Riya applying mulch in m³/ m² at the rate of 0.25 m³
To calculate the rate of mulch application in m³/m², we need to convert the given rate of 250,000 cm³/m² into m³/m². We can do this by using the conversion factor: 1 m³ = 1,000,000 cm³.
So, 250,000 cm³/m² can be converted to m³/m² as follows:
250,000 cm³/m² × (1 m³/1,000,000 cm³) = 0.25 m³/m²
This means that for every square meter of garden space, Riya is applying 0.25 m³ of mulch.
It's important to note that rate refers to the amount of mulch applied per unit of garden space. In this case, the unit is m². By expressing the rate in m³/m², we're specifying the volume of mulch applied per unit of area.

What number must be added to both sides of the equation x2 + 12x = 13 so
that the method of completing the square can be used to solve the roots?
A. 64
B. 49
C. 36
D. 25
The number that must be added to both sides of the equation x2 + 12x = 13 so that the method of completing the square can be used to solve the roots is 36. The correct answer is C. 36.
To complete the square, we need to add the square of half the coefficient of the x term to both sides of the equation. In this case, the coefficient of the x term is 12, so half of it is 6. The square of 6 is 36, so we need to add 36 to both sides of the equation. Hence the correct option is C) 36.
The equation then becomes:
x2 + 12x + 36 = 13 + 36
Simplifying the right side of the equation gives us:
x2 + 12x + 36 = 49
Now we can factor the left side of the equation into a perfect square:
(x + 6)2 = 49
From here, we can use the square root property to solve for x:
x + 6 = ±√49
Solving for x gives us:
x = -6 ± 7
So the roots of the equation are x = 1 and x = -13.

what is the simplest form of the radical expression sqrt2+sqrt3/sqrt2-sqrt3
please show work
Answer:
-5 - 2sqrt6
Step-by-step explanation:
To simplify (sqrt2+sqrt3)/(sqrt2-sqrt3), we can rationalize the denominator, which involves multiplying both the numerator and denominator by the conjugate of the denominator.
The conjugate of sqrt2-sqrt3 is sqrt2+sqrt3, so we can multiply both the numerator and denominator by sqrt2+sqrt3:
(sqrt2+sqrt3)/(sqrt2-sqrt3) * (sqrt2+sqrt3)/(sqrt2+sqrt3) = ((sqrt2+sqrt3)(sqrt2+sqrt3))/((sqrt2-sqrt3)(sqrt2+sqrt3))
Expanding the numerator and simplifying, we get:
(sqrt2+sqrt3)^2 / (sqrt2^2 - sqrt3^2)
= (2 + 2sqrt2sqrt3 + 3) / (2 - 3)
= (5 + 2sqrt6) / (-1)
= -5 - 2sqrt6
Therefore, (sqrt2+sqrt3)/(sqrt2-sqrt3) simplifies to -5 - 2sqrt6.
The simplest form of the expression (√2 + √3) / (√2 - √3) is - (5 + 2√6).
We have,
To simplify the expression (√2 + √3) / (√2 - √3), we can rationalize the denominator by multiplying both the numerator and the denominator by the conjugate of the denominator.
The conjugate of (√2 - √3) is (√2 + √3).
Multiplying the numerator and denominator by (√2 + √3), we get:
[(√2 + √3) x (√2 + √3)] / [(√2 - √3) x (√2 + √3)]
Expanding both the numerator and denominator:
[(√2 + √3)(√2 + √3)] / [√2 x √2 - √2 x √3 + √3 x √2 - √3 x √3]
Simplifying:
[2 + 2√2√3 + 3] / [2 - 3]
Combining like terms:
[5 + 2√6] / [-1]
Since the denominator is -1, we can multiply both the numerator and denominator by -1 to simplify further:
[5 + 2√6] / 1
Finally, we have:
(5 + 2√6)

the missing variable y varies directly with x. If y=75 when x=25, find x when y=25
The answer is value of x when y=25 are 8.33.
The missing variable y varies directly with x, which means that y = kx, where k is a constant.
We can use this equation to find the value of k and then use it to find the value of x when y=25.
First, let's find the value of k:
y = kx
75 = k*25
k = 75/25
k = 3
Now that we know the value of k, we can use it to find the value of x when y=25:
y = kx

x = _____ feet.
The distance from where you launched the ball to the goal is 52.6 feet.
The goal of this problem is to find the distance x from where you launched the ball to the goal. To do this, we can use the trigonometric function tangent. The tangent of an angle in a right triangle is equal to the opposite side divided by the adjacent side. In this case, the opposite side is the distance from where you scored to the sideline (88.1 feet) and the adjacent side is the distance we are trying to find (x).
So, we can set up the equation:
tan(58.828) = 88.1/x
Next, we can cross multiply to get:
x*tan(58.828) = 88.1
Then, we can divide both sides by tan(58.828) to get:
x = 88.1/tan(58.828)
Using the built-in calculator in the right sidebar, we can plug in the values and make sure the setting is on Deg for degrees. This gives us:
x = 88.1/1.6767
Finally, we can round our answer to the nearest tenth of a foot to get:
x = 52.6 feet
So, the distance from where you launched the ball to the goal is 52.6 feet.

The standard deviation of the given data set is 825.87.
How to find standard deviationThe standard deviation of a data set is a measure of how spread out the data is from the mean (average) of the data set. It is calculated using the following formula:
Standard Deviation = √(Σ(x - mean)^2 / n)
Where:
- x is each individual data point
- mean is the average of the data set
- n is the number of data points in the data set
- Σ is the sum of all the values
To calculate the standard deviation of the given data set, we first need to calculate the mean:
Mean = (200 + 1200 + 300 + 350 + 500 + 55 + 10 + 500 + 800 + 850 + 1300 + 2000 + 2100 + 340 + 760 + 830 + 2670 + 9 + 3000) / 20 = 833.45
Next, we need to calculate the sum of the squared differences between each data point and the mean:
Σ(x - mean)^2 = (200 - 833.45)^2 + (1200 - 833.45)^2 + ... + (3000 - 833.45)^2 = 1.365E7
Finally, we can calculate the standard deviation:
Standard Deviation = √(1.365E7 / 20) = 825.87

The Book Barn is having a sale. All hardback

10% off. Suppose you buy four paperbacks
that originally cost $9 each and two
hardbacks that originally cost $20. What
percent of the total have you saved? Round to
the nearest percent.
We have saved approximately 15% of the total cost.
What is the process to calculate the percentage saved in a sale?
When items are on sale, they are usually offered at a discounted price. The percentage saved is a measure of the amount that a buyer has saved on the original price of the item. The process to calculate the percentage saved in a sale involves determining the original price, the discounted price, and then using a formula to find the percentage saved.
The formula for the percentage saved is:
Percentage saved = (Amount saved / Original price) x 100%
Calculation of the total amount saved and the percentage saved :
For the paperbacks, the original price is $9 each and we bought four of them, so the total original price is:
$9/book × 4 books = $36
With a 10% discount, the discounted price of each paperback is:
$9/book × 0.10 = $0.90 discount
$9/book - $0.90 discount = $8.10 discounted price
So, the total discounted price for the four paperbacks is:
$8.10/book × 4 books = $32.40
Therefore, we saved:
$36 - $32.40 = $3.60
For the hardbacks, the original price is $20 each and we bought two of them, so the total original price is:
$20/book × 2 books = $40
With a 20% discount, the discounted price of each hardback is:
$20/book × 0.20 = $4 discount
$20/book - $4 discount = $16 discounted price
So, the total discounted price for the two hardbacks is:
$16/book × 2 books = $32
Therefore, we saved:
$40 - $32 = $8
The total original price of all the books is:
$36 + $40 = $76
The total discounted price of all the books is:
$32.40 + $32 = $64.40
Therefore, we saved:
$76 - $64.40 = $11.60
Plugging in the values , we get:
percentage saved = ($11.60 / $76) × 100%
percentage saved ≈ 15%
Therefore, we have saved approximately 15% of the total cost.

To solve the given linear system, we can use the Gaussian elimination method. This method involves reducing the given matrix to a row echelon form and then solving for the variables using back substitution.
Step 1: Reduce the given matrix to a row echelon form by performing elementary row operations.
\[ \left[\begin{array}{rrr|r} 6 & 2 & -3 & 0 \\ -5 & 3 & 9 & 0 \\ 2 & -7 & -1 & 0 \end{array}\right] \]
We can start by dividing the first row by 6 to get a leading 1:
\[ \left[\begin{array}{rrr|r} 1 & \frac{1}{3} & -\frac{1}{2} & 0 \\ -5 & 3 & 9 & 0 \\ 2 & -7 & -1 & 0 \end{array}\right] \]
Next, we can add 5 times the first row to the second row and subtract 2 times the first row from the third row:
\[ \left[\begin{array}{rrr|r} 1 & \frac{1}{3} & -\frac{1}{2} & 0 \\ 0 & \frac{16}{3} & \frac{17}{2} & 0 \\ 0 & -\frac{23}{3} & 0 & 0 \end{array}\right] \]
Finally, we can multiply the second row by $\frac{3}{16}$ and the third row by $-\frac{3}{23}$ to get a leading 1 in each row:
\[ \left[\begin{array}{rrr|r} 1 & \frac{1}{3} & -\frac{1}{2} & 0 \\ 0 & 1 & \frac{51}{32} & 0 \\ 0 & 1 & 0 & 0 \end{array}\right] \]
Step 2: Use back substitution to solve for the variables.
From the third row, we have:
$x_2 = 0$
Substituting this into the second row gives us:
$x_3 = 0$
And substituting these values into the first row gives us:
$x_1 = 0$

Express the following as a linear combination of u =6, 1,6), v= (1,-1,4) and w = (1,4,7). (23, 10, 23) =_______ U-________ V+_________ +w
Given vectors are, u = (6,1,6), v = (1,-1,4) and w = (1,4,7) and a vector (23, 10, 23).We need to express (23, 10, 23) as a linear combination of u, v and w.
To find the coefficients, we use matrix notation.
Let A be a matrix containing u, v and w as its column matrices, and X be a matrix containing the coefficients.
Then,AX = B Where A = [u | v | w]X = [a | b | c]B = (23, 10, 23)
Therefore, [u | v | w][a | b | c] = (23, 10, 23)⇒ a(u1) + b(v1) + c(w1) = 23a(6) + b(1) + c(1) = 23⇒ 6a + b + c = 23⇒ a(u2) + b(v2) + c(w2) = 10a(1) - b(1) + c(4) = 10⇒ a - b + 4c = 10⇒ a(u3) + b(v3) + c(w3) = 23a(6) - b(4) + c(7) = 23⇒ 6a - 4b + 7c = 23
The above system of linear equations can be solved using Gaussian elimination method.
The row echelon form of the augmented matrix [A | B] is, [6 1 1 | 23][1 -1 4 | 10][0 0 2 | 9]
The solution is, c = 9/2, b = -3, and a = 1/2.
Therefore, (23, 10, 23) = (1/2)u - 3v + (9/2)w can be written as a linear combination of u, v and w.

Point c means that Danny spent $80 dollars on tickets for 5 games . then the unit rate can be represented by the point (5, 80) on the graph.
Explain about the rate of change?The term "rate of change" (ROC) describes the rate at which something evolves over an extended period.
So, it is not the amount of specific features themselves but rather the deceleration or acceleration of changes (— in other words, the rate).Technically speaking, the Price Rate of Change marker calculates the percentage difference in price between the present price and the price from a predetermined number of periods ago.Since it enables investors to identify trends and other trends, rate of change is a crucial financial term.Danny purchases the same number of tickets for every baseball game he attends during the summer, and the graph below shows how much was spent on the X Games in dollars.
Thus, point c means that Danny spent $80 dollars on tickets for 5 games . then the unit rate can be represented by the point (5, 80) on the graph.

Determine whether the complex number is a solution of the equation. 5-i;x^(2)-10x+26=0
That the complex number 5-i is indeed a solution of the equation [tex]x^2-10x+26=0[/tex].
To determine whether the complex number 5-i is a solution of the equation [tex]x^2-10x+26=0[/tex], we can substitute the value of x with the complex number and see if the equation holds true.
Substituting [tex]x = 5-i[/tex] into the equation:
[tex](5-i)^2 - 10(5-i) + 26 = 0[/tex]
Expanding the squared term:
[tex]25 - 10i + i^2 - 50 + 10i + 26 = 0[/tex]
Simplifying the equation:
[tex]25 - 50 + 26 + i^2 = 0[/tex]
Since[tex]i^2 = -1[/tex], we can substitute that value into the equation:
[tex]25 - 50 + 26 - 1 = 0[/tex]
Simplifying further:
[tex]0 = 0[/tex]
Since the equation holds true, we can conclude that the complex number 5-i is indeed a solution of the equation [tex]x^2-10x+26=0[/tex].

Point R is the midponit of XY. If XR = 5x+2 cm and XY= 14x+1 cm , what is the ength of RY in cm ?
Using midpoints, The length of RY is (9x - 1)/2 cm.
What is the midpoint?
A midpoint is a point that is exactly halfway between two other points. In geometry, the midpoint of a line segment is the point on that line segment that is equidistant from both endpoints.
For example, in a line segment AB, the midpoint M is the point on AB that is equidistant from A and B. In other words, the distance from A to M is the same as the distance from M to B. The midpoint M is located at the exact center of line segment AB, and it divides the segment into two equal parts.
The midpoint can also be thought of as the average of the x-coordinates and y-coordinates of the endpoints. For a line segment with endpoints (x1, y1) and (x2, y2), the midpoint has coordinates:
Midpoint = ((x1 + x2)/2, (y1 + y2)/2)
Since R is the midpoint of XY, we know that RX = RY.
We are given that XR = 5x+2 cm and XY = 14x+1 cm.
Thus, RX + RY = XY
Substituting RX = RY, we get:
RY + RY = 14x + 1 - (5x + 2)
Simplifying the right side, we get:
RY + RY = 9x - 1
2RY = 9x - 1
RY = (9x - 1)/2
Therefore, the length of RY in cm is (9x - 1)/2.

Restrict the domain of the function f so that the function is one-to-one and is increasing. Then find the inverse function. State the domains and ranges of both / and /-in interval notation, both fand fin Interval notation.
f(x)=(x+3)2 and its inverse is f -1(x)= f(x)'s domain: F-1(x)'s domain:
f(x)'s range: f(x)'s range:
The domain of f⁻¹(x) is [0, ∞) and the range of f⁻¹(x) is [-3, ∞).
The function f(x)=(x+3)² is not one-to-one, as it is a quadratic function and has a parabolic shape. However, we can restrict the domain of the function so that it is one-to-one and increasing. One way to do this is to restrict the domain to be greater than or equal to the x-coordinate of the vertex of the parabola. The vertex of the parabola is at (-3, 0), so we can restrict the domain to be x ≥ -3. In interval notation, this is [-3, ∞).
The inverse function of f(x) can be found by switching the x and y values and solving for y. This gives us:
x = (y+3)²
√x = y+3
y = √x - 3
So the inverse function is f⁻¹(x) = √x - 3. The domain of the inverse function is the range of the original function, and the range of the inverse function is the domain of the original function. Therefore, the domain of f⁻¹(x) is [0, ∞) and the range of f⁻¹(x) is [-3, ∞).
In summary:
f(x)'s domain: [-3, ∞)
f⁻¹(x)'s domain: [0, ∞)
f(x)'s range: [0, ∞)
f⁻¹(x)'s range: [-3, ∞)

If the money shown is to be divided among 4 people, what should be the first step?
A. Exchange the $100 bill for five $10 bills and one $50 bill.
B. Exchange one $10 bill for ten $1 bills.
C. Exchange the $100 bill for ten $10 bills.
D. Exchange the three $10 bills for thirty $1 bills.
(please help its due today and i dont really understand these questions!!)
Answer:
C. Exchange the $100 bill for ten $10 bills.
Since the money is to be divided among 4 people, it is easier to divide it if the money is in equal denominations. Therefore, the first step should be to exchange the $100 bill for ten $10 bills, so that each person can receive an equal share of $25. This way, we can avoid having to deal with different denominations while dividing the money among the four people.
