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:
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:
lumens
To start off, 5/25 is 1/5. 25 and 5 can both be divided by 5, thus it is 1/5 smiplified. Now you add 12 and it is 12 and 1/5.
Answer:
1 - a/variable
2 - d/statistic
3 - b/population
4 - c/data
5 - e/parameter
6 - f/sample
I did comment asking if the two you'd already selected were definitely correct, but no answer was given, so I apologise if this is wrong. This is what I would put.
We are given the following function and want to find the y-intercept:
Just substitute the value x=0 into the equation to find the value of the y-intercept:
Simplify
Simplify again
Since the value of f(x), or y, when x=0 is 66, the y-intercept of this function is 66.
Let me know if you need any clarifications, thanks!

Equation is
x-6=8
x=8+6
x=14
X equal to 14
