Arectangular area of 2,000 square feet is to be fenced on three sides with fence costing $0.30 per foot and on the fourth side with fence costing $0.50 per foot. if x denotes the length of the fourth side and c = ƒ( x ) denotes the corresponding cost of the fence in dollars. express c as a function of x .

f(x) = 0.80x +

Step-by-step explanation:

Let a rectangular area is having two sides = x foot and other two sides measure = y foot

As per the statement given in the question, if C is the cost to fence three sides (two sides with y foot and one side with measure x)

C = f(x) = 0.30(2y+x) + 0.50(x)

C = 0.60y + 0.30x + 0.50x

C = 0.80x + 0.60y

We know area of a rectangle is represented by

A = xy

2000 = xy

Now we replace the value of y in equation 1

C =

f(x) = 0.80x +

Therefore, the cost to fence the rectangular area can be represented by

C = f(x) = 0.80x +

Step-by-step explanation:

A bar of gold is an inanimate object, meaning its not living nor dead, so cells do not make up this object, and atoms make everything that isnt living, or dead for that matter
