Standard form is f(x)=ax²+bx+c

A=(x+4)*(x+8)
=x²+4x+8x+32
=x²+12x+32=f(x)

(10x^3y^-2/5x^-3y^4)^-3, x≠0, y≠0

zhenek [66]

Answer:

$\dfrac{y^{18}}{8x^{18}}$

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

a^-b = 1/a^b

(a^b)^c = a^(bc)

__

Your expression simplifies as follows:

$\left(\dfrac{10x^3y^{-2}}{5x^{-3}y^4}\right)^{-3}=(2x^{3-(-3)}y^{-2-4})^{-3}=(2x^6y^{-6})^{-3}\\\\=(2^{-3})x^{6(-3)}y^{(-6)(-3)}=\dfrac{1}{8}x^{-18}y^{18}\\\\=\boxed{\dfrac{y^{18}}{8x^{18}}}$

Help please to find the stuff

bekas [8.4K]

Answer:

y = (√3)/2

Step-by-step explanation:

The unit circle has equation ...

x^2 +y^2 = 1

For x = 1/2, the value of y can be found to be ...

(1/2)^2 +y^2 = 1

y^2 = 1 - 1/4 = 3/4 . . . . . subtract 1/4

y = √(3/4) . . . . . . . . . . take the square root (y > 0 here)

y = (√3)/2
