Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the curves about the given
Fed [463]
See attachment for one such shell. The volume is given by the sum of infinitely many thin shells like this, each with radius x and height determined by the vertical distance between the upper blue curve and the lower orange curve for any given x, i.e. 8e^x-8e^{-x}.

The volume is then

2\pi\displaystyle\int_0^1x\left(8e^x-8e^{-x}\right)\,\mathrm dx=16\pi\int xe^x(e^{2x}-1)\,\mathrm dx=\dfrac{32\pi}9(e^3-4)\approx179.677

Suppose you solved a second-order equation by rewriting it as a system and found two scalar solutions: y = e^5x and z = e^2x. Th
xenn [34]

Answer:

The solutions are linearly independent because the Wronskian is not equal to 0 for all x.

The value of the Wronskian is \bold{W=-3e^{7x}}

Step-by-step explanation:

We can calculate the Wronskian using the fundamental solutions that we are provided and their corresponding the derivatives, since the Wroskian is defined as the following determinant.

W = \left|\begin{array}{cc}y&z\\y'&z'\end{array}\right|

Thus replacing the functions of the exercise we get:

W = \left|\begin{array}{cc}e^{5x}&e^{2x}\\5e^{5x}&2e^{2x}\end{array}\right|

Working with the determinant we get

W = 2e^{7x}-5e^{7x}\\W=-3e^{7x}

Thus we have found that the Wronskian is not 0, so the solutions are linearly independent.

Factor completely. -5 x2y + 10 xy - 15 xy2<br><br> I need help.
ASHA 777 [7]

Answer:

5\,x\,y\,(-x+2-3y)

Step-by-step explanation:

Always proceed by first extracting all common factors to all terms:

Notice that the factors: 5, x, and y are present in all terms, so we can extract them from the trinomial:

-5x^2y+10xy-15xy^2\\5\,x\,y\,(-x+2-3y)

Now, the trinomial left (-x+2-3y) cannot be factored out, so then factoring is complete.
