B - 9 + 6b = 30
You need to add all the b's up on the left side of the equation first. So it rewrites like this:
7b - 9 = 30
next you add 9 to each side to get 7b alone on the left side.
7b = 39
now divide both sides by 7 so that b is all by itself.
b = 5 4/7 or 5.57

Two glasses contain orange juice.

EastWind [94]

Step-by-step explanation:

Amount of orange juice in 400ml glass

= 400ml * (40%/100%) = 160ml.

Amount of orange juice in 300ml glass

= 300ml * (1/2) = 150ml.

Since 150ml < 160ml, the 300ml glass contains less orange juice.

What is the derivative of this function: F(x)=(5e^4x)+(e^-x^6)

Fed [463]

Answer:

$\dfrac{dF(x)}{dx} =20e^{4x}-6x^5e^{x^{-6}}$

Step-by-step explanation:

The derivative of $F(x)$ is calculated as follows:

$\dfrac{dF(x)}{dx}=\dfrac{d}{dx} [(5e^{4x})+(e^{-x^6})]$

$\dfrac{dF(x)}{dx}=\dfrac{d}{dx} [(5e^{4x})]+\dfrac{d}{dx} [(e^{-x^6})]$

$\dfrac{dF(x)}{dx}=5\dfrac{d}{dx} [(e^{4x})]+\dfrac{d}{dx} [(e^{-x^6})]$

using the chain rule we find that

$\dfrac{d}{dx} [(e^{4x})]= \dfrac{d}{d(4x)} [(e^{4x})]+ \dfrac{d}{dx} [4x] = 4e^{4x},$

$\dfrac{d}{dx} [(e^{-x^6})] = \dfrac{d}{d(-x^6)} [(e^{-x^6})]+\dfrac{d}{dx} [(-x^6})]= -6x^5e^{-x^6};$

therefore,

$\dfrac{dF(x)}{dx}=5\dfrac{d}{dx} [(e^{4x})]+\dfrac{d}{dx} [(e^{-x^6})] =5(4e^{4x})-6x^5e^{x^{-6}}$

$\boxed{\dfrac{dF(x)}{dx} =20e^{4x}-6x^5e^{x^{-6}}}$
