Complete question:

The volume of water displaced by the unknown mass (x) rock is 331 ml

What is meant by displaced?

Displaced means to be moved or forced out of its original position or location. It can refer to a physical object or a person who has been forced to leave their home or community due to conflict, natural disaster, or other circumstances. Displacement can cause significant challenges and disruptions to individuals and communities.

According to the given information

The formula for water displacement is: Volume (object) = Volume (water + object). This formula is based on Archimedes’ Principle, which states that the weight of the displaced fluid is equal to the weight of the submerged object1.

So, we can calculate the volume of water displaced by the unknown mass (x) rock as follows:

Volume (water + object) = 471 ml Volume (water) = 140 ml Volume (object) = Volume (water + object) - Volume (water) Volume (object) = 471 ml - 140 ml Volume (object) = 331 ml

Therefore, the volume of water displaced by the unknown mass (x) rock is 331 ml

It would be 360 ft shorter to walk along the diagonal path from A to C rather than walking along the edge of the park from A to C.

To find out how much shorter it would be to walk along the diagonal path from A to C, we need to compare the lengths of the two paths: the diagonal path and the path along the edge of the park.

First, we can use the Pythagorean theorem to find the length of the diagonal path. In the rectangle ABCD, diagonal AC is the hypotenuse of a right triangle with sides AB and BC. So:

AC² = AB² + BC²

AC² = (720 ft)² + (540 ft)²

AC² = 518400 + 291600

AC² = 810000

AC = √810000

AC = 900 ft

So the length of the diagonal path from A to C is 900 ft.

Next, we can find the length of the path along the edge of the park from A to C. This path consists of two sides of the rectangle: AB and BC. So:

Length of path from A to C = AB + BC

Length of path from A to C = 720 ft + 540 ft

Length of path from A to C = 1260 ft

So the length of the path along the edge of the park from A to C is 1260 ft.

To find out how much shorter it would be to walk along the diagonal path, we can subtract the length of the diagonal path from the length of the path along the edge of the park:

1260 ft - 900 ft = 360 ft

The closest ten thousand to 1,210,000 is 1,210,000 itself.

To find the lowest and largest number of people that could have visited London, we need to determine the range of possible values within which 1,210,000 falls.

If we round 1,210,000 to the nearest hundred thousand, we get 1,200,000. This means that the actual number of visitors could be up to 50,000 more than 1,200,000 or up to 10,000 less than 1,200,000.

Therefore, the lowest number of people that could have visited London is:

1,200,000 - 50,000 = 1,150,000

And the largest number of people that could have visited London is:

1,200,000 + 10,000 = 1,210,000

So the lowest number of people that could have visited London is 1,150,000, and the largest number is 1,210,000.

The equation of the hyperbola with centered at the origin has vertices at ( ±√7 , 0) and foci at (±√27 , 0) is (x²/7) - (y²/20) = 1.

Answer:

Sure. Here are the steps on how to calculate the interest and balance reduction for Poppy's first mortgage payment:

Calculate the monthly interest rate.

The monthly interest rate is calculated by dividing the annual interest rate by 12. In this case, the annual interest rate is 4.9%, so the monthly interest rate is:

monthly interest rate = 4.9% / 12 = 0.41%

Calculate the interest paid for the first month.

The interest paid for the first month is calculated by multiplying the monthly interest rate by the outstanding loan balance. In this case, the outstanding loan balance is $180,000, so the interest paid for the first month is:

interest paid = 0.41% * $180,000 = $738

Calculate the principal amount of the first payment.

The principal amount of the first payment is calculated by subtracting the interest paid from the monthly payment. In this case, the monthly payment is $955.31 and the interest paid is $738, so the principal amount of the first payment is:

principal amount = $955.31 - $738 = $217.31

Calculate the balance after the first payment.

The balance after the first payment is calculated by subtracting the principal amount from the outstanding loan balance. In this case, the outstanding loan balance is $180,000 and the principal amount of the first payment is $217.31, so the balance after the first payment is:

balance after first payment = $180,000 - $217.31 = $177,782.69

Therefore, the interest paid in month one is $738 and the balance reduced after the first payment is $217.31.

Given: $f(x) = \log(3x + 3 - 2x - 2)$

We need to prove that: $\frac{(a+b)^2}{f(a)+f(b)} = -4$

First, we need to simplify $f(x)$:

$f(x) = \log(x+1)$ (by simplifying the expression inside the log)

Now, we can rewrite the expression we need to prove as:

$\frac{(a+b)^2}{\log(a+1) + \log(b+1)} = -4$

Using the property of logarithms, we can rewrite this as:

$\log((a+1)(b+1)) = \log(e^{-4})$

Simplifying further:

$(a+1)(b+1) = e^{-4}$

Expanding the left side and simplifying:

$ab + a + b + 1 = e^{-4}$

Now, we can use the identity $(a+b)^2 = a^2 + 2ab + b^2$:

$(a+b)^2 = a^2 + 2ab + b^2$

Dividing both sides by $f(a)+f(b)$, which is $\log(a+1) + \log(b+1)$:

$\frac{(a+b)^2}{\log(a+1) + \log(b+1)} = \frac{a^2 + 2ab + b^2}{\log(a+1) + \log(b+1)}$

Using the property of logarithms again, we can simplify the denominator:

$\frac{(a+b)^2}{\log((a+1)(b+1))} = \frac{a^2 + 2ab + b^2}{\log((a+1)(b+1))}$

Substituting the value we derived earlier for $(a+1)(b+1)$:

$\frac{(a+b)^2}{\log(e^{-4})} = \frac{a^2 + 2ab + b^2}{\log(e^{-4})}$

Simplifying:

$(a+b)^2 = a^2 + 2ab + b^2$

$4ab = -4$

Dividing both sides by 4:

$ab = -1$

Therefore, we have shown that $\frac{(a+b)^2}{f(a)+f(b)} = -4$ if $f(x) = \log(3x+3-2x-2)$.

The total number of fluid ounces contained in 1 large glass of iced tea is 20 ounces

From the question, we are to calculate the total number of fluid ounces contained in 1 large glass of iced tea

Let the number of fluid ounces contained in 1 small glass be x

and

The number of fluid ounces contained in 1 large glass be y

Thus,

From the statement

"1 small glass and 2 large glasses contain a total of 48 fluid ounces of iced tea

2 small glasses and 3 large glasses contain a total of 76 fluid ounces of iced tea"

We can write that

x + 2y = 48

and

2x + 3y = 76

Now, we will solve the equations simultaneously

From the first equation,

x + 2y = 48

We can write that

x = 48 - 2y

Substitute into the second equation

2x + 3y = 76

2(48 - 2y) + 3y = 76

96 - 4y + 3y =76

96 - y = 76

96 - 76 = y

20 = y

Therefore,

y = 20

The graph shows a linear relationship where the value of the car decreases as time passes. We can see that after 0 years (when the car is brand new), its value is $30,000, and after 10 years, its value is $5,000.

We can use the slope-intercept form of a linear function (y = mx + b), where m is the slope and b is the y-intercept, to find the function that represents this relationship.

The slope is found by taking the difference in y-values (change in value) divided by the difference in x-values (change in time):

slope = (5000 - 30000) / (10 - 0) = -2500

The y-intercept is the value of the car when it is brand new, which is $30,000.

So, the equation of the line is:

y = -2500x + 30000

This matches the form of the equation y = -3000x + 27000, which is option (D), after we simplify it by combining the constants:

y = -3000x + 27000 = -2500x + 30000

Therefore, the function that best represents the relationship shown in the graph is y = -3000x + 27000.

By increasing the number of wire turns, using a thicker wire, increasing the battery voltage, and using a soft iron core, the student can enhance the electromagnet's strength, allowing it to pick up more paper clips.

To increase the number of paper clips the electromagnet will pick up, the student should take the following actions:

1. Increase the number of wire turns: By wrapping the wire around the iron nail more times, the student will create a stronger magnetic field. This is because each wire turn generates a magnetic field, and when the turns are in close proximity, their fields add up, creating a stronger overall field.

2. Use a thicker wire: A thicker wire will allow more current to flow through it, which will result in a stronger magnetic field. The higher the current, the more powerful the electromagnet becomes.

3. Increase the voltage of the battery: By increasing the voltage of the battery, the student can cause more current to flow through the wire. This will enhance the magnetic field, making the electromagnet more effective at picking up paper clips.

4. Use a soft iron core: Soft iron materials have higher magnetic permeability than other materials, meaning they can easily be magnetized and demagnetized. When the wire is wrapped around a soft iron nail, the resulting electromagnet will have a stronger magnetic field, thus improving its ability to pick up paper clips.

Combined audience = 112 million

x + y + z + u = 112 [Equation 1]

Other equations are,

y - z = z - u [Equation 2] ⇒ y + u = 2z

Substituting this in [Equation 1],

x + 3z = 112 [Equation 5]

x - y = 3(y - u) + 21 [Equation 3]

x - y + z - u = 28 [Equation 4]

x - y + y - z = 28

x - z = 28 [Equation 6]

Solving [Equation 5] and [Equation 6],

z = 21 and x = 49

Substituting, Equation 1 becomes,

y + u = 42

From Equation 3,

4y - 3u = 28

Solving these two equations,

u = 20 and y = 22

Hence x = 49 million, y = 22 million, z = 21 million and u = 20 million.

Belinda will need to invest $290,109.79 in the CD to earn a yearly income of $35,000 for 10 years.

The annual rate of interest that is charged on a loan or generated on an investment is known as the APR (Annual Percentage Rate), and it is stated as a percentage. Compounding, which is the practise of adding interest to the principal amount of a loan or investment, is not taken into account.

On the other hand, APY (Annual Percentage Yield) does consider the impacts of compounding. The annual percentage yield, or APY, is the rate of return that an investor receives on an investment over the course of a year. Both the interest gained on the initial sum and the interest earned on any prior interest that has been reinvested are considered.

The compound interest is given by the formula:

[tex]A = P * (1 + r/n)^{(n*t)}[/tex]

Now, isolating the value of P we have:

[tex]P = A / (1 + r/n)^{(n*t)}[/tex]

Now, substituting the value we have:

[tex]P = 35000 / (1 + 0.028/1)^{(1*10)} = $290,109.79[/tex]

Hence, Belinda will need to invest $290,109.79 in the CD to earn a yearly income of $35,000 for 10 years.
