Answer:

V = 1152π in³

Step-by-step explanation:

The formula for the volume of a hemishere is

$\frac{ \frac{4}{3}\pi {r}^{3} }{2}$

Next we need to substitute the values from the question in.

$\frac{ \frac{4}{3}\pi {12}^{3} }{2}$

Then finally we need to simplify.

$\frac{2304\pi}{2} = 1152\pi$

Find the slope of the line that passes through the points (10,8) and (4,12)

JulsSmile [24]

Answer:

The slope is -2/3

Step-by-step explanation:

To find the slope of a line between two points, we use the equation

m = (y2-y1)/ (x2-x1)

where (x1,y1) and (x2,y2) are the two points

m = (12-8)/(4-10)

= 4/-6

= -2/3

The slope is -2/3

$\text{The scientific notation:}\\\\a\times10^n\\\\1\leq a$

$a.\\(5\times10^3)\times(3.5\times10^{-1})=(5\times3.5)\times(10^3\times10^{-1})\\\\=15.75\times10^{3+(-1)}=15.75\times10^2=1.575\times10\times10^2\\\\=1.575\times10^{1+2}=\boxed{1.575\times10^3}$

$b.\\(8\times10^2)\div(4\times10^3)=(8\div4)\times(10^2\div10^3)=2\times10^{2-3}\\\\=\boxed{2\times10^{-1}}$

$c.\\(6\times10^{-3})^2=6^2\times(10^{-3})^2=36\times10^{-3\cdot2}=36\times10^{-6}=3.6\times10\times10^{-6}\\\\=3.6\times10^{1+(-6)}=\boxed{3.6\times10^{-5}}$

$Used:\\\\a^n\times a^m=a^{n+m}\\\\a^n\div a^m=a^{n-m}\\\\(a^n)^m=a^{n\cdot m}$
