The beer-lambert formula determines the intensity of light in water (measured in lumens) at a depth of x feet. find the intensit

Bezzdna [24]

Answer:

1.324 lumens

Step-by-step explanation:

The Beer-Lambert formula gives the intensity of light in water, at a certain depth x.

In this problem, the formula given is:

$Log_{10}\frac{I}{12}=-0.02735 x$

where

I is the intensity (in lumens)

x is the depth (in feet)

Here we are asked to find the intensity of light at a depth of

x = 32 feet

Therefore, re-arranging the equation and substituting x = 32, we find:

$I=12\cdot 10^{-0.02735x}=12\cdot 10^{-0.02735\cdot 32}=1.324$ lumens

3x3-27x=0<br> Solve by factoring a

Eddi Din [679]

After factoring $3x^3-27x=0$ the solutions are x=0 , x=3, x= -3

Step-by-step explanation:

We need to solve by factoring:

$3x^3-27x=0$

Solving:

$3x^3-27x=0$

Taking 3x common:

$3x(x^2-9)=0$

Now using formula $a^2-b^2=(a-b)(a+b)$

$3x((x)^2-(3)^2)=0\\3x(x-3)(x+3)=0$

$3x=0\,\,and\,\,x+3=0\,\,and\,\,x-3=0\\x=0\,\,and\,\,x=-3\,\,and\,\,x=3\\$

So, After factoring $3x^3-27x=0$ the solutions are x=0 , x=3, x= -3
