If two lines are perpendicular, then the product of their slopes is -1:

From the problem, we identify:

Then, using the equation (1), we calculate the slope of the green line:

Answer: Option D
After thorough research, there exists the same question that ask:
<span>Based on the equation, how much more money, in millions of dollars, was earned in revenue for week 3 than for week 5?</span>
The question will give a high value but nevertheless, it is still answerable.
Function is equal to 73^x
For 3 weeks , we will get
= 73^3 - 73^2
For 5th week = 73^4 x 72
Based on the equation, it is obvious that we get more in 5th week compared to 3rd of around 2 billion.
I believe there is a picture of the situation missing, but we still have all the info necessary to solve.
We take the height, 5, and divide by the slope, 1/12, getting 60. This is the length of the ramp.
60 feet<span />
