Using fencing, a rectangular area is to be enclosed next to the wall of a building. The bullding will form one of the sides and no fencing will be placed there. The cost of the fencing for the side opposite the building is $5 per foot. The cost of the fencing for the other two sides is $3 per foot. The area to be enclosed is 3000 ft². In order to keep expenses of the three sides to a minimum, how many feet of each type of fencing must be bought? 6- a) 100 ft of $3/ft fence, 120 ft of $5/ft fence b) 60 ft of $3/ft fence, 100 ft of $5/ft fence c) 50 ft of $3/ft fence, 120 ft of $5/ft fence Cevap Listesi d) 100 ft of $3/ft fence, 60 ft of $5/ft fence e) 120 ft of $3/ft fence, 50 ft of $5/ft fence
Minimization
In mathematics, traditional optimization problems are typically expressed in terms of minimization. When we talk about minimizing or maximizing a function, we refer to the maximum and minimum possible values of that function. This can be expressed in terms of global or local range. The definition of minimization in the thesaurus is the process of reducing something to a small amount, value, or position. Minimization (noun) is an instance of belittling or disparagement.
Maxima and Minima
The extreme points of a function are the maximum and the minimum points of the function. A maximum is attained when the function takes the maximum value and a minimum is attained when the function takes the minimum value.
Derivatives
A derivative means a change. Geometrically it can be represented as a line with some steepness. Imagine climbing a mountain which is very steep and 500 meters high. Is it easier to climb? Definitely not! Suppose walking on the road for 500 meters. Which one would be easier? Walking on the road would be much easier than climbing a mountain.
Concavity
In calculus, concavity is a descriptor of mathematics that tells about the shape of the graph. It is the parameter that helps to estimate the maximum and minimum value of any of the functions and the concave nature using the graphical method. We use the first derivative test and second derivative test to understand the concave behavior of the function.
