A farmer wants to fence a rectangular garden next to his house which forms the northern boundary. The fencingfor the southern bo
Ivahew [28]

Answer:

10 ft x 10 ft

Area = 100 ft^2

Step-by-step explanation:

Let 'S' be the length of the southern boundary fence and 'W' the length of the eastern and western sides of the fence.

The total area is given by:

A=S*W

The cost function is given by:

\$ 120 = \$3*2W+\$6*S\\20 = W+S\\W = 20-S

Replacing that relationship into the Area function and finding its derivate, we can find the value of 'S' for which the area is maximized when the derivate equals zero:

A=S*(20-S)\\A=20S-S^2\\\frac{dA}{dS} = \frac{d(20S-S^2)}{dS}\\0= 20-2S\\S=10

If S=10 then W =20 -10 = 10

Therefore, the largest area enclosed by the fence is:

A=S*W\\A=10*10 = 100\ ft^2

Answer:

a=14

b=6

c=5

Step-by-step explanation:

x-6\sqrt{x}  + 4 = 0

x +4 =6\sqrt{x}

x^2 + 8x + 16 = 36x

x^2 - 28x + 16 = 0

14 ±6\sqrt{5}
