Answer:
The largest area enclosed is A = xy = 6 feet
6 feet = 36 ![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
Step-by-step explanation:
i) The perimeter of the area is 2
(x + y) =24 ∴ x + y = 12 ∴ y = 12 - x
ii) The area of rectangle enclosed A = xy ⇒ A = x ( 12 - x) = 12x - ![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
iii) differentiating both sides of the equation in ii) we get
⇒ x = 6 feet
iv) Differentiating both sides of equation in iii) we get
= -2
Therefore the area enclosed is maximum as the double derivative is negative
v) therefore for largest area enclosed x = 6 feet and y = 12 - 6 = 6 feet
vi) therefore the largest area enclosed is
A = xy = 6 feet
6 feet = 36 ![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
Answer:
I think its uh carrot
Step-by-step explanation:
If the line is pointing down it's negative. if the line is pointing up it's positive. if the line is steep is one of the whole numbers and if the line is more shallow it's one of the fractions. -it's positive 3.
A penny is 1.52 mm, so 10 pennies are 15.2 mm. 15.2 mm=1.52 cm
So a stack of 10 pennies is 1.52 centimeters<span />
