Determine the area of the shaded region express your answer in simplest form?
erica [24]

Without so much as a quick peek at the picture, it's not possible to even begin
to answer the question.  That's the reason, you see, that the picture is printed
right there, along with the question, in the same place from which you copied
this cut-off portion of the question.  It's not enough.  We need the picture too.

F(x)=x-7; vertical stretch of 3 g(x)
marissa [1.9K]

The function that represents the vertical stretch by a factor of 3 of f(x) is given as follows:

g(x) = 3x - 21.

<h3>How are vertical stretches and compression applied to the graph of a function f(x)?</h3>

Vertical stretches or compression to the graph of a function f(x) are applied by the multiplication of a constant a to the function, as follows:

g(x) = a x f(x).

Then the value of the constant determines if it is an stretch or a compression.

  • If the absolute value of the constant a is <u>greater than 1</u>, it is a stretch.
  • If the absolute value of the constant a is <u>less than 1</u>, it is a compression.

For this problem, we want a vertical stretch with a factor of 3, then the constant is given as follows:

a = 3.

Then the definition of function g(x) is given by:

g(x) = 3f(x)

g(x) = 3(x - 7)

g(x) = 3x - 21.

Consider the initial value problem for the vector-valued function x, x′=Ax,A=[1−225],x(0)=[1−1] Find the eigenvalues λ1,λ2 and t
lilavasa [31]

Answer:

Step-by-step explanation:

Consider the matrix \begin{matrix} 1 & -2 \\ 2 & 5 \end{matrix}. We will calculate the correspondent eigenvalues and eigen vector of the matrix. REcall that, to calculate the eigenvalues of a square matrix A, we must solve the following equation \text{det}(A-\lambda I ) =0 where I is the identity matrix. In this case we have the following

\text{det}\left(\begin{matrix} 1-\lambda & -2 \\ 2 & 5-\lambda \end{matrix}\right) =

which gives us the following polynomial (known as the characteristic polynomial of the matrix A).

(1-\lambda)(5-\lambda)+4 =0 = \lambda^2-6\lambda + 9 = (\lambda -3)^2.

Hence, the only eigenvalue of the given matrix is \lambda = 3.

For us to calculate the eigenvalue, we want to find a base for the Kernel of matrix A-\lambda I replacing the value of lambda with the value of the eigen value. REcall that finding the base for the Kernel is solving the associated homogeneus system of the matrix

\left[\begin{matrix} -2 & -2 \\ 2 & 2 \end{matrix}\right]= \left[\begin{matrix} 0 \\ 0 \end{matrix}\right]

which lead us to the equation -2x-2y=0 or equivalently, y=-x. Hence, the solution of the system is of the form (x,y) = (x,-x) = x(1,-1). So  the correspondent eigenvector is the vector (1,-1).
