Use a computer algebra system to plot the vector field F(x, y, z) = sin(x) cos2(y)i + sin3(y) cos4(z)j + sin5(z) cos6(x)k in the

Olenka [21]

By the divergence theorem,

$\displaystyle\iint_S\vec F\cdot\mathrm d\vec S=\iiint_{[0,\pi/2]^3}\mathrm{div}\vec F\cdot\mathrm dV$

We have

$\mathrm{div}\vec F(x,y,z)=\cos x\cos^2y+3\sin^2y\cos y\cos^4z+5\sin^4z\cos z\cos^6x$

Then the volume integral is

$\displaystyle\int_0^{\pi/2}\int_0^{\pi/2}\int_0^{\pi/2}\mathrm{div}\vec F\,\mathrm dx\,\mathrm dy\,\mathrm dz=\boxed{\frac{19\pi^2}{64}}$

The simple interest will not always be less than the compound interest on a set of money borrowed.

vaieri [72.5K]

Answer:

False

Step-by-step explanation:

Simple interest is the percentage rate that a borrower pays to borrow money for a set period of time, whereas compound interest is calculated on top of what has already been borrowed, which means that as time passes, more and more interest charges accumulate until repayment begins. e. when a borrower pays interest on the principal plus interest charges that have accrued.

Triangle QRS is reflected over y = 2. What are the coordinates of Q'?

Levart [38]

Answer:

(1,6)

Step-by-step explanation:

In order to reflect a point over a horizontal line, you need to count how many units it takes to reach that line (going vertically). Once you have that number, count that many units starting from that point on the line (again, going vertically), then that is your reflected point.

Counting from point Q to the line y = 2, it takes 4 units. So starting from that point on the line where I left off, I would count another 4 units, taking me to (1,6). The picture below explains it better visually.
