Three of the sides will require fencing and the fourth wall already exists. If the farmer has 116 feet of fencing, what are the
dolphi86 [110]

Answer:

29 ft x 58 ft

Step-by-step explanation:

Let x be the length of each side perpendicular to the wall, and y be the length of the side parallel to the wall.

The amount of wire available is:

116 = 2x+y\\y=116-2x

The area of the region is:

A=xy=x(116-2x)\\A(x)=116x-2x^2

The value of 'x' for which the derivate of the area function is zero will yield the maximum area:

A(x)=116x-2x^2\\A'(x) = 116-4x=0\\x=29\ ft

The value of y is:

y=116-2*29\\y=58\ ft

The dimensions of the region with the largest area are 29 ft x 58 ft.

Raul has $460 in his checking account. Each month, $45 is automatically deducted from his account to pay for his cell phone plan
olasank [31]

Answer:

7 Months

Step-by-step explanation:

x=number of months

how much is deducted total=number of months times amount deducted per m onth

amount deducted per month=45

number of months=x

how much deducted total=45x

460-deducted total is more than 100

460-45x>100

solve for x

add 45x to both sides

460>100+45x

subtract 100

360>45x

divide both sides by 45

8>x

answer is 7 months

if he does 8 months, then he will have exatly 100 and 100 is noe more than 100
