So,
9x -7 = -7

9 x 0 = 0

0-7=-7
Its because 0 is first so its opposite

9x-7=-7
-7+7=0
9x=0
x=0
Hope this helps :)

Y = cos(x) sqrt(3)/2 = cos(30º) dy = -sin(x)*dx dy = -sin(30º)*(pi/180) = (1/2)*(pi/180) y + dy = cos(x) - sin(x)dx y + dy = sqrt(3)/2 - (1/2)*(pi/180) = 0.8573

Simplify the expression. Assume all variables are positive. <br> (r/32s)^8/5

balandron [24]

Answer:

Step-by-step explanation:

Alright, lets get started.

The given expression is :

$(\frac{r}{32s} )^{\frac{8}{5} }$

It could be written as

$(\frac{r}{s} )^{\frac{8}{5} }*(\frac{1}{32} )^{\frac{8}{5} }$

32 could be written as $2^{5}$

So, replacing that in our expression

$(\frac{r}{s} )^{\frac{8}{5} }*(\frac{1}{2^{5} } )^{\frac{8}{5} }$

$(\frac{r}{s} )^{\frac{8}{5} }*(\frac{1}{2} )^{5*\frac{8}{5} }$

$(\frac{r}{s} )^{\frac{8}{5} }*(\frac{1}{2} )^{8}$

$\frac{1}{256}*(\frac{r}{s} )^{\frac{8}{5} }$

This is the simplified form of given expression. : Answer

Hope it will help :)
