Answer:
See below
Step-by-step explanation:
100 ft in 4 min = 25 ft/min
125 feet in 5 min = 25 ft min
so the height is d = 25 * m d = height m = minutes
25* 8 = 200 feet

Answer:
The perimeter of a rectangle is equal to 2L + 2W, where L = the length of the rectangle and W = the width of the rectangle. So, one equation is
2L + 2W = 60
From the info given in the problem, we also know that L = 4W. Therefore, we can use the Substitution Method to re-write the first equation as:
4W + 2W = 60
You should be able to solve this equation for W. Once you find W, you can then calculate L.

Answer: At x = 2200 level of production, it will get maximum revenue.
Step-by-step explanation:
Since we have given that
p = 55-0.0125x
and Revenue function is given by
We will take the first derivative of it.
Now,we will find the critical points :
and R''(x)=-0.025<0, so it will get maximum revenue.
Hence, At x = 2200 level of production, it will get maximum revenue.
