Answer:

[tex]0.1212...=\dfrac{4}{33}[/tex]

Step-by-step explanation:

A repeating decimal is a decimal number with a digit (or group of digits) that repeats forever.

There are three ways to show a repeating decimal:

0.1212... is a repeating decimal as there are two duplicates of the repeating block of digits "12" followed by an ellipsis.

To express a repeating decimal as a rational number, begin by assigning the decimal to a variable:

[tex]x=0.1212...=0.\overline{12}[/tex]

Multiply both sides by 100:

[tex]\implies x \cdot 100=0.\overline{12}\cdot 100[/tex]

[tex]\implies 100x=12.\overline{12}[/tex]

Subtract the first equation from the second to eliminate the part after the decimal:

[tex]\begin{array}{crcr}& 100x & = & 12.\overline{12}\\- & x & = & 0.\overline{12}\\\cline{2-4} & 99x & = & 12\phantom{.12}\\\end{array}[/tex]

Divide both sides of the equation by 99:

[tex]\implies \dfrac{99x}{99}=\dfrac{12}{99}[/tex]

[tex]\implies x=\dfrac{12}{99}[/tex]

Reduce the fraction to is simplest form by dividing the numerator and denominator by 3:

[tex]\implies x=\dfrac{12 \div 3}{99 \div 3}=\dfrac{4}{33}[/tex]

[tex]\textsf{Therefore, $0.1212...$ expressed in the form of a rational number is\;$\dfrac{4}{33}$}.[/tex]

No, the number of sit-ups Anna does, is not proportional to the time she spends doing them.

When Anna starts doing sit-ups for her first triathlon, she does a sit-up every 22 seconds. But we know that as she gets tired, each sit-up takes longer and longer to do. The situps may take 40 seconds or 75 seconds as she gets more tired.

As we can see that there is no constant rate at which she gets tired and take more seconds to do sit-ups. In order to be proportional, the increasing or decreasing rate should be constant. We can see that the time she spends doing them is not increasing or decreasing at a constant rate along with the number of sit-ups she is doing.

To calculate the moment of inertia of an object, you need to know its mass and the distance it is from the axis of rotation. In this case, the object has a mass of 12 kg and is distributed 4 meters from the axis of rotation. The formula to calculate the moment of inertia is I = mr^2, where the moment of inertia, m is the mass, and r is the distance from the axis of rotation.

Using this formula, we can calculate the moment of inertia of the object:

I = 12 kg x (4 m)^2

I = 192 kgm^2

Therefore, the moment of inertia of the object is 192 kgm^2.
To calculate the moment of inertia for an object, you can use the following formula:

Moment of Inertia (I) = Mass (m) × Distance² (r²)

Given the object's mass is 12 kg and the mass is distributed 4 meters from the axis of rotation, we can plug these values into the formula:

I = 12 kg × (4 m)²

Now, we'll square the distance:

I = 12 kg × 16 m²

Finally, multiply the mass and the squared distance:

I = 192 kg·m²

So, the moment of inertia of the object is 192 kg·m².

Bank Balance  | Amount Owed

---------------------|-------------

-$150               | $150

-$325              | $325

-$275              | $275

To find the amount owed, we simply take the absolute value of each bank balance. The player who owes the greatest amount is the one with the largest absolute value bank balance. In this case, that would be Malcolm, who owes $325.

Step-by-step explanation:

The equation which can be used to determine the total amount, t, Frankie will have spent after m months on his cell phone plan is t = 30 + 45m.

Given that,

Frankie has a new cell phone plan.

He will pay a one-time activation fee of 30$, and 45$ each month.

One time activation fee = $30

Amount each month = $45

Amount for m months = 45m

Total amount for the plan = 30 + 45m

If t represents the total amount for the cell phone activation plan, the required equation can be written as,

t = 30 + 45m

Hence the required equation for the cell phone plan is t = 30 + 45m.

The standard deviation of rainy days in March is approximately 2.55 days.

To find the standard deviation of rainy days in March, we first need to determine the expected value or the mean number of rainy days in March.

The expected value of a binomial distribution can be found using the formula: E(X) = np, where X is the random variable representing the number of rainy days in March, n is the number of trials (days in March), and p is the probability of success (rain) on a given day.

In this case, n = 31 (number of days in March) and p = 0.3 (probability of rain on any given day in March). Therefore, the expected value of rainy days in March is

E(X) = np = 31 × 0.3 = 9.3

Next, we need to find the variance of the binomial distribution, which is given by the formula: Var(X) = np(1 - p).

Var(X) = 31 × 0.3 × (1 - 0.3) = 6.51

Finally, the standard deviation of rainy days in March is the square root of the variance:

SD(X) = √Var(X) = √6.51 ≈ 2.55

y' = 10x^4 - 12x^2 + (27/4)x^2

To find the derivative of the given function, y = 2x^5 - 4x^3 + (9/4)x^3, we can use the power rule and the sum rule of differentiation.

The power rule states that the derivative of x^n is nx^(n-1), where n is any real number.

Using the power rule, we can find the derivative of each term in the function:

dy/dx (2x^5) = 10x^4
dy/dx (-4x^3) = -12x^2
dy/dx ((9/4)x^3) = (27/4)x^2

Using the sum rule, we can add the derivatives of each term to find the derivative of the function:

dy/dx (y) = dy/dx (2x^5) + dy/dx (-4x^3) + dy/dx ((9/4)x^3)
dy/dx (y) = 10x^4 - 12x^2 + (27/4)x^2

To model the population of a city, we can use the formula:

f(x) = 1,596,000 * (1 + 0.035)^x

Where x is the number of years since 2020 and 0.035 represents the annual increase rate of 3.5%.

To model the population of a city, we need to take into account the initial population in 2020 and the annual increase rate of 3.5%. The annual increase rate of 3.5% means that the population is expected to grow by 3.5% every year from the previous year's population. To incorporate this growth rate into our model, we can use the formula for compound interest:

A = P * (1 + r)^t

Where A is the final amount, P is the initial amount, r is the annual interest rate, and t is the number of years. In our case, the final amount is the population after x years since 2020, the initial amount is the population in 2020 (1,596,000), the annual interest rate is 3.5%, and the number of years is x.

By substituting the values into the formula, we get:

f(x) = 1,596,000 * (1 + 0.035)^x

This formula can be used to calculate the expected population of the city for any year in the future. For example, if we want to know the population in 2025, we can substitute x = 5 into the formula:

f(5) = 1,596,000 * (1 + 0.035)^5

= 1,825,854

Therefore, we can expect the population of the city to be around 1,825,854 in 2025, assuming the same annual increase rate of 3.5%.

To prove that 1/xy = 1/x * 1/y, we can start by multiplying both sides of the equation by xy.

Multiplying both sides of the equation by xy gives us:

1 = xy * 1/x * 1/y

Next, we can simplify the right-hand side by canceling out the x and y terms that appear in both the numerator and denominator:

1 = y/x + x/y

To further simplify this expression, we can multiply both sides by xy:

xy = y^2 + x^2

This equation can be rearranged to get:

x^2 + y^2 = xy

Finally, we can use the formula for the sum of squares:

x^2 + y^2 = (x+y)^2 - 2xy

Substituting this into the previous equation, we get:

(x+y)^2 - 2xy = xy

Simplifying, we get:

(x+y)^2 = 3xy

Taking the square root of both sides, we get:

x+y = sqrt(3xy)

Dividing both sides by xy, we get:

1/xy = 1/x * 1/y

Therefore, we have proven that 1/xy = 1/x * 1/y.
