Answer:

30 Lower level tickets

17 upper level tickets

Step-by-step explanation:

Let:

Lower level tickets = l

Upper level tickets = u

5l + 9u = 303 - - - (1)

8l + 10u = 410 - - - - - (2)

Multiply (1) by 8 and (2) by 5

40l + 72u = 2424 - - - (3)

40l + 50u = 2050 - - - (4)

Subtract (3) from (4)

22u = 374

u = 374 / 22

u = 17

Put u = 17 in (1)

40l + 72(17) = 2424

40l + 1224 = 2424

40l = 2424 - 1224

40l = 1200

l = 1200 / 40

l = 30

30 Lower level tickets

17 upper level tickets

The average velocity of the cat during the 62-minute period can be calculated by finding the total displacement and dividing it by the total time taken. The magnitude of the average velocity can be determined using the Pythagorean theorem, and the direction can be found using trigonometry. The average velocity is approximately 2.06 m/min in a direction of 56.3 degrees west of north.

To find the average velocity of the cat, we need to calculate the total displacement and the total time taken. The cat's displacement consists of a northward displacement of 106 m and a westward displacement of 80 m.
The total displacement is found by taking the vector sum of the individual displacements. Using the Pythagorean theorem, we can calculate the magnitude of the total displacement as follows:
Magnitude of displacement = sqrt((106 m)^2 + (80 m)^2) ≈ 130.2 m
The total time taken is the sum of the individual times, which is 47 minutes + 15 minutes = 62 minutes.
The average velocity is then obtained by dividing the total displacement by the total time taken:
Average velocity = 130.2 m / 62 min ≈ 2.10 m/min
To determine the direction of the average velocity, we can use trigonometry. The angle can be found by taking the inverse tangent of the ratio of the northward displacement to the westward displacement:
Angle = tan^(-1)((106 m) / (80 m)) ≈ 52.6 degrees
However, since the displacement is westward, the direction is the supplement of this angle:
Direction = 180 degrees - 52.6 degrees ≈ 127.4 degrees
Therefore, the magnitude of the average velocity is approximately 2.06 m/min, and it is in a direction of 56.3 degrees (180 degrees - 127.4 degrees) west of north.

Step-by-step explanation:

The graph of x ≤ 5  is a vertical line.

Vertical lines have undefined slopes are symbolically represented by the equation, x = a where a is the x-intercept.  The same goes with linear inequalities—you would graph it the same way you normally graph a linear equation.

Another important detail to remember with graphing linear inequalities is the inequality symbol used.  If you have "≤ " or " ≥ ,"  then you will have a solid line for your boundary line. If the linear inequality has "<" or ">," then you will use a dashed line for the boundary line.

To graph x ≤ 5, start at point (5, 0), then draw a vertical line from that point. You will also shade the region below, given the inequality symbol, "≤ ."

Answer: 8.1

Step-by-step explanation:

Use the lower triangle to find one of the sides of the triangle that is composed of the dotted line.

\(4^{2} +5^{2} = c^{2} \\41 = c^{2} \\\sqrt{41} = c\\6.40 =c\)

Use this side value along with what we're given in the image to solve for the length of the dotted line. The image gives us a side length of 5 which we can translate to being equal to the opposite side as well. Now, we have two side lengths and can use Pythagorean theorem to solve for the length of the dotted line:

\(6.40^{2} + 5^{2} = x^{2} \\65.96 = x^{2} \\\sqrt{65.96} = x\\8.1 = x\)

Step-by-step explanation:

To determine the value of the annuity, we need to use the formula for the future value of an ordinary annuity:

A = P * ((1 + r)^n - 1) / r

Where:

A = Value of the annuity

P = Monthly deposit amount

r = Interest rate per period (monthly interest rate in this case)

n = Total number of deposits

First, let's convert the annual interest rate of 5% to a monthly interest rate. We divide the annual interest rate by 12 (number of months in a year) and convert it to a decimal:

Monthly interest rate = 5% / 12 = 0.05 / 12 = 0.0041667

Next, let's substitute the given values into the annuity formula:

P = $50

r = 0.0041667 (monthly interest rate)

n = 60

A = $50 * ((1 + 0.0041667)^60 - 1) / 0.0041667

Now we can calculate the value of the annuity using a calculator or spreadsheet:

A ≈ $50 * (1.0041667^60 - 1) / 0.0041667 ≈ $50 * (1.28370557 - 1) / 0.0041667 ≈ $50 * 0.28370557 / 0.0041667 ≈ $50 * 68.169768 ≈ $3,408.49

The given matrix is A=⎝⎛​104​−121​313​⎠⎞​.

Let Mi​ denote the (i , j) -submatrix of A and you need to fill in the blanks: M2I​=(____ M33​=(____ M12​=(____−).

Here, A is a 3 × 3 matrix and its submatrices Mi​ denote a 2 × 2 matrix that can be obtained by deleting the i-th row and the j-th column of A.

So, we need to determine the given submatrices one by one.

1. M2I​ denotes the (2,1)-submatrix of A. So, deleting the 2nd row and the 1st column of A, we get, M2I​=⎝⎛​−121​313​⎠⎞​2. M33​ denotes the (3,3)-submatrix of A. So, deleting the 3rd row and the 3rd column of A, we get,M33​=⎝⎛​104​−121​⎠⎞​3. M12​ denotes the (1,2)-submatrix of A. So, deleting the 1st row and the 2nd column of A, we get, M12​=⎝⎛​13​−121​⎠⎞​.

Hence, M2I​=⎝⎛​−121​313​⎠⎞​, M33​=⎝⎛​104​−121​⎠⎞​, M12​=⎝⎛​13​−121​⎠⎞​−5.

The percent of change is approximately -15.5% (rounded to the nearest tenth).

To find the percent change between last year's enrollment and this year's enrollment, we can use the following formula

percent change = [(new value - old value) / old value] x 100%

where "new value" is the enrollment for this year, and "old value" is the enrollment for last year

Plugging in the numbers, we get:

percent change = [(87 - 103) / 103] x 100%

percent change = (-16 / 103) x 100%

percent change = -15.53%

Therefore, the percent of change is approximately -15.5% . This means that there was a decrease of about 15.5% in the enrollment for the drama club from last year to this year.

Step-by-step explanation:

a) The equations of the streamlines are: r = c sin(θ)/constant; r = -c cos(θ)/constant. b) For the vortex flow, the time rate of change of the volume of a fluid element per unit volume is zero. c) For the vortex flow, the vorticity is (2 c/r2)e_r.

a) The equations of the streamlines can be obtained by setting the velocity field equal to a constant. This means that u = cy/(x2+y2) = constant and v =-cx/(x2+y2) = constant. To simplify these equations, we can use polar coordinates where x = r cos(θ) and y = r sin(θ). Substituting these into the equations for u and v gives us:
u = c sin(θ)/r = constant
v = -c cos(θ)/r = constant
Solving these equations for r gives us the equations of the streamlines:
r = c sin(θ)/constant
r = -c cos(θ)/constant

b) The time rate of change of the volume of a fluid element per unit volume can be calculated using the divergence of the velocity field. The divergence of the velocity field in polar coordinates is given by:
∇ ⋅ u = (1/r)(∂(r u_r)/∂r + ∂(r u_θ)/∂θ)
Substituting the expressions for u_r and u_θ in terms of u and v gives us:
∇ ⋅ u = (1/r)(∂(r (u cos(θ) + v sin(θ)))/∂r + ∂(r (-u sin(θ) + v cos(θ)))/∂θ)
Substituting the expressions for u and v in terms of c, r, and θ gives us:
∇ ⋅ u = (1/r)(∂(r (c sin(θ)/r cos(θ) - c cos(θ)/r sin(θ)))/∂r + ∂(r (-c sin(θ)/r sin(θ) - c cos(θ)/r cos(θ)))/∂θ)
Simplifying this expression gives us:
∇ ⋅ u = 0
This means that the time rate of change of the volume of a fluid element per unit volume is zero for the vortex flow.

c) The vorticity of the vortex flow can be calculated using the curl of the velocity field. The curl of the velocity field in polar coordinates is given by:
∇ × u = (1/r)(∂(r u_θ)/∂r - ∂u_r/∂θ)e_r + (∂u_r/∂θ - ∂u_θ/∂r)e_θ
Substituting the expressions for u_r and u_θ in terms of u and v gives us:
∇ × u = (1/r)(∂(r (-u sin(θ) + v cos(θ)))/∂r - ∂(u cos(θ) + v sin(θ))/∂θ)e_r + (∂(u cos(θ) + v sin(θ))/∂θ - ∂(-u sin(θ) + v cos(θ))/∂r)e_θ
Substituting the expressions for u and v in terms of c, r, and θ gives us:
∇ × u = (1/r)(∂(r (-c sin(θ)/r sin(θ) - c cos(θ)/r cos(θ)))/∂r - ∂(c sin(θ)/r cos(θ) - c cos(θ)/r sin(θ))/∂θ)e_r + (∂(c sin(θ)/r cos(θ) - c cos(θ)/r sin(θ))/∂θ - ∂(-c sin(θ)/r sin(θ) - c cos(θ)/r cos(θ))/∂r)e_θ
Simplifying this expression gives us:
∇ × u = (2 c/r2)e_r
This means that the vorticity of the vortex flow is (2 c/r2)e_r.

The equation y = x² represents a curve in the set of real numbers2 called a parabola. Hence, the correct option is: Parabola.

What is a parabola?

A parabola is a curve that is shaped like an arch and has one axis of symmetry. The graph of a parabola is U-shaped, and it can open up or down. It is a conic section in geometry, a section of a cone that intersects at a particular angle.

How can you sketch a parabola?

To sketch a parabola, one can use the following steps:

Draw the axis of symmetry and plot the vertex on the line.

Use the axis of symmetry to plot at least two points on one side of the vertex. Then, plot the same points on the other side of the vertex.

Draw a curve through the plotted points that passes through the vertex.

Finally, sketch the graph in both directions until the graph becomes infinitely small or too large.
