(Picture Provided) A line passes through the points
2 answers:
Given that : A line passes through the points (6,5) and (2,2).
We need to select the forms of linear equations given:
First we need to find the slope between (6,5) and (2,2) points first.
So, we got slope of the equation: 3/4.
Taking point (6,5) and slope 3/4.
Using point -slope form y-y1 =m(x-x1), we get
<h3>y-5 = 3/4 (x-6).</h3>Taking point (2,2) and slope 3/4, we get
<h3>y-2 = 3/4 (x-2).</h3><h3>Therefore, correct options are First and Fourth options.</h3><h3 />

Answer:
f(2) = $180.22
f'(2) = $130.00/week
f'(2)/f(2) = 72.13%
Two weeks after the DVD was released, the revenue from sales is $180.22 and is increasing at a rate of $130 per week, or 72.13% per week.
Step-by-step explanation:
The revenue from sales, in dollars, as a function of time, in weeks, is given by:
After two weeks (t=2), the revenue from sales is:
The rate of change, which is given by the derivate of the revenue function, at t = 2 weeks is:
The relative rate of change is:
Therefore, Two weeks after the DVD was released, the revenue from sales is $180.22 and is increasing at a rate of $130 per week, or 72.13% per week.
