The diameter of the circle is 30 feet
To compute the diameter of the circle, we can use the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, the hypotenuse is the diameter of the circle, and the other two sides are the radius and the distance between the chord and the center of the circle.
So, we can write the equation:
diameter^2 = radius^2 + (distance between chord and center)^2
We know the radius is half the diameter, so we can substitute that in:
diameter^2 = (diameter/2)^2 + (15)^2
And we can solve for the diameter:
diameter^2 = diameter^2/4 + 225
diameter^2 = diameter^2/4 + 225
4diameter^2 = diameter^2 + 900
3diameter^2 = 900
diameter^2 = 900/3
diameter = sqrt(900/3)
So the diameter of the circle is 30 feet.

A. /1 and /2 are vertical angles and supplementary.
B. /2 and /3 are complementary angles and congruent.
C. /1 and /3 are vertical angles and congruent.
D. /2 and /4 are supplementary angles and congruent.
Therefore , the solution of the given question of triangle comes out to be the only true option is A.
Triangle definitionAny three points in a plane can be connected to create triangles, which have three sides and three angles. They were one of the very first geometric shapes to be studied. They are particularly important because any polygon, whether it has four, five, six, or n sides, may be split into a triangle.
Here,
Because angles 1 and 2 are close to one another, they are neighboring angles.
A They share a side and are near to each other, making them neighboring angles.
B. The angles are complimentary (add to 90 degrees) False—Angle 2 has a 90 degree angle.
C. They are additional angles. (add to 180) They do not create a straight line, which is untrue.
D. Vertical angles describe them. (Contrary angles) False, they are not created through the intersection of lines.
Therefore , the solution of the given question of triangle comes out to be the only true option is A.

IF m /3 = (9x + 14) and m/5 = (14x - 1), find m/28.
Answer:
∠8 = 139°
Step-by-step explanation:
Before we start solving, let's identify the figure to understand the problem.
We are given two parallel lines that are cut by a transversal.
Two lines are parallel if they have the same arrow head marking.
If two parallel lines are cut by a transversal, the following angles are created:
alternate interior anglesalternate exterior anglesvertical anglesadjacent anglescorresponding anglesI have attached an image of the different types of angles to this response.
Thus, we can use the types of angles to solve for ∠8.
∠3 and ∠5 are corresponding angles. Therefore, they have the same measure.
Set up the equation to solve for x:
∠3 = ∠5
9x + 14 = 14x - 1 . . . . . . substitute the values
14 = 5x - 1 . . . . . . . . subtract 9x from the LHS and RHS
15 = 5x . . . . . . . . . . add 1 to the LHS and RHS
∴ 3 = x . . . . . . . . . . . . divide the LHS and RHS by 5 to isolate x
Now that we know what x is, we can substitute it into the value of ∠3.
∠3 = 9x + 14
∠3 = 9(3) + 14 . . . . substitute the values
∠3 = 27 + 14 . . . . . compute
∴ ∠3 = 41
∠3 and ∠8 are adjacent angles. Therefore, they add up to 180°.
Set up the equation to solve for ∠8:
∠8 + ∠3 = 180
∠8 + 41 = 180 . . . . substitute the known values
∴ ∠8 = 139° . . . . . subtract 41 from the LHS and RHS to isolate ∠8

a paint roller has a width of 12 inches and a radius of 3 inches, what is the surface area that can be painted with one complete rotation of the roller
The surface area that can be painted with one complete rotation of the roller is 226.19 inches².
Surface area is defined as the total amount of area that covers the surface or outside of a three-dimensional figure.
A paint roller is in the shape of a cylinder. To determine the surface area that can be painted with one complete rotation of the roller, solve for the surface area of a cylinder without the circular bases.
SA = 2πrh
where SA = surface area
r = radius of the base = 3 inches
h = height of the cylinder = width = 12 inches
Plug in the values and solve for the surface area.
SA = 2πrh
SA = 2π(3 inches)(12 inches)
SA = 226.19 inches²
Hence, the surface area that can be painted with one complete rotation of the roller is 226.19 inches².

O Yes; the sum of any two lengths is greater than the third length.
O No; the sum of any two lengths is not greater than the third length.
O Yes; the sum of any two lengths is equal to the third length.
O No; the sum of any two lengths is greater than the third length
Answer:
No; The sum of any two lengths is NOT greater than the third length
Step-by-step explanation:
It is given that three objects, a desk, a filing cabinet, and a printer, form a triangle.
Use the Triangle Inequality Theorem to determine whether the given distances can be the lengths of the sides of a triangle.
9+7=16>2
9+2=11>7
7+2=9=9
The sum of one pair of lengths is equal to the third length. Therefore, the distances between the desk, the printer, and the desk and the filing cabinet cannot be 7ft and 2ft since 7+2 equals 9.

Logical partition - A partition within an extended partition

Primary partition - The section of the hard drive that will become the bootable drive
IBM and Microsoft initially kept internal lists of designated partition types to be used in the MBR partition table. As the market for PC operating systems and disc tools expanded and became more open, other suppliers also needed to give their products specialised partition kinds. Third parties began to merely allocate partition types on their own behalf in a largely uncoordinated trial-and-error fashion because Microsoft neither documented all of the partition types already given by them nor wished to retain foreign assignments. This resulted in several conflicting assignments, which occasionally caused serious compatibility issues between certain products. [1]
In the 1990s, a number of industry professionals including Hale Landis, Ralf D. Brown, Matthias R. Paul, and Andries E. Brouwer began investigating partition kinds.

what is the vertex and y-intercept of y=-(x+3)^2+4
vertex: (−3, −4); y-intercept: 13
vertex: (3, −4); y-intercept: −9
vertex: (3, 4); y-intercept: −5
vertex: (−3, 4); y-intercept: −5
Answer:
Vertex → (x, y) = (− 3, − 4)
x intercepts → (x, y) = (−5, 0) and (−1, 0)
y intercept → (x, y) = (0, 5)
Step-by-step explanation:
Set y = 0 = ( x + 3)^2 − 4
Add 4 to both sides
4 = (x + 3)^2
Square root both sides
± 2 = x + 3
Subtract 3 from both sides
x = − 3 ± 2
x intercepts → (x, y) = (− 5, 0)
and
(− 1, 0)
You may if you so choose determine the vertex from this point
x vertex is midway between the x intercepts then by substitution determine y. The method I used later takes less work.
Given

x vertex = (-1) ×(+ 3) = − 3
y vertex = − 4
Vertex → (x, y) = (− 3, − 4)
