be 6 and 8. Larry states that the first factors in the tree
should be 4 and 12. Trish states that the initial factors of
48 do not affect the prime factorization. Explain why Trish
is correct.
Answer:
students need to produce a prime factorization of 48. Donna states that the first factors in the tree should be 6 and 8. Larry states that the first factors in the tree should be 4 and 12. Trish states that the initial factors of 48 do not affect the prime factorization. Explain why Trish is correct.Trish is correct because the initial factors of 48 do not affect the prime factorization. Prime factorization is the process of breaking down a composite number into its prime factors. The prime factors of a number are those factors that are prime numbers. The prime factorization of 48 is 2 x 2 x 2 x 2 x 3, which means that 48 can be expressed as a product of these prime factors. The order in which we choose the initial factors to start the prime factorization does not affect the result, as long as we continue to break down the resulting factors into their prime factors until we cannot break them down any further. Therefore, Trish is correct that the initial factors of 48 do not affect the prime factorization.
Trish is correct because the prime factorization of 48 will be the same regardless of which factors are chosen as the initial factors in the tree.
To see why, let's look at the prime factorization of 48:
48 = 2 × 2 × 2 × 2 × 3
No matter which factors are chosen as the initial factors, the same prime factors will eventually be found.
For example, if Donna's method is used, we could start with 6 and 8:
6 = 2 × 3
8 = 2 × 2 × 2
Then we could continue to factor each of these numbers until we reach prime factors:
6 = 2 × 3
8 = 2 × 2 × 2
= 2 × 2 × 2 × 3
= 2³ × 3
Now we have found all of the prime factors of 6 and 8, and we can combine them to get the prime factorization of 48:
48 = 2 × 2 × 2 × 2 × 3
If Larry's method is used, we could start with 4 and 12:
4 = 2 × 2
12 = 2 × 2 × 3
Then we could continue to factor each of these numbers until we reach prime factors:
4 = 2 × 2
12 = 2 × 2 × 3
= 2² × 3
Now we have found all of the prime factors of 4 and 12, and we can combine them to get the prime factorization of 48:
48 = 2 × 2 × 2 × 2 × 3
As we can see, the same prime factors are found regardless of which factors are chosen as the initial factors in the tree. Therefore, Trish is correct that the initial factors of 48 do not affect the prime factorization.
A bond is worth $100 and grows in value by 4 percent each year. Explain why the value of the bond after t years is given by 100•1.04^t
The value of the bond is multiplied by the factor [tex](1 + 0.04)[/tex], which is the same as multiplying by 1.04. After t years, the value of the bond will be multiplied by this factor t times, giving the formula:
[tex]100(1.04)t[/tex].
So, the value of the bond after t years is given by 100 • 1.04t.
What is a factor?A factor in mathematics is an expression or number that divides another expression or number without producing a residue. In other terms, a factor is a unit of measurement that may be multiplied by another unit of measurement to yield a specific outcome.
For example, 2 and 3 are factors of 6, because 2 multiplied by 3 equals 6. Similarly, (x + 1) and (x - 3) are factors of the expression [tex]x^2 - 2x - 3[/tex], because when these factors are multiplied together, they produce the expression:
[tex](x + 1) \times (x - 3) = x^2 - 2x - 3[/tex]
The bond is worth $100 initially, and it grows in value by 4% each year. This means that after one year, the value of the bond will be:
[tex]100 + 0.04(100) = 100(1 + 0.04) = 100(1.04)[/tex]
In other words, the value of the bond after one year is the initial value (100) multiplied by a factor of 1.04.
Similarly, after two years, the value of the bond will be:
[tex]100(1.04) + 0.04(100)(1.04) = 100(1.04)^2[/tex]
After three years, the value of the bond will be:
[tex]100(1.04)^2 + 0.04(100)(1.04)^2 = 100(1.04)^3[/tex]
In general, after t years, the value of the bond will be:
[tex]100(1.04)t[/tex]

Help pls
Using the derivative of the velocity, the average value of the position function from t = 2 seconds to t = 5 seconds is 14.5.
What is the position and average value of the position function from t = 2 to t = 5?Given:
Acceleration function, a(t) = 2sin(t) + 1
Initial velocity, v(0) = 0
Initial position, s(0) = 3
To find:
Velocity function, v(t)
Position function, s(t)
Average value of the position function from t = 2 seconds to t = 5 seconds
Solution:
We know that acceleration is the derivative of velocity, and velocity is the derivative of position. So we can find the velocity and position functions by integrating the acceleration function.
Velocity function:
[tex]v(t) = \int a(t) dt\\v(t) = \int (2sin(t) + 1) dt\\v(t) = -2cos(t) + t + C1[/tex]
We know that the initial velocity, v(0) = 0. Substituting this value in the above equation, we get:
[tex]0 = -2cos(0) + 0 + C1\\C1 = 2[/tex]
Therefore, the velocity function is:
[tex]v(t) = -2cos(t) + t + 2[/tex]
Position function:
[tex]s(t) = \int v(t) dt\\s(t) = \int (-2cos(t) + t + 2) dt\\s(t) = 2sin(t) + \frac{1}{2} t^2 + 2t + C2[/tex]
We know that the initial position, s(0) = 3. Substituting this value in the above equation, we get:
[tex]3 = 2sin(0) + 0 + 0 + C2\\C2 = 3\\[/tex]
Therefore, the position function is:
[tex]s(t) = 2sin(t) + \frac{1}{2} t^2 + 2t + 3[/tex]
Average value of the position function from t = 2 seconds to t = 5 seconds:
We can find the average value of the position function using the following formula:
[tex]Avg = (1/(b-a)) * \int(a,b) f(t) dt[/tex]
Here, a = 2 and b = 5. So, substituting the values in the above formula, we get:
[tex]Avg = (1/(5-2)) * \int(2,5) (2sin(t) + \frac{1}{2} t^2 + 2t + 3) dt\\Avg = \frac{1}{3} * [ -2cos(t) + 1/6 t^3 + t^2 + 2t ] \eval(2,5)\\[/tex]
[tex]Avg = \frac{1}{3} * [ (-2cos(5) + 1/6 (5^3) + 5^2 + 25) - (-2cos(2) + 1/6 (2^3) + 2^2 + 22) ]\\Avg = 14.5[/tex]
Therefore, the average value of the position function from t = 2 seconds to t = 5 seconds is 14.5.

2/15 ÷ 3/415/2 ÷ 3/42/15 ÷ 4/515/2 ÷ 4/315/2 ÷ 3/4find the sum of money that amounts to Rs- 3450 in 4 monts at the rate of 4½ %. per annam.
Answer:
To find the sum of money that amounts to Rs- 3450 in 4 months at the rate of 4.5% per annum, we can use the formula for simple interest:
Simple Interest = (Principal * Rate * Time) / 100
Where,
Principal = the sum of money borrowed or invested
Rate = the rate of interest per annum
Time = the time period in years
Since the time period given is 4 months, we need to convert it to years by dividing it by 12:
Time = 4/12 years = 1/3 years
Now, we can plug in the given values and solve for Principal:
Simple Interest = (Principal * Rate * Time) / 100
3450 = (Principal * 4.5 * 1/3) / 100
3450 * 100 = Principal * 4.5 * 1/3
11500 = Principal * 1.5
Principal = 11500 / 1.5
Principal = 7666.67 (rounded off to two decimal places)
Therefore, the sum of money that amounts to Rs- 3450 in 4 months at the rate of 4.5% per annum is Rs- 7666.67.

the composition of transformations that map ABCD to EHGF is a reflection over the y-axis followed by a translation by (4,7).
What is axis reflection ?
An axis reflection is a transformation in geometry that involves reflecting a point, a line, or an object across a given axis. In two dimensions, there are two axes of reflection: the x-axis and the y-axis.
When reflecting over the x-axis, all points stay in the same horizontal position but change their vertical position, so a point (x,y) is reflected to (x,-y).
When reflecting over the y-axis, all points stay in the same vertical position but change their horizontal position, so a point (x,y) is reflected to (-x,y).
Axis reflections can be used to transform geometric shapes such as polygons, circles, or lines. These transformations have important applications in various fields, including physics, engineering, computer graphics, and art.
To find the composition of transformations that map ABCD to EHGF, we first need to determine the individual transformations that are needed.
Reflecting over the y-axis will change the x-coordinates of the points, but leave the y-coordinates unchanged. So, to reflect over the y-axis, we negate the x-coordinates of the points.
The translation (x+4, y+7) will move each point 4 units to the right and 7 units up.
Therefore, the composition of transformations is:
Reflect over the y-axis by negating the x-coordinates:
A'(-2, 3), B'(-4, 2), C'(-4, 0), D'(-2, -1)
Translate by (4,7):
A''(2, 10), B''(0, 9), C''(0, 7), D''(2, 6)
Therefore, the composition of transformations that map ABCD to EHGF is a reflection over the y-axis followed by a translation by (4,7).

The value of the expression is 38 when z = 17.
What is the value of this expression when z = 17?Given that, an algebraic expression is described as 14 more than the product of 3 and the difference of z and 9.
First, we write the expression:
The difference of z and 9 means we subtract 9 from z. We then take this result and multiply it by 3.
Finally, we add 14 to the product of 3 and the difference of z and 9.
3(z - 9) + 14
Where z represents the value that we want to substitute into the expression.
Substituting z = 17, we get:
3(z - 9) + 14

The ratio of monthly income to the monthly saving of a family is 9:2. If the
saving is Rs 4,320, find the income and expenditure of the family.
Step-by-step explanation:
Let's assume that the monthly income of the family is x.
From the problem statement, we know that the ratio of monthly income to the monthly saving is 9:2.
Therefore, we can write:
x/4320 = 9/2
To solve for x, we can cross-multiply:
2x = 9*4320
2x = 38,880
x = 19,440
So, the monthly income of the family is Rs 19,440.
To find the monthly expenditure, we can subtract the monthly savings from the monthly income:
Monthly expenditure = Monthly income - Monthly saving
Monthly expenditure = 19,440 - 4,320
Monthly expenditure = 15,120
Therefore, the monthly expenditure of the family is Rs 15,120

The attendance at Longwood middle school his first football game of the season is 437 people eat it at the second game is 4 to 76 people determine the approximate percent increase in attendance between the first and second game round your answer to the nearest 10th%
Approximate percent increase in attendance between the first and second game is 8.9%.
What is the approx. percentage increase in attendance between the first and second football games?
To calculate the percent increase in attendance between the first and second game, we can use the formula:
percent increase =
[(new value - old value) / old value] x 100%
where the old value is the attendance at the first game and the new value is the attendance at the second game.
Substituting the given values, we get:
percent increase = [(476 - 437) / 437] x 100%
percent increase = (39 / 437) x 100%
percent increase ≈ 8.92%
Rounding to the nearest tenth percent, we get the approximate percent increase in attendance between the first and second game as 8.9%.

Finding the total volume of a composite figure requires breaking it down into simpler shapes and then adding up their volumes.
How to find the volume of a composite figure>To find the total volume of a composite figure, you'll need to break it down into simpler shapes and calculate their individual volumes.
Then, you can add up these volumes to get the total volume of the composite figure.
Here are the general steps you can follow:
Identify the simpler shapes: Look for the individual shapes that make up the composite figure, such as cubes, rectangular prisms, pyramids, cylinders, or spheres.
Calculate the volume of each shape: Use the appropriate formula for each shape to find its volume. For example, the volume of a cube is calculated by multiplying the length, width, and height of the cube.
Add up the volumes of all the simpler shapes: Once you have found the volume of each simpler shape, add them up to get the total volume of the composite figure.
Adjust for overlapping shapes: If there are any overlapping shapes, subtract the volume of the overlapped portion to avoid double-counting.
Check your work: Double-check your calculations and make sure your final answer makes sense based on the dimensions of the composite figure.
Overall, finding the total volume of a composite figure requires breaking it down into simpler shapes and then adding up their volumes.

The mean per capita income is 21,699
dollars per annum with a standard deviation of 835
dollars per annum.
What is the probability that the sample mean would be less than 21583
dollars if a sample of 399
persons is randomly selected? Round your answer to four decimal places.
The probability that the sample mean would be less than 21583 dollars if a sample of 399 persons is randomly selected is approximately 0.0826 or 8.26% (rounded to four decimal places).
What is probability?
Probability is a way to gauge how likely something is to happen. It is a number between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty that the occurrence will occur.
We can use the central limit theorem (CLT) to approximate the sampling distribution of the sample mean. According to CLT, if we have a large enough sample size (n≥30), the sampling distribution of the sample mean will be approximately normal, regardless of the underlying distribution of the population.
The mean of the sampling distribution of the sample mean is the same as the population mean, which is given as μ = 21699 dollars per annum. The standard deviation of the sampling distribution of the sample mean is equal to the standard error of the mean (SEM), which is calculated as follows:
SEM = σ/√n, where n is the sample size, and is the total standard deviation.
With the numbers from the problem substituted, we obtain:
SEM = 835/√399 = 41.767
Now, we need to find the probability that the sample mean would be less than 21583 dollars. We can standardize the sample mean using the standard normal distribution as follows:
z = (x - μ) / SEM, where the sample mean is x.
Substituting the values, we get:
z = (21583 - 21699) / 41.767 = -1.389
Using a standard normal distribution table, we can find that the area to the left of z=-1.389 is 0.0826.
Therefore, the probability that the sample mean would be less than 21583 dollars if a sample of 399 persons is randomly selected is approximately 0.0826 or 8.26% (rounded to four decimal places).

Answer:
Step-by-step explanation:
As seen in earlier sections, the process of completing the square is a useful tool in finding noninteger values of quadratic equations, especially intercepts. When a quadratic equation of the
form f (x) = ax2
+ bx + c is put through the process of completing the square it yields an
equation of the form f (x) = a(x – h)2
+ k . The conversion of the equation to this form will
yield critical information about the equation’s characteristics before you begin to graph it.
1.) The value of h is the distance left (if negative) or right (if positive) the graph
translates from the standard position.
2.) The value of k is the distance up (if positive) or down (if negative) the graph
translates from the standard position.
3.) The values of h and k, when put together as an ordered pair, give the vertex i.e.
(h, k).
4.) The equation x = h is the formula for the axis of symmetry.
The following example demonstrates how to find the following critical information of the
equation:
a.) vertex
b.) axis of symmetry
c.) y intercept (if any)
d.) x intercepts (if any)

A restaurant borrows $15,700 for two months from a nearby bank. For this loan, the neighbourhood bank charges simple interest at a yearly rate of 10%. Suppose a month is one-twelfth of a year.
a) $218.06 in interest will be due after two months.
b) In the event that the restaurant doesn't pay, the balance due after two months is $15,918.06.
a) To find the interest that will be owed after 2 months, we first need to calculate the monthly interest rate:
r = (10%)/12 = 0.00833333...
We can use the formula for simple interest to find the interest owed:
I = Prt
where P is the principal (the amount borrowed), r is the interest rate per period, and t is the time in periods. Since the loan is for 2 months, we have t = 2/12 = 1/6 years.
Substituting the values, we get:
I = 15700 * 0.00833333... * (1/6) = 218.0555...
Rounding to the nearest cent, the interest owed after 2 months is $218.06.
b) The total amount owed after 2 months is the sum of the principal and the interest. Using the same values as above, we have:
The total amount owed = Principal + Interest
= 15700 + 218.0555...
= 15918.0555...
Rounding to the nearest cent, the amount owed after 2 months is $15,918.06.
The complete question is:-
A restaurant borrows $15700 from a local bank for 2 months. the local bank charges simple interest at an annual rate of 10% for this loan. assume each month is 1/12 of a year. answer each below. do not round any intermediate computations, and round your final answers to the nearest cent, if necessary, refer to the lists of financial formulas.
