The variation equation if y varies jointly with x and z and y = 360 when x =12 and z = 15 is y = 2xz.

The variation equation for this situation can be represented as the equation y = kxz, where k is the constant of variation, since y varies jointly with x and z.

We can find the value of k by plugging in the given values of x, y, and z into the equation and solving for k:

360 = k(12)(15)

360 = 180k

2 = k

So, the constant of variation is 2. Hence, the variation equation is y = 2xz. This equation can be used to find the value of y for any given values of x and z. For example, if x = 4 and z = 10, then y = 2(4)(10) = 80.

The flux of the vector-field F = 1i + 1j + 2k across the surface S is 2. We find out the flux of the vector-field using Green's Theorem.

Flux form of Green's Theorem for the given vector-field

φ = ∫ F.n ds

= ∫∫ F. divG.dA

Here G is equivalent to the part of the plane = 2x+4y+z = 2.

and given F = 1i + 1j + 2k

divG = div(2x+4y+z = 2) = 2i + 4j + k

Flux = ∫(1i + 1j + 2k) (2i + 4j + k) dA

φ = ∫ (2 + 4 + 2)dA

= 8∫dA

A = 1/2 XY (on the given x-y plane)

2x+4y =2

at x = 0, y = 1/2

y = 0, x = 1

1/2 (1*1/2) = 1/4

Therefore flux = 8*1/4 = 2

φ = 2.

Answer:

x = 12°

Step-by-step explanation:

The measures of the exterior angles of a hexagon are x°, 2x°, 5x°, 6x°, 7x°, and 9x°. Solve for x.

The sum of the exterior angles of a polygon sums up to 360

An hexagon is a 6 - sided polygon

(x + 2x + 5x + 6x + 7x + 9x) = 360

30x = 360

Divide both sides by 30

x = 360 / 30

x = 12

Hence, x = 12°

The coordinates of the partition point of line segment are (3, -1)

This is the partition of a line into segments.

Since the we require  the coordinates of the point on the directed line segment from (-5,5) to (7,-4) that partitions the segment into a ratio of 2 to 1, we use the equation for the internal division of a  line.

This is the division of a line into segments internally.

The coordinates of the point that divides the line with end points (x₁, y₁) and (x₂, y₂) in the ratio m:n are

Given that

Substituting the values of the variables into the equation, we have

x = (mx₂ + nx₁)/(m + n)

= (2(7) + 1(-5))/(2 + 1)

= (14 - 5))/3

$484,835 is the amount that separates the lowest 20% of the means of retirement accounts from the highest 80% of the means of retirement accounts.

Given Information:

Mean of retirement accounts = μ = $490,000

Standard deviation of retirement accounts = σ =  $55,000

Sample size = n = 80

We are given a Normal Distribution, which is a continuous probability distribution and is symmetrical around the mean. The shape of this distribution is like a bell curve and most of the data is clustered around the mean. The area under this bell shaped curve represents the probability.  

The amount of money that separates the lowest 20% of the means of retirement accounts from the highest 80% is given by

\(P\frac{( \bar x - \alpha )}{\frac{\sigma}{\sqrt{n} } }\)

The z-score corresponding to 0.20 is -0.84

\(\bar x = \alpha + z.\frac{\sigma }{\sqrt{n} } \\\\\bar x = 490,000 - 0.84 .\frac{55,000}{\sqrt{80} } \\\\\bar x = 490,000 - 5165.32\\\\\bar x = 484,834.68\)

Rounding off to the nearest whole number

\(\bar x = $484,835\)

Therefore, $484,835 is the amount that separates the lowest 20% of the means of retirement accounts from the highest 80% of the means of retirement accounts.

Answer:

(4,4)

Step-by-step explanation:

The solution set of the system of equations can be found by setting the two equations equal to each other and solving for x.

x^2 - 6x + 12 = 2x - 4

x^2 - 8x + 16 = 0

(x - 4)^2 = 0

x = 4

Since both equations in the system are equal to y, we can substitute x = 4 into either equation to find the corresponding value of y.

y = 2x - 4 = 2(4) - 4 = 4

Therefore, the solution of this system of equations is (4, 4).

Therefore, the correct answer is (4, 4).

The exact value of the letter D is three and three-tenths.

By observing the number line there are 10 subsections between two integers.

The letter D is in between two integers 3 and 4 so it can be from 3.1 to 3.9.

In between those ten subsections, the letter D is in the third subsection.

j) The division of (3.1x10) by (1.5x\(10^{-1\)) equals 2.07x\(10^1\).

i) To multiply numbers in scientific notation, we multiply the coefficients (3.1 and 1.5) and add the exponents (0 and 1) together. In this case, 3.1 multiplied by 1.5 gives us 4.65. Adding the exponents, \(10^0\) multiplied by \(10^1\) results in \(10^1\). Therefore, the final result is 4.65x\(10^1\).

j) When dividing numbers in scientific notation, we divide the coefficients (3.1 and 1.5) and subtract the exponents (1 and -1) from each other. Dividing 3.1 by 1.5 gives us approximately 2.07. Subtracting the exponents, \(10^1\)divided by \(10^{-1\) is equivalent to \(10^{(1-(-1))}\) which simplifies to 10^2. Hence, the result is 2.07x\(10^1\).

A graduated cylinder is a common laboratory instrument used to measure the volume of liquids. The unit of measurement used for a graduated cylinder depends on the markings on the cylinder itself.

In most cases, graduated cylinders are marked in milliliters (mL). This means that the cylinder is calibrated to measure volumes of liquid in units of milliliters. Milliliters are a standard unit of measurement for liquid volume in the metric system.

However, it is possible for a graduated cylinder to be marked in other units of measurement, such as liters or fluid ounces. In these cases, the cylinder would be calibrated to measure volumes of liquid in those specific units.

It is important to note that when using a graduated cylinder, the user should always read the volume at the bottom of the meniscus, which is the curved surface of the liquid in the cylinder. This ensures the most accurate measurement possible.

T(U) is a subspace of W Since V is a subspace of U, the zero vector of V, 0, is in U. As T is linear, \(T(0) = 0_w\) , where \(0_w\)  is the zero vector of W. Therefore, \(0_{w}\) is in T(U).

It can be proved  Since U is a subspace of V, the zero vector of V, 0y, is in U. Since T is linear, \(T(0_{y}) = 0_{w}\) , where \(0_{w}\) is the zero vector of W. So\(0_{w}\)  is in T(U).

To show that T(U) is a subspace of W, we also need to show that T(U) is closed under vector addition and scalar multiplication. Let u1, u2 be vectors in U, and let c be a scalar. Then we have: \(T(u1 + u2) = T(u1) + T(u2)\)  (since T is linear)

\(T(cu1) = cT(u1)\)  (since T is linear)

Since U is a subspace of V, we have \(u1 + u2\) and \(cu1\)  are also in U. Therefore, \(T(u1 + u2)\)  and \(T(cu1)\)  are both in T(U), which shows that T(U) is closed under vector addition and scalar multiplication.

Thus, T(U) is a subspace of W.
