Answer:
Diameter Length: ( About ) 5.4 km; Option B
Step-by-step explanation:
~ Let us apply the Area of the Circle formula πr^2, where r ⇒ radius of the circle ~
1. We are given that the area of the circle is 22.9 km^2, so let us substitute that value into the area of the circle formula, solving for r ( radius ) ⇒ 22.9 = π * r^2 ⇒ r^2 = 22.9/π ⇒ r^2 = 7.28929639361.... ⇒
radius = ( About ) 2.7
2. The diameter would thus be 2 times that of the radius by definition, and thus is: 2.7 * 2 ⇒ ( About ) 5.4 km
Diameter Length: ( About ) 5.4 km

To find:
The slope of the line that described by the data in the table.
Solution:
Consider any two points from the given table.
Let the two points are (0,8) and (4,13). So, the slope of the line is
\(m=\dfrac{y_2-y_1}{x_2-x_1}\)
\(m=\dfrac{13-8}{4-0}\)
\(m=\dfrac{5}{4}\)
\(m=1.25\)
Therefore, the slope of the line described by the data in the table is 1.25.

There were 432 million mobile users in India last year and it went up to 540 million mobile users this year. Find the percent increase.
The Percent increase in the number of mobile users in India from last year to this year is 25%.
The percent increase in the number of mobile users in India from last year to this year, we can use the following formula:
Percent Increase = (New Value - Old Value) / Old Value * 100
Given that there were 432 million mobile users last year and it increased to 540 million mobile users this year, we can substitute these values into the formula:
Percent Increase = (540 million - 432 million) / 432 million * 100
Simplifying the calculation:
Percent Increase = 108 million / 432 million * 100
Percent Increase = 0.25 * 100
Percent Increase = 25
Therefore, the percent increase in the number of mobile users in India from last year to this year is 25%.

4 minus (2X -3) = 3 what is x
Given the following equation:
\(4-(2x-3)=3\)You can solve for "x" by following these steps:
1. You must distribute the negative sign of the left side of the equation:
\(4-2x+3=3\)2. Now you need to add the like terms of the left side of the equation:
\(7-2x=3\)3. Apply the Subtraction property of equality by subtracting 7 from both sides of the equation:
\(\begin{gathered} 7-2x-(7)=3-(7) \\ -2x=-4 \end{gathered}\)4. Finally, you can apply the Division property of equality by dividing both sides of the equation by -2:
\(\begin{gathered} \frac{-2x}{-2}=\frac{-4}{-2} \\ \\ x=2 \end{gathered}\)The answer is:
\(x=2\)The original price for a piece of machinery is $150,000. If the piece of machinerydecreases in value by 22.5% each year, which graph models the value of the piece of machinery after x years?
The correct graph that models this exponential decay would show a decreasing trend as x (the number of years) increases. we need to consider the information given regarding its decrease in value.
The piece of machinery decreases in value by 22.5% each year. This means that its value after one year is \(100\% - 22.5\% = 77.5\%\) of its original value. In other words, its value is 0.775 times its original value.
To model the value of the machinery after x years, we need to consider the exponential decay function. The general form of an exponential decay function is:
y = \(a(1 - r)^x\)
Where:
- y represents the value after x years.
- a represents the initial value.
- r represents the decay rate (expressed as a decimal).
In this case, the initial value (a) is $150,000 and the decay rate (r) is 22.5% or 0.225.
Therefore, the equation representing the value of the piece of machinery after x years would be:
y = \(\$150,000 * (1 - 0.225)^x\)
Simplifying the equation further, we have:
y = \(\$150,000 * (0.775)^x\)
From this equation, we can see that the value of the machinery decreases exponentially over time. The correct graph that models this exponential decay would show a decreasing trend as x (the number of years) increases.

4 units
3 units
The length of A'B' = 5 units
The line segment AB is of 5 units. AB is then transformed through translation of 3 units to the right.
The translation only means change through a straight line. This transformation does not change the length of a line segment.
So the length of A'B' will also be 5 units.
But the position of A'B' will be different from that of AB on the co-ordinate plane. To be exactly, A'B' would be 3 units right to the position of AB on the co-ordinate plane.
Also the co-ordinates of A'B' will be different. Still their lengths will be same.

The amount the firm needs to deposit in the account now is 9,640.11. Given that the company has purchased a life truck with a useful life of 5 years, the maintenance costs for the truck during the first year are 2,000.
Also, maintenance costs are expected to increase at a rate of 300 per year over the remaining life, which is for four years. Assume that the maintenance costs occur at the end of each year.

An antecedent is a noun or pronoun that denotes a specific being, place, object, or clause.
It's also referred to as a referent. Without an antecedent, a sentence may be insufficient or nonsensical since it is

Expand the complex function f(z) = 1/z(z-2)² in a Laurent series about z = 0.
The series expansion will converge within a certain radius of convergence determined by the singularities of the function. In this case, the function has singularities at z = 0 and z = 2, so the series will converge within the annulus defined by 0 < |z| < 2.
To expand the complex function f(z) = 1/z(z - 2)² into a Laurent series about z = 0, we can use partial fraction decomposition and the geometric series expansion. Here's how we can proceed:
Step 1: Perform partial fraction decomposition
1/z(z - 2)² = A/z + B/(z - 2) + C/(z - 2)²
To find the constants A, B, and C, we can multiply both sides by z(z - 2)² and equate the coefficients of corresponding powers of z:
1 = A(z - 2)² + Bz(z - 2) + Cz
Expanding the right-hand side:
1 = A(z² - 4z + 4) + Bz² - 2Bz² + Cz
1 = (A + B)z² + (-4A - 2B + C)z + 4A
Comparing coefficients:
A + B = 0 (coefficient of z²)
-4A - 2B + C = 0 (coefficient of z)
4A = 1 (constant term)
Solving this system of equations, we get A = 1/4, B = -1/4, and C = 1/2.
Step 2: Substitute the values of A, B, and C back into the partial fraction decomposition:
1/z(z - 2)² = (1/4)/z - (1/4)/(z - 2) + (1/2)/(z - 2)²
Step 3: Expand each term using the geometric series expansion.
For (1/4)/z:
(1/4)/z = (1/4) * (1/z) = (1/4) * (1/(z - 0)) = 1/(4z) = 1/(4z) * (1/1)
Using the geometric series expansion:
1/(1 - w) = 1 + w + w² + w³ + ...
Where |w| < 1
Applying this to our term:
1/(4z) * (1/1) = (1/4z) * (1/(1 - (-z/4))) = (1/4z) * (1 + (-z/4) + (-z/4)² + (-z/4)³ + ...)
For (-1/4)/(z - 2):
(-1/4)/(z - 2) = (-1/4) * (1/(z - 2)) = (-1/4) * (1/(z - 2 - 0)) = -1/(4(z - 2)) = -1/(4(z - 2)) * (1/1)
Again, applying the geometric series expansion:
-1/(4(z - 2)) * (1/1) = (-1/(4(z - 2))) * (1/(1 - (z/4 - 1))) = (-1/(4(z - 2))) * (1 + (z/4 - 1) + (z/4 - 1)² + (z/4 - 1)³ + ...)
For (1/2)/(z - 2)²:
(1/2)/(z - 2)² = (1/2) * (1/(z - 2)²) = (1/2) * (1/(z - 2)² * (1/1)
Again, applying the geometric series expansion:
(1/2)/(z - 2)² * (1/1) = (1/2)/(z - 2)² * (1/(1 - (z/2 - 1))) = (1/2)/(z - 2)² * (1 + (z/2 - 1) + (z/2 - 1)² + (z/2 - 1)³ + ...)
Combining all the expanded terms, we get the Laurent series expansion of f(z) = 1/z(z - 2)² about z = 0:
f(z) = 1/(4z) - 1/(4(z - 2)) + 1/(2(z - 2)²) + ...

If the height of a cone is 14.7 and the radius is 2 what is the volume
Answer:
volume = 174.8 sq. units.
Answer:
61.5752159 units³
Step-by-step explanation:
The height of a cone can be found using the following formula:
\(v=\frac{1}{3} \pi r^2h\)
We know that the height is 14.7 and the radius is 2.
\(h=14.7 \\r=2\)
Substitute the values into the formula.
\(v=\frac{1}{3} \pi (2)^2(14.7)\)
Evaluate the exponent.
⇒ 2²= 2*2 = 4
\(v=\frac{1}{3} \pi (4)(14.7)\)
Multiply 4 and 14.7
\(v=\frac{1}{3} \pi (58.8)\)
Multiply 1/3 and pi.
\(v=1.04719755*58.8\)
Multiply the two numbers together.
\(v=61.5752159\)
Add appropriate units. Volume is cubic units, and we aren't given units. So, we should use cubic units.
\(v=61.5752159 units^3\)
The volume of the cone is 61.5752159 cubic units.
