and draw an arc intersecting line and then draw arcs using the intersection points. In the last construct a line that joins the two points.
The steps that involve the same drawing of a perpendicular line by a Point on s line and perpendicular to the point off a line is to put the compass on a point off the original line.Hence the option C is correct.

Point m is located at 4,-2 what is located 2 units for point m
Answer:
None
Step-by-step explanation:
Given
[tex]m = (4,-2)[/tex]
Required
Point 2 units from m
There are 4 possible points 2 units from m and they are:
[tex]m' = (4+2,-2) = (6,-2)[/tex]
[tex]m" = (4,-2+2) = (4,0)[/tex]
[tex]m'''= (4-2,-2) = (2,-2)[/tex]
[tex]m'''' = (4,-2-2) = (4,-4)[/tex]
From the graph, we have:
[tex]A = (4,2)[/tex]
[tex]B = (-4,2)[/tex]
[tex]C = (2,-3)[/tex]
None of the points is 2 units from m
Point m is located at (4,-2), then point C is located approximately 2 units from point m.
A point in a graph is its location denoted using x and y axis.
Given the following information:
Coordinates of point m=(4,-2)
Coordinates of point A=(4,2)
Coordinates of point B=(-4,2)
Coordinates of point C=(2,-3)
Formula used to find distance between two points say (x1,y1) and (x2,y2) is
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
D1 distance between m and A is
[tex]D_1=\sqrt{(4-4)^2+(2+2)^2}\\D_1=4[/tex]
D2 distance between m and B is
[tex]D_2=\sqrt{(-4-4)^2+(2+2)^2}\\D_2=4\sqrt5[/tex]
D3 distance between m and C is
[tex]D_3=\sqrt{(2-4)^2+(-3+2)^2}\\D_3=\sqrt5\\D_3=2.2\\[/tex]
D3 is approximately equivalent to 2 not exactly 2.
Thus, point C is approximately at 2 units from m.

Please help! What is the area in square units?
9514 1404 393
Answer:
103 square units
Step-by-step explanation:
There is a way to find the area by counting grid points, but the fairly large number of them suggests that could be both tedious and prone to error. Instead, we'll chop up the figure into a trapezoid and two triangles.
From the top corner of the right edge draw a horizontal line across the figure. This will make the bottom portion a trapezoid and the top portion two triangles. The length of that horizontal line is 13 units, the height of the trapezoid, and the sum of the triangle bases.
The bottom trapezoid has a left-side base of 7 units and a right-side base of 6 units. Its area is ...
A = 1/2(b1 +b2)h
A = 1/2(7 +6)(13) = 1/2(13)(13) = 169/2 = 84.5 . . . square units.
The right top triangle has a base of 11 and a height of 3, so its area is ...
A = 1/2bh
A = 1/2(11)(3) = 33/2 = 16.5 . . . square units
The left top triangle has a base and height of 2 units each, so its area is ...
A = 1/2(2)(2) = 2 . . . square units
Then the total area of the figure is ...
84.5 +16.5 +2 = 103 . . . square units
_____

Here is the check by counting grid points. The number of grid points on the outline of the figure is i=22. The number of grid points inside the figure appears to be b=93. Then the area by Pick's theorem is ...

Choose the polynomial written in standard form.
xy2 + 4x4y + 10x2
x4y2 + 4x3y + 10x
x4y2 + 4x3y5 + 10x2
x6y2 + 4x3y8 + 10x
Answer:
Standard form means that you write the terms by descending degree.
x^4y^2 + 4x^3y + 10x^2
The degree of the first term x^4y^2 is 4+2=6
The degree of the second term 4x^3y is 3+1=4
The degree of the third term 10x^2 is 2
The terms are written by descending degree. Therefore, polynomial x^4y^2 + 4x^3y + 10x^2 is written in standard form.

A formula for finding the perimeter of a rectangle is P=2L+2W. If you know the perimeter (P) and width (W) of a rectangle, which formula can you use to find the length (L)?
Step-by-step explanation:
→ P = 2L + 2W
→ P = 2(L + W)
→ P ÷ 2 = L + W
