Step 1: Calculate the volume of the water in the first container.

The volume of a cylinder is V = πr^2h, where r is the radius of the cylinder and h is the height of the cylinder.

Therefore, the volume of the water in the first container is V = πr^2 x 15 cm, where r is the given radius of the container.

Step 2: Calculate the height of the water in the second container.

The volume of the water in the second container is the same as the volume of the water in the first container, since the same quantity of water is being poured from one container to the other.

Therefore, the volume of the water in the second container is also V = πr^2 x 15 cm, where r is now 2r, the radius of the second container.

To find the height of the water in the second container, we can substitute the value of the radius into the equation for the volume and solve for h. This gives us h = (15 cm) / (π(2r)^2), which simplifies to h = 15 cm / 4πr^2.

The left Riemann sum approximation is 14.892

From the question, we have the following parameters that can be used in our computation:

f(x) = 3^x

The left Riemann sum can be expressed as:

[tex]R_n = h \sum_{i=1}^{n} \frac{4}{a + ih}[/tex]

Such that:

h = (b - a)/n

In this case, a = 2, b = 3.5, n = 3, and f(x) = 3^x

So, the left Riemann sum approximation is:

Approximation = (3.5-2)/3 * (f(2 + 1/3 * (3.5-2)) + f(2 + 2/3 * (3.5-2)) + f(2 + 3/3 * (3.5-2)))

Approximation = 0.5/3 * (3^(2 + 1/3 * (3.5-2)) + 3^(2 + 2/3 * (3.5-2)) + 3^(2 + 3/3 * (3.5-2)))

Answer:

x≥−1

Step-by-step explanation:

The domain of the inverse of a function is the range of the original function. The range of the cubic root function is y≥−1, so the domain of its inverse would be x≥−1.

Answer:

x≥−1, x is greater than or equal to negative 1

Step-by-step explanation:

The inverse of a function switches the roles of x and y, making the original range the new domain and the original domain the new range. In this case, the original domain is x≥7 and the range is y≥−1, so the inverse has a domain of y≥−1 and a range of x≥7 :)

The value of sin(x) in terms of cos(x) is √1 - cos²(x). The value of sin(x) is 3/5.

Since x is an angle in the second quadrant, sin(x) is positive and cos(x) is negative.

To write sin(x) in terms of cos(x), we can use the identity sin²(x) + cos²(x) = 1 and solve for sin(x):

                                sin²(x) + cos²(x) = 1

                                sin²(x) = 1 - cos²(x)

                                sin(x) = ± √(1 - cos²(x))

Since sin(x) is positive in the second quadrant, we have:

                               sin(x) = √(1 - cos²(x))

To show that cos(x) = -4/5, we can use the given equation:

                               3sin(x) - 4cos(x) = 5

We can rearrange this equation to get cos(x) on one side:

                              4cos(x) = 3sin(x) - 5

                              cos(x) = (3sin(x) - 5) / 4

Now we can substitute the expression for sin(x) that we found earlier:

                              cos(x) = (3√(1 - cos²(x)) - 5) / 4

Multiplying both sides by 4 and simplifying, we get:

                              4cos²(x) + 3cos(x) - 4 = 0

This is a quadratic equation in cos(x). We can solve it using the quadratic formula:

                             cos(x) = [-3 ± √(3² - 4(4)(-4))] / (2(4))

                             cos(x) = (-3 ± 7) / 8

                             cos(x) = 1/2 or cos(x) = -4/5

Since x is in the second quadrant, we have cos(x) < 0, so cos(x) = -4/5.

Finally, we can use the expression for sin(x) that we found earlier to get:

                            sin(x) = √(1 - cos²(x))

                            sin(x) = √(1 - (-4/5)²)

                            sin(x) = √(1 - 16/25)

                            sin(x) = √9/25

                            sin(x) = 3/5

Therefore, the exact value of sin(x) is 3/5.

Answer:

We can start by using logarithmic properties. If a, b, and c are positive numbers, then:

loga^b = b * loga

Using this property, we can rewrite the expression as:

x^(logy - logz) * y^(logz - logx) * z^(logx - logy) = x^(logy/logx - logz/logx) * y^(logz/logy - logx/logy) * z^(logx/logz - logy/logz)

Using the change-of-base formula, we can simplify the exponents:

x^(logy/logx - logz/logx) = (logy/logx) / (logz/logx) = logy/logz

Similarly,

y^(logz/logy - logx/logy) = logz/logx

and

z^(logx/logz - logy/logz) = logx/logy

Now, we can substitute these results back into the original expression:

x^(logy - logz) * y^(logz - logx) * z^(logx - logy) = logy/logz * logz/logx * logx/logy

By the transitive property of logarithms, we have:

logy/logz * logz/logx * logx/logy = logy/logx

Finally, using the change-of-base formula again, we can simplify this result:

logy/logx = y^(1/logx) / x^(1/logx)

Since y and x are positive numbers, their exponents must also be positive. Therefore, we have:

y^(1/logx) / x^(1/logx) = 1

So,

x^(logy - logz) * y^(logz - logx) * z^(logx - logy) = 1

And we have proven that the expression is equal to 1.

Combinations are methods for choosing elements from collections of objects. Unlike permutations, selection order is unimportant. The number of combinations can be counted in simpler situations.  

The formula for combinations is given by

Here we have

Number of tosses = 12 times

The number of heads is between 7 and 11 inclusive    

Number of ways of getting 7 heads and 5 tails

= 12! / (7!5!) = 792  

Number of ways of getting 8 heads and 4 tails

= 12!/(8!4!) = 495    

Number of ways of getting 9 heads and 3 tails

= 12!/(9!3!) = 220  

Number of ways of getting 10 heads and 2 tails

= 12!/ (10!2!) = 66

Number of ways of getting 11 heads and 1 tail

= 12! / (11!1!) = 12  

Total number of ways = 792 + 495 + 220 + 66 + 12

The range of values in which at least 88.89% of the fake prices will lie if the standard deviation is $53,500 will be  $84,600 and $391,600.

What does standard deviation mean in plain English?

The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean.

                         Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high.

The lower boundary of the range is calculated by subtracting two standard deviations from the average sale price

$238,100 - $53,500 = $84,600

The upper boundary of the range is calculated by adding two standard deviations to the average sale price

$238,100 + $53,500 = $391,600

Answer:

Step-by-step explanation:

You want to know the total paid during the first year of a $1.8M loan at 9% if the balance is reduced by $140,000 after 12 monthly payments. You also want to know the amount of the monthly payment.

The remaining balance of an amortized loan is given by the formula ...

  FV = PV(1 +r)^n - <future value of payments>

where r is the monthly interest rate, and n is the number of months.

Using the given loan values, we have ...

  1,800,000 -140,000 = 1,800,000(1 +0.09/12)^12 -<payment value>

Solving for the future value of the payments, we find ...

  <payment value> = 1,800,000(1.093806898) -1,660,000 = 308,852.42

This is the future value of the payments made, so some further calculation is required to find the amount of the payment.

  <payment future value> = P((1+r)^n -1)/r = P(1.0075^12 -1)/0.0075

  P = <payment future value>/12.5075864

  P = 308,852.42/12.5075864 = 24693.21

The amount of the monthly payment was $24,693.21.

12 monthly payments were made in the first year, so the total paid was ...

  12 × $24,693.21 = $296,318.52 . . . . total paid in the first year

Answer:

Sarah purchased 2 first class tickets and 5 coach tickets.

Step-by-step explanation:

Let's call the number of first class tickets purchased "x".

The number of coach tickets purchased would be 7-x.

We know that the total spent on first class tickets was $1170 * x and the total spent on coach tickets was $320 * (7-x).

The total budget was $3940, so we can set up the following equation:

$1170 * x + $320 * (7-x) = $3940

Expanding the right side:

$1170 * x + $320 * 7 - $320 * x = $3940

Combining like terms:

$800 * x = $3940 - $320 * 7

Subtracting $320 * 7 from both sides:

$800 * x = $3940 - $2240

$800 * x = $1700

Dividing both sides by 800:

x = 2.125

Since x must be a whole number, Sarah purchased 2 first class tickets and 5 coach tickets.

Therefore , if we know the measures of the angles θ1 and θ2 in degrees, we can use equations (1) and (2) to find their difference, α - β.

An angle in Euclidean space is a shape made up of two poles that divide at the centre, or apex, of the structure. These beams are referred to as the sides or loops. When two rays are combined, there may be an inclination inside this surfaces where they are situated. Angles can also be created by combining two surface.

Here,

Since the two angles share the same terminal side, they are coterminal angles. This means that they differ by an integer multiple of 360 degrees or 2π radians.

Let the two angles be θ1 and θ2. Then we can express them as:

θ1 = k(360°) + α (1)

θ2 = k(360°) + β (2)

where k is an integer and α and β are the measures of the angles in degrees, such that 0° ≤ α, β < 360°.

Since the angles share the same terminal side, they must add up to 360 degrees or 2π radians. So we have:

θ1 + θ2 = k(360°) + α + k(360°) + β = 360° (3)

Simplifying equation (3), we get:

θ1 + θ2 = 2k(360°) + α + β = 360°

α + β = 360° - 2k(360°) = 360°(1 - 2k)

Therefore, the sum of the two angles α and β is equal to 360 degrees times an integer 1-2k.

To find the difference between the two angles, we can subtract equation (2) from equation (1):

θ1 - θ2 = (k(360°) + α) - (k(360°) + β) = α - β

Therefore, the difference between the two angles is equal to the absolute value of the difference between their measures in degrees:

|α - β| = |θ1 - θ2|

Note that since the angles are coterminal, their measures differ by an integer multiple of 360 degrees, so the difference between their measures can be found by subtracting one from the other and taking the result modulo 360. That is:

α - β = (θ1 - θ2) mod 360°

So if we know the measures of the angles θ1 and θ2 in degrees, we can use equations (1) and (2) to find their difference, α - β.

The initial payment for the first 3 years of an interest-only loan for a $141,000 5/130-year ARM at 5% would be $7050.

An ARM, or Adjustable Rate Mortgage, is a type of mortgage loan where the interest rate can change over time. The 5/1 in the loan term "5/130-year ARM" means that the initial rate is fixed for the first 5 years and can change once every year thereafter for the remaining life of the loan (in this case, 130 years).

For an interest-only loan, the borrower pays only the interest due on the loan for a set period of time, in this case, the first 3 years. The interest payment can be calculated as:

Interest payment = Loan amount * Interest rate

The loan amount in this case is $141,000 and the interest rate is 5%, so the interest payment is:

Interest payment = $141,000 * 0.05 = $7050

So, the initial payment for the first 3 years of an interest-only loan for a $141,000 5/130-year ARM at 5% would be $7050.
