Answer:

$20\pi$

Step-by-step explanation:

Let the radius of the disk be r centimeters. Since the area of the disk is 100pi sq cm, we have $\pi r^2=100\pi$ , and since r is positive, $r=10.$ The circumference of a circle is $2\pi r$ , which, in this case, is $\boxed{20\pi}$ .

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.

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