Use calculus to find the largest possible area for a rectangular field that can be enclosed with a fence that is 500 meters long
rewona [7]
Let x and y be the sides of the rectangle. The perimeter is given to be 500m, so we are maximizing the area function A(x,y)=xy subject to the constraint 2x+2y=500.

From the constraint, we find

2x+2y=500\implies x+y=250\implies y=250-x

so we can write the area function independently of y:

A(x,y)=\hat A(x)=x(250-x)=250x-x^2

Differentiating and setting equal to zero, we find one critical point:

\dfrac{\mathrm d\hat A(x)}{\mathrm dx}=250-2x=0\implies x=125

which means y=250-125=125, so in fact the largest area is achieved with a square fence that surrounds an area of A(125,125)=125^2=15625\text{ m}^2.

Julio's age is 3 times Sally's age plus 2. Sally's age is Julio's age minus 14 what is the difference in their ages?
mojhsa [17]
J = 3S + 2
S = J - 14

S = 3S + 2 - 14
S - 3S = 2 - 14
-2S = - 12
S = -12/-2
S = 6

J = 3S + 2
J = 3(6) + 2
J = 18 + 2
J = 20

and the difference is : 20 - 6 = 14 <===
