step 1
we have the curve
Find out the derivative
step 2
Find out the equation of the line perpendicular to the given curve that passes through the point (0,8)
Remember that
If two lines are perpendicular, then their slopes are negative reciprocal
so
The slope of the perpendicular line is m=-1/2
The equation of the line is given by
where
m=-1/2
point (0,8) ----> y-intercept
substitute
step 3
Find out the intersection of both lines
Equate both equations
Find out the y-coordinate of the point
<h2>The coordinates of the point are</h2>

For 1 cow, it takes 400 people to take Care of it. So for 50 cows, it would be 400x50. which is 20,000
we simply divide the whole by the sum of the ratios, namely 28 by (3+4), and then distribute accordingly.
