Let the length = x
2 lengths are 2x.
Then you have 400 - 2x for both widths, so the width is 200 - x.
The are if the rectangle is
y = x(200 - x)
y = 200x - x^2
y = -x^2 + 200x
Take the first derivative ans set equal to zero to find a maximum value.
y' = -2x + 200
-2x + 200 = 0
-2x = -200
x = 100
Since the side of the rectangle is 100, all sides measure 100 ft, and you have a square.
The maximum area is 100 ft * 100 ft = 10,000 ft.
Answer:
The slope is
Step-by-step explanation:
∵ The rule of the slope passing through 2 points is:
m =
∵ The points are (7 , 8) and (-7 , 1)
∴ m =
The weight of wrestler was 80 kg before the special diet
Step-by-step explanation:
Given function is:
We can substitute the values of t to find the weight after t number of months
When we have to find the initial weight , t has to be put equal to zero
So,
Hence,
The weight of wrestler was 80 kg before the special diet
