The the intensity I of light (in lumens) in a certain lake at a depth of x feet is given by log(1/12) = -0.00235x. What is the i

ch4aika [34]

Answer:

11.45 lumens

Step-by-step explanation:

We are given that

$log(I/12)=-0.00235x$

Where x=Depth

I=Intensity of light

We have to find the intensity of the light at a depth of 20 feet.

Substitute the value of x

$log(I/12)=-0.00235\times 20$

$log(I/12)=-0.047$

$\frac{I}{12}=e^{-0.047}$

$I=12e^{-0.047}$

$I=11.45 Lumens$

Hence, the intensity of the light (in lumens) at a depth of 20 feet=11.45 lumens

How do I solve x in a triangle

Sindrei [870]

All three sides always add up to 360 so add the given measures and subtract it from 360 and that would give you your answer.

Pls help in a middle of an exam

KIM [24]

Answer:

$\frac{2x^2+4x-9}{(2x-3)(2x+3)(x-1)}$

Step-by-step explanation:

$\frac{2x}{4x^2-9} + \frac{3}{2x^2+x-3}$ can be simplified to:
$\frac{2x}{(2x-3)(2x+3)}+\frac{3}{(2x+3)(x-1)}$

Make them have common denominators so:
$\frac{(2x)(x-1) +3(2x-3)}{(2x-3)(2x+3)(x-1)}$

Simplify:
$\frac{2x^2-2x+6x-9}{(2x-3)(2x+3)(x-1)} = \frac{2x^2+4x-9}{(2x-3)(2x+3)(x-1)}$

I don't think you can simplify that fraction further so that's the answer.
