Total before tax: $118

Total after tax: $102.66

Step-by-step explanation:

For A, we add the cost of the shirt and jeans to get the total before tax.

$39.20 + $79.80 = $118.00

For the total, after 13% we see how much 1% is.

1% of $118 is $1.18

$1.18 * 13 = $15.34.

$118 - $15.34 = $102.66

Displacement is calculated as the shortest distance between starting and final point which prefers a straight-line path over curved paths.

Displacement is the distance between two different positions of an object in m motion. So, it depends on the initial position and its final position. Also, displacement is the minimum distance between the starting and final positions.

Suppose a body is moving in two different directions x and y then the Resultant Displacement will be S=√x²+y²

Example 1: The path distance from the garden to a school is 5 m west and then 4 m south. A builder wants to build a short-distance path for it. Find the displacement length of the shortest path.

Solution: Distance to the west x = 5 m

Distance to the south y = 4 m.

Displacement is given by S=√x²+y²

s = 6.403 m.

The builder can build a path for a displacement length of 6.7 m.

The formula to solve the displacement is written as Δx  = xf − xi

The term displacement is defined as  the change in the position of any point or object. It has a direction and magnitude, so it is a vector quantity and it is shown with an arrow that points from the starting position to the final position.

In order to find the displacement by determining the object’s initial and final position.

Therefore, the displacement formula is written as,

=> Δx  = xf − xi

Here xf refers the final position,

And the variable xi is the initial position, and

Answer:

The percentage that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8)  = 83.9≅ 84 percentage

Step-by-step explanation:

Step(i):-

Mean of the Population = 8.3 points

Standard deviation of the Population = 0.5 points

Let 'X' be the random variable in normal distribution

Let X = 6.8

\(Z = \frac{x-mean}{S.D} = \frac{6.8-8.3}{0.5} = -3\)

Let X = 8.8

\(Z = \frac{x-mean}{S.D} = \frac{8.8-8.3}{0.5} = 1\)

The probability that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8) = P(-3≤Z≤1)

                     = P(Z≤1)- P(Z≤-3)

                    =  0.5 + A(1) - ( 0.5 -A(-3))

                   = A(1) + A(3)       (∵A(-3)=A(3)

                  =  0.3413 +0.4986    (∵ From Normal table)

                 = 0.8399

Conclusion:-

The percentage that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8)  = 83.9≅ 84 percentage

The expressions that represent the amount of money Jezzabelle has are:
A. 3n
B. n + n + n
C. 3n^2
D. 3n^2
The expressions that represent the amount of money Jezzabelle has are 3n and n + n + n.

Since each stack has the same amount of coins and each stack contains only one type of coin, we can represent the number of coins in each stack as n. Since Jezzabelle has three stacks, the total number of coins she has is 3n, which represents expression A.
Another way to represent the total number of coins is by adding the number of coins in each stack, which would be n + n + n. This represents expression B.
Expressions C and D, 3n^2 and 2n^2, do not correctly represent the amount of money Jezzabelle has because they involve squaring the number of coins in each stack, which is not specified in the problem statement. Therefore, expressions C and D are not applicable in this context.

Answer:

x° = 50°

y° = 70°

z°  = 60°

p° = 50°

(p + 10)° = 60°

(p + 20)° =70°

Step-by-step explanation:

Angles with measurements (p + 20), p and (p + 10) degrees are all on the same line. Therefore these three angles are supplementary angles. In other words the sum of these angles = 180°

Plugging in the expressions for these angles we get

(p + 20 ) + p + (p + 10) = 180°

3p + 30 = 180

Subtracting 150 from both sides,
3p = 180 - 30  = 150

p = 150/3 = 50

x is a vertically opposite angle to p.

Therefor x = p = 50°

y is vertically opposite and equal to p + 20
y = p + 20 = 50 + 20 = 70°

z is vertically opposite and equal to p + 10
z = p + 10 = 50 + 10 = 60°

Step-by-step explanation:

Given

\(\frac{x-2}{2}\) + \(\frac{x-2(x-4)}{6}\) = \(\frac{x}{3}\)

Multiply through by 6 ( the LCM of 2, 6, 3 ) to clear the fractions

3(x - 2) + x - 2(x - 4) = 2x ← distribute parenthesis on left side

3x - 6 + x - 2x + 8 = 2x

2x + 2 = 2x ( subtract 2 from both sides )

2x = 2x - 2 ( subtract 2x from both sides )

0 = - 2 ← not possible

This indicates the equation has no solution

The values of a and b are given as follows:

The expression for this problem is given as follows:

2 - (x + 3)/(x - 4) - (x - 7)/(x + 4)

The least common multiple of the denominators is given as follows:

(x - 4)(x + 4).

Hence the numerator is obtained as follows:

N = 2(x - 4)(x + 4) - (x + 3)(x + 4) - (x - 7)(x - 4)

N = 2(x² - 16) - (x² + 7x + 12) - (x² - 11x + 28)

N = 2x² - 32  - x² - 7x - 12 - x² - 11x - 28

N = -18x - 72.

Hence the values of a and b are given as follows:

a = -18, b = -72.

The solution to the differential equation\(\(xy' = y + 8x\ln(x)\) with the initial condition \(y(1) = 6\) is \(y = 4x\ln(x) - 2x + \frac{8}{x}\).\)

To solve the differential equation\(\(xy' = y + 8x\ln(x)\)\) using integrating factors, we follow these steps:

Step 1: Rewrite the equation in the form \(\(y' + P(x)y = Q(x)\), where \(P(x)\) is the coefficient of \(y\) and \(Q(x)\)\) is the remaining term on the right side.

Divide the equation by

\(\(x\) to obtain:\[y' = \frac{y}{x} + 8\ln(x)\]Here, \(P(x) = \frac{1}{x}\) and \(Q(x) = 8\ln(x)\).\)

Step 2: Determine the integrating factor, denoted as I(x), which is defined as \(\(I(x) = e^{\int P(x) dx}\).\\In this case, \(P(x) = \frac{1}{x}\), so we have:\[I(x) = e^{\int \frac{1}{x} dx} = e^{\ln(x)} = x\]\)

Step 3: Multiply both sides of the equation by the integrating factor\(\(I(x)\):\[xy' + \frac{y}{x} = 8\ln(x) \cdot x\]Simplifying:\[xy' + y = 8x\ln(x)\]\)

Step 4: Recognize the left side as the derivative of the product of \(\(xy\):\[\frac{d}{dx}(xy) = 8x\ln(x)\]\)

Step 5: Integrate both sides of the equation:

\(\[\int \frac{d}{dx}(xy) dx = \int 8x\ln(x) dx\]\[xy = \int 8x\ln(x) dx\]\)

Step 6: Evaluate the integral on the right side:

\(\[xy = 8\int x\ln(x) dx\]\)

Integration by parts is required for \(\(\int x\ln(x) dx\):\[u = \ln(x), \quad dv = x dx\]\[du = \frac{1}{x} dx, \quad v = \frac{1}{2}x^2\]\)

Using the integration by parts formula, we have:

\(\[xy = 8\left(\frac{1}{2}x^2\ln(x) - \int \frac{1}{2}x^2 \cdot \frac{1}{x} dx\right)\]\)

Simplifying:

\(\[xy = 4x^2\ln(x) - 4\int x dx\]\[xy = 4x^2\ln(x) - 2x^2 + C\]\)

Step 7: Solve for \(y\) by dividing both sides by\(\(x\):\[y = 4x\ln(x) - 2x + \frac{C}{x}\]\)

Step 8: Use the initial condition \(\(y(1) = 6\)\) to find the value of the constant \(\(C\):\[6 = 4(1)\ln(1) - 2(1) + \frac{C}{1}\]\[6 = 0 - 2 + C\]\[C = 8\]\)

Therefore, the solution to the given differential equation with the initial condition is:

\(\[y = 4x\ln(x) - 2x + \frac{8}{x}\]\)

In this problem, we are given the vector space V = C^2 and two subspaces W and U defined by certain conditions. We are required to find a basis for the intersection of W and U.

2.1 To find a basis for W ∩ U, we need to determine the common vectors that satisfy the conditions of both subspaces W and U. By substituting the equations defining W and U, we can solve for the values of z1 and z2 that satisfy both equations. The resulting vectors form a basis for W ∩ U.

2.2 To express a given vector (z1, z2) in V as a sum of vectors from W and U, we need to find vectors w ∈ W and u ∈ U such that (z1, z2) = w + u. We can substitute the equations defining W and U into the expression and solve for the values of z1 and z2 that satisfy the equations. The resulting vectors w and u form the desired representation.2.3 Whether V = W ⊕ U depends on whether the sum of W and U spans the entire vector space V and whether the intersection of W and U is trivial (i.e., only the zero vector). If the sum of W and U spans all of V and the intersection of W and U is only the zero vector, then V is equal to the direct sum of W and U.

By applying the given conditions and solving the equations, we can find a basis for W ∩ U, express vectors in V as a sum of vectors from W and U, and determine if V is equal to the direct sum of W and U based on the properties of vector spaces and subspaces.

x = friends that paid discount price = 8

y = friends that paid regular price = 4

Step-by-step explanation:

Let

x = friends that paid discount price

y = friends that paid regular price

x + y = 12 (1)

6x + 8y = 80 (2)

From (1)

x = 12 - y

Substitute x = 12 - y into (2)

6x + 8y = 80 (2)

6(12 - y) + 8y = 80

72 - 6y + 8y = 80

- 6y + 8y = 80 - 72

2y = 8

y = 8/2

y = 4

Substitute y = 4 into (1)

x + y = 12 (1)

x + 4 = 12

x = 12 - 4

x = 8

x = friends that paid discount price = 8

y = friends that paid regular price = 4
