Answer:

4 $x^{6}$ $y^{7}$

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$

12 $x^{5}$ × $y^{3}$ × $\frac{1}{2}$ x x $\frac{2}{3}$ $y^{4}$

= 12 × $\frac{1}{2}$ × $\frac{2}{3}$ × $x^{(5+1)}$ × $y^{(3+4)}$

= 4 $x^{6}$ $y^{7}$

Alexus [3.1K]

Answer:

It would be the first one (y-2=1/3(x-2))

Step-by-step explanation:

The first one is the same function as y=x(1/3)+(1+1/3) which is the same function as the photo.

A.) The formula for the volume of a sphere is given below and the relationship between the radius r and the diameter d is r=d/2.

Tasya [4]

Answer:

$\displaystyle V=\frac{4}{81}\cdot \pi\ cm^3$

Step-by-step explanation:

<u>The Volume of a Sphere </u>

The volume of a sphere of radius r is given by:

$\displaystyle V=\frac{4}{3}\cdot \pi\cdot r^3$

A. )

If the diameter of the sphere is d, the radius is r=d/2. Substituting:

$\displaystyle V=\frac{4}{3}\cdot \pi\cdot \left (\frac{d}{2} \right )^3$

Operating

$\displaystyle V=\frac{4}{3}\cdot \pi\cdot \frac{d^3}{8}$

Simplifying

$\displaystyle V=\frac{1}{6}\cdot \pi\cdot d^3$

B.)

The diameter of the sphere is 2/3 cm, thus the volume is:

$\displaystyle V=\frac{1}{6}\cdot \pi\cdot \left (\frac{2}{3} \right )^3$

Operating:

$\displaystyle V=\frac{1}{6}\cdot \pi\cdot \frac{8}{27}$

$\displaystyle V=\frac{8}{27}\frac{1}{6}\cdot \pi$

$\boxed{\displaystyle V=\frac{4}{81}\cdot \pi\ cm^3}$
