When a<0 is the parabols wider or narrower?

The inverse function is given by the set of points {(11, 2), (-4, 3), (-1, 4), (-14, 5), (1, 6)}, the domain of the inverse function is {11, -4, -1, -14, 1}, and the range of the inverse function is {2, 3, 4, 5, 6}.

To find the inverse of the one-to-one function defined by the given set of points {(2, 11), (3, -4), (4, -1), (5, -14), (6, 1)}, we need to swap the x-values with the y-values to obtain the reversed pairs of points.

The inverse function is {(11, 2), (-4, 3), (-1, 4), (-14, 5), (1, 6)}.

The domain of the inverse function is the set of all x-values from the original function, which in this case is {11, -4, -1, -14, 1}.

The range of the inverse function is the set of all y-values from the original function, which in this case is {2, 3, 4, 5, 6}.

Therefore, the inverse function is given by the set of points {(11, 2), (-4, 3), (-1, 4), (-14, 5), (1, 6)}, the domain of the inverse function is {11, -4, -1, -14, 1}, and the range of the inverse function is {2, 3, 4, 5, 6}.

Answer: 84π √(17) (rounded to 3 significant figures)

a) To find the arc length of the given curve we need to first evaluate the derivative of y w.r.t. x:dy/dx = 4. The arclength of the curve is given by L = ∫√(1+(dy/dx)^2) dx The value of dy/dx is already given and hence we can substitute the value and integrate .L = ∫√(1+(4)^2) dx = ∫√(17) dx Between the limits z = 1 and 2, x varies from 9 to 13. We need to substitute these values in the integral. L = ∫√(17) dx = √(17) * [x]9^13= √(17) * [13 - 9]= 4 √(17)Answer: 4√17 (rounded to 3 significant figures)

b) The area of the surface of revolution, A, that is obtained when the curve is rotated by 2 radians about the a-axis is given by:A = ∫2π * y √(1+(dy/dx)^2) dx We know that dy/dx = 4 and the value of y is given by 4x+5.A = ∫2π * (4x+5) √(1+(4)^2) dx= ∫2π * (4x+5) √(17) dx Between the limits z = 1 and 2, x varies from 9 to 13. We need to substitute these values in the integral. A = ∫2π * (4x+5) √(17) dx = 2π * √(17) * ∫(4x+5) dx= 2π * √(17) * [2x^2/2 + 5x]9^13= 2π * √(17) * [(26 + 60) - (18 + 20)]= 84π √(17)

Answer:

C) 5x-70=105

Step-by-step explanation:

As marked in the graph, angle 105 and angle (5x-70) equal to each other because they are vertically opposite angles therefore we have equation C)

To prove the statement, let's assume that a and b are integers such that a is divisible by n and b is divisible by a.

Since a is divisible by n, we can write a = kn for some integer k.

Similarly, since b is divisible by a, we can write b = am for some integer m.Now, let's find the difference a - b:

a - b = kn - am

Factoring out common terms, we get:

a - b = n(k - m)

Since k and m are integers, their difference (k - m) is also an integer.

Therefore, we have expressed a - b as the product of n and an integer (k - m), which means that a - b is divisible by n.

Hence, we have proved that if a and b are integers such that a is divisible by n and b is divisible by a, then a - b is divisible by n, without using any specific theorem from a book.

The Y-intercept (b_0 = 14) represents the predicted value of Y when X is zero.

In the given prediction line equation, Y_i = 14 - 0.2X_i, the Y-intercept is represented by the term '14', which is the coefficient of the constant term.

The Y-intercept, denoted as b_0, represents the predicted value of the dependent variable (Y) when the independent variable (X) is equal to zero. In this case, when X is zero, the equation becomes:

Y_i = 14 - 0.2(0) = 14

Therefore, the Y-intercept (b_0 = 14) represents the predicted value of Y when X is zero. It is the point where the prediction line intersects the Y-axis. In practical terms, it means that when the independent variable has no effect or has a value of zero, the predicted value of the dependent variable is 14.

The animation function in Matlab can be used to visualize the standing wave that is written as(, ) = sin(z) sin (2). Here are the steps to do it:

Step 1: Define the values of x, y, and z coordinates. Let's say we assume the values of x, y, and z coordinates as follows:x = 0:0.01:1;y = 0:0.01:1;z = 0:pi/100:pi;

Step 2: Use meshgrid to create a grid of coordinates from the x, y, and z vectors. This creates a matrix of coordinates that can be used in the sin function. [X,Y,Z] = meshgrid(x,y,z);

Step 3: Use the sin function to calculate the values of the standing wave at each point in the grid. s = sin(Z).*sin(2*X);

Step 4: Use the animation function to visualize the standing wave as it oscillates. Here is the code for this:for i = 1:size(s,3) surf(s(:,:,i)) view(2) shading interp axis tight caxis([-1 1]) drawnow end

The animation function displays the standing wave as it oscillates in the z direction. The surf function is used to create a surface plot of the wave at each time step. The view function sets the camera view to 2D, and the shading interp function interpolates the colors between the vertices of the surface plot. The axis tight function sets the limits of the x, y, and z axis to the range of the data.

The caxis function sets the color scale to -1 to 1, which corresponds to the range of the sin function. The drawnow function updates the plot at each time step.

Step-by-step explanation:

Base times height.

A right-angled Triangle with a base of 5 cm and a hypotenuse of 11 cm. Measure the angle opposite the base using a protractor to obtain the nearest degree measurement.

To construct a right-angled triangle with a base of 5 cm and a hypotenuse of 11 cm, follow these steps:

1. Start by drawing a straight line using a ruler. This will serve as the base of the triangle. Label the endpoints as A and B.

2. Use a compass to draw a circle with a radius of 11 cm, centered at point A. This circle will intersect the base at point C and define the hypotenuse of the triangle.

3. With the compass still set to the radius of 11 cm, draw another circle centered at point C. This circle will intersect the first circle at point D.

4. Connect points B and D with a straight line segment. This line will be perpendicular to the base AB and will form the height of the triangle.

5. Measure the length of the line segment BD using a ruler. If it measures 5 cm, then you have successfully constructed a right-angled triangle with the given dimensions.

6. To find the angle opposite the base, use a protractor to measure the angle at point B. Place the center of the protractor at point B and align the base line AB with the zero-degree mark. Read the angle measurement at the intersection of the protractor and the line segment BD. Round the measurement to the nearest degree.

The angle opposite the base can vary depending on the accuracy of the construction. Measure the angle using the protractor and record the nearest degree measurement.

When performing geometric constructions and providing measurements, it is important to ensure academic integrity and avoid plagiarism. Plagiarism involves using someone else's work or ideas without proper attribution. To maintain originality, it is necessary to express the information in your own words and provide accurate measurements based on the construction process.

In conclusion, by following the steps  construct a right-angled triangle with a base of 5 cm and a hypotenuse of 11 cm. Measure the angle opposite the base using a protractor to obtain the nearest degree measurement.

N+F=42 & F+3N=70 System Solved: Natalie is 14 and Fred is 28

Step-by-step explanation:

Using variables N=natalies age and F=Freds age

N+F=42 ----> N=42-F (take this and plug it into the other equation)

F+3N=70 so F+3(42-F)=70 [simplify] F+126-3F=70 [further simplify]

-2F=-56 [divide -56 by -2] F=28 [then plug this number into the orig. equation]

So N+28=42 or N=14.

What is the question?

I can't see any question.

The eigenvalue of the state equation is -2 and the corresponding eigenvector is [0].

To obtain the eigenvalues and eigenvectors of the given state equation, we need to solve the characteristic equation.

The state equation is represented as follows:

[d/dt]x = -2x + 11u

y = 4x

To obtain the eigenvalues λ, we set up the characteristic equation:

|A - λI| = 0

Where A is the coefficient matrix, λ is the eigenvalue, and I is the identity matrix.

The coefficient matrix A is:

A = -2

The identity matrix I is:

I = 1

Substituting these values into the characteristic equation, we have:

|-2 - λ| = 0

Simplifying the equation, we get:

-2 - λ = 0

Solving for λ, we find:

λ = -2

So, the eigenvalue of the state equation is -2.

To obtain the eigenvector, we substitute the eigenvalue back into the equation (A - λI)x = 0.

For λ = -2, we have:

(-2 - (-2))x = 0

-2x = 0

Solving for x, we find:

x = 0

Therefore, the eigenvector corresponding to the eigenvalue -2 is [0].
