What is the best approximation of the area of a circle with a diameter of 17 meters?
Use 3.14 to approximate pi.
Answers
the best approximation of the area of the circle with a diameter of 17 meters is approximately 226.99m².
Why it is and what is diameter?
The diameter of the circle is 17 meters, which means the radius is half of the diameter, or 8.5 meters.
The formula for the area of a circle is:
A = πr²2
where A is the area and r is the radius.
Substituting the value of the radius into the formula, we get:
A = 3.14 x 8.5²2
A = 3.14 x 72.25
A ≈ 226.99
Therefore, the best approximation of the area of the circle with a diameter of 17 meters is approximately 226.99 m².
In geometry, the diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circle. It is the longest chord (a line segment connecting any two points on a circle) of the circle, and it divides the circle into two equal halves, also known as hemispheres.

The linear inequality represented by the graph is y ≤ 1/2x + 2
How to determine the inequality?From the graph, we have the following highlights:
The graph crosses the y-axis at c = 2The graph is a less than or equal to graphNext, we calculate the slope (m) using:
\(m = \frac{y_2 -y_1}{x_2 -x_1}\)
Using the points on the graph, we have:
\(m = \frac{4 -2}{4 -0}\)
Evaluate
m = 1/2
The first highlight implies that the y-intercept is 2.
So, the linear inequality is:
y ≤ mx + c
This gives
y ≤ 1/2x + 2
Hence, the linear inequality represented by the graph is y ≤ 1/2x + 2

Answers
Given:
A prism has a base area of \(20\pi \) square units and a volume of \(120\pi\) cubic units.
To find:
The volume of the cylinder if the cylinder has the same base area and height.
Solution:
Volume of a prism is:
\(V=Bh\)
Where, B is the base area and h is the height of the prism.
The volume of cylinder is:
\(V=\pi r^2h\)
\(V=Bh\)
Where, r is the radius, h is the height of the cylinder and \(B=\pi r^2\) is the base area.
Since base area and height of the cylinder are same as the prism, therefore, there volumes are equal.
Hence the volume of the cylinder is \(120\pi\) cubic units.

$78,000
Answers
Winston's economic profit based on the forgone salary of $60,000, and the revenue of $150,000 is $78,000. The correct option is therefore;
$78,000
What is an economic profit?An economic profit is a profit that accounts for both the explicit and implicit costs of a business. The economic profit is obtained from the difference between the total revenue and the costs including the opportunity costs.
The annual salary of Winston as an accountant = $60,000
The amount Winston's financial asset generates = $4,000 per year
The cost of running the business = $8,000
The amount Winston earns as revenue = $150,000
Therefore;
Winston's opportunity cost which is the forgone alternative, is the amount he earns as an accountant = $60,000
The interest of $4,000, earned from the financial asset = The cost of using the financial asset for the business
The cost of running the business = $8,000
The total cost = Opportunity cost + Cost of making use of the financial asset + The business running cost
The total cost = $60,000 + $4,000 + $8,000 = $72,000
The economic profit = The total revenue - The total cost
Therefore;
Winston's economic profit = $150,000 - $72,000 = $78,000Learn more on economic profits here: https://brainly.com/question/13991283

Jeremy has a fish tank that has a 30 cm by 90 cm rectangular base. The water is 25 cm deep. When he drops rocks in
the tank, the water goes up by 2 cm. What is the volume in liters of the rocks?
The volume of the rocks is ____ L
Answers
The volume of water displaced can be calculated by finding the volume of the rectangular prism that is formed by the portion of the rocks that is submerged in the water. The length and width of the prism are the same as the base of the tank (30 cm by 90 cm), and the height is 2 cm (since the water level rises by 2 cm when the rocks are added). Therefore, the volume of water displaced by the rocks is:
V_water = 30 cm x 90 cm x 2 cm = 5400 cm^3
To convert the volume to liters, we divide by 1000:
V_water = 5400 cm^3 ÷ 1000 = 5.4 L
Therefore, the volume of the rocks is 5.4 L.

The expansion will be 64d^6 + 1152d^5 + 9720d^4 + 43740d^3 + 98415d^2 + 145458d + 729
How to expand the valueWe can expand (2d+3)^6 using the binomial theorem, which states that:
(a + b)^n = nC0 * a^n * b^0 + nC1 * a^(n-1) * b^1 + nC2 * a^(n-2) * b^2 + ... + nCn-1 * a^1 * b^(n-1) + nCn * a^0 * b^n
where nCk is the binomial coefficient, given by:
nCk = n! / (k! * (n-k)!)
Expanding (2d+3)^6 using this formula, we get:
(2d+3)^6 = 6C0 * (2d)^6 * 3^0 + 6C1 * (2d)^5 * 3^1 + 6C2 * (2d)^4 * 3^2 + 6C3 * (2d)^3 * 3^3 + 6C4 * (2d)^2 * 3^4 + 6C5 * (2d)^1 * 3^5 + 6C6 * (2d)^0 * 3^6
Simplifying each term using the binomial coefficient formula, we get:
(2d+3)^6 = 1 * 64d^6 * 1 + 6 * 32d^5 * 3 + 15 * 16d^4 * 9 + 20 * 8d^3 * 27 + 15 * 4d^2 * 81 + 6 * 2d * 243 + 1 * 1 * 729
Simplifying each term further, we get:
(2d+3)^6 = 64d^6 + 1152d^5 + 9720d^4 + 43740d^3 + 98415d^2 + 145458d + 729

This graph shows a proportional relationship.
What is the constant of proportionality?
Answers
The constant of proportionality is a crucial aspect of a proportional relationship, as it tells us how much one variable changes in relation to the other. It can be calculated from the equation of the relationship, or from the slope of the graph if it is a linear relationship.
A proportional relationship is a mathematical equation that expresses two variables that are in proportion to one another. In this type of relationship, if one variable is multiplied by a certain constant factor, then the other variable will be multiplied by the same constant factor. For example, if the cost of 3 books is $15, then the cost of 6 books will be $30. In this case, the number of books and the cost of the books are in proportion to one another.
The constant of proportionality is the constant factor by which the two variables are multiplied to obtain each other. In other words, it is the ratio between the two variables that remain constant in a proportional relationship. It can be represented by the letter k, and is calculated by dividing one variable by the other.
To find the constant of proportionality from a graph, we need to look at the slope of the line. The slope is the ratio between the change in the y-values and the change in the x-values, which is also known as the rise over run. If the graph shows a proportional relationship, then the slope will remain constant throughout the graph.
For example, if the graph shows the relationship between the number of hours worked and the amount of money earned, and the slope is 10, then the constant of proportionality is 10. This means that for every hour worked, the person earns $10. The equation for this proportional relationship can be written as y = 10x, where y represents the amount of money earned and x represents the number of hours worked.
In conclusion, the constant of proportionality is a crucial aspect of a proportional relationship, as it tells us how much one variable changes in relation to the other. It can be calculated from the equation of the relationship, or from the slope of the graph if it is a linear relationship.

The distance between two points is √39 One endpoint is (4,−3). It is known that the y-coordinate of the other endpoint is 2.
What is the x-coordinate of this endpoint?
Answers
Answer:
\((4-\sqrt{14}, 2)\text{ or } (4+\sqrt{14}, 2)\)
Step-by-step explanation:
We have the two points: (4, -3) and (x, 2).
We know that the distance between them is √39.
To find our x-coordinate of the second point, we can use the distance formula:
\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2\)
Let (4, -3) be (x₁, y₁) and let (x, 2) be (x₂, y₂). We also know that the distance d is √39. Substitute:
\(\sqrt{39}=\sqrt{(x-4)^2+(2-(-3))^2\)
Solve for x. First, let's square both sides. This cancels out the square roots:
\(39=(x-4)^2+(2+3)^2\)
Evaluate the second term on the right:
\(39=(x-4)^2+(5)^2\)
Square:
\(39=(x-4)^2+25\)
Subtract 25 from both sides:
\(14=(x-4)^2\)
Take the square root of both sides. Since we're taking an even root, we need plus/minus. So:
\(x-4=\pm\sqrt{14}\)
Add 4 to both sides:
\(x=4\pm\sqrt{14}\)
Therefore, there exists two possibilities for our second point. It can either be:
\((4-\sqrt{14}, 2)\text{ or } (4+\sqrt{14}, 2)\)
And we're done!

The height of the building is approximately 78.63 meters.
The following is a step-by-step explanation of how to solve the problem. We'll need to use some trigonometric concepts and formulas to find the solution.
Draw a diagram of the situation described in the problem to get a better understanding of the problem. The diagram would have a right-angled triangle with angle of elevation of 66° at the bottom left vertex and another angle of elevation of 53° at the bottom right vertex. The object on top of the building is at the vertex of the triangle. Point M and I on the diagram are points on the horizontal line of sight and on the ground respectively. We can label the diagram with the following values:Angle of elevation from point A = 66°Angle of elevation from point P = 53° Length of line segment AM = h Length of line segment MP = x Length of line segment IP = y Length of line segment MT = 50m. We'll use these values to calculate the length of h, which is the height of the building.Use the tangent ratio to find x:tan 66° = h / x => x = h / tan 66°. Use the tangent ratio to find y:tan 53° = h / y => y = h / tan 53°.We know that x + y = 50, so substituting the expressions for x and y from step 3 gives:h / tan 66° + h / tan 53° = 50h = 50 tan 66° tan 53° / (tan 53° + tan 66°) ≈ 78.63 m.Therefore, the height of the building is approximately 78.63 meters.
