a. The mass of the apple is approximately 33.879 grams.

b. The volume of the apple increases by approximately 1.454 cubic inches during the five-week period.

a. To find the mass of the apple, we need to calculate its volume first. The circumference of the apple can be used to determine its radius.

The formula for the circumference of a circle is C = 2πr,

where C is the circumference and r is the radius.

Rearranging the formula, we have r = C / (2π).

Plugging in the given circumference of 6 inches.

we get r = 6 / (2π) ≈ 0.955 inches.

Now, we need to convert the radius from inches to centimeters since the density is given in grams per cubic centimeter.

Since 1 inch is approximately 2.54 centimeters, the radius in centimeters is [tex]0.955 \times 2.54[/tex]  ≈ 2.427 cm.

Next, we can calculate the volume of the apple using the formula for the volume of a sphere: V = (4/3)πr³.

Plugging in the radius in centimeters, we get

V ≈ (4/3)π(2.427)³ ≈ 73.682 cm³.

Finally, we can find the mass of the apple by multiplying the volume by the density:

mass = volume [tex]\times[/tex] density

= 73.682 cm³ [tex]\times[/tex] 0.46 g/cm³

≈ 33.879 grams.

Therefore, the mass of the apple is approximately 33.879 grams.  

b. The volume of a sphere increases with the cube of its radius.

Since the radius increases by 1/8 inch per week for five weeks, the change in radius would be[tex](1/8) \times 5 = 5/8 inch.[/tex]

Now, let's calculate the change in volume during the five-week period. The formula for the volume of a sphere is V = (4/3)πr³.

Initially, the radius was 0.955 inches.

After five weeks, the radius would be 0.955 + 5/8 inches.

To compare the change in volume, we can calculate the new volume and find the difference:

Change in Volume = New Volume - Initial Volume

Initial Volume = (4/3)π(0.955)³

New Volume = (4/3)π(0.955 + 5/8)³

By subtracting the initial volume from the new volume, we can determine how the volume changes during the five-week period.

Please note that the exact calculation will depend on the precise values used for π and the measurements provided.

Option C. 5.5

Step-by-step explanation:

To solve for x in the equation:

[tex]\sf\implies\dfrac{3x - 4}{14} = \dfrac{9}{10}[/tex]

We need to isolate x on one side of the equation.

First, we simplify the left side by solving the division:

[tex]\sf\implies\dfrac{(3x - 4)}{14} = \dfrac{9}{10}[/tex]

Next, we cross-multiply to eliminate the fractions:

[tex]\sf\implies 10(3x - 4) = 14(9)[/tex]

[tex]\sf\implies 30x - 40 = 126[/tex]

Now, we isolate x by adding 40 to both sides of the equation:

[tex]\sf\implies 30x = 166[/tex]

Finally, we solve for x by dividing both sides of the equation by 30:

[tex]\sf\implies x = \dfrac{166}{30}[/tex]

[tex]\sf\implies x = 5.533[/tex]

Therefore, the value of x is approximately 5.533. Thus, the correct option is C. 5.5.

In which direction and by how many units should f(x) be shifted to match g(x): A. Left by 4 units.

In Mathematics and Geometry, the standard form of a quadratic function is represented by the following equation;

ax² + bx + c = 0

Based on the information provided about the parent quadratic function f(x), we can logically deduce that it is given by this equation;

f(x) = x²

Answer:

The point U' is (-6, -2).

Step-by-step explanation:

The reflection of point U over the x-axis is the point U' with the same x-coordinate but a y-coordinate that is the opposite of U's y-coordinate. Since the y-coordinate of point U is 3, the y-coordinate of the reflected point U' will be -3. Therefore, the coordinates of U' are (-2, -3).

The graph should show U at the point (2, 3) and U' at the point (2, -3) after being reflected over the x-axis.

Answer:  To estimate the value of csc 120° using the graph of y = csc x, we can locate the point on the graph that corresponds to 120° and read the y-coordinate (csc value) from there.

On the graph of y = csc x, we observe that the csc value is undefined at x = 0° and x = 180° due to vertical asymptotes. Additionally, csc x has maximum and minimum points at multiples of 90°.

To estimate csc 120°, we can look for the nearest maximum or minimum point on the graph. The closest maximum point to 120° is at 90°, and the closest minimum point is at 180°.

Since the maximum value of csc x is 1, we can estimate csc 120° to be approximately 1.

Therefore, the estimated value of csc 120° is 1 (rounded to the nearest tenth).

Saving for a down payment was worth it for Isabel. It reduces the total amount paid for the car by lowering the loan amount, resulting in less interest paid over time.

When evaluating whether saving for a down payment on a car was worth it for Isabel, we need to consider the difference in the total amount paid for the car in two scenarios: with a down payment and without a down payment. Let's analyze the two scenarios to make a judgment.

Scenario 1: With a down payment

In this scenario, Isabel saved up and made a down payment on the car. As a result, her monthly loan payment fits within her budget. By making a down payment, she reduces the principal amount borrowed and, subsequently, the interest charged on the loan.

The benefits of saving for a down payment include:

Lower loan amount: By making a down payment, Isabel reduces the total amount borrowed from the lender.

Reduced interest: With a lower loan amount, the interest charged on the loan is also reduced.

Shorter loan term: A down payment can help Isabel secure a shorter loan term, reducing the overall interest paid over time.

Scenario 2: Without a down payment

In this scenario, Isabel does not make a down payment and finances the entire purchase price of the car. As a result, her monthly loan payment may be higher, as she is borrowing a larger sum and potentially paying more interest over the loan term.

The drawbacks of not saving for a down payment include:

Higher loan amount: Without a down payment, the entire purchase price is financed, leading to a higher loan amount.

Increased interest: With a higher loan amount, more interest may accumulate over the loan term, resulting in a higher total cost of the car.

By comparing the two scenarios, we can assess the impact on the total amount paid for the car. Generally, having a down payment reduces the loan amount, decreases interest charges, and may result in a shorter loan term. This, in turn, can lead to substantial savings in the long run.

To determine the exact difference in the total amount paid for the car in each scenario, we would need specific details such as the purchase price of the car, the interest rate, and the loan term. With these figures, we could calculate the total cost of the car, including interest, in both scenarios and compare the results. Based on this analysis, we can then determine if saving for a down payment was worth it for Isabel.

In conclusion, saving for a down payment on a car can offer financial benefits such as lower loan amounts, reduced interest charges, and potentially shorter loan terms. Considering the potential cost savings and improved financial stability, it is generally advisable for Isabel to save for a down payment, making it worth the effort and consideration.

After 15 years, the amount in Hank's savings account, with no additional deposits or withdrawals, will be approximately $1,044.50.

To calculate the amount in Hank's savings account after 15 years with monthly compounding interest, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the future value of the account

P = the principal amount (initial deposit)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case:

P = $850

r = 1.2% = 0.012 (as a decimal)

n = 12 (monthly compounding)

t = 15 years

Plugging in the values into the formula, we get:

A = 850(1 + 0.012/12)^(12*15)

A = 850(1.001)^180

A ≈ 850 * 1.228824

A ≈ $1,044.50 (rounded to the nearest cent)

The value of x that satisfies the equation -8 + 5(2x + 1) = -(7x + 9) + x is x = 3/4.

To solve the equation -8 + 5(2x + 1) = -(7x + 9) + x, we will simplify the expression step by step and solve for the value of x.

Distribute 5 to the terms within the parentheses: -8 + 10x + 5 = -(7x + 9) + x

Combine like terms on both sides of the equation: -8 + 5 + 10x = -7x - 9 + x

Simplifying further, we have: -3 + 10x = -6x - 9

To eliminate the negative sign on the right side of the equation, we can multiply every term by -1: -3 + 10x = -6x - 9 * -1

This simplifies to: -3 + 10x = -6x + 9

Next, we want to isolate the x terms on one side of the equation and the constant terms on the other side. We can do this by adding 6x to both sides: -3 + 10x + 6x = -6x + 9 + 6x

Simplifying further: 16x - 3 = 9

To isolate the x term, we need to eliminate the constant term on the left side. We can do this by adding 3 to both sides: 16x - 3 + 3 = 9 + 3

Simplifying further: 16x = 12

Finally, we solve for x by dividing both sides of the equation by 16: (16x)/16 = 12/16

The equation simplifies to: x = 3/4

Step 1:  Isolate y in 4x + y = 16 by subtracting 4x from both sides to prepare for the substitution:

(4x + y = 16) - 4x

y = -4x + 16

Step 2:  Substitute this equation for y in the first equation to first solve for x:

6x + 5(-4x + 16) = 38

6x - 20x +80 = 38

-14x + 80 = 38

-14x = -42

x = 3

Step 3:  Plug in 3 for x in 4x + y = 16 to solve for y:

4(3) + y = 16

12 + y = 16

y = 4
