The statement is true because 4 × 30%=120
How to solve if the statement is trueIn the first month, the price of the avocado is said to have been raised by 30 percent.
While already raised by 30 percent, another 30 percent raise would make the increase to be 60 percent.
While is at 60 percent, the third month the raise would be = 90 percent because 30 * 3 = 90
Then at 90 percent if there is another raise of 30 percent, the increase would grow to be 120 percent.

Let take the common factor first
\(\frac{2}{3}\lim _{x\to\infty}\frac{x^2(x-3)}{x^2(1-2x)}\)Let's apply algebraic property:
\(a+b=a(1+\frac{b}{a})\)\(\begin{gathered} \frac{2}{3}.\lim _{x\to\infty}\frac{x^2(x-3)}{x^2(1-2x)} \\ \\ \frac{2}{3}.\lim _{x\to\infty}\frac{x^2x(1-\frac{3}{x})}{x^2x(\frac{1}{x}-2)} \\ \\ x^2x\text{ can divide each other } \\ \\ \frac{2}{3}.\lim _{x\to\infty}\frac{(1-\frac{3}{x})}{(\frac{1}{x}-2)} \end{gathered}\)Let take the limit of the numerator

Answer:
\(f_x(x,y,z)=4\sin (y-z)\)
\(f_x(x,y,z)=4x\cos (y-z)\)
\(f_z(x,y,z)=-4x\cos (y-z)\)
Step-by-step explanation:
The given function is
\(f(x,y,z)=4x\sin (y-z)\)
We need to find first partial derivatives of the function.
Differentiate partially w.r.t. x and y, z are constants.
\(f_x(x,y,z)=4(1)\sin (y-z)\)
\(f_x(x,y,z)=4\sin (y-z)\)
Differentiate partially w.r.t. y and x, z are constants.
\(f_y(x,y,z)=4x\cos (y-z)\dfrac{\partial}{\partial y}(y-z)\)
\(f_y(x,y,z)=4x\cos (y-z)\)
Differentiate partially w.r.t. z and x, y are constants.
\(f_z(x,y,z)=4x\cos (y-z)\dfrac{\partial}{\partial z}(y-z)\)
\(f_z(x,y,z)=4x\cos (y-z)(-1)\)
\(f_z(x,y,z)=-4x\cos (y-z)\)
Therefore, the first partial derivatives of the function are \(f_x(x,y,z)=4\sin (y-z), f_x(x,y,z)=4x\cos (y-z)\text{ and }f_z(x,y,z)=-4x\cos (y-z)\).

A study of a local high school tried to determine the mean amount of money that each
student had saved. The study surveyed a random sample of 69 students in the high
school and found a mean savings of 5000 dollars with a standard deviation of 1400
dollars. At the 95% confidence level, find the margin of error for the mean, rounding
to the nearest whole number. (Do not write ).
Using the t-distribution, it is found that the margin of error for the 95% confidence interval is of $336.
What is a t-distribution confidence interval?The confidence interval is:
\(\overline{x} \pm t\frac{s}{\sqrt{n}}\)
In which:
\(\overline{x}\) is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The margin of error is given by:
\(M = t\frac{s}{\sqrt{n}}\)
The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 69 - 1 = 68 df, is t = 1.9955.
The standard deviation and sample size are given, respectively, by:
s = 1400, n = 69.
Hence, the margin of error in dollars is given by:

Answer:
Step-by-step explanation:
Hexagon DEFGHI is translated on the coordinate plane below to create hexagon D′E′F′G′H′I′: Hexagon DEFGHI and Hexagon D prime E prime F prime G prime H prime I prime on the coordinate plane with ordered pairs at D 2, 5, at E 5, 5, at F 6, 3, at G 5, 1, at H 2, 1, at I 1, 3, at D prime negative 6, negative 2, at E prime negative 3, negative 2, at F prime negative 2, negative 4, at G prime negative 3, negative 6, at H prime negative 6, negative 6, at I prime negative 7, negative 4
Answer: To find the image of a figure under a translation, you need to apply the same translation to every point in the figure.
In this case, the image of hexagon DEFGHI is hexagon D′E′F′G′H′I′. To find the image of each point, you can apply the translation that maps point D to point D′.
For example, to find the image of point E under the translation, you can apply the same translation that maps point D to point D′:
Point D is located at (2, 5).
Point D′ is located at (-6, -2).
The translation that maps point D to point D′ is a translation 6 units to the left and 2 units down.
To find the image of point E under this translation, you can apply the same translation to point E:
Point E is located at (5, 5).
The image of point E is located at (5 - 6, 5 - 2) = (-1, 3).
You can follow the same process to find the images of the other points under the translation.
Alternatively, you can use the coordinates of point D and point D′ to find the translation vector that describes the translation. The translation vector is a displacement that describes the change in position of a point under the translation.
In this case, the translation vector is given by the displacement from point D to point D′:
Point D is located at (2, 5).
Point D′ is located at (-6, -2).
The translation vector is given by the displacement (-6 - 2, -2 - 5) = (-8, -7).
To find the image of any point under the translation, you can add the translation vector to the coordinates of the point. For example, to find the image of point E under the translation, you can add the translation vector to the coordinates of point E:
Point E is located at (5, 5).
The translation vector is (-8, -7).
The image of point E is located at (5 - 8, 5 - 7) = (-3, -2).
You can follow the same process to find the images of the other points under the translation.

It will take 250 seconds for 30 liters to pass through the pipe.
Step-by-step explanation:
Let's use just the units only to help us set up and equation.
liters/sec × sec = liters
This works. Fill in the numbers we know.
.12 l/sec × ?sec = 30liters
Use a real variable and let's leave off the units so we can write an neater equation to solve.
.12 l/sec × x sec = 30liters
.12x = 30
That's a good equation. Divide by .12 to solve.
x = 30/.12
x = 250
Remember x was seconds. We were asked to find the seconds.
It will take 250 seconds for 30 liters to pass through the pipe.
(In case they ask later, that's 4minutes and 10 seconds)

Cliff takes out a $5,000 personal loan with 7
fixed annual interest compounded monthly to pay for his wedding. He repays the loan in 2 year.s
How much total interest does Cliff pay on his loan?
Cliff pays a total interest of approximately $679.90 on his $5,000 loan.
To calculate the total interest paid on the loan, we need to use the formula for compound interest:
\(A = P(1 + r/n)^{(nt)}\)
Where:
A is the final amount (loan amount + interest)
P is the principal (loan amount)
r is the annual interest rate (in decimal form)
n is the number of times interest is compounded per year
t is the number of years
Given that Cliff takes out a $5,000 loan with a fixed annual interest rate of 7% compounded monthly, we can substitute the values into the formula:
P = $5,000
r = 7% = 0.07
n = 12 (monthly compounding)
t = 2 years
\(A = 5000(1 + 0.07/12)^{(12 \times 2)\)
Calculating this expression:
A ≈ 5000\((1.00583)^{(24)\)
A ≈ 5000(1.13598)
A ≈ 5679.90
The final amount (A) is the loan amount plus the total interest paid. Therefore, to find the total interest paid, we subtract the principal (P) from the final amount (A):
Total Interest = A - P
Total Interest = 5679.90 - 5000
Total Interest ≈ $679.90

Jacy keeps track of the amount of average monthly rainfall in her hometown. She determines that the average monthly rainfall can be modeled by the function ...where ...represents the average monthly rainfall in centimeters and ... represents how many months have passed. If ... represents the average rainfall in July, in which months does Jacy’s hometown get at least 10.5 centimeters of rainfall? Show all of your algebraic reasoning to support your final answer.
Answer:
he months where Jacy's hometown gets at least 10.5 centimeters of rainfall are July (x = 7) and all the months after July, which are August (x = 8), September (x = 9), October (x = 10), November (x = 11), and December (x = 12).
Step-by-step explanation:
The given function is:
f(x) = 0.2x^2 - 1.8x + 6.5
where x represents the number of months passed and f(x) represents the average monthly rainfall in centimeters.
To find the months where the average rainfall is at least 10.5 centimeters, we need to set the function f(x) greater than or equal to 10.5 and solve for x:
0.2x^2 - 1.8x + 6.5 ≥ 10.5
0.2x^2 - 1.8x - 4 ≥ 0
Multiplying both sides by 5, we get:
x^2 - 9x - 20 ≥ 0
We can factor the left-hand side of the inequality as:
(x - 5)(x - 4) ≥ 0
The solution to this inequality is the set of values of x that make the inequality true. This includes the intervals where:
(x - 5) ≥ 0 and (x - 4) ≥ 0, which gives x ≥ 5
OR
(x - 5) ≤ 0 and (x - 4) ≤ 0, which gives x ≤ 4
Thus, the months where Jacy's hometown gets at least 10.5 centimeters of rainfall are July (x = 7) and all the months after July, which are August (x = 8), September (x = 9), October (x = 10), November (x = 11), and December (x = 12).
Jacy's hometown gets at least 10.5 centimeters of rainfall in the months of September, September of the following year, September of the year after that, and so on.
What is inequality?
An inequality is a relation between two numbers or expressions that are not equal.
It can show which of them is greater or smaller by using symbols like < or >. It can also be a statement of fact about the order relationship of quantities.
According to the question given,
We need to solve the inequality:
A(t) ≥ 10.5
Substituting the given function, we get:
2.3sin(π/6)t ≥ 10.5
sin(π/6)t ≥ 4.57.
Since the sine function has a maximum value of 1, the inequality is only satisfied when:
sin(π/6)t = 1
Solving for t, we get:
π/6t = π/2 + 2πk or π/6t = 3π/2 + 2πk
where k is any integer.
Simplifying each equation, we get:
t = 3 + 12k or t = 9 + 12k, where k is any integer.
Therefore, the only solution is given by:
t = 9 + 12k
where k is any integer.
Hence, Jacy's hometown gets at least 10.5 centimeters of rainfall in the months of September, September of the following year, September of the year after that, and so on.

How to calculate volume of a rectangular prism
Calculating the volume of a rectangular prism is a simple process that involves multiplying the length, width, and height.
Calculating the volume of a rectangular prism is a straightforward process. A rectangular prism is a three-dimensional shape that has a length, width, and height. To find its volume, you simply multiply the length by the width by the height. The formula for calculating the volume of a rectangular prism is:
Volume = length x width x height
For example, if a rectangular prism has a length of 5 cm, a width of 4 cm, and a height of 3 cm, its volume would be:
Volume = 5 cm x 4 cm x 3 cm
Volume = 60 cubic centimeters (cm³)
It's important to ensure that all measurements are in the same unit before calculating the volume. For instance, if the length is in meters and the width and height are in centimeters, you would need to convert the length to centimeters to ensure that all measurements are in the same unit before calculating the volume.
In conclusion, calculating the volume of a rectangular prism is a simple process that involves multiplying the length, width, and height. This formula can be used for any rectangular prism regardless of its size or shape.

A loan is being paid off by payments of 1,000, 2,000, ..., 10,000 at the end of years 1, 2, ..., 10.
The effective annual interest rate is 18%.
Determine the amount of interest in the 7th payment.
Therefore, the interest portion of the seventh payment is:7,000 x (1 + r + r2 + r3 + r4 + r5 + r6) / r7 - 7,000.
We have the following payments and their corresponding times of payment:At the end of year 1: $1,000At the end of year 2: $2,000At the end of year 3: $3,000At the end of year 4: $4,000At the end of year 5: $5,000At the end of year 6: $6,000At the end of year 7: $7,000
At the end of year 8: $8,000At the end of year 9: $9,000At the end of year 10: $10,000The present value of these payments is:PMT x [(1 - (1 + r)-n) / r]where PMT is the payment, r is the interest rate per year, and n is the number of years till payment.
For the first payment (end of year 1), the present value is:1,000 x [(1 - (1 + r)-1) / r]which equals
1,000 x (1 - 1 / (1 + r)) / r = 1,000 x ((1 + r - 1) / r) = 1,000
For the second payment (end of year 2), the present value is:2,000 x [(1 - (1 + r)-2) / r]which equals 2,000 x (1 - 1 / (1 + r)2) / r = 2,000 x ((1 + r - 1 / (1 + r)2) / r) = 2,000 x (1 + r) / r2
For the seventh payment (end of year 7), the present value is:
7,000 x [(1 - (1 + r)-7) / r]
which equals
7,000 x (1 - 1 / (1 + r)7) / r = 7,000 x ((1 + r - 1 / (1 + r)7) / r) = 7,000 x (1 + r + r2 + r3 + r4 + r5 + r6) / r7

The Language Arts department conducts a study to see if the number of books a student reads per month affects the score on the SAT Verbal Test. Here is the data that the Language Arts department collected for 8 students. Create the scatter plot for this data set. What is the equation of the line of best fit?
A scatter plot visually represents the relationship between two variables. It shows a positive correlation between the number of books read per month and SAT Verbal Test scores, with the equation y = 6.4828x + 520.6962.
A scatter plot is a graphical representation of a set of data that allows the observer to observe the relationship between two variables. It is used to graphically display how one variable is affected by the other. It is a chart of data points plotted on a two-dimensional graph with one variable represented on the X-axis and the other variable on the Y-axis.
Scatter Plot of the Data: From the data provided by the Language Arts department, we can create the scatter plot as shown below:
Equation of the line of best fit: The line of best fit is a straight line that is used to model the relationship between the two variables. It is determined by minimizing the sum of the squares of the differences between the observed values and the predicted values.
From the scatter plot, we can see that there is a positive correlation between the number of books read per month and the score on the SAT Verbal Test. This suggests that the more books a student reads per month, the higher their score on the SAT Verbal Test.
The equation of the line of best fit for the given data set is y = 6.4828x + 520.6962. Here, y represents the score on the SAT Verbal Test and x represents the number of books read per month.
To find the equation of the line of best fit, we can use a regression analysis tool such as Excel. The regression analysis will give us the values of the slope and intercept of the line of best fit, which we can use to write the equation of the line.

3 1/2 cups can be expressed as the multiplication expression: 3 + 1/2.
How to Write 3 1/2 cups as a multiplication expression using the unit, 1 cup, as a factor.To express 3 1/2 cups as a multiplication expression using the unit "1 cup" as a factor, you can write it as:
3 1/2 cups = (3 + 1/2) cups = 3 cups + 1/2 cup
Since there are 1 cup in each term, we can rewrite it as:
3 cups + (1/2) cup
Now, we can express each term as a multiplication expression:
3 cups = 3 * 1 cup = 3
(1/2) cup = (1/2) * 1 cup = 1/2
Putting it all together, the multiplication expression is:
3 * 1 cup + (1/2) * 1 cup = 3 + 1/2
Therefore, 3 1/2 cups can be expressed as the multiplication expression: 3 + 1/2.
