Different two dimensional figure give different three dimensional figure .

A cone is formed by rotating a right triangle about any line,a sphere is formed by rotating a circle .

If we look at the figure formed by rotating a rectangle around a line the three dimensional figure formed is a cylinder.

The answer is option b)cylinder .

Let u = <-9, 4>, v = <8, -5>. Find u - v. <br> URGENT

Pie

To subtract vectors, you simply have to subtract correspondent coordinates.

So, if you have

$u = \langle u_1,\ u_2,\ldots u_n\rangle ,\quad v = \langle v_1,\ v_2,\ldots v_n\rangle$

the subtraction is simply

$u-v = \langle u_1-v_1,\ u_2-v_2,\ldots u_n-v_n\rangle$

So, in your case, we have

$\langle-9,4\rangle-\langle 8,-5\rangle=\langle -9-8, 4+5\rangle=\langle -17,9\rangle$
