Explanation Given: The daily profit P in dollars of Pine Tree Picnic Tables in the summer months is described by the function: P ( x ) = − 5 x 2 + 300 x − 4000 where x is the number of tables that are manufactured in one day. Calculation: Consider the provided profit function, P ( x ) = − 5 x 2 + 300 x − 4000 To find P ( 18 ) , substitute x = 18 in P ( x ) . P ( 18 ) = − 5 ( 18 ) 2 + 300 ( 18 ) − 4000 = − 1620 + 5400 − 4000 = − 220 To find P ( 20 ) , substitute x = 20 in P ( x ) . P ( 20 ) = − 5 ( 20 ) 2 + 300 ( 20 ) − 4000 = − 2000 + 6000 − 4000 = 0 To find P ( 28 ) , substitute x = 28 in P ( x ) . P ( 28 ) = − 5 ( 28 ) 2 + 300 ( 28 ) − 4000 = − 3920 + 8400 − 4000 = 480 To find P ( 35 ) , substitute x = 35 in P ( x )

Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integratio…

Application of Integration

In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.

Volume

In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects th…

Area

Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
