Step-by-step explanation:

Easy:)

$7)4a^{8}b^{12} \\8)25x^{6}y^{8}\\9)x^{9}y^{9}$ × $xy^{2}$

= $x^{10}y^{11}$

$10)a^{3}$ × $a^{8}b^{4}$

= $a^{11}b^{4}$

$11)4a^{2}b^{4}$ × $9a^{4}b^{2}$

$=36a^{6}b^{6}$

Have a nice day! :)

How do you know how many places are in fifty million without writing the number in standard form

Sunny_sXe [5.5K]

The millions place is befor the second comma form left to right and fifty means tens place so skip to the left to times
Example:

     ←LEFT    RIGHT→
tens place →50,000,000
                         ↑
                     Millions

Find the volume V obtained by rotating the region bounded by the curves about the given axis.

BartSMP [9]

Using the disk method, the volume is given by the integral

$\displaystyle \pi \int_{\pi/2}^\pi (9\sin(x))^2\,\mathrm dx = 81\pi \int_{\pi/2}^\pi \sin^2(x)\,\mathrm dx$

That is, each disk has a radius of y = 9 sin(x) and hence area = π (9 sin(x))². Add up infinitely many such disks by integrating. Then the volume is

$\displaystyle 81\pi \int_{\pi/2}^\pi \sin^2(x)\,\mathrm dx = \frac{81\pi}2 \int_{\pi/2}^\pi (1-\cos(2x))\,\mathrm dx \\\\ =\frac{81\pi}2 \left(x-\frac{\sin(2x)}2\right)\bigg|_{\pi/2}^\pi \\\\ = \frac{81\pi}2 \left( \left(\pi-\frac{\sin(2\pi)}2\right) - \left(\frac\pi2 - \frac{\sin(\pi)}2\right) \right) \\\\ = \boxed{\frac{81\pi^2}4}$
