The circunference C is given by
\(C=2\pi\cdot r\)where Pi is given by
\(\pi=3.1416\)and r (radius) is equal to 1 units (in our case).
By substituting these values into the circunference formula, we get
\(C=2(3.1416)(1)\)which gives
\(C=6.2832\)that is, the circunferece is equal to 6.2832 units.

HELP! IT'S OVERDUE! An engineer is building a bridge that should be able to hold a maximum weight of 1 ton. He builds a model of the bridge that is exactly 4 times smaller than the actual bridge. 16 ounces = 1 pound. 2,000 pounds = 1 ton. If a test of the model shows that it holds 8,000 ounces, will the bridge hold 1 ton? 1. 8,000 ounces on the model is equal to (A.32,000 B.35,000 C.80,000) pounds on the actual bridge. 2.

Solve for x (see image)
Answers
Answer:
x = 18
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
x^2 + 24^2 = ( 12+x)^2
FOIL the right side
x^2 +576 = 144 + 24x + x^2
Subtract x^2 from each side
576 = 144 + 24x
Subtract 144 from each side
576-144 = 24x
432 = 24x
Divide each side by 24
432/24 = 24x/24

What are index forms?Index forms are described as mathematical forms that are used to represent numbers or values that are too large or small in more convenient ways.
From the information given, we have that;
(7q³ˣ)³ = 343q³⁶
expand the bracket for the values
7³. q⁹ˣ = 343q³⁶
Now find the common exponents, we have;
7³. q⁹ˣ= 7³. q³⁶
Divide the values, we have;
q⁹ˣ = q³⁶
Equate the exponents, we get;
9x = 36
Divide both sides by the coefficient of x, we get
9x/9 = 36/9

A room is 12 m long and the width is 1.5 m more than the height. If the area of the four walls is 105 m², find the height of the room giving your answer correct to 2 decimal places.
Answers
Answer:
Step-by-step explanation:
Let's start by finding the width of the room in terms of its height.
Let the height of the room be h meters. Then the width of the room is (h + 1.5) meters.
The area of the four walls is equal to the perimeter of the room multiplied by the height of the room. The perimeter of the room is:
2(length + width) = 2(12 + h + 1.5) = 2(h + 13.5)
So, the area of the four walls is:
2(h + 13.5)h + 2(h + 13.5)(h + 1.5) = 105
Simplifying and solving for h, we get:
2h^2 + 27h - 60 = 0
Using the quadratic formula, we get:
h = (-b ± sqrt(b^2 - 4ac))/(2a)
where a = 2, b = 27, and c = -60.
Plugging in the values, we get:
h = (-27 ± sqrt(27^2 - 4(2)(-60)))/(2(2))
h = (-27 ± sqrt(1101))/4
h ≈ 2.34 or h ≈ -12.84
We can ignore the negative solution since the height of the room must be positive. Therefore, the height of the room is approximately 2.34 meters, rounded to two decimal places.
Provide the missing reasons for the proof.

1. Initial prediction for the data set with smaller Mean Absolute Deviation was Period A. Prediction was wrong.
2. The Mean Absolute Deviation for Period A is 1.8 and Period B, 1.1
This means that period B has a smaller Mean absolute deviation.
How do we calculate the Mean Absolute Deviation?We start by finding the mean for each set;
Period A: Mean = (1×92 + 1×94 + 3×95 + 1×96 + 2×97 + 1×99 + 1×100)/10
= 960/10
= 96
Period B: Mean = (1×94 + 3×95 + 1×96 + 4×97 + 1×98)/10
= 961/10
= 96.1
Period A:
Mean Absolute Deviation = ((92-96) + (94-96) + 3(95-96) + (96-96) + 2(97-96) + (99-96) + (100-96))/10
Mean Absolute Deviation = (4 + 2 + 3 + 0 + 2 + 3 + 4)/10
Mean Absolute Deviation = 1.8
Period B:
Mean Absolute Deviation = ((94-96.1) + 3(95-96.1) + (96-96.1) + 4(97-96.1) + (98-96.1))/10
Mean Absolute Deviation = (2.1 + 3.3 + 0.1 + 3.6 + 1.9)/10
Mean Absolute Deviation = 1.1

What the meaning of "f is order-preserving if x < y implies f(x) < f(y)"?
Answers
An order-preserving function is one where x < y implies f(x) < f(y). An isomorphism is a one-to-one order-preserving function between two partially ordered sets, while an automorphism is an isomorphism of a set to itself.
In the given excerpt, it explains the concepts of order-preserving functions, isomorphisms, and automorphisms in the context of partially ordered sets.
Order-Preserving Function:
A function f: P -> Q, where P and Q are partially ordered sets, is said to be order-preserving if for any elements x and y in P, if x < y, then f(x) < f(y). In other words, the function preserves the order relation between elements in P when mapped to elements in Q.
Increasing Function:
If P and Q are linearly ordered sets, then an order-preserving function is also referred to as an increasing function. It means that for any elements x and y in P, if x < y, then f(x) < f(y).
Isomorphism:
A one-to-one function f: P -> Q is called an isomorphism of P and Q if it satisfies two conditions:
a. f is order-preserving: For any elements x and y in P, if x < y, then f(x) < f(y).
b. f is onto (surjective): Every element in Q has a pre-image in P.
When an isomorphism exists between (P, <) and (Q, <), it means that the two partially ordered sets have a structure that is preserved under the isomorphism. In other words, they have the same ordering relationships.
Automorphism:
An automorphism of a partially ordered set (P, <) is an isomorphism from P to itself. It means that the function f: P -> P is both order-preserving and bijective (one-to-one and onto). Essentially, an automorphism preserves the structure and order relationships within the same partially ordered set.
These concepts are fundamental in understanding the relationships and mappings between partially ordered sets, particularly in terms of preserving order, finding correspondences, and exploring the symmetry within a set.

Is this or is this not a function?
Answers
Answer:
This is not a function
Step-by-step explanation:
Assuming that the line in question is parallel with the y axis, by using the line test we can see that the line is not a function. The line test is where you draw straight lines going vertically over the graph and if the lines touch the figure in question more than once that means it's not a function.
This can also be proved by imagining there are 2 different points on the line in question. Since the line is straight vertically that means that the points will share the same x value for different y values, which makes it not a function
Answer:
This is not a function.
Step-by-step explanation:
The questioned parallel line within the y-axis does not meet the requirements to be a function. The line test, as the other person stated, is a test where lines are drawn over the points to determine if the graph / model is, or is not a function. Doing so in this process, if the lines touch the same point more than once, that means the graph is not a function.
