The area of the octagon is 40 + 40√(2) in simplest radical form.
What is the area of the octagon?
The area of a regular octagon can be calculated using the formula:
Area = (2 + 4 * √2) * s^2
where s is the length of one of the sides.
An equiangular octagon is an octagon in which all of the angles are congruent. In addition, all the side lengths are also congruent. However, in the case of the side lengths of the octagon are given as 1, 2, 3, 4, 1, 2, 3, and 4 in clockwise order.
To find the area of the octagon, we can use the following formula:
Area = 2(1 + 2 + 3 + 4)(4) * (1 + √(2))/4
Area = 2(10)(4) * (1 + √(2))/4
Area = 80 * (1 + √(2))/2
Area = 40 + 40*√(2)
Hence, the area of the octagon is 40 + 40√(2) in simplest radical form.

did Mariah paint in terms of π?
Enter the correct answer in the box in terms of π.
answer: _______ cm squared
The number of square centimeters of the cylinder that Mariah painted is given as follows:
36π cm².
How to obtain the volume and the surface area of a cylinder?The volume of a cylinder of radius r and height h is given by the equation presented as follows:
V = πr²h.
Mariah made a cylinder out of clay that had a radius of 6 cm and a volume of 72π cm^3, hence the height of the cylinder is obtained as follows:
36πh = 72π
h = 2.
The surface area of a cylinder is obtained as follows:
S = 2π r h + 2π r
Hence it's value is of:
S = 2π x (2 x 6 + 6)

What is the Probability.
The value of the conditional Probability is P(A|B) is 1/3.
What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The main distinction between a probability and a conditional probability is that a probability is the likelihood of an event, such as A, occurring, whereas a conditional probability assumes that another event, such as B, has already happened in order to define the probability of an event, such as in the conditional probability of A given B.
Conditional probability is the likelihood that any event A will occur in the presence of another event B that is related to A. P(A|B) illustrates it.
By, Conditional Probability :
P (A∩B) =P (A∩B') - P(B)= 4/9 - 1/3 = 1/9
P(A|B) = P (A∩B)/ P(B)
= (1/9)/(1/3) = 1/3

The logarithmic functions, f(x) and g(x), are shown on the graph.
What is the equation that represents g(x)? Explain your reasoning.
The image of the function after the translation is g(x) = log(x + 1) + 4
What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
here, we have,
f(x)=logx
How to determine the equation of g(x)?
From the graph, the given parameters are:
f(x) = log(x)
From the graph, we can see that:
The graph of f(x) is translated left by 1 unit
The graph of f(x) is translated up by 4 units
This transformation is given as
g(x) = f(x + 1) + 4
Mathematically, this transformation can be represented as
(x, y) = (x + 1, y + 4)
When represented as a function, we have
g(x) = f(x + 1) + 4
Substitute the equation f(x) = log(x)
f(x + 1) = log(x + 1) + 4
So, we have the following equation
g(x) = log(x + 1) + 4
Hence, the equation of g(x) is g(x) = log(x + 1) + 4

last digit of 2 to the power of 47
Answer:
2^1 = 2 -> last digit is 2
2^2 = 4 -> last digit is 4
2^3 = 8 -> last digit is 8
2^4 = 16 -> last digit is 6
2^5 = 32 -> last digit is 2
2^6 = 64 -> last digit is 4
2^7 = 128 -> last digit is 8
We can observe that the last digit follows a pattern of 2,4,8,6,2,4,8 and repeat.
Therefore, 2 to the power of 47 will have the same last digit as 2 to the power of (47 modulo 4) + 3
(47 mod 4) + 3 = 51 mod 4 = 3
The last digit of 2 to the power of 3 is 8
Therefore, the last digit of 2 to the power of 47 is 8.

Y = 2(x-2)²+2 is the equation used to model the bird's vertex form journey.
Vertex form: What is it?A vertex is a point on a polygon where two rays or line segments meet, the sides, or the edges of the object come together. Vertex is the plural form of vertices. For instance, the points A, B, C, D, and E in the aforementioned figures are vertices.
Formula for the general vertex form: f(x) = a(x − h) ² + k
where the vertex is (h,k).
This equation can be used to represent a bird's flight path:
y = 2x² - 8x+10
Vertex form equation conversion
Filling in the square:
y = 2(x² - 4x+5)
y=2
(x²-4x+5+ (2)2- (2)2)

Ax + By + Cz + D = 0
(A, B, C) is the normal vector (90° with the plane).
so, we know with the given normal vector (-6, 3, -3) that
A = -6
B = 3
C = -3

Prove divisibility

The prove that the given expression is divisible by 43 is explained below.
Divisibility of numbers.A number is said to be divisible by a given number when it leaves no remainder after the division. Example; show that 7^7 is divisible by 49.
7^7 = 823543
So that;
823543/ 49 = 16807
To prove that the expression is divisible by 43, we have;
7^8 = 5764801
7^7 = 823543
7^6 = 117649
Then,
7^8 - 7^7 + 7^6 = 5764801 - 823543 + 117649
= 4941258 + 117649
= 5058907

A percentage is defined.A percentage is mathematics is a figure or number that is stated as a proportion of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. However, the symbol "%" used to denote it is frequently used. The percentage amount is flat; there are no dimensions. Given that their numerator is 100, percentages are basically fractions.
Here,
According to the clauses 1/10, n/30, the buyer would receive a 1% reduction if the discount was applied within 10 days.
The consumer would be required to pay the whole amount in 30 days if the payment was not completed within this time frame.
Considering this and the fact that Nieman invoiced $2,400 for the returned goods, you must deduct this sum from their original purchase:
=> $12,200-$2,400= $7,800
Then, you must figure out the discount at 1% of $7,800 and deduct it from $7,800:
=> $7,800*1%= $78
=> $7,800-$78= $7,722
This means that, in the event Nieman Company settles the invoice during in the buy the product, the sum of money needed to complete the transaction is $7,722.

let e be the amount in dollars that jacques spends on salad and pizza. if jacques buys s bowls of salad and p slices of pizza, then the total amount of money he spends (e) can be represented by the equation
The total amount of money (e) spent can be represented by the equation E = ($3.00S) + ($5.00P).
The total amount of money spent will be the sum of money sent of salad and pizza.
The total amount of salad = number of bowls of salad × cost of each bowl of salad
Similarly, the total amount of pizza = number of slices of pizza × cost of each slice of pizza
So, the combined equation will be -
Total money spent = number of bowls of salad × cost of each bowl of salad + number of slices of pizza × cost of each slice of pizza
Keep the values in above mentioned equation -
E = (S × 5) + (P × 3)

Answer: 34.3527303398
Step-by-step explanation: hope it is right
Fill in the P(X=x) values in the table below give a legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6.
The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.
For a probability distribution to be legitimate, the probabilities of all the possible values of a random variable need to add up to 1. So, in this case, the sum of all the probabilities must be equal to 1.
For the given values, we can assign the probability of 0.2 to the values 0 and 3, 0.3 to the value 4 and 0.1 to the value 6, so that the sum of all the probabilities is 1.
Therefore, the legitimate probability distribution for the given discrete random variable X is as follows:
| Value (x) | P(X=x) |
|---|---|
| 0 | 0.2 |
| 3 | 0.2 |
| 4 | 0.3 |
| 5 | 0.2 |
| 6 | 0.1 |
The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.
